FYI you are getting a ton of hardware errors

Sonny,

At this time i am running at about 58-60C. I have been running 24hrs with no issues after re-install and adjusting USB/PCIe sleep settings.

Just so i don't want to leave the thread with what ended up being the issue with my Sapphire 7950.

1. I did not have the set allocation at the beginning of my batch file. I did do it in DOS but for some reason the memory was still being allocated.  
What this did was allow me to get over the TC - 8192. Also I added the "del *.bin" at the top of the batch file because of what i read the .bin files can cause issues.

del *.bin
set GPU_MAX_ALLOC_PERCENT=100
setx GPU_MAX_ALLOC_PERCENT 100

2. Also i re-installed windows due to GPU-Z was telling me my AMD drivers were having errors. I was playing with different drivers maybe they all did not get removed properly and causing conflicts.

3. I was having a issue where every hour or so my PC would shut down and i noticed that the USB devices were going to sleep. I had all ready ran through my power settings ensuring they were set to "never sleep/shut down", but i did not do it to the USB or the PCIe settings so i am assuming that did help and or issue #2 might have had something to do with that as well.

I am running at about ~660 kh/s.

Thank you for all the replies!

Yes i am using that same card to run my monitor. Do you think it would hold me back from 350 Kh/s to the projected ~550KH/s? My board does not have a on board graphics card so i can get a cheap one just to run my video. I used another set GPU/MEM clocks with the 8192 i got to 580 kH/s but my CGminer said "Dead" in the morning.

Hello i have a Single Saphire 7950
I was only able to run reliably at 50c 120 kh/s and now i can get to 350 KH/s with no hardware errors.
I have read that i can unlock my GPU and allow me to shut off boost and the Thread concurrency/memory limits which im hoping can I get to the 500-600 Kh/s that this card is capable of, if some one could help me with some info on what bios i should use with some setup help/settings, that would be great.
The max i can get my settings to with out a ton of hardware errors,

TC = 8192
I = 13
Look up gap = 2
