X2 550 Unlocking & Overclocking Consolidated

[Tom128]

0928BPMW - ASUS M3A78-T - BIOS 1403

Successfully unlocked all 4 cores, but one of them is bad and fails prime instantly. Oddly enough I can load that core at 100% and it will never BSOD though.

Also, I have am M3A78-T and M3A79-T Deluxe both with the new Unleashing bios. The unleashing mode is there but the option to pick just three cores seems to be lacking? I dont have an option for which cores to turn on, just unleashing enabled/disabled.

[Dopamin3]

the latest bios from dfi.com (from july 2009) is supported 100% correctly unlocking
i have question to "NoM$_YesLinux" - ive got the same motherboard as you, but ive got one 3850 and cpu-z tell me that, pcie is working x8 - have you any method to activate x16 mode on single gpu?

i think good stepping isnt guarantee 4 cores - i saw two 0922apmw and anyone didnt unlock 4cores correctly

edit. i uptaded bios to d7jd826 - that bios isnt supported correctly unlocking, acc options isnt working, but d7jd826 bios is better for higher htt, mobo is booting 290htt ;]

All the newer DFI bios unlock I think, read this: http://csd.dficlub.org/forum/showthr...8833#post78833

just received a 0925 bpmw what are the odds? any luck with this one? I dont see it in our database/.

There are a couple of those 0925BPMW's listed here with success. Note that page is mostly from posts in this thread and more up to date.

[EvilBlitz]

Tom128 in the M3A78-T there is an option to disable cores in the 1403 bios. It is on the same page as the unleashing option.(has been there since shipping bios for me)

This thread is not updated any more so I'm not posting more unlocking results, I have more 550's to show, mostly 0925, APMW, BPMW, CPMW and APMW are not unlocking very well, more they come more they fail to unlock, BPMW is better batch so far and the last one I have tested yesterday (CPMW) is a REAL BEAUTY!!! I'm in love with this cpu! Test configuration is from my Athlon II X4 620 thread, just switched cpu's to try it in the same watercooling conditions as 620 currently...

This is only idle stable but most of the successfully unlocked 550's that I unlocked were overclocking around 3800 idle stable with that cpu vid, so this one is my precious!

My personal X4 550 record is going down for sure

I cannot agree: latest BETA for DFI 790FXB-M3H5 (D7SD826) - unlocking X2@X4 is NOT possible, but official (D7SD727A) unlocking my CPU (0929GPMW).

hey Cele303 have you come across a 0932fpwb (550be)?

[Cele303]

No, I didn't see any 30+ week 550

[Tao~]

0932FPBW unlocking (and 2 hr prime stable)
Did this on a Gigabyte board, and just enabling ACC on all cores didnt work. Then I set 'EC firmware selection' to Hybrid and then it worked . Is that Gigabyte typical ,I havent seen EC firmware mentioned otherwise?

PS:i thought i had a SB710 :?:

Hi

Only BIOS with D7SD***A can unlock.

Be well...

[Tom128]

Tom128 in the M3A78-T there is an option to disable cores in the 1403 bios. It is on the same page as the unleashing option.(has been there since shipping bios for me)

I am either blind or something is up then. I go to that page (CPU Settings I believe). I set ACC to "Enabled", which then causes the menu option Unleashing Mode to appear, and I select "Enabled" for that. Setting it to Enabled does NOT display a third option to select which cores to unlock like I expected (and what it looks like in screenshots) and I dont see anything on the screen anywhere that has the option. I tried hitting F4 for more options as well.

Confused

I believe he was referencing the processor downcore option,it is above the ACC option in my M3A78-T bios.I haven't got the option shown in the screenshots to choose cores.

0925APMW - Gigabyte GA-MA770T-UD3P - F2 - Success
About 5 hours test in Prime95 without any errors

Hi Vomak,

I tried unlocking my 0925APMW 550BE on MA770T-UD3P MB without success using F2C bios and also F3. Did you try any of these without success before switching to F2? And what settings did you use? (just trying to find out if I should make the switch to F2). Thanks.

[YuDi IzzY]

Hi all,

Sold my 0925CPMW that didn't unlock and got another stepping with the following great result:

0922MPMW - Chickenlittle - Asrock A780GMH/128M - P1.20 - Success

This seems to be a good stepping for unlocking.

Cheers

memel, did you notice the voltage in your screenshot of your PII 545 Prime95 @X4 3,6Ghz 1,42V (Biostar TA785GE)? It certainly is 1337!

Well done
