I'm curious to see if more than just ACC code updates were done in the new F2B bios for the UD4P. More specifically, the 1T/2T command timing is broke (hardset at 1T) and Bank Swizzle is always enabled as well in F2.

I'm getting 4 cores without ACC on the GA-MA790FXT-UD5P with F3b bios. Still have sound problem. I thought turning off ACC would disable the 4th core and eliminate the scratchy sound but no. Too bad...4th core is strong.
Back to testing.

Same with the UD4P. Looks like I'm stuck with 4 cores now. Oh well, it's strong too, so I'm not complaining.

If you pull power from the board and hit the CLR CMOS button, then power back up. you will have 3 cores again. Atleast that is my experience.

Shut it down, disc power and let it sit for a while and cool down. I lost 2 cores on my 720 trying to crack 4.4 on air.

Was fine after I let it sit awhile. 4.4+ was easy with only one core showing in aod :D didn't bother validating or taking a pic. Apparently 1.7v ticked it off.

Yep fine now, remember the 720BE revisited thread, all the benches were shortly after I lost 2 cores. Wanted to make sure it was still up to the task for the TH competition. Funny thing is it may actually unlock, apparently the bios's I tried it on are known not to work. I will try unlocking one tommorow, have to knock some gay 4 core multithreaded submitted benches out of first place on the bot.

Thanks, back to 3 cores and sound/color is fixed too. Still on F3b bios.

bro20000 - Yea, I'm just killing time waiting for a 9x5 too. Never had so much fun waiting ha ha.

Edit: I've been waiting since 939! But 5 of them keep me entertained.

Have got to admit the F4g is the better of the two bios out currently got mem up to 836Mhz Stable 7,7,7,20 timing with the F3b that wasnt possible!
I cant wait for the Quads to come out i do think intel will be in for a shock!

Looks like Gigabyte pulled the F2B bios from their website.

I tried it out last Friday and along with unlocking the 4th core, I got sound corruption as well. So I'm back to F2.

They didn't fix the 1T/2T timing control... it still stays at 1T regardless what it's set at in the bios. Same with bank swizzle.

Just to make it clear... this won't work on non-AC mobos like the DFI UT 790FX-M2R..?

i want to get the X3 720 with the Gigabyte GA-MA790FXT-UD5P or UD4Pto use also DDR3 1600 Ram . Can any cpu 720 unlocked to 4 cores? Or only the 09/04 made? It's difficult i think to find in the market this date of build. Does anyone where to find it?

^@dimi80, I got mine at Tiger and they had a row of 0904's.

So far i'm 1Hr prime stable (stopped by me) at 3.5GHZ on my 720B.E with X4 cores enabled. This is on my DS4H.

Will be getting a UD5P soon though.

This is my max OC on 4cores 3.9GHZ and 3.8 is Max benchable so far. I havent gone over 1.5V though :)

my question again. It works only the 09/04 ? And witch AM3 (for ddr3) board did you prefer?
I found a 09/04. will it work?

@Shoalin95--Thanks I'm glad it worked out as a Quad

@Dimi80-- Read thru this thread dude, it shows which ones might be quad. Its a roll of the dice though
