Looks like you have done some thorough hardware testing.
When RAM passes memtest86+ it doesn't guaranty that it's 100% OK, it still might be causing problems. Memtest86+ is an indication that the RAM possibly not the cause, but the settings from CPUZ can show some possible setting adjustments.
I see that you have previously un-installed CoreTemp and Speedfan, were the temps normal? What temps where you running at with the system stressed?
If possible useCore Temp to check the CPU temps when at idle, under load and/or testing.
Let us know the minimum and maximum temps you get.
Go to your BIOS and tell us what the CPU, RAM and CPU integrated North Bridge (CPU-NB) voltages are.
You can get the actual CPU voltages from CPUZ CPU tab but, the other tabs show the recommended voltages not actual.
An 'el-Cheepo' PSU can cause all kinds of issues, you should consider a good quality brand with more power than you think you need, 650 to 750W should be enough. The more hardware attached the more power you will need.Already done.
Just noticed your PSU in system specs, the CORSAIR HX650W modular is a good PSU and shouldn't be causing you any problems.
First thing I noticed is that RAM appears to be for Intel CPUs and boards, they will sometimes run on AMD boards but are a known issue.
You may need to RMA it for some AMD RAM, lets try a few adjustments first.
The CPUZ Memory tab shows you what the RAM is set at currently, the SPD tab is the manufacturer recommended settings.
Your AMD CPU's integrated memory controller is known to not like running RAM at 1600 (800 MHz) so I would recommend leaving it at 1333 (667 MHz).
Your SPD tab, JEDEC#4, says you should be running at 685MHz, 667MHz should be fine it's not enough to try changing, timings at 9-9-9-25 and 1.5v.
The Memory tab shows the command rate 2T, this will help with stability, just leave it at 2T.
I would try these settings and see if you still get BSoDs, if you are then let us know the CPU-NB, or equivalent, voltage.
Sometimes a bump in the NB will help the memory controller and give you more stability.
I've just read the first page and last page, will view the rest and edit if necessary.
EDIT:
If you're trying to run 16GB RAM, or even 8GB then you will need to bump your CPU-NB voltage this is for the CPU integrated memory controller.
From your MOBO manual:
- To enable successful system boot-up, always nsert the memory modules into the DIMM1 first.
- Due to the chpset resource deployment, the system densty wll only be detected up to 15+GB (not full 16GB) when each DIMM s installed wth a 4GB memory module.
What is your CPU-NB voltage?
Page 3-19 of your MOBO manual.
If it only shows 'Auto' then add the minimum voltage and tell us the new voltage reading.
Stock voltages for the PhenomII CPU-NB should be between 1.15-1.30v.
Is your BIOS American Megatrends?
How long did you run Prime95?
