Cpu help needed...please read

I was having some memory issues with my motherboard, and I'm pretty sure the issue is with a DIMM on the motherboard. It ends up causing games to crash/lockup randomly or more recently, freeze up completely when I'll be playing. I've had these issues occur recently: I'll play Guitar Hero on my PC and then the screen will sometimes go COMPLETELY purple, however the game still keeps on playing music as thought I was playing the game, despite me not hitting a note. When playing Oblivion, sometimes the game will lockup entirely and I'll have to reset. Etc, etc. I ran memtest, with each of my ram sticks and I kept getting the same error, regardless of which DIMM I placed the ram in or which stick out of the four I used. I even tried it with ram from my previous computer, and I still got errors in memtest at the same point and teh same amount. Basically once it reaches the test that states "Changing 0's to 1's or inverting 0's to 1's not sure which, it crashes at about 21% stating there are errors. So all in all I'm sending the board back to the company.

Now to the point in this thread. After installing my dual core, I kind of lost place of where I put the cover that came with the CPU to protect the gold pads from dust/etc and now I need to buy another one. The only problem is I have no idea what that piece is called, nor where I could possibly purchase one. My room is rather dusty, and I have no place that I can truly feel safe keeping my cpu exposed and not cause damage, so I need to find one before I can send it to the company for repairs. Any help is much appreciated, and I thank you for reading all of this. Thanks again and take care.

P.S. I have a XFX 680i SLI motherboard, so if anyone can further verify if my issue might be memory/motherboard related would be much appreciated. Take care and have a great day.

No overclocking. Everything at stock settings. I tried running the memory at the suggested voltage of 2.1V but it didn't change anything. So I put the voltage at normal.

Although the advertised timings on my ram are supposed to be 4-4-4-12, putting them at those settings causes LOTS of issues and BSOD's on my computer so I left them at system setting of 5-5-5-15.

ram voltage is too high

set the am to 2v

I was mistaken about the advertised and current timings, but did try your suggestion to no avail. Memtest still crashes when it tries to move the inversions at 21%. Advertised timings = 3-3-3-12, bootup timings = 5-3-3-15.

Do you know what the CPU cover is called? ^^;;

alright I'll try it...
