Title: Sapphire 7950 won't reach 600 kH/s Post by: jongameson on January 26, 2014, 01:31:16 PM I've been running this for 2 months, but haven't been able to get it above 500-550 kH/s.
I'm currently putting the blame on the CPU now (Pentium 4 2.8 ghz, 4gb ram, non-SSD hard drive :) i'm guessing the bottleneck lies with the CPU (only 32-bits). is this clearly the issue? or my settings.

Hard drive speed has no bearing on performance... Post your bat / config

I am also struggling getting it over 500-550 as soon as I set intensity higher as 13 I get hw errors?

Others with 6 GPU rigs have no problem running a low-end Sempron in them, I doubt that's issue.
I'm having issues with my 7950 also :-\ My intensity is at 20 though, anything less and my hash rate barely breaks 400... Title: Re: Sapphire 7950 won't reach 600 kH/s Post by: poohbah on January 26, 2014, 06:03:16 PM Google is your friend: "Poor hash rate on Radeon 7900"

32bit is a big problem though. |
