Phenom II X3-720BE List Capable to running 4 cores or not
Guys, after testing several Phenom II X3-720BE, i found that not all version/batch of this CPU can do 4 cores. So, i started to make this list to share which batch can and which batch can't.
Motherboard using GIGABYTE MA790GP-UD4H
List of batch
* 0904 BPAW ------> can't boot at all when ACC Enable, show F2 in debug card
* 0904 BPMW-------> Boot OK, detect as Phenom X4 and then stop, debug card shown 83 code.
*0849CPAW --------> Boot OK, and act normal like Phenom X4.
Share your experience here !

Benny that would suggest that they appear to know about the issues and have put a stop to it? At least if you go by the date codes.

Every Phenom II press sample (not even marked as ES but couple weeks earlier than retail parts) I've tested so far have been worse than normal retails.

They already know about it that's why not all Phenom II X3 can do 4 cores. If they don't know about it all Phenom II X3 will be capable to run 4 cores.

That would seem to be the right way of doing it for AMD.
Use faulty cores and put some good ones in the mix to spice things up and boost sales. 
Nice find.

this is a very good idea. i'm looking at picking up a x3 720 to unlock the 4th core, and would love it if more people posted their results. also, which motherboards are required for this 'hack?'

got my 720 in yesterday, so far i am unable to load windows with 4th core enabled. its a 0904 CPMW. doesnt seem like an out of this world clocker either, so far i am unable to get it stable over 3.3ghz in windows. it is my first phenom though, so i might be missing something.
this was done on a asus m3a79 - t deluxe

Try lowering your OC :-P Or raising vcore. The forth core is obviously a weaker core.

have tried that @ 3.0GHz sir, but still once i click on start (prime95 or occt), i'll get a system lock up. i think i already gave up on getting it prime stable.

I ordered in a Phenom II X3 720 from Newegg on 2/26/2009 and got in a 0851 FPMW stepping and can enable ACC on the MSI DKA790GX Platinum motherboard with BIOS v1.6. If I set ACC to 'per core' I can see four cores, but in Windows it only shows up having three... Frustrated!
I posted the BIOS screen shot and OverDrive pictures here - http://forums.legitreviews.com/about20248.html#p139522

I tried my Phenom X3 720 on the Asus M4A78T-e and it was a no go no matter what setting.
