Title: 2 x Sapphire Vapor-X 5870
Post by: joker060 on July 01, 2011, 03:20:05 PM
Cant seem to hit that 800mh/s mark.  Right now hitting 775 mh/s consistent.
 
I have the card at 900/600 which is the most MSI Afterburner seems to let me do.  I have tried setting the values and restarting the machine but it wont let me go any furhter.

Flags on GUI Miner -v -w128

set ram to 315 and core 975+ (I'm at 992 and get 410 Mhash/s)

Windows? use this (http://www.techpowerup.com/downloads/1128/AMD_GPU_Clock_Tool_v0.9.8.html) tool.

The AMD GPU tool doesn't find my cards.  Says there is no valid devices.
