Thank you very much for this Nvidia guide!

I was running nvidia-352 drivers and cuda 6.5 and it didn't work because of an "unknown error". So I installed the newest nvidia-361 drivers (and apt-get uninstalled cuda). Now every command didn't cause any errors but if I enter into the terminal for the 750Ti  "nvidia-smi -ac 3004,1476" nothing happens if I look into the nvidia settings and at my hash rate, which is still 5.2 MH/s with the cuda version (cmake -DBUNDLE=cudaminer -DCOMPUTE=50/ ethminer -U) of Genoils ethminer.

What OS? What driver version?

I have observed memory clock changes having an impact on hashrates.
So, I think clocking your memory is worth a try.

it's normal that one instance of ethminer consume 60% of my celeron computer? can this run six gpu if one already consume 60%?

1.0.5 is up.
- Compute 3.0 works again. 11.9MH/s on a g2.2xlarge AWS instance. So that makes 47.6MH/s for a g2.8xlarge...
- Refactored OpenCL code. Down from 83 to 78 VGPRs on GCN. 14 to go...

This means you can run EC2 spot instances for free most of the day and make a small profit at it. 

Would be cool to set up a small ec2 node that auto-launches g2 spot instances based on spot and ETH pricing.

speed on amd/opencl and cuda compute 5 is the same for all my 1.0.x builds.

I built the current master release for Ubuntu 14 yesterday without problems. What is the cmake command you've used?

what commands did you use ?

bundle can also be "miner" if you have AMD.

now i get

Have you gone through this first?

It installs more than you need, but at least it installs what you need

Anyone here mining with 2gb cards? If yes, what is the card? And how much hashes di u get?

Do you have AMD-linux version?

ok so I if I am rigth, than we need to compile the source in Visual Studio. But I have an error can't open pthread.lib. I downloaded this lib, but where I need to put it?
