Title: CUDA won't show up with GUIminer
Post by: BrosephStalin on February 07, 2013, 03:03:43 PM
So I recently started mining some with my GTX570 OC'ed to 800/1600. Being a Nvidia, the speeds arent exactly amazing and I'm at around 135Mhash/s using OpenCL.

Using the CUDA drivers would probably increase my speeds a bit, however if I try to make a new CUDA worker the device option doesn't show up. I have the latest drivers and thus should have CUDA installed, but it doesn't show.

Thanks in advance for helpful replies :) Sorry if this isn't the right forum, but then again I can only post in this sub section :)

Also, when using 1 core for CPU affinity, that core is at a constant 100%. Is this normal?

Sounds like you're CPU only. It was working before? Driver crashed?

1 core of my CPU only @ 135Mhash/s really doesn't happen. Also temps and load on GPU rise to max, so I doubt it. I have no idea why it is at 100% though.

The problem here is that I have to use OpenGL for my GTX570 and not CUDA, which should give me better performance :)

I'm not sure whether you've found the solution or not, but just in case another person comes by this post, then this will be help for them too.

For CUDA mining in GUIMiner (it uses rpcminer-cuda), it doesn't show the list for you to choose your device, instead you have to specify it in the "flags" box. Otherwise it will automatically use the first CUDA device found if you don't.

Using CUDA may or may not increase your speed, but one thing for sure is it will decrease the load on your CPU. One thing to note is the rpcminer-cuda miner does not support the new Stratum protocol, which most mining pools are switching to.

And yes, with OpenGL mining (at least for Nvidia cards) it is normal for the core you choose for CPU affinity to be at a constant 100% load. On the other hand from my experience, there is no noticeable increase in CPU load when using CUDA miners.

Get CUDAminer  I'm getting 165 on my 570 with it.

CUDAminer is definately the way to go for nvidia cards.  It boosted my speeds quite a bit over other miners.

Sorry if this may sound stupid, but I thought CUDAminer is for Litecoin only, and not Bitcoin?

based off pooler's miner. You can switch the algo with -a

I've been trying to get cudaminer working with my 3 Titan's... for the few seconds it appears to work I see north of 330kh/s but if using autotune the app crashes, and if using no-autotune I get driver crashes
quite annoying I can't post in the main thread to help or get help :D

Drivers are up to date?

yep, 314.22

also just downloaded and tried guiminer for BTC (rpcminer-cuda) and that fails to start as well

I've got the CUDA 5.0 SDK installed too

Try this version of rpcminer-cuda:
https://bitcointalk.org/index.php?topic=99523.0

They have support for newer CUDA versions

Computer in another language?

nope, is English

thanks for the link, will try the other version tomorrow
