X2 550 Unlocking & Overclocking Consolidated

3.8ghz 0921 apmw GA-MA790FXT-UD5P F3K

Thanks, but am looking for a max 45w, due to 24/7 use. Less power bill

Athom II x2 250 is natively dual core, 45nm...there is no CPU for such a socket and performance w/ less power demand..

And it should overclock great, in the other side it can be heavily undervolted, for stock clock.

Yay, finally got a couple of different steppings to try..

2 x 0922APMW's, I'll be testing them Monday/Tuesday

Same as mine, did you get it from newegg? I ordered another and they sent me a 955BE by accident LOL. The chip should clock good, at least mine did.

good luck, I won't be able to check your results for a while, I 'll be on vacation this week. But hope they do well.

Nice work, now crank it up & lets see some 3d action

good luck, I won't be able to check your results for a while, I 'll be on vacation this week. But hope they do well.

Thanks, luck is exactly what I need Hopefully these newer steppings have more potential.

Do we have anyone else with 0920 results? Or am I the only one

yap, i got it from newegg. so far, now is 3.7ghz stable on stock fan and voltage but the stock fan and temp is killing me....

ya, that will hold you back...3.7 isn't bad tho considering.

Hi guys,

I've just bought one, it's 0922 APMW, the same stepping as lamby_splendid have (well, it's not like I have much choice, in Indonesia most of the X2 550's are 0922 APMW stepping )

- X2 550 0922 APMW
- ASRock M3A790GXH/128, BIOS P1.10
- G.Skill PC12800CL7-2GBHZ
- GELID Silent Spirit HSF

BIOS all Default, just change the ACC to AUTO, and set the DDR3 freq n timing manually, and...voila! 4 core unlocks , lucky me

and a little overclocking from AMD Overdrive, just change the cpu multiplier to 17x, all voltage are still default..

Unlocked 4 Core, 3.4Ghz, Linpack 32-bit 10 min START

nice run lucky_noob..!

lucky you have there alva..
wonder how much the board cost?
it's interesting that you use that board

Hi mate,

The board costs roughly 130 USD, pretty much the cheapest AM3 board available in Jakarta at the moment, and since I'm REALLY low on cash, I don't have much of a choice..

* well, I probably should just buy a cheap AM2+ board, but I feel like getting an AM3 one *

Nice to see you had a sucess..(wife brought her laptop so I can post LOL).
I just checked the list, look like a lot of 550's doing good.

[gOtVoltage]

I will say if you have a steppiong Above 0921...it more than a 50% chance you will have a great X4.


Best budget chip ive ever used.

[charged3800z24]

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Wow ! .. That's another way of having 4 cores "unlocked"

I know, I called and told them they sent me th wrong chip and offered to pay the difference. The lady said "keep it and we will send you a promo code $10 off your next purchase for your inconvenience". I must say thoguh, the 955 does clock higher with less volts when going for stable.

Got a 550BE 0922APMW today to go with my GA MA790X-UD4P.Waiting for my new memory and HDD which are coming Wednesday.
How high do you think I can push this 550 with a lapped Arctic Cooling Freezer 64 Pro?
I had my 3600 Brisbane at 3.1Ghz full load 47c

Well I had my 550BE 0919EPMW at 3.8GHz (200x19) at 1.4V, the load temps when running prime were around 45'C. That was using the same HSF as yours (lapped also) but my case has 4 120mm 60CFM fans which shift a fair bit of air.

What I found with my chip is:

200x18 @1.3V (stock volts) = ok.
200x18.5 @ 1.35V = ok.
200x19 @1.4V = ok.

So I needed 0.5V more per 100MHz step after 3.6GHz. (This was with all other voltages at stock, NB, CPU-NB, etc)

Good luck, hope your CPU unlocks to 4 cores and is a good clocker
