Title: hashrate decrease Post by: ses7404 on January 21, 2014, 09:06:31 AM I've 4 machines mining scrypt on GPU. Im every machine BFGminer at startup has great performance with really high hashrate. Hashrate slightly decrease passing hours till it stabilize at a really lower hashrate compared to startup.
Could it be normal behaviour? Thanks Title: Re: hashrate decrease Post by: vpasic on January 21, 2014, 03:54:25 PM which gpu-s?

7850 starts at 700kh/s then slowly decrease and after some hours is at 150-160kh/s Title: Re: hashrate decrease Post by: vpasic on January 21, 2014, 06:55:52 PM are you watching temperature of your card?
what about other 2 gpus? 7850 should give you around 350kh. can you try with cgminer 3.7.0 and add this in to your command: -I 17 -w 256 --thread-concurrency 8192 |
