Title: Anyone getting this: [CGMiner] Error -6 (Command Queue) on (2) 7970? Post by: Dalkore on June 06, 2012, 07:48:53 PM Has anyone gotten - Error -6 (trying to establish Command Queue), what happens it that is drops GPU1 and it says DEAD under the mega-hash performance and I only get output from GPU0. Even it I try, restart GPU, it doesn't work. I have to quit and then open CGminer again and that gets it back up. It seems to happen every 36 hours or so.

How far down is too far ? I am running 300Mhz Mem Clocks on 15 7970s and have not had a problem... A small performance loss, but the power (and heat) savings more than makes up for it. CGMiner 2.4.2 (for GPU Clock control and mining, of course), using Afterburner for MEM Clocks and Voltage Control. Code: GPU 0: 67.0C 3260 RPM 55% Fan | 960 Mhz GPU 1.02 V 300 Mhz MEM | 564.9 / 565.4 Mh/s | 99% Load | A:3077 R:27 HW:0 U:7.87/m I: 9 This is simply a copy/paste from my monitoring app, with proper voltage levels added for reference. Today (when I took this copy/paste selection above) has been the hottest day this year, for my miners...I am sweating, just standing in front of them yet they are hardly breaking a sweat.....
