Title: 7850 hashing low Post by: cooldgamer on December 31, 2013, 05:00:03 AM I have a 7850 that refuses to hash at anything above 280 kh/s, not really being stable until 260. It is plugged directly into a x16 slot, and is running alongside two 5850's, one of them on a powered riser. My PSU is 750 watt, but I am using a dual molex to 6 pin pci-e adapter.
System specs: 6 gigs of ram 750 watt Thermaltake PSU AMD Athlon II X3 2.9 GHz I'm using GUIminer 0.04 with Catalyst 13.1 and SDK 2.5 Thread concurrency 8124 Worksize: 256 Intensity: 13 (doesn't do any better at higher) Core: 1120 Mem: 1200 Title: Re: 7850 hashing low Post by: ThBitCollective on December 31, 2013, 05:49:11 AM I have a 7850 that refuses to hash at anything above 280 kh/s, not really being stable until 260.
