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

[djm34]

I wanted to see how much the new version improves Yacoin performance on my 660Ti.
But I can´t seem to get it to mine at an acceptable rate.
With the older versions I was getting about 3.2kHash. (my card is highly oc´d and used only for mining)
But now i can´t seem to get near that.

Earlier I used --interactive=0 --hash-parallel=1 --launch-config=K7x23 --texture-cache=0 --single-memory=0 --lookup-gap=3
Now that same launch config doesn´t start and via autotune I only get around 1.7kHash.
I´ve tried several combinations of the other options, but nothing helps. (also batchsize doesn´t seem to change anything for me.)

BTW I want to report a small bug: --batchsize=x isn´t recognized correctly. Only -b x works.

You should try to increase even more the look-up gap value

Nevermind. Had libcurl5 installed, needed 4

 --launch-config=K7x23 should be k27x3

and it's probably --batch-size=...

My board seems ideal for this (or any X79 with 4 slots for that matter)...

Not sure if this still applies though: http://nvidia.custhelp.com/app/answers/detail/a_id/3135/session/L3RpbWUvMTM0MDIyMzU2OC9zaWQvaDEzbE45X2s=

@anyone

Hey guys I registered just to ask this... I've got 2 gigabyte 750ti's and one is kinda acting strange.. i have one OC'd @ +100 core & +500 Memory which yields me 295 kh/s roughly... But my second card keeps on crashing whether it's OC'd or not..

Should I RMA that card?  as I even tried Underclocking it and it still crashed.

The error has something to do with memory, Is it VRam or Ram? As i could always add more.. If it helps i'm on Win7 x64..

I hope someone could help as this is kind of irritating me..

Appreciate any replies, Thanks

Swap the cards in the PCI-E slots and see if the same card gives you issues.

Sounds like a busted card to me, but try it as a single card only first.

[guzzzi]

So 350/360kh/s each gtx780ti is max for this Card? All other settings i done cudaminer gets me error or not enough memory msg. or the nvidia drivers breaks.

Hi, I'm new to the forums and crypto mining in general. But I thought I'd share the performance results of some riser testing I did.

Specs:
EVGA GTX 750Ti FTW (has 6 pin power connector)
Intel G3220 on ASRock Fatil1ty Z87 Killer

Conservative overclock: +50 GPU, +500 Memory

And the results (scrypt):
Baseline (plugged straight into x16 slot): 290-299 kh/s

Non-powered x1-x16 in x1 slot: 270-280 kh/s
Powered x1-x16 in x1 slot: 272-282 kh/s
USB powered x1-x16 in x1 slot: 270-277 kh/s
USB powered x1-x16 in x16 slot (gen 1): 266-269 kh/s
USB powered x1-x16 in x16 slot (gen 2): 288-295 kh/s
USB powered x1-x16 in x16 slot (gen 3): 288-297 kh/s
Non-powered x16-x16 riser: 292-297 kh/s

As you can see, there's not much penalty for the riser as long as you're able to plug into a gen2+ x16 slot. If you're plugging into an x1 or gen1 x16 slot, there's a 10-15% performance penalty.

I hope this information proves useful.

Edit: Command line was: cudaminer.exe -H 2 -i 0 -m 1 -l T5x24 --benchmark

Just donated 1 LTC to you, keep your great work on cudaMiner.

Thank you very much! The same goes to the anonymous donor with the 2.0795371 LTC donation

Ok I tried the settings, but K27x3 only gets me "result does not validate". I have to increase lookup-gap to 9 in order for it to run, but then it only gets me around 1kHash. I´ve already tried other launch-configs (autotune) with higher lookup-gap, but the higher I go the lower my hashrate.

When autotuning on some settings, it crashes my driver. And somehow any configuration never uses a lot of ram.
For example autotune found K14x2, it works but only uses 1295MB of vram on lookup-gap 3.

EDIT: seems to be the same with the older version I was using before. (2014-02-09).
I last used scrypt-jane when the feature was in beta. (i think 2014-01-22)
With that version and my old config I now only get 0.5kHash.

Also I found out that -batchsize=x is recognized as a command (only one -). However this prevents cudaminer from starting to mine. It stops at:

swap the upper case K against a lower case k.

It's probably best to auto-tune the lower case k kernel with various lookup gap settings and pick the best one.

[djm34]

I looked a bit into bus usage (with AB), not sure if it is very helpful here what I found:

On scrypt; scrypt:2048 with H2: The bus usage is around 14%
On scrypt-jane, it is 2%
The strange thing is when using autotune (on scrypt-jane), this one is all over the place going up to 100%

Christian

Okay I didn´t know that makes a difference. Trying it out right now. Already looks better.
Thanks!

EDIT: For some reason my graphics driver crashes when autotuning with higher lookup-gaps. Not immediately, but when it´s almost done.

the crashing is due to a time-out... haven't found a way to solve it yet. Use the -D option to at least get some readings before the crash.

 Thanks for this info. I was expecting more from these cards. Did you try any higher overclocking? And how many cards did you try at one time?

[Takashi267]

I can check my 780 on pci 3 x16 if you guys want those results

That would help tremendously. What kind of risers do you have? Can you try a 16x to 16x riser or even a 1x to 16x in that PCI-E 3.0 versus the card being put into the slot directly? Thanks.

I missed the riser part sorry. Would test it but it means ripping my water cooler apart :-(

Ah, no worries. Would still be curious if 3.0 slots yield any benefit versus 2.0 slots for cudaminer if there was any way you had a means of doing that without messing up the water cooling.

While I dont have any risers laying around my motherboard has PCI-E 2.0 x16 slot running at x2 and a heavily overclocked GTX 780.
Here is my config for my GTX 780: cudaminer.exe -q -i 0 -m 0 -H 2 -l T12x24
PCI-E 3.0 x16: ~715Khash/s  with a bus usage of ~13%
PCI-E 2.0 x16(x2): ~685Khash/s with a bus usage of ~40-50% (I forgot the exact number)

If you have any more questions feel free to ask.

First post so hi everyone!!!

Just wanted to say thank you for this awesome miner!

Zotac Nvidia Geforce 670 @ 1267 Core & 3416 Memory - 375 kh/s!

cudaminer.exe -H 1 -d 0 -i 0 -m 1 -l auto -o stratum+tcp://etc.etc:etc -O pass

[heajin5921]

I wiil try my 780ti for this.
thanks
