I just switched to F3b and now am running four cores 1hr OCCT stable at stock, so I am assuming the fourth core is just fine. I'll do some OC'ing later.
Mine worked just fine by setting to "auto".
What is that driver installation screen all about? Do you install phenom drivers like we used to do with the Opteron 64?Quote:

Have you tried Vista 64 or XP compared to Windows 7 and if so, did you notice any of them been better at OCing?
Just wondering, does OCCT show the fourth core for you guys? Both task manager and CPU-Z show fourth core but OCCT does not...
on a side note I read techpowerup says 4mb can go to 6mb with ACC turned on, and some bios on X4 m3 chips with less cache.
64 bit will probably bsod before getting into windows.
Try reinstalling it... I guess this is just the down side of unlock the 4th core, but all my temp reading are at 0'CQuote:

Havent even started playing with the NB...
On my HTPC set up both Vista 64 and Xp SP3 OCed to the same max thought.
I am going to try both on my phenom as well and perhaps give Windows 7 a try as well.
Regards
Try Windows 7048, great performance increase over 7000
Hmmm...I thought some of the cores weren't stable (the locked ones)
why are you guys so hell bent on doing this? Obviously its been disabled for a very good reason:rolleyes:
the spirit of overclocking is essentially get the cheapest crap and o/c the hell out of it .... or so i thought?
so ontop of o/cing the hell out of it, we're also unlocking extra cpus like ppl did with 6200 nvidia cards to get 6600 performance ( 4 to 8 shaders )

Finally got the validation to work. I would say this 4th core is a fully functional one:up: I tried the f4g bios on this MA790FXT-UD5P but 4 cores not possible for me. F3B works like a charm.

Just so you guys Know....AMD has made request to Mobo Makers to remove that feature capability from Bios.
I am not hell bent, I just spent about 30 seconds updating the bios, another 30 seconds changing ACC to "auto", and another 30 seconds starting OCCT.Quote:

It looks so far that I got one of the good chips that just has a disabled core to be sold as an X3, which is further confirmed by how many have had luck with 0904's.
If I have a good fourth core that I can enable with little to no effort and no negative consequence, can you give me a good reason why I should not enable it?
Obviously that didn't matter to Gigabyte because yesterday they just added bios F3b "Update ACC code for Phenom X3 CPU" that enables unlocking.Quote:

Ditto. Have 4x @3.2GHz stable.Quote:
