Yeah... about this unlocking business. AMD is urging (actually mandates that) the motherboard manufacturers upgrade the SB750 microcode to block any future attempts at unlocking any CPU. So if you have an already patched BIOS, you won't be able to unlock. Also if you want a new BIOS for your motherboard it will surely have the AMD patch.

So stop it.

Apparently not everybody here has a 720 BE. :rolleyes:

What about Biostar TA790GX with SB750?

Thats the board I got in my gfs comp with her 7750. When I got it I tried my 720 in that board and it did not work, and I have the correct batch of 720. It's really just a luck thing, I still would say stick with what you got, it's a very nice setup!

Have you tried to unlock her 7750 yet? Apparently its been done with an Asrock mobo.

I heard about that to, You can apparently turn it into a 7750 Quad Core.

I use a biostar 790gx board and it unlocked my 720BE. am running 3.4Ghz 4 cores prime stable. Rite now have downclocked tht to 3.25 Ghz as it uses stock voltages at that setting. Batch for my cpu was 0904

I been working on that, it didn't unlock with the BIOS that came on the mobo. Gonna try and update it a few versions and see how lucky I get. Although it really won't bother me if it doesn't I have a 9850 BE and that thing clocked like ass, and the 7750 just clocks far easier on the stock fan/heatsink. If enabling 2 more cores kills the OC I'll prob just run it as a dual core as all she does is game.

Not really a 7750, technically it's called one, but it's an exact twin to a 9950 BE. Check the wPrime Thread, in the Dual Core Section. Then check Cdawalls 7750 and ChickenPattys 9950 (running on 2 cores), they are both within like 20mhz OC of each other and only .2 difference in wPrime 32M.

I was able to unlock the 4th core on my PII 720. With Bios 0603 if I enabled ACC the lights on the video cards would just stay solid and the system would never boot. Flashed to the 0703 bios and I have the 4th core enabled. Had to play around cause with 3 cores I could run HTT upto 2800Mhz but now the system freaks above 2000Mhz. I also had to tune the OC down cause system was very unstable @ 3.6Ghz all cores...I can live with 3.4Ghz

By the way this is from batch 0903(Sorry Erocker

)

Yeah, I finally had to settle at 3.45 GHz OCCT stable with 4 cores. It's still a good OC IMHO.

kenkickr · Apr 27, 2009

Mine is not stable with the 4th core when it comes to Prime95 and OCCT. Within a sec the system locks up. I can run 3dmark06 and Vantage all day but pretty sure they are not going to stress out ALL of the cores.

Guess I'll have to see what the 7750 can do now.

What the hell is it with non-720BE owners getting so damned butt-hurt about us unlocking our chips? :rolleyes:

Who the hell cares, and what does it matter to them anyways? Are they just pissed because we got a $135 quad core that keeps up with $300 intel quads in gaming?

edit: FYI, I purchased my 720BE/AM3 mobo on release day, before anyone even knew about unlocking.

Since my bios (F3b in my case) functions perfectly with my mem @ OC, why would I want to screw around updating it anyways, and so why the hell should I care whether future bioses don't unlock?

My 720BE (0904) unlocks on my UD5P AM3 and is 1 hr OCCT stable all four cores @ 3.6Ghz 1.475v, and bench stable up to 3.8

I just reformatted so don't have my screens, right now I am on stock air @ 3.4 because I sold my air cooler and am switching to a bong cooler soon for the summer.

I'm a non 720BE owner and I've been recommending the 720BE... then I've been recommending a SB750 board and 0904 batch

So fun to see AM3 quads at 135$ instead of 250$

kenkickr · Apr 28, 2009

Is there something AOD doesn't do that Prime95 and OCCT do that would cause my system to lockup within 3 sec when the 4th core is enabled? I ask because I played around with it some more this morning and @ 3.4Ghz, 4th core enabled, I just completed a 30min stability test using AOD. I'm going to keep it like this and see how the system works for awhile.

(Update 4/29/09)
Worked great last night! Watched a movie, played some CoD World at War and MLB2k9, and did some video rendering without any issues. This morning was a different story
1. When I turned the system on this morning system locked up just trying to get to the desktop
2. Rebooted the system and started watching highlights of the Cubs game(so close Z) and during Z's homerun shot system locked up again

I don't get it but back to being X3 for good. Now hopefully I can try out unlocking the cores on my 7750
