Hey everyone,
Thanks for taking a look.
I currently have a issue were I am not getting max or even close to max hash rates for my cards. Once I start getting close to the hash rate I am looking for I get a (in gpu-z) a 99% to 100% to 64% spikes in the GPU load.
Rig specs: Corsair HX1050 3x 7950 Sapphire 3gig http://[Suspicious link removed]/d5optz5 Intel i3 3240 GIGABYTE GA-Z87X-UD4H 4gigs ram (I will get model # later) hhd 500gig 5400rpm Windows 7 64bit Powered raiser for 1 card
( I am also having this issue on my 2 gpu rigs with no raiser)
They are placed on an open air mount with fans blowing directly over them.
Temps on the cards are in the range of 68-75
Currently I am using a 8192 I-13 1000 core clock and 1250 mem clock
BACKSTORY: I was having power issues with my wife not being able to use the hairdryer with out tripping the breaker and turning off all the rigs. I had a electrician come out and add more circuits to the panel aka he put a few plug outlets under the panel since the machines are in the same room. I now have no issues with the hairdryer and I have added more machines and they all run.
Prior to this I was able to get 650khash from each card on my 2 computer 2gpu setups tho 1 machine was starting to have the 64%gpu load issue and I figured it might have been do to the fact that it has been shut off a bunch of times do to the hairdryer issue. Prior to this it was running 650khash for two weeks with no issues. I replaced the power supply (same problem) replaced the motherboard. Now I am only able to get around 515-550khash on the cards.
setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_USE_SYNC_OBJECTS 1 cgminer --scrypt -I 20 -g 1 -w 256 --thread-concurrency 24000 --gpu-engine 1050 --gpu-memclock 1250 --gpu-vddc 1.087 --temp-target 80 --auto-fan -o This was my cgminer settings when I was getting 650khash. Now I can't get to work. I have tried to get 21712 working but I get gpuload issue.
Currently the only setting that works without having the gpu load issue is a 8192 I-13 --gpu-engine 1025 --gpu-memclock 1250 Drivers are 14.1 I have also tried the 13.12 <a href="

I am starting to think its because of the power from the wall? Please help! I have done a ton of my own research and this is my first post regarding an issue like this.
I really do appreciate it.
