Please tell me your PSU isn't 20 years old. 2 years
Can you fill in your system specs at the bottom left of any of your posts?
That way we don't have to keep going back to your first post to see them. Sure
I'm going to guess your motherboard is an Asus P8P67 Pro, please confirm. Yes not Revision 3
Which graphics card driver are you using? 2x's ATi 5830's in crossfire not OC'ed
Since you mentioned it, what anti-virus are you using? Avast
What is your BIOS setting for CPU overheating? Need to check, wish I had a drac card since im @ work.
Your Tcase, from Golden's post above, is 72.6°C add 5°C for max CPU core temps of 77.6°C.
Core temp of 80°C, being just above that, is over the recommended limit. Many people go above this recommendation, it will not likely harm your CPU but, I like to stay below the max recommended temps. I have the stock heatink installed. I plan to invest in a new one but I figured since it was doing a memory/cpu burn its unlikely my pc would run that hot for that long.
With everything at stock settings it shouldn't be that high (even with a stock cooler), re-apply the thermal paste on your CPU cooler. Be sure the cooler is firmly attached. Its fine, I have checked it already, stock paste but that will be swapped out soon enough with the new heatsink.
When you ran memtest86+, was that with 16GB RAM installed? Ran 2 testes. Old ram (passed), New + Old Ram (passed no errors)
Can you download CPUZ
and post a snip of the CPU, Mainboard, Memory, and SPD tabs.
For posting the information , enter 'Snipping tool' in the Start button > Search box, hit enter. Select the area you want to post and save to a convenient place. How to Post a Screenshot in Seven Forums Will do when I get home.
Go to your BIOS and tell us what the CPU, RAM and the CPU integrated memory controller voltages are, it's VCCIO voltage on your Asus P8P?. Should really invest in that drac if only it worked in non Dells.
Often with large amounts of RAM you will need to adjust some settings, usually DRAM and IMC (Integrated Memory Controller) voltages.
Let's look at the information requested and make a few adjustments. Drivers:
The drivers are missing for a propriety USB device they are not missing they are just poorly coded and windows does not understand. And unrelated.
