GTX Titan Linux 64bit "result does not validate on CPU" #21

Closed dschmid2 closed 10 years ago

dschmid2 commented 10 years ago

I'm running cudaminer on an opensuse 12.2 with a GTX TITAN with 6GB onboard and 16GB Mainboard Memory. the nvidia driver version is 331.20. I get the "result does not validate on CPU" error permanently. Is there a way or a feature to disable this verification? And what can be the reasons that this test fails?

cbuchner1 commented 10 years ago

the test fails because the GPU computed a result that's not valid. Submitting that to the pool wouldn't get you any shares.

I’m not an expert in cuda, but I guess the kepler implementation is still very young… right?

for me the Titan specific code works fine on a GT 640 (GK 208 chip). 64 kHash/s.

I will be getting a GTX 780 Ti soon for more testing. Expecting 400 kHash/s from it.

I am currently testing on Windows 32+64bit and currently also on Ubuntu 9.04 32bit and Ubuntu 12.04 64 bit.

What is the kernel launch configuration that the autotune has determined for you?
