[ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX]

How do you turn-on the temp monitoring ? I didn't see it.

not yet committed, but I have a patch waiting that can be integrated in no time.

I am at work now, so this has to wait a little.

The strange thing is the TDP which is well below 100% while running and the gpu usage is around 97%

a TDP use below 100% is suspicious for a compute bound algorithm

does it mean we have untapped reserves in the code?  I guess I need to pick up my red telephone to my nVidia performance engineers again ;-)

Perhaps this is (once again) a PCI bandwidth issue?

I've been looking into the newly released HeavyCoin, which uses 4 well known hash functions
(SHA-256, Keccak-512, Grøestl-512, BLAKE-512) plus a new one called HEFTY1

They claim it's CPU only, which I might actually put to the test.

Just saw this...  Go get em!!

Hello, I just installed the new 335.23 driver on my windforce 3X GTX 770, and now Cudaminer is giving the following message:
'[2014-03-11 08:58:15] Unable to query CUDA driver version! Is an nVidia driver installed?'
I use the newest version of Cudaminer given, in combination with CUDA manager (version 1.2.1). If I try to run the miner outside of manager, it starts and then rapidly disappears. My set-up is as following:

Corsair Vengeance 16 GB : 2 x 8 GB
Toshiba DT01ACA100 1 TB
Kingston SSDNow V300 120 GB
Thermalright Macho Rev.A
Intel Core i7 4770K / 3.5 GHz
Asus B85-PLUS
Gigabyte GTX 770 OC Windforce 3X
Windows 7 (completely up to date)

Edit: When I use the rollback function to get back to my previous driver, the error keeps persisting.

Edit 2: Performing a clean install as we speak.

Edit 3: The clean install did not resolve the issue, I did it twice to be sure, but the problems still persists.

I got the same message.

I just rebooted the machine and all was fine.

But I take it since you did a clean install you rebooted.

I can confirm issue with risers . I bought 3 just ti fix my temperature issue , and put one card outside of the box. When on riser the card no mater waht clock makes max 295 khs with 1280 and 1350 mhz the same , and in the mobo it makes 310-315khs with this clock. Risers are usb3 ones.

[bigjme]

risers are not as fast as directly connected, so expect a drop

Yes but can it be done using code in CudaMiner? Because forcing 3D mode all the time is a waste of energy if you idle.

nice, if I can find source code to nvidia inspector I could even integrate this functionality in cudaminer.

EDIT: nope, it's not open source. I will try to contact the author about it.

I honestly couldn't tell you that. But you can set a batch file to implement it, and then run another to reset to stock. Unfortunately, I don't code, so I'm not of any help there. I was just presenting some info that I thought might be relevant. It's done with Nvidia Inspector: http://www.majorgeeks.com/files/details/nvidia_inspector.html

In case anyone is interested.

Edit: I see that Christian is already on it!

New Scrypt Jane coin launched, you might want to throw at it some of your 750 Ti. I am curious what is the speed of these cards at the N-factor of 4.

https://bitcointalk.org/index.php?topic=510353.0

The mining is pretty scarce for the first months and the dev might not seem interested to dump if they will appear on some exchange. I have thrown all my red team at it.

50% premine.... what a joke
might be interesting to check though to see how the cards handle N=4

And get them to try and fix the need for chrome lmao

so far I do not know how to achieve the same effect. Should I open a DirectX window and render a little spinning cube or what

Ah, now I know: I will have to integrate flash based advertising!

Is this trick only required for windows? If so, you could try to set the time period to 1 ms. (I believe this is what flash does).
The API is: timeBeginPeriod
What this basically does is increase the (global) interrupt time of windows, which among other things allows waiting functions to be more accurate.
Windows has a default period of 15.6 ms. Meaning every WaitForX, Sleep or Timer function has no better accuracy then that.
When 1 process in the system (e.g chrome) requests a lower time period it affects all processes running on the system.  
Hence it might be boosting CudaMiner.
So if someone who gets major benefits of having chrome open and is able to compile the software would like to test this:
Add somewhere at the top of main a call to timeBeginPeriod(1).
At the top of .c file in which main is defined add:
#include <Mmsystem.h>
#pragma comment(lib, "winmm.lib")

[69charger]

oh ya new 335.23 drivers even faster http://cryptomining-blog.com/tag/335-23-whql/

His hashrate sucks for that high of an overclock. Getting stable 330kh with a +125 +600 overclock.

I assume you are using -H 1 for this result?

Yes -H 1

[69charger]

Had to revert back to 334.89 drivers. 335.23 was causing freezes after waking up the monitor while running cudaminer. Hmmm....

oooh, this is hot info. Thanks. I would probably add it in the part of code that initializes CUDA.

same concept as Auroracoin.  Depends entirely on the honesty and capability of the devs to pull off a nation wide airdrop.

I believe more in automated airdrops implemented as a wallet feature

So would that be -a scrypt:4?
