This is my first post so please be gentle. I'm not a great computer expert as you'll gather from my post but as I'm absolutely skint at the moment, I can't really afford to take my PC into a shop.
I had built for me about 2 years ago a PC. It has a Phenom ll X3 at 2.8Ghz. It has a 64GB SSD and a 500GD WD blue secondary drive. I have 4 x 2GB Corsair CM3X2048-1333C9DHX installed.
I decided I wanted to OC as I was starting to get lag when running 4 poker sites, 16 tables, over two screens using Holdem Manager 2 and broadcasting via Teamviewer. I therefore bought a 3 pipe cooler with a fan and went about installing this to my CPU. I had to take out the stock clippy thing as this screwed from the back. When doing it I used a screwdriver, slipped and scored ther board across several tracks. I then tried it and of course it didn't work.
I went out and bought a Gigabyte 970A-DS3.
I installed everything, rebiult windows 7 Pro and it was running OK. Then it would freeze completely and sometimes BSOD.
I have tested all RAM in Memtest 3.5 single CPU (when selecting multi cpu it does nothing) and each on their own in any slot are fine. It's when I pair them I get problems. No matter which two, in which pairing. memtest crashes on test 1 at 57% and reboots.
