CPU result validation fails whatever parameters I use #65

Closed skubo closed 10 years ago

skubo commented 10 years ago

Using current master branch from 16.1.2014 and GeForce GT 630

I keep getting CPU hash validation failures no matter what parameters I feed to CudaMiner.

Debug output shows this: DEBUG: hash <= target Hash: 000007747bc6fd19cdc6b5915954734463df965d35b902741c5fdf9777023a31 Target: 00000ffff0000000000000000000000000000000000000000000000000000000

Platform is Ubuntu 13.04 with Nvidia driver 319 and cuda 5.5

Am I doing something wrong?

cbuchner1 commented 10 years ago

how current is the branch? ;) I made some commits today that fixed an autotune problem (out of memory error).

Is the GT630 a Fermi part or one based on GK208 Kepler?

Are you hashing scrypt or scrypt-jane coins?

Am using the one after your commits today. (had the validation fails before and after these)

Autodetect always falls to F... configurations so I believe it's Fermi.

I'm mining scrypt coins

Just found that if using legacy mode, it actually works (with lower hashrates of course...) It's definetly not Kepler, found that out now.

Can be closed. On lastest master Fermi kernels verify on CPU now on Ubuntu 13.04
