Could you give us some info regarding board, etc? Off the top of my head, it sounds like you have turbo still on, as well as some power savings stuff, but without knowing your mobo, I cannot really guide you for any additional assistance.

This^^^^ Obviously you're not running the Fx 8320 on the M2n68
In most cases from what I've seen dropped workers usually means either lack of Cpu voltage or Cpu Nb voltage. Again more info can help us help you.

Ahhh I misunderstood. I thought you were experiencing core throttling, but it sounds like 2 cores are failing Prime 95 out of the 8. I hit a nice little vcore wall right around 4.2ghz on mine. Really had to pour on the vcore to get it stable at 4.3ghz. As all chips are different, you could be hitting the same wall on your chip.

Try slowly bumping the vcore up, but from my understanding that board is going to have some issues overclocking an 8xxx series FX. IIRC, it has a 6+2 VRM, no LLC settings, and questionable MOSFETs to begin with.

You need to remember these 8230E chips are binned for rather low vcore at 3.2ghz. It's gonna take a bump to move them along the speeds of the normal chips. According to others, mine is behaving at 4.5ghz as the rest of the FX series does. That thermal headroom you had at 4.0ghz disappears fast the closer you get to 4.5ghz. I cannot really push mine harder without better cooling, but do keep an eye on your vcore and watch for both droop and instability. My understanding is that the new MSI boards use questionable MOSFETs and therefore are prone to failure.

I replaced my PSU with a 800 watt gold rated corsair , ill definitely check into that drop. I think another bump in vcore and I should be more then stable it only dropped 1 core instead of 2 this time after 30 minutes of running it
on prime95 also my memory is set to 1066 but it has some issues at 1600mhz

Looks like you're OC'ing the bus. FYI, the multi isn't locked!
OC'ing the bus right off the bat can complicate things!
You now could be getting Prime95 failures, because of the CPU NB and/or HTT link.

Good catch! Can't believe I missed that
Yeah, I was wondering why was it being OC'ed in a Q6600-esque way.

alright I adjusted some item's (mainly not Oc fsb) I upped the multiplier to 21x201 [4.281ghz] however i didn't increase my volts or drop them and after 4hrs I hit a wall at with prime95 temp at 40c should I up more voltage?.. I'm currently set at 1.325 under load is that too high?..

This is taken directly from an overclocking guide AMD has. As long as your temps stay below 70c on the Socket and 62 on the package you're good.

All depends first can you update your signature so we know exactly what is in the rig. If your running anything 1866 MHz +,you may want to stress with prime blend. Some of these Fx chips need a bump in CPU Nb voltage in order to get ram stable at or over 1866.
