Title: Best CGMiner parameters for Sapphire 7950. Post by: stevedolly on January 27, 2014, 09:47:50 AM Hi, Anyone have any suggestions for the best parameter setup for this card.
I have 5 of them and can only get ~520Kh/s out of them. I find best performance is using -I 18 --gpu-vddc 1.068 --gpu-powertune 10 --gpu-engine 900 The cards will overclock to 1000 but with no better hash rate (only increased power and heat) With -I above 18 a few hardware errors creep in.

Have you consulted the mining hardware comparison chart? https://litecoin.info/Mining_Hardware_Comparison Also, with CGminer come a GPU-README.txt and a SCRYPT-README.txt with helpful hints on how to find the best settings for your card. Hope this helps. |
