Title: [HELP] CGminer - screen flicker Post by: ajax3592 on January 18, 2014, 08:13:51 PM Hello,
I just got my brand new Sapphire R9 290 today. Thing is I did some fiddling around with clocks in cgminer and now my screen flickers vigorously once I close cgminer. It's fine when I'm running the miner. I started the cgminer firstly with Code: --thread-concurrency 27400 --intensity 20 --worksize 256 -g 1 --gpu-fan 85 --gpu-powertune 30 till I tried, OCing memory to 1500 and engine to 1000...then 1050 caused a driver crash, after which hashes came down to 40-50 and I did a system restart and then flickering started happening. Also I decreased the fan to 75. ...also I tried undervolting to 1.125, but it showed as failed (all done within cgminer, no external software used) Max temp reached was 74. I did the system restore, slided the BIOS switch, multiple system restarts - no effect. I think cgminer permanently changes the GPU's properties. Btw whenever I start cgminer, flickering stops and getting normal 840 hashes. Please help me out guys :( Update: No flickering in safe mode Update: FIXED ! :) Flashed BIOS Locking thread |
