Title: Help with CUDA Miner?
Post by: spartan117x7 on November 06, 2013, 02:00:12 AM
Hi, I got cudaminer running perfectly except this error keeps on showing up.  The only parameter I have is --no-autotune along with my url, worker & pass.   What is going on?

You might have chose a configuration that the ram on your card does not support. Memory usage can be estimated by calculating  blocks x warps x 4 MBytes   where your -l argument to cudaminer specifies blocks x warps.

I autotuned and now have the values -l L30x3,L30x3,L4x2    Still has the validation issue with the cpu.  My gpu definitely has enough ram, 1896mb for the L30x3 one (gtx 295) and 512 mb for the L4x2 (9400gt).

Hi,

I'm not trying to be a troll, but why would you want to mine with a GTX295?

Accoring to https://en.bitcoin.it/wiki/Mining_hardware_comparison you could get about 100 MH/s using 289W.  For about $20 you can buy a Asicminer USB block erupter that only uses 2.5W and mines at >300MH/s - check out ebay!

Cheers,

Um, you know cudaminer is for Scrypt coins only. ASICminer's USB block erupter can only mine coins using SHA256. Also, Cudaminer is not for SHA256, its completely incompatible.

I didn't know that - thanks!
