For CUDAMiner version 10/04, GTX650 Ti on Windows Litecoin mining at ~80 khash/s, autotuning takes about 3~5 minutes. There seems to be some problems with Bitcoin mining though (-a sha256d): 1. NULL displayed for GPU device (regardless of device specified) 2. very slow speed (~1 Mhash/s) compared to other current miners (e.g. OpenCL with poclbm, and CUDA with rpcminer-cuda ~80 Mhash/s)

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 Get CUDAminer I'm getting 165 on my 570 with it. https://bitcointalk.org/index.php?topic=167229.0 Sorry if this may sound stupid, but I thought CUDAminer is for Litecoin only, and not Bitcoin?

Try the newer rpcminer-cuda: https://bitcointalk.org/index.php?topic=99523.0 Or try CUDAminer and use command line option '-a sha256d' for Bitcoin mining, or '-a scrypt' for the default Litecoin mining https://bitcointalk.org/index.php?topic=167229.0

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.

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. To set the gpu used with the rpcminer-cuda of GUIMiner, you just specify it in the "flags" box. Put "-gpu=0" for the first GPU, and "-gpu=1" for the second GPU and so on...

Hey there! fr33d0m from Michigan. Heard about BTC quite a while back, way before all this hype now. Unfortunately I didn't buy any back then, and just starting mining a few days ago. Not in it for the gold (it's not like I'm getting anywhere with my Nvidia GTX650 anyways lol), but it does seem interesting knowing you're helping the network.
