I have an AMD Phenom II x3 720 black edition processor (2.8Ghz) in a Foxconn A88GMX motherboard. I have an ATI raedeon 7790 HD fermi graphics card, and 10 gb of ram, 2gb of which is an offbrand, and 8gb which is Team Zeus Yellow DDR3 240pin. My mobo comes with ACC and its even advertized with a core relaser. I can succesfully unlock, boot, and run windows and many games (League of legends, FireFall, Assassins Creed: Black Flag....) and I'm good for about 20 minutes and then it just crashes, and reboots. I'm not sure what is wrong, and I'm not sure how to diagnose this. I don't think its a power problem, because it wouldn't make it windows if it was, correct? I'm just not sure where to go from here, and this is my first OC. I'm running stock cpu heatsink and fan right now, but gettting a new one soon. I was hoping to get the 4th core stable first, then try OC'ing it later, after i get the new cooler.

I've been looking for days now and don't know what else to do.

The core was disabled because it was defective. You could try boosting your vcore a bit. That may give you more stability. Maybe.

Bump vcore to about 1.375 - 1.4v and enable the core unlocker. If that doesn't work, your pretty much out of luck.

I would remove the "off brand" ram. Run with just the 8gb and see how it does.

^this 1st

Since you can boot windows, it seems that your extra core is at least marginally stable. You are really going to have to narrow down the cause of your crash before you can determine exactly what is causing trouble. vcore might help, but so might nb or cpu-nb voltage.

Are you getting any kind of strange behavior, such as the computer becoming very sluggish and the schedule refusing to load up cores fully even when running stress test software?

the "off brand" memory won't cause any trouble so long as your RAM timings and speed are set to accommodate the weakest DIMM in your machine. If you suspect memory problems, I recommend looping memtest86+ for awhile to find obvious memory read/write errors.
