X2 550 Unlocking & Overclocking Consolidated

New system M4A79T-E / 0921APBW - Success!
ACC auto / Unleased mode on / Bios: 1604

wow!!so high vcore!! carefull as that is the max vcore. 72degree i thinks max temp for x2 550. try to lower 1.4 for daily use as i can get 1.15vcore x2 3100mhz. x4 3400mhz for 1.35vcore

1.50 vcore was just a try.

i'm waiting for my gigabyte to overclock from zero my X2 550 BE with all core enabled.

I think 3400 MHz is possible with 1.35v but if i want to go higher for example 3600 MHz i need 1.45v at least.

With 2 cores i can overclock 3780 Mhz but with a vcore of 1.50v. Temps are good because not over 50° with my Zalman 9700. See you soon probably this week to give you informations of my overclocking

Looks like a fail, not success?

this stepping doesn't exist.
Should this one [ AC0918BPMW ]

[ceemic]

Good chance?

I'll give a try tomorrow on 790FXT-UD5P

[ASharp]

Looks like Cele303 successfully unlocked their 0925APMW chip. I imagine you shouldn't have too much trouble either.

I'll be getting mine tomorrow. Not sure what stepping I'll get since it's in the mail but I'll be sure to report back with results later.

you guys think a 955 with the same stepping as the 550's is the same chip except with the 2 cores disabled? i just got a 955, 0919 epmw which there is a ton of 550's with the same stepping...

I'll be really interested to see your results!

They all came from the same batch so you would think the 955 was binned higher for a reason...

I've actually been waiting to see some results from newer high clocked quads. If it outperforms the X2 550's you should have a sweet chip on your hands.

Keep us posted!

[crazydiamond]

ya ill let you know how it does, i ordered up the gd70/955 combo from the egg for $315 and got the ocz gold amd 1600mhz ram... i was askin cause i saw somewhere else someone say that batch for 550's was good and saw someone on here with their 550 with same stepping priming as an x4 at 3.7xx ghz 1.35v thought it was pretty good.. i got a ton of school work to do the next couple days but hopefully sometime next week ill get to do some real tweaking

Got it thx Zelous

Ahh yeah ok IC now The AC in front of the stepping made me confused

this thread is a must , thanks C-Buzz.
Now everyone can choose what to take.
Honnestly, in my country the "best" stepping i could find is a 0919EPMW , i don't know what to do

to my mind .... it's a good one !

Hi Guy's !

my new Gigabyte MA-790GP-UD4H works fine. The last bios F3 was flashed but i have a little trouble : when i increase the CPU/NB Vid to 1.20v instead of standard 1.1v, the motherboard don't increase the vid. AMD Overdrive tool and Everest Ultimate confirm this.

Another question for overclockers : how do you do to overclock an unlocked X2 550BE to 3.7 GHz with 1.35v (the standard vid). My 0919 EPMW is unstable OCCT at 3.55 GHz with a so vid I'm a new overclocker in AMD's world but my E3110 C0 works fine at 4.25 GHz @ 1.32v

[ASharp]

Stepping is 0924BPMW. Looks like this stepping and board is a winning combo as Rezag1000 was also able to unlock his. :)

I also tried this chip on my ASUS M3A79-T Deluxe with BIOS 0803. I was able to get the board to recognize it as a quad core and even booted into Windows but it locked up instantly when all four cores were loaded using Prime or IBT. Also didn't work with only three cores active either. Didn't work at all with 0905.

When unlock fails, does it fail to post or just failed when stressed?

[Hazzan]

I just buy 0922 APMW 20pcs all unlock and stabil with 3 board DFI LP DK 790FXB M3H5, ASUS CROSSHAIR III, BIOSTAR 790GX A3+
