Built my most recent rig with the MSI 870-G45 Mobo, Phenom II x2 550BE CPU, and an Corsair H50 cooler. I quickly had a stable overclock at 4.0 Ghz at 1.45v. Used like this for quite a while, no problems.
A friend of mine (tw34k here on OCN) started doing a similar build shortly after, so I took the opportunity to upgrade CPU, I bought a Pnehom II x4 955BE and sold him the 550BE.
I install it and immediately get a stable overclock at 3.6 Ghz at stock voltage (1.35v). I take it up to 3.8 Ghz at 1.4v and its stable, then I bump it up to 4.0 Ghz and while booting into Windows to test stability the computer shuts off.
Initially I think its the PSU because when I jump the pins on the 24 pin connector it doesnt turn on, but then when I uplug the 4 pin CPU power connector the PSU does turn on. Mobo is fried.
I take it out and inspect it, nothing visibly broken, no burned up mosfets or capacitors, or anything, but the CPU power circuit is obviously shorted.
After looking at some specs on the mobo I see that I was above the recommended CPU wattage for the mobo.
I didnt have enough money to get a significantly better mobo, so I buy a MSI 870A-G54 which is very similar but has an 8 pin CPU power connector and thus can support a higher wattage CPU.
Ive been running this board for a couple months now, but havent overclocked beyond 3.6 Ghz at 1.35v for fear of another failure.
