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

[Mkilbride]

That made no sense.

cudaminer.exe -H 1 -m 1 -i 0 -l K7x32 -C 1 -o stratum+tcp://stratum-us.doge.hashfaster.com:3339 -O

Explain to me what is wrong with this config?

I tried changing the K to a Y, and lowercase k as well, but nothing.

With yesterdays version, I got validation errors.

With todays, it doesn't start at all.

With 12-18, it runs fine.

For scrypt on GTX TITAN i think this is little bit better:
-d 0 -i 0 -C 2 -m 1 -H 1 -l T14x24 (605khash/s @ 928Mhz)

I'll have to try this out, I'm fairly sure that i'm getting very similar results with my config.

No matter what combination I use, the best I can get with T12x24 for my 780 is less than 1/3 of T12x20, ~170-185kh/s depending on settings.

Confirm some things for me:

• Make sure you are using the latest Nvidia Drivers, 332.21 for full Compute 5.5 support.
• Make sure you are unzipping a fresh copy of the files, not overwriting your current folder. I had a small issue where unpacking the latest releases and overwriting the files did not work correctly and cause funky hash rates. Not sure what went wrong but worth noting.
• Let us know the model of your card.
  

I'll try out the 14x20 for myself after work tonight and see if maybe it's not a bad secondary option. I'm open to any ideas

At the least we might be able to see if we can identify why this oddness is occurring and maybe make a separate recommendation for those that don't fall under the SMX x 24 bucket as intended. At worst it might be an unknown bug, but no telling until we run everything down.

Any ideas why both GPU's can't be used at the same time?

suspected nVidia driver bug. use two cudaminer instances. It's all in the README that no one bothers to read

I am running two seperate instances
2 seperate dos windows. 2 seperate folders, 2 seperate commands d 0 and d 1

ok then I apologize. No idea what causes it, really.

Curious that I could mine vertcoin or just plain old scrypt using this miner based on what looks to be version 2014-01-20 (beta) - http://kilovolt.co.uk/Vertcoin/Cudaminer64.zip
Using the same folder and executable but launching 2 seperate dos windows works just fine.

cudaminer --algo=scrypt -d 0 -H 2 -l K8x32  -i 1
cudaminer --algo=scrypt -d 1 -H 2 -l K8x32  -i 1

Your config runs on my GTX 660Ti using cudaminer 2014-02-02 (x86) with about 313 kHash/s.
Doesn't make any sense to me either.

Does it state anything about "launch config requires too much memory" before failing?

GTX 760 speed went from 305 oc to 331 oc. Very nice! But the best part is that the temperature dropped down amazing 6-7°C. Nice job!

Any news on Cuda 6.0? You think it will boost mining speeds more than it is now?

Using 332.21:Yes. Win 8.1 x64 enterprise, 6gb ram, core i7 920 @ 4ghz
Unzipping to new folder: No difference. x86/x64 version, no difference
Card model: Gigabyte GTX 780 WF V2.0

Memory and GPU usage etcetc is the same, except that the power draw sits at around 45-50% instead of 85%+ with x20

Use small k not big K for the kernel

[Mkilbride]

Tried upper and lowercase, said it in post.

It just closes automatically, doesn't even start.

Run it from the command propt. That way it'll stay open and you can see what happened.

I have the same card and am experiencing the same issue. This is the card; http://www.gigabyte.us/products/product-page.aspx?pid=4673
I'm running the latest build (w/ hotfix). I also compiled it myself, but it has the same issue.
GeForce 334.67 beta driver, Windows 8.1 x64 Pro, 16gb ram, Core i7-3770k @ 3.5 ghz

what is this big -O at the end?

[cbuchner1]

what is this big -O at the end?

I assumed he cut his worker name and password on purpose.

If he didn't ... then it would be a noob error and the explanation for all his woes. ;-)

a pause command at the end of his BAT file would have shown that one of his
options passed was incorrect - instead of immediately closing the DOS window.

[Mkilbride]

I have a pause command.

The command prompt closes anyways.

And the -O command works with 12-18, but not the newer ones, and every config, even the ones in this thread show to use it. So explain to me.

I have never seen a more rude author of a program. Abit peeved, infact.

[zureman90]

coming from previous version, my gtx 560 ti goes down from ~168kh to ~144kh using the same settings: -H 1 -i 0 -l F8x16 -C 1

autotune is even worse (i redownloaded the hotfix!), choosing F16x13 for ~130kh

anyone else here with gtx 560 ti?

[Mkilbride]

I have just discovered the strangest thing.

if I exit the folder, then re-open the bat file, it runs, but still validation errors / low hash rate.

But if I exit the command prompt, then try to re-open, it doesn't work. But if I leave the folder again, then open it, the command prompt works again. I've never seen anything like this and it only happens with the latest version.

K7x32 does not validate
Y7x32 does not validate
Lowcaser versions don't either.

GTX670 SLI. But with 12-18, it validates @ 570KH/s. This one shows around 697KH/s, but every other one fails to validate, so there's little point.

2 EVGA 780TI reference models with Skyn3t's bios. Per the other posts on this thread, iv tried many combos of C/H/m with T at 15x24 with no luck

-C 2 -H 1 -m 1 -l T15x24 runs at 20khs no matter what C/H/m is at

Best auto was T480x1 at 620khs

This new version doesn't work so well for me

[liomojo1]

On my gtx 760 using Y6x32 i got 290khs max (microcoin), now with the k kernel with the new version i cant get more than 230 , and autotune is really slow and cant make an easy decision and stoped at k148x6. With the 18.12 version best config for K kernel was K9x32 (290khs), but now it gives me 120khs/s.  For now  my best result is with this config on prereleased cudaminer supporting Y kernel : -d 0 -i 1 -l Y6x32 -H 2 -C 0 if i put H to 1 or 0 i get half the result.
If anyone with same card have any better results please share.
Thank you for your great work . We Love you man.

[HolyHatred]

k8x32 might require more memory cudaminer can allocate (in one piece).
Does -C 0 fix it?

Otherwise try using a lookup gap. -L 2 or -L 3 ... this reduces memory requirements.

and autotune with -l k  after changing the lookup gap.

Christian

alright its working but i was hopeing i would get more of a hash rate.

currently using -a scrypt-jane:Yacoin -H 2 -d 1 -i 0 -C 0 -L 3 -l k95x1 and getting between 2.1 and 2.4khs

Any suggestions?

Hi Christian,

I missed the scenes for a few days. Now vertcoin is very profitable. VTC/BTC is almost 0.001 now.
Could you tell me some tips to configure Fermi cards for Vertcoin ?

Thanks in advance.

Try T15x16 (in script) it should work better
