Topic: [ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX] - page 754. (Read 3426976 times)

I did a small check on the high N optimization (however I didn't run on yac since quite some time).
I also stopped the autotune at the 17th line (it really take a long long time...).
The hashrate on this test has increased until -L12 and yields to 4.7khah/s on windows (didn't tried linux, I assume the real gain should be on linux). Running on a pool (one share every 5 minutes... now I remember why I gave up on yac) this gave me around 4.5khash/s.
But as I said I didn't perform the autotune on the full table, so there could be better value...

On MRC, it gives me around 5~10 more khash/s (at L2)

T14x24 launches and hashes around 7-8 kh/s on each card for a few seconds...then I get the same launch error on GPU #3

Should I try to go back to the December version? Am I missing a prerequisite software to make this work with the latest version?

Why? I hit "build" and it's done ;-)

Gonna try it tonight... 

"launch timed out" is unusual for autotuning an scrypt coin.

use -l T14x24 instead of -l T14x32. This should fit your cards.

the problem arose when you updated your cudaminer release from a December 2013 to a February 2014 release. Kernels were swapped out (nVidia's submission proved to be a bit faster than David Andersen's kernels).

On T kernel you cannot go higher than x24, so x32 won't validate and now you need to reboot to reset the card

Here's the result when I use autotune...

[2014-02-27 15:57:33] GPU #3: cudaError 6 (the launch timed out and was terminat
ed) calling 'cudaDeviceSynchronize()' (D:/Christian/Documents/Visual Studio 2010
/Projects/CudaMiner/salsa_kernel.cu line 644)

Page 130 still works

Compiling windows binaries is SO complicated
I wanna try the new nvidia n factor 14 kernel.

Well most of us ,when chrome opened and running flash game for example, have a boost of 20-30khs.

A little bit of reading the output can not hurt, it's there for a reason, basically your specified numbers are too high, try autotune

I am running it and if anything I think I am down about 5 kHash each card... Need to do anything special, or just have it open?

Hi Guys! I need your help to fix my rig.

Just did a format-clean-re-install of windows 8.1 and cudaminer won't hash now properly. Any insight how to fix this would be much appreciated!

System Specs:
Windows 8.1
Nvidia driver 334.89
1 Quadro 4000 slot 1 on Supermicro chassis
4 GTX Titans GPUs in Cubix Xpander Desktop Elite (I'm trying to hash with just the Titan's)
Supermicro 7047grTFT
2 x E5-2660 XEON CPUs
128 GB system ram

Each of the algorithms runs separate difficulties & miners, so it's as if it was not 1 coin, but 5 different coins all sharing the same rewards.
In other words, you'd need to add cuda support for 'groestl' only, and we'd have the 1st & only gpu miner for that algorithm.

On a completely unrelated topic: do your 'pals' over at nvidia give you any hints on launch dates for the high end 800 series? I'm greatly impressed by the 750's & 750 TI's, can't wait for the high performance (and super efficient) siblings to come about.

Thanks for the feedback though! Cheers!

christian is it basic --algo=keccak i want to run for helixcoin?

im not sure if keccak has N factors?? yehhh can tell i havent been very active lately

Run it and you will see   a booost..

No I do not have Chrome running, does it cause slowdowns?

Thanks, I'll fix those settings. No it does not crash, and it really seems to have little to no impact on my hash rate. Using Precision-X and I see the frequencies go up, but the hash rates seem to stay consistent at 280 kHash even when going to +100 on core and +500 on memory.

Helix
i will use my maxcoin launch config, but need to change some things to suit the coin i believe?

cudaminer.exe --algo=keccak -d gtx780  -i 0 -m 1 -l K2304x32 -L 1024 -o 127.0.0.1 -O user:pass -D

for anyone wondering why helix coin is being talked about. its a pokemon based coin, for anyone that didnt know, twitch is having huge issues right now due to pokemon tournaments causing huge server load i believe it is?

anyone with a good .bat for microcoin for gtx 780 3GD? I used to mine with 400 each card but after the N factor went up i get less than 100 with both cards...

EDIT with autotune I get around 185 with each...
