Hi,

Summary of informations from this thread:

Reposetory with my changes for rpcminer-mod (only Cuda): https://github.com/psychocoderHPC/rpcminer-mod
Reposetory with all changes and windows support (CUDA und OpenCL) (administrated by charliemaggot): https://github.com/cdmackie/rpcminer-mod

Known CUDA Errors unter Windows:
- cudart32_50.dll or cudart32_50.dll is missing    -> install https://developer.nvidia.com/cuda-downloads to solve this problem
- bitcoinminercuda.cpp:174 crash -> this means that the kernel run longer than windows allow, to solv this add the paramter -gpugrid 256 or other number to the parameters

Original Post:

I have changed the code of rpcminer-mod https://github.com/Ang3lus/rpcminer-mod a little bit thus we get better performance on Kepler GPUs.
First, since cuda 5.0 we have a rotated function inside of the ptx (parallel asm), we must not add this by hand because the compiler find it automaticly.

Example: (((x ) >> bits) | (x << (32 - bits))) is compiled to ptx command shf.l.wrap.b32

Note: The changes are not comatible with the opencl version, I only change the cuda source. In CMAKEList.txt is hard coded that sm_35 (Kepler code) is created.

Run new code with this parameter: -gpu=0  -aggression=8 -gpugrid=2048 -gputhreads=256

To install the patch in your code goto root of the project and run $  patch -p1 < patch.txt

Now you get over 300MHash/s out of a Kepler GPU, I think that GTX Kepler GPUs are faster than K20 HPC version. It can be that you must use sm_30 for GTX Kepler GPUs.

[EDIT:] for 330MHash/s the GPU needs 138 Watt power.

Nice find, so NVidia finally has a rotate instruction

Bitcoin Core developer [PGP]  Tips: 1L125pF2e7himW43Qu752ZFLtBLicxQmng Warning: For most, coin loss is a larger risk than coin theft. A disk can die any time. Regularly back up your wallet through FileBackup Wallet to an external storage or the (encrypted!) cloud. Use a separate offline wallet for storing larger amounts.

Wow, can you imagine if this were distributed a year ago? 

Now I just have to figure out if I can run this inside 50miner, or if I have to use cgminer...

@relm9: No I have winows version, I only programm linux. I exit my bitcoin winter sleep to performe the NVIDIA GPU bitcoin mining process. I have now windows PC with K20 or Titan and therefore I can't test this with a winows miner.

@philips: Thanks for the last link, I look in if I can get some more performance.

Not all performance came from the shift function. Most performance came from reducing registers per thread.

Before I start one threads needed 114 32Bit register (134 MHash/s)
After change the code thus we use shift operation we needed 95 32Bit register (~200MHash/s)
And after add shared memory we only need 46 registers. That means we can run 5 Block with 256 threads per streaming multiprocessor and we get 330 MHash/s.

At the moment I work on a version with over 400 MHash/s but I have some problems that the mining pool not count all my solutions.

If I have time I look if I can create a windows version.

Based on that, do you believe your changes should provide benefit to all nVidia hardware, not just Kepler-based boards?

True, but this is pretty big for people who already own Nvidia cards and can now mine more efficiently with them.

The shift functions are only available on Kepler based GPU's, -but- the other optimizations he has worked in there could give non-Kepler based cards the ~200Mhash performance.

I'd love to test this on my rig but I don't know if it would be ever possible since it has an onboard GeForce 8200 that used to give ~20Mh/s, but never been able to use or even see it after plugging an ATI Radeon 5550.

Would it be any way I could "see" this device listed on lspci and have it working to mine with this patch?

Bas news!!!

With K20 we can only get theoreticly 372 MHash/s.

We can run 120 bitshifts and 160 xor,and,add,rotate per clockcycle and multiprocessor. The asm code inside of the loop has 3725 and,or,.. and 162 bitshifts. K20 has 705 MHz and 13 multiprocessors. 705*13/(3725/160+162/120)=372

With GTX Titen we can get 475 MHash/s (theoreticly) because clock rate is 837 MHz and we have 14 multiprocessors.

All this calculations are without the caculation overhead before the loop and I am not really shure if 160 or 120 rotates can caculated per clock. At the moment I only get out real 330 MHash/s :-(
Keep in mind that this optimization not get a factor of two with old gpus, only with sm_35 (new Kepler GPUs)

Finally CUDA is getting a bit more attention from developers.

I am currently doing similar optimization work for the scrypt hashing used in Litecoin. About doubled the performance I am getting from most of my cards compared to OpenCL miners. This still sucks big time when compared to ATI cards, but it sucks a bit less than before.

With the scrypt hashing it appears much more difficult to lower the kernel's register count, as the required Salsa20/8 rounds are fairly complex beasts, also the memory-hard part of the algorithm really bangs on the memory controller.

Watch out for potential Windows binary releases in the next days. I will post into the alt cryptocurrency forum.

Please wait and save your BTC, if I have time I add this code in a windows miner which supports CUDA and is still in maintenance. Keep in mind that the source code is open source and you must give out the source for free.
Knows everyone a Windows CUDA Miner? I am out of bitcoin mining since 2 years.

I created a build solution for VS2010. Pre-built binary in bin.

https://github.com/cdmackie/rpcminer-mod

Included both OpenCL and CUDA, but I can't check CUDA.

Appreciate if someone could test it out and see if it works the same.

That's the Microsoft runtime, but it was linked to the debug version so I've changed it to a release version.

You can download again and I've added the missing file in case you don't have the runtime installed.

edit: CUDA module isn't compiled...working on it.

edit2: I've added the CUDA ptx file, so you can download the latest binaries.

For for expediency, I've thrown in a "buildcuda.bat" in the root that will compile the ptx and put it in bin.

I'll tidy it all up tomorrow (or later today as they say).

Did you use the master or kepler branch?
Does the file bitcoinminercuda.ptx exist in the same directory as the exe?
Can you try compiling the ptx yourself (run buildcuda)?

For GTX690 you must compile with sm_20. I work on a version which shuld be run better on Fermi GPUs and I have get the register count down from 63 to 34 but without any speedup :-(.

@charliemaggot: Thanks for building Win version.

Anytime. I just compiled it. Kudos for your coding it.

So for 209 errors, change buildcuda.bat

  -gencode=arch=compute_35,code=\"sm_35,compute_35\"

to

  -gencode=arch=compute_20,code=\"sm_20,compute_20\"

and run it. If you don't have VS2010, I can build it and throw it up.

Grab https://github.com/cdmackie/rpcminer-mod/blob/kepler/bin/bitcoinminercuda.20.ptx and rename it removing the ".20", replacing the other ptx file. Let me know how you get on.

About the same hashrate on aggression=10 as guiminer on a GTX 650 Ti, 50-ish MH/s.

I'm not too familiar with the other settings (gpugrid and gputhreads) so I'm not sure if those would raise the hash rate a significant amount,

That's OpenCl, not cuda, in case you are running the wrong one. Otherwise can you check you have copied the bitcoinmineropencl.cl from the src\opencl directory into where you are trying to run the exe.

Nvcc : fatal error : Cannot find compiler 'cl.exe' in PATH


Means that it can't find the C compiler. You need to have the Microsoft C compiler installed (e.g. Visual Studio 10 or Visual Studio 10 Express) to be able to build the cuda files. If you do have it already, you just need to run "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\vcvars32.bat" first in the command window to set up the paths.

If you don't have it, either download and install the Express version or just copy down the the prebuilt .ptx files from the bin directory in https://github.com/cdmackie/rpcminer-mod/tree/kepler/bin. There are now different ones, so try the bitcoinminercuda.ptx first. If that works, rename bitcoinminercuda.20.ptx to bitcoinminercuda.ptx and try again. Likewise with bitcoinminercuda.30.ptx. USe the last one that worked.

Nice work. the 20 file got it going and look at the results, 19Ghash from Nvidia cards! Shocked (30 file returned 209 error)



It's working but BTC is showing work as dupes. Not surprisingly...

GUIMiner ends up reporting as having connection issues fwiw.

I've got it working now, with CUDA I get 100-110mhash/s on a 670GTX FTW(Overclocked), with an i7 CPU

Using OpenCL I get approximately the same range, but even as high as 120-130mhash/s sometimes.

Not expecting to become a bitcoin millionaire with a 670GTX lol, just doing this for fun. However whatever improvements got added do not appear to be assisting with my machine.

Curious though what is the difference between the bitcoinminercuda.20/30 files? I am wondering if there is something I need to compile myself here.

No luck with a 660ti on Windows with any of the .ptx files.  20 and 30 load but the binary crashes after the Target and Done allocating CUDA resource messages.  (rpcminer-mod-cuda.exe has stopped working).

Tried with 314.22 and the CUDA 5.0 dev driver default (306.xx I think?).

Can provide more info if needed.

Thanks.

i will try to make an workaround to it

Might as well jump in ....First..no linuix ...just a point click, old guy in Win 7.

I have 2 - 580 GTX. Using CGminer I get 160-200 Mhash PER card . (depends on overclock and using Comp or not)

Trying this..@ first i had the "Unable to load CUDA module: 209" error. I grabbed the other .plx file bitcoinminercuda.20.ptx. Renamed it and...

Now i am getting "curl return Value = 7"

Kinda getting lost here...lol These are some of the Command lines tried....

rpcminer-mod-cuda.exe -aggression=8 -gpugrid=64 -gputhreads=384 -o - url=http://stratum.bitcoin.cz:3333 -user=####### -password=#####
rpcminer-mod-cuda.exe -aggression=8 -gpugrid=256 -gputhreads=512 - url=http://stratum.bitcoin.cz:3333 -user=###### -password=#####

rpcminer-mod-cuda.exe -url=http://localhost:8332 -user=##### -password=#### <<(set according to Bitcoin.conf)

"curl return Value = 7"

Thanks for all the hard work you guys do, would really like to get these cards working better (they are embarrassed to announce their terrible Hash rates to all the other cards on my network. Especially the 7970 getting 720 Mhash...lol).

Please use a pool with getwork support, there is no real strtum support inside the miner.

Today night (german time) I post a new reposetory with my new code. I hope charliemaggot create a windows version.
The new code supports all old GPU (I think till GTX9800). The is no ptx needed.

I think on old GPU we can't get a good speedup because the GPUs has very slow bit operations.

GPU Overview:

C1070 - old GPU - 30 Streaming Multiprocessors (SM) - ~53MHash/s
C2050 - old Fermi - 14 SM - ~ 90MHash/s
K20c - new Kepler - 13 SM - ~ 325MHash/s

@GimpyPrime The default bitcoinminercuda.ptx file was built to "compute 3.5", which was just from the patch in psychocoder's first post in this thread. It is the latest optimised level for NVIDIA Telsa K20 cards. You need to know the compute level for your card (https://developer.nvidia.com/cuda-gpus) and use the appropriate file. Your GTX 670 should be compute level 3.0, so you would need the .30 file.

You can obviously build them yourself, I was just trying to include as much as possible so it could just be downloaded and run, however I didn't include a note about which file was needed. If you have VS 2010 you can edit the buildcuda.bat file and change the compute number to be appropriate for your card - and change the compiler value if you are using VS2012.

@dentldir Should work with the 30 file on your 660. Latest stable driver? Maybe try again after I rebuild it from psychocoder's latest changes.

@camaro69327 Your card is a 2.0 Fermi device, so not sure you would see much benefit from the Kepler (3.0) optimisation in this thread. Wait and see if psychocoder can create some better optimisations. The app is still using the getwork api, so you need to use http://api.bitcoin.cz:8332 or download their stratum proxy.

@psychocoder I'll start building it for Windows once you get changes done, if you could let me know where they are. Thanks.

Thanks for the responses guys. I did get this working as i had the wrong port for localhost. 9332 Worked. Only could get one card hashing. Could get 160 easy. 214 was another common Mhash.

300 + Mh but only for 3 or 4 shares then 0.

Back to Cgminer and a steady 170 - 200 for now. I thought this was the Gen i had. Fermi not Kelper Duh.

I have checked in my code to https://github.com/psychocoder-germany/rpcminer-mod. The code is a little bit slower than my first patch. I have put same calculations to cpu to save registers.
Now I only need 32 Register for Fermi and have 100% occupancy. There is no need to create ptx because all versions are inside the binary after compiling.

Sry that I create a new repo but it was my first git commit. I am oldschool and normaly use svn^^

@charliemaggot: Please add windows compile support.

OK, switched back to faster kernel.

GPU Overview update:

C1070 - old GPU - 30 Streaming Multiprocessors (SM) - ~46MHash/s (slows down with the last patched kernel)
C2050 - old Fermi - 14 SM - ~ 107MHash/s
K20c - new Kepler - 13 SM - ~ 325M - 350 Hash/s   (options: -aggression=11)

Note: the option -gputhreads change nothing, all kernel are build to run 256 threads.

what exactly is K20c ? just so we know here.. and what gpu are you using right now, I cant wait to see 300+ on my 680 ...

K20c is http://www.techpowerup.com/gpudb/564/NVIDIA_Tesla_K20c.html a high performance GPU card. This cards are created to run math calculations with floating point operations. It is nothing for a home pc. The version for the home pc with the same architecture is GTX Titan http://www.techpowerup.com/gpudb/1996/.html

GTX680 has not the new bit rotate (funnel) operator I think 300+ is not possible.
Theorethic calculation: 1006*8/(3733/160+1194/32)=132 MHash/s   (magic numbers are the count of operations from the binary for this implementation)

IMO the GTX680 GPU is limited to max 132 MHash/s

I have updated the Windows build with psychocoder's changes:

https://github.com/cdmackie/rpcminer-mod (use the master branch)

We'll merge them together shortly.

To just run, you only need the bin folder, and run the rpcminer-mod-cuda.exe. There is no need for the ptx files anymore.

To build yourself, you need MSVC 2010 and the CUDA SDK 5.x.

Please post any errors or successes.

Er..odd. Nothing changed since last version working from yesterday?

Can you download Dependency Walker from http://www.dependencywalker.com/ (the x86 version) and run it and open the rpcminer-mod-cuda.exe file and see if you get any errors. An error is typically a file shown in red in the top left tree.

HI,

I have testet the windows version on Windows7 64.

I start the program and the cudart32_50.dll or cudart64_50.dll was mist. I install cuda for windows https://developer.nvidia.com/cuda-downloads and than all run.
It can be that this is a sideeffect from switching to runtime library of cuda.

If an error shows that bitconminer.cpp:174 crash that the parameter -gpugrid to 256 or 512, it came from windows intern limit that no calculation on gpu can run longer than 4 sec.

With GT555M I get:

22.3 - 22.6 MHash/s with OpenCL
22.3 - 22.9 MHash/s with CUDA

I put allw links to reposetories and Errors to the top post.

@InqBit Just seems like the file is corrupted. Does it match the one on gibhub? Can you try downloading it again? You will need to 32bit CUDA SDK, or at least cudart32_50.dll if that isn't included in the 64bit version. I hadn't built 64bit, as there were 3rd party dependencies, but I might try and them them later.

@psychocoder Seems there are some other ways around the time-out issue:

1) As you say, change grid values
2) Unplug the monitor from the card... assuming you aren't using it Smiley
3) Change registry settings to increase the time-out. See http://msdn.microsoft.com/en-us/library/windows/hardware/ff569918(v=vs.85).aspx. Perhaps only for the hardcore and if it's going to make a significant difference.

Were the 22.3-22.9 values you got on your GT555M in Windows what you expected? Is it the same as Unix?

Can't test it under linux. Thats a Laptop with 2 GPUs it was not possible to run the miner under linux :-(

I hope we get some results from a user with a GTX Titan.

Ok, whilst building a debug version to try and track your issue down, I found out that there is an error in the error handler. So based on the line you had the error, it's that the CUDA device driver didn't initialise properly. Do you have the right and latest drivers?

I've fixed the error handler and uploaded a new binary so you should see a more meaningful message.

any chance to include the dll?

I'm trying out the windows version with a GTX 670 and it doesn't seem to be working

I can confirm that I've installed CUDA dev software 5.0
I also have updated drivers including cudart32_50_35.dll

When clicking on the rpcminer-mod-cuda.exe file the black cmd screen comes up and an error window immediately says "rpcminer-mod-cuda.exe has stopped working"

On the cmd window in the background it says

Client will start 1 miner threads
Work will be refreshed every 4000 ms
1 GPU CUDA device(s) found
<srcudbitcoinmindercuda.cpp>:54[CUDA] Error: invalid device ordinal
Error:invalid device ordinal

When I run the debugger it tells me there is a Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call.  This is usually the result of calling a function declared with one calling convention with a function pointer declared with a different calling convention

To be honest I wasn't sure where exactly to extract the zip files, or how to make a file that alters how the executable runs...  Any help will be greatly appreciated.  Post your address and I'll tip you my first bitcent or so

I've added the cudart32_50_35.dll to the binaries so it can be downloaded, although you've probably got it by now.

I think there is a bug if you don't specify the gpu flag, e.g. using "-gpu" and not something like "-gpu=0". So can you try explicitly setting it 0, 1 or whatever.

If you still get an error, there should be a rpcminer.dmp file created in the same folder. Can you send it to me, charlie (at) legmail.com

I sent you my rpcminer.dmp file from most recent attempt.

Trying to set the -gpu flag made no difference. The video driver stops responding if that helps.

Mh, the selection of your device crash. I add later some more output which device is selected. In most cases there is a problem with the driver.

I'm seeing the same results, yesterdays build I was able to run, today with the changes.. aka required cudart and then when having it provides the same output..

Did you try the latest?...from about 3hrs ago, as there was a bug fix if no gpu parameter was specified.

I have deinstalled my cuda and run it under windows withe the dll from the repo. All worked fine.

Can you please post the commandline which you use to start the miner and all output from the miner.

@charliemaggot

I have updated bitcoinminer.cpp in my repo. I disable the hard crash if a error came out of the device selection. Normaly if no cudaSetDevice is called the driver select the first device. I have not tested the code because I do the changes in my webbrowser, but I think it compile^^

I did a full repull of the files from charlie's github and it is working now, using only 1 of my 2 gpu's. I did uninstall the CUDA dev prog as well after seeing you did, and pulled the correct file it needed from github.

As of now, not seeing any difference in hash rate on a Fermi card, but I assume that's what was expected.

I've just added the 64-bit build, in a separate branch https://github.com/cdmackie/rpcminer-mod/tree/x64.

Grab the whole repo (or just bin) and run it from within bin as before.

I don't imagine you'll see much difference, but if anyone could try it out so I can make it the default.

Now must sleep...

@InqBit: is 137694 khash/s the first shown hash rate? Please run the miner 5 min and than look to the hash rate. The first hash rate is always lower because the first kernel call takes very long.
I see you run the code with without -aggression, please add -aggression=8  or 7 to you parameter to get more performance. -gputhreads is not needed because it is ignored and hard set to 256.

theoretic calculation rate for GTX480: 1401*15/(3733/32+1194/16)=109 MHash/s   (magic numbers are the count of operations from the binary for this implementation)

Mhh in my theoretic calculation  I assumed 109 MHash/s for a GTX480. I think I must check if my operation count for fermi is right.
Can someone with a GTX480 run the code under linux without -gpugrid.

I just made the appropriate changes and started a new run. Will let you know in a few how it works out.

FWIW, I've been running ~140-145'ish on cgminer, overclocked to 800 core (700 stock). This is my general use machine, so I didn't have aggression set to keep desktop usable, but will run at 7 for testing for you. I just checked my average hashrate on cgwatcher, and it is 140.1.

I've got a GTX 670 and 50miner (via poclbm or cgminer) gives me about 92 mH/s. I'm wanting to see what this does

I'm going to ask a real noob question here, but where do I extract the 7zip files to?  Clicking on the .exe from the bin just causes it immediately open and then stop working, and I can't input any parameters.

You don't need to extract 7z files unless you are compiling it yourself in Visual Studio.

Otherwise you just run it from the bin folder:

e.g.

rpcminer-mod-cuda.exe -url=http://<yourpool>:<poolport> -user=<username> -password=<password> -gpu=0 -gputhreads=256 -aggression=8

where
<yourpool> is your pool address, e.g. 127.0.0.1 if mining solo or something like api.bitcoin.cz
<poolport> is your pool's port, normally 8332
<username> is your pool login
<password> .. you guessed it

If you get an error whilst it's running, it may because the GPU processing is taking too long and by default Windows thinks the GPU has crashed after 5 seconds. So try reducing aggression, or add "-gpugrid=256" or "-gpugrid=512".

If you are still getting problems, can you include the error text you get.

I think the general crashing is just because the code is throwing an exception when it sees an error. I'll change it to exit nicely.

btw when I exit the app it kills my display driver..

What exactly are you seeing here? I've only got an Amazon EC2 instance to test on, and I don't get an issue. You're Ctrl-C-ing?

800 core, instead of 700. Pretty modest OC. Could probably go higher, but this is my main machine & don't want to risk blowing it up...

I really appreciate you guys being so patient with me.  But where exactly do I even input these commands?  I do know how to make a batch file, I go to notepad, type the commands I want and save it as a .bat, drag the file in the folder and try to run it, but this doesn't seem to work.

Okay! I actually got it to work properly.  I created a batch file in the same folder and this time actually included the words rpcminer-mod-cuda.exe at the beginning haha  Smiley I know this is pretty typical stuff for you guys but this is one of the first times I've had to deal with batch files.

Initially it crashed, then I added the command -gpugrid 512 and it worked properly. 
all the arguments I'm using are -gpu=0 -gputhreads=256 -aggression=8 -gpugrid=512

Normally, with a basic 50miner program my nvidia GTX 670 will max out at 92-93 mH/s, but now it seems to be pushing 96+ mh/s.  I'm going to continue to tinker and see if I can push it higher.

Go to https://github.com/cdmackie/rpcminer-mod

and either use git and checkout the repository, or just click the "Zip" button at the top to download it.

To run, you only need the files from the "bin" directory, so extract the whole thing or just that.

Open a command prompt, go into that bin directory, and run the command line:

rpcminer-mod-cuda.exe -url=http://<pool>:<port> -user=<username> -password=<password> -gpu -aggression=8

where <pool> and <port> are your pool server, e.g. api.bitcoin.cz:8332, and obviously <username> and <password>

If you get an error whilst it's running, it may be because the GPU processing is taking too long and by default Windows thinks the GPU has crashed after 5 seconds.

So try:
1) reducing aggression
2) add "-gpugrid=256" or "-gpugrid=512" (see which works and is best)
3) unplug the monitor from the card (if appropriate)
4) adjust the Windows GPU timeout settings (http://msdn.microsoft.com/en-us/library/windows/hardware/ff569918(v=vs.85).aspx), e.g. TdrDelay to 20 and TdrDdiDelay to 60.

Once its working, you can increase aggression and/or gpugrid to get best settings.

Just tested the program mining solo with my GTS 450 (core and shaders overclocked to 950 MHz/1900 MHz, 1 GB GDDR5 memory underclocked to 900 MHz) on Windows XP 64 and it ran with no problems. I used this command line:

rpcminer-mod-cuda.exe -url=http://127.0.0.1 -user=XXX -password=XXX -gpu -aggression=1 -gpugrid=1024

Got ~48 MHash/s with those settings. I already had CUDA SDK 5.0 installed (both the 32-bit and the 64-bit versions). Only needed to download rpcminer-mod-cuda.exe, libeay32.dll and ssleay32.dll.

EVGA Precision showed the card was using 99% of the GPU (that program only goes as high as 99% if I'm not mistaken), but the desktop was absolutely smooth as if nothing else was using the GPU.

Tried -aggression=5 but that only increased the hash rate by ~0.5 MHash/s and the desktop got laggy (but still usable), so I don't think that's worth it in my case. Same thing with -gpugrid - could increase it up to 4096 before the desktop started lagging a little. Hash rate with -gpugrid=4096 increased by ~1 MHash/s only.

@Ephebus :

You get better performance if you set -aggression= to a bigger value and -gpugrid also to bigger value. But than you desktop is not smooth. Do you tested also a other miner?

Yes, I was editing the post with my experiments with -gpugrid when you posted. Wink I could get it up to 4096 before the desktop started lagging a little for an increase of ~1 MHash/s. Not worth it in my case, but will probably make a much bigger difference with more powerful cards.

Also, lowering -gpugrid to 256 the hash rate only dropped to ~47 MHashes/s and I could play encoded XviD and X264 content smoothly at full screen, and was even able to join my Wolfenstein: Enemy Territory server and play with my normal maximum settings at 1680x1050 and 125 FPS without a hitch. Hash rate dropped to ~25 MHash/s while playing though.

With poclbm I can reach ~39 MHash/s at those clock settings but at the expense of an extremely laggy desktop. I never use the normal rpcminer-cuda because it almost freezes my desktop no matter what settings I use and always yields lower hash rates than poclbm. Conclusion: rpcminer-mod-cuda increased my hash rate by over 20% while keeping a completely smooth desktop and even allowed me to play my favorite game while still keeping a good enough hash rate for the GTS 450.

So the thread says going from 134 - 330.. I have yet to see any sort of leap from using other miners or rpcminer at default.  I realize that people are working on functions to try to improve that and their efforts are greatly appreciated but, I think all of us would like to see a nice bump in our mining with our nvidia cards.

thoughts?

134 MHash/s to 330 MHash/s is for a Kepler K20 or the consumer version Titan. A big jump with old NVIDIA GPUs is not possible. CGMIner is very near to the maximum power of old NVIDIA GPUs. Al GPUs before Titan has no funnel opertor and need 3 operation for a rotate, the new one need one operation.

Ahh ok sorry my bad, thanks for the clarification.. so your saying the 690's and below will still be somewhat limited or same speed with out much boost?

Onyl Kepler equal or higher than titan GPUs. GTX680 is K10 architecture, you can say it is a better fermi. K10 has no funnel operator :-(. Thay have the same amount of 32Bit registers and a lot of opration have the same speed  than a k20 but the importend operations are not available.

So did this thread ever amount to anything? Will I ever see a "significant" mhash from my gtx 680? I use win7 x64. Linux not an option for me. I tried "-gpu=0  -aggression=8 -gpugrid=2048 -gputhreads=256" but I only got 112 mhash.

134 MHash/s to 330 MHash/s is for a Kepler K20 or the consumer version Titan. A big jump with old NVIDIA GPUs is not possible. CGMIner is very near to the maximum power of old NVIDIA GPUs. Al GPUs before Titan has no funnel opertor and need 3 operation for a rotate, the new one need one operation.

Ahh ok sorry my bad, thanks for the clarification.. so your saying the 690's and below will still be somewhat limited or same speed with out much boost?

I have a gtx 680..

GTX 680 IS a Kepler..

Onyl Kepler equal or higher than titan GPUs. GTX680 is K10 architecture, you can say it is a better fermi. K10 has no funnel operator :-(. Thay have the same amount of 32Bit registers and a lot of opration have the same speed  than a k20 but the importend operations are not available.

I am waiting for the 700 GPUs to come out, or get a deal on another titan.


Psycho So none of the Kepler Base Quadros can do this either?

I am poor, but i do work for Coin Smiley

I think so, but I think there is no Quadro out with K20 architecture. At the moment the GTX Titan is also to expensive to buy.

Hi charliemaggot !

I have nv670 - 100 m.hash/sec with GUIminer.

If i run rpcminer-mod-cuda.exe with GUIminer i get:

Faulting application name: rpcminer-mod-cuda.exe, version: 0.0.0.0, time stamp: 0x5163a5d3
Faulting module name: MSVCR100.dll, version: 10.0.40219.325, time stamp: 0x4df2bcac
Exception code: 0x40000015
Faulting application path: D:\bitcoin\miner\guiminer\miners\puddinpop\bk\rpcminer-mod-cuda.exe
Faulting module path: D:\bitcoin\miner\guiminer\miners\puddinpop\MSVCR100.dll
Report Id: b1683d16-a64f-11e2-b5bb-5404a61bb659

Display driver nvlddmkm stopped responding and has successfully recovered.



With command line i get:

"Could not retrieve work from RPC server.
CURL return value = 22"

I set TdrDelay and TdrDdiDelay = 10,60.

Can you help me to run rpcminer-mod-cuda.exe ?

@slon_ru can you post the manual command line (hide your username/password) that causes the crash, and the output you are getting.

CURL error 22 is a HTTP error from the server, is your pool working ok?

If you reduce -gpugrid down to 256 or 512, do you still get the error?

Lastly, please try downloading and running the files from the debug branch, which will hopefully give more information on the crash:

https://github.com/cdmackie/rpcminer-mod/tree/Debug/bin

Again, post any errors.

I can't even get it to run. I get unable to load cuda module error. When I try compile the module myself per the instructions...I get this error:

So Kepler does have a bit rotate instruction. Finally, Nvidia!

Does it have the equivalent of AMD's bfi_int for another speedup? It does not seem so.

This is a mismatch between the runtime libraries, I guess the project has an error. Make sure you are building a Release/x64 build. In the meantime, can you download the Debug branch from https://github.com/cdmackie/rpcminer-mod/tree/Debug/bin and see if you get the same problems, and post any output.

Can you please add the full name of your grafic card! Our post a link to the shop and product were you have board the gpu. I think there is no GTX Titan with 1150 mhz. I my theoretic calculation a GTX Titan with 1150mHz must get 500+ MHash/s. Please post the first 20 lines output from rpcminer thats help me to see why you Hashrate is so low.

And yes the paramater -gputhreads=x is disabled because the kernel are compiled for 256 threads only.

I saw you mention 560 Ti earlier. That's my card. What hash rate did you see before/after this mod? I'm getting 80-90 mh/s now using GUIMiner w/ rpcminer-cuda.exe but would welcome any additional boost if possible.

If this is about the best I can do with current card, I will likely do a new build + move to Litecoin soon.

The pre-built binary is 64-bit, for 32-bit you can either build it yourself or download the last pre-built binary files from:

You are probably trying to use the stratum protocol. Use a local stratum proxy or switch to the getwork protocol if they support it.

Otherwise, post the command you are using.

I'm used to just unzipping files into directories, then clicking on the appropriate executable file and away I go, like how cbuchner1's CUDAminer app works.

Thanks! Ok, just tried running it and I got the following error message:

C:\Mining\RPCMIN~1\RPCMIN~2\bin\win32\RPCMIN~1.EXE
The NTVDM CPU has encountered an illegal instruction.
CS:0e4b IP:0528 OP:63 6f 6e 74 65 Choose 'Close' to terminate the application

I'm running a GT 220M, so that could be an issue. If it also helps, it uses Compute Capability 1.1. Would be nice if I could just take the relevant code from cbuchner1's program and adapt it to something like CGminer, which I know normally works fine with my laptop, but my C++ programming skills are too basic at the moment to be able to do that.

I've been able to get up to about 190MH/s out of a normal GTX 680 but its still really not worth it.  You can get double that for a card half the price.

I just tried this on c2075. The result agrees well with the c2050 card (107mH/s). There is fluctuation (from 70 to 140).

Code:
rpcminer-mod-cuda.exe -url=http

can anyone list a rpc mining settings and overclocking settings for each nvidia cards starting to 600series? it might be very helpful to others who wants to maximize the potential hashing power rate of the nvidia cards.  Grin btw im using 660 ti

I am using this to mine PPCoin on coinotron. The setup is the same as in my post #195 . There were 144  this
Code:
Found nonce 3FD7CA5E
2013-05-05 13:54:53 Found Hash!
within a period of 100 minutes. But coinotron only reported 19 shares. What is really strange is that the average kh/s reported by coinotron agrees with the hashrate printed by the miner on average. That means the rate at which my miner finds shares seen by the pool is correct, but the "Found Hash! " is 7-8 times too often. Why is that?

EDIT: earlier port #

I just tried this on c2075. The result agrees well with the c2050 card (107mH/s). There is fluctuation (from 70 to 140).

The fluctuation come from you "slow" card. The summery is build every 30 sec. It can be that some times the count goes to the next or previous intervall. A drop is also possible if you get no connection to the getwork server. The best is to use the http://mining.bitcoin.cz/mining-proxy-howto stratun proxy. If you use them you get better and smoother results.

I have never test the miner with PPCoin. It looks like many rejected hashes.

High rejection rate can't exlpain why the hash rate seen by the pool agrees very well with the rate what miner prints out.

Any way to have a log file saved to computer much like cgminer can? If so , what is the command please.


Thanks.

Hello guys!
I was wondering what kind of parameters I have to set up to optimize the miner for my GPU...
It's a 660ti (GK104) and the current parameters are "-gpu -aggression=13 -gpugrid=128 -gputhreads=512".
Unfortunately the GPU is only running at around 60% power, reaching around 95-98MH/s.
With cudaminer (scrypt, I know) I was able to get nearly 180kH/s with 100% power usage.

Could anyone please help me out...?

who runs a mining help group or site? that could be profitable
