Could be a cooler, on the back of the board for the VRM`s.
If that is the case and you took it off to fit your V8.
Voltage Regulators run very hot indeed. They need to have some sort of heatsink on them.
Because when they become to hot they become unstable.
The end result is a crash as the voltage to the cpu becomes too low, or can become too high.
Coolermaster put two fixing kits with the cooler for just this type of situation.
Depending on your board Type.
One with a retention plate for the back of the motherboard, and another kit incase you had said
Vrm cooler on the back.
So I'm pretty much screwed coz I threw the Motherboard Heatspread away lol Then again, I did try to use the other fitting kit to install the v8 on the motherboard, but the heatspread is still in the way and I really can't get it on, thats why I took it off
Maybe you should take the cooler off clean it and re- apply some more Thermal paste.
I had one other thought as to the cause of the crashing you talked about.
And that is to check the Vdimm voltage of your ram sticks. The voltage may be set to low in the Bios for them.
As you get memory sticks that can work at 1.8v ,1.9v or 2.1 volts.
I would have a check see if the bios has set the right voltage if not, set them to the right voltage yourself.
Also do a heat test when your cpu is at idle then under load ie playing a game.
Shaun O, I have done what you've told me to do. But it is still no use. Instead, I've even tried using my old fan, but the problem still exist. I have an OCZ 600watt PSU, which i think it's more than enough for my hardwares to run on. But like I said, problem still remains
