Title: (2) XFX R9 290X GPUs - different Hash Rates Post by: JCR27 on March 03, 2014, 01:58:24 AM Hi
I have (2) XFX R9 290X GPUs and I consistently get different (seems consistently different) Hash Rates: Running: Windows 8.1 - 64 bit, CGMiner 3.5 with these settings: --scrypt -o stratum+tcp://eu.coinmine.pw:1111 -u UN -p x --thread-concurrency 28500 -I 20 -w 512 --shaders 2048 --lookup-gap 2 --text-only --expiry 1 -s 1 --no-submit-stale --queue 0 --gpu-powertune 20 -g 1 --gpu-engine 936 Hash rates I get (pretty consistent): GPU0 ~ 710 kH/s GPU1 ~ 860 kH/s Any suggestions for getting consistent (~860 kH/s) for both GPUs? Any suggestions for improved Hash Rate? Thank You Jim Title: Re: (2) XFX R9 290X GPUs - different Hash Rates Post by: mrmork666 on March 04, 2014, 01:18:34 PM http://www.overclock.net/t/1457836/determine-hynix-elpida-memory-on-290x-cards-based-on-product-number-before-buying-them-confirmation-needed-please-help-if-you-have-a-290x
