Hey All!!
Some help would be appreciated much appreciated…
Im fairly new to mining, had my 2 card rig for about a week, running pretty good after a tune.
Last night when I went to bed my two Sapphire Vapour 280x cards were getting 750 and 740 kh at 66 and 70degrees with fan speeds of 2600 and 3100 with the below settings. When I woke up a few hours later the kh is now at 280 and 260!!!! No settings have changed, no burning smell, no fried wires, just a lower khash…
-Windows 7
-CGMiner 3.7.2
-4gb ram
-Sapphire Vapour 280x
-Settings
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
-d 0,1 -I 13,13 -g 2,2 -w 384,384 --thread-concurrency 8193,8193 --lookup-gap 2,2 --gpu-engine 1075,1080 --gpu-memclock 1500,1500 --temp-target 72,72 --auto-fan --gpu-fan 60-90 --temp-overheat 85 --temp-cutoff 95 --gpu-powertune -2
Does anyone have any suggestions as to why this happened and more importantly how to fix it??!?
Any help is much appreciated!!!!!!
Thanks!
