X2 550 Unlocking & Overclocking Consolidated

[Cele303]

Hi !! Is your 0926apbw stable with this frequency and vcore : 3800 and 1.36v ??? Thanks !

No way, 3.6 1.35V (+ mainboard overvolt to 1.36) X4 stable, 3.6 1.30V X2 stable, this is only screenshot with max AOD OC with box cooler to show 550 successful unlock and healthy cores

Thanks for your informations. I think it's a good step, better than my 0919 EPMW

here is my cpuz validation. i have cool n quiet enabled and the thermal control enabled.

550's look decent

very nice. I have the same board and im having a hell of a time unlocking. cpu is 550BE 0925 APMW.
im using the same bios as you. what did you do exactly to get the board to post?
I set ht link to 1600
vcore around 1.4V
ACC to Auto
coolnquiet is disabled.
am I missing anything? I feel like such a retard with this AMD rig. Its my 1st amd since 2004.

I feel like I forgot how to ride a bike or something.

thx sir, was being lucky only coz i dun think i did something special. what i did was :

1. turn d air cond on bout 10 mins b4 i start benching
2. go into bios, up d cpu multi, up d vid and set d ht link multi to 8x. that's it.
3. turn off gpu (green power utility) & all those c&q related stuffs.
4. save & exit.
5. test d highest clock my old 3850 can handle.
6. run 06.
7. do screenshot.

0925 batch is having kinda high failure rate. i managed to test one 0925apmw on d same board, no luck in unlocking but managed to get it prime stable @ 4.0GHz w/ dual core. lotsa luck needed in getting a 0925apmw w/ healthy unlockable cores i guess.

Okay, It could just be my 0925 550 is not unlockable. I am using the onboard video since i dont have this really setup as my main rig yet. 1st I want to see if the cores will even unlock.
I'll sell this one if it turns out a failure.

@ trans am - when you save your settings in the BIOS and reboot to see if your CPU will unlock, what happens? Do you hang at POST? Freeze/reboot during windows boot-up? Explain so we can figure out whether your chip is responsible or it's something else.

No post period.

Try setting ACC to Hybrid and set all cores to -2% to start (if you haven't already). If 1.400V doesn't work, last-ditch effort would be 1.500V. Beyond that, I'd say it's not unlockable unless there's something I'm forgetting.

Phenom 2 X550 0923APMW all 4 (fore)cores working fine on Biostar TA790GX 128М (78DЕA715), makeing some tests in nominal 3.1Gh and QnQ ENABLED +0.1 Vcore V! It is realy a great processor! Very happy for my second luck! My Phenom II X2 550 now is B50 Quad Core CPU is FULL Stable at 3.6Gh and - very fast! I am very happy with it! AMD the BEST!

that's exactly what i get with d 0925APMW. sad but it ran decently well @ dual core thou...

hi everybody. I'm from Vietnam.

0929bpmw 's 550 code unlocked x4 ok. i have tested 80 cpu 0929 and 75 cpu success. 5 cpu down clock x4 2.2-2.9 test ok.

0922 apmw and cpmw I tested 50 cpu and 48 success but 0925 apmw 4/12 success.

Got the parts yesterday and tried to unlock it. With new bios I was able to unlock the processor to X4 B50 but it was very unstable, locking almost instantly after completing Windows boot. Tried increasing Vcore to 1,4V and also raised voltage on NB, lowered NB clock, CPU clock (2,4GHz) but nothing. Going to send it to my father as he needs it quite desperately. Did a mild OC to 3,5GHz X2 with 1,325V and undervolted P0 to 1,8GHz with 1,075V (did not get CnQ to work so I did it myself with K10Stat).

Any hints on how to make it stable (once I get my hands on it again), NB voltage, CPU voltage, CnQ disabled? I know he'll be satisfied with the performance he's getting but I was hoping for even more (of course).

Just got a 0929. SICK CPU... It kills my other 550 and 940 without even trying.

My old 550 did 3.7ghz with 1.4v on a expensive water cooling build. This 550 is doing 3.7ghz with 1.4v with a 20usd air cooler. Ofc as x4 heres my highest screen http://valid.canardpc.com/show_oc.php?id=679180 . Took it after having the cpu in the board for 30min xD Running it in a Gigabite 785G-UD2H

[SnakePriest]

how long i should run OCCT to make sure that unlocked cores are stable???

[Balb0wa]

i cant alter my nb setting anymore on this, using a gigabyte ud5p.

Cant go higher than 2000mhz wont boot,im sure on f3k bios i got 2200mhz and 2400mhz and it booted fine, im wondering if its because i updated the bios a few time to latest ones, gone back to f3k still no good :-(

Tried upping the nb voltages , cpu voltages etc.


Any ideas?

what cooling you using?

[Snowman89]

what cooling you using?

Water. Think i would call it high end, dont know really Ek-supreme and 2x240mm rads and a hydor l30. Trying to get it stable at 4ghz now for 24/7. How high can i push the voltage for 24/7 use on that water setup?

[m411b]

Dont know if it has been posted or not but my 0924BPMW unlocks perfectly with the MSI 785GM - E65; obviously there is no tweaking done yet as I just unlocked it but rest assured it will get pushed!
