NVIDIA Kepler (K20) from 134MHash/s to 330MHash/s with CUDA

[charliemaggot]

i have win8 and geforce710m on my laptotp

can someone give me the instructions for make it?

Start here, https://github.com/cdmackie/rpcminer-mod

Feel free to ask if you have any questions.

[jeprokzki]

thanks sir it's working now but my computer gets really slow it is normal? my old hashrate is 101.5mh/s but now it's 179mh/s im using gtx 660ti oc ed.

Is its right that you now faster than before? 101->179 MHash/s
With which program you get 101 MHash/s, is it up to date?

cgminer v.2,11,4 sir

Once I start it I get this, any suggestions?

Getting around 99 Mhash/s while I get around 104 Mhash/s with CGMiner

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?

I have a gtx 680..

GTX 680 IS a Kepler..

[gateway]

So the max I have been able to push my 680 with out oc , is between 120-130.. mostly lows 120's.  I would love to even add 100 more but its not my main mining rig just add's to my pool from my other cards..

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.

[ssateneth]

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.

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 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 ?

br

[Amph]

nothing changed, still 100mh with my 670

[charliemaggot]

@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.

[slon_ru]

@charliemaggot Thx!
It was my fault, i wrote without "-password",i have no pass.

Now i have 90 m.hash/s with rpcminer-mod-cuda.

br.

It seems that no additional hashrate for GTX 580 here.

[Lacan82]

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:

LIBCMT.lib(crt0.obj) : error LNK2019: unresolved external symbol _main reference
d in function ___tmainCRTStartup
a.exe : fatal error LNK1120: 1 unresolved externals

No one can tell me how to fix it. I'm not much for a programmer..
