X2 550 Unlocking & Overclocking Consolidated

[nguyenquochuy]

Oh, and hmmm what is the safe voltage for the x2 550's? i had mine at 1.425v at 3.7 unlocked stable. Do you guys think that is ok to go over 1.5v on air 24/7 (main rig) cooling is zalman 9990 idle at 32c full load 47-50c.

more than 1.5V on air seems to be high for 24/7 running, but 1.425 should be OK

[Tom128]

The voltage itself is not too bad, Phenom II's can probably take 1.5v-1.55v safely for 24/7 use. The issue is keeping them cool at that voltage, best below 55c load which is where it seems stability starts to nose-dive for me anyways.

Heat is the killer. I ran my x3 at 1.5 for two months with no issues but I have great load temps. As long as you can keep your temps in check, I wouldn't worry about 1.5v vcore. You might not even that much voltage unless your going for 4+ghz

cool, thx for the quick responses guys.

c_buzz can you please add me to the list? Thanks.

Has anybody figured out how to get core temps on a unlocked 550BE?

[cdawall]

semi-worked one of the cores is bad and will only clock to 2ghz

Anyone successfully unlock x2 550BE on a GD70?

[FrOzE]

Manage to unlock to 4 cores.. :P

But very very unstable...
Temp shot up to 71C once all 4 core unlocked...
Using 1.44B bios..

Btw.. i'm using default cooler.. Fellow members who unlock all 4 cores n stable.. u guys using default cooler or?

[Team Vernia]

I'm using the default cooler too, and the temps hit about 71 like you said. That's the cpu temp and not the core temp, though so I'm guessing the cores are hitting about 63 or so tops (about 8 degree difference when running two cores). AMD lists that the processor can handle up to 70, so hopefully with an aftermarket cooler I'll be able to run this at 4 cores.

Hi

I managed to unlock my 550 with a M4A78-E using bios 1104. In my previous post I wasnt able to do this but its very unstable I get graphical glitches.

I did manage to run prime95 and all cores seem to work ok. Im sure its just a bios update for this motherboard, Im emailing ASUS as we speak to see if they can rectify this problem.

Mind you, Its took 3 emails to ASUS as they dont know how to enable or find the unleash mode!!

Sounds painfuly like my experience on this board

C-Buzz.. i think u got my info wrong
It's MSi 790FX-GD70 - 1.4b4 BIOS - Success

Btw.. anyone can recommend a good CPU cooler?
U guys using default coolers or?

Yeah not sure how that happened I refuse to use that sad looking stock cooler. Here is my modified S939 Opteron cooler:

Isn't your system unstable with all cores unlocked? That doesn't really classify as a successful unlock

[FrOzE]

Oh ok.. then u can put it as partial success :P
Any way the mobo model is wrong too..

Now gonna source for a good cooler to make it stable.

It's quad prime/linpack screenshot or fail

Hello.
My 0922APMW code 550BE
Air cooling

Is this the latest bios? Did you try with 3/6/2009 and failed to unlock ??


I just found out that a new bios is out 2009-06-17

[FrOzE]

After trying for a couple of times, finally got the extra 2 cores stable. The reason y last time it was so unstable was becoz of the extremely high temps (idling in BIOS was @ 70+C).

A very very big thanks to Jingz83 for loaning me a True 120 and AMD brackets. Now finally got it stable. Now wif slight overclocking. Gonna try higher later....

So far my 1st ever AMD journey is quite successful :P

[FreeRadical]

Anyone tried this on a Biostar TA790GX XE? That board has me intrigued. SB750 on mATX? (we don't get Jetway and DFi here )

[FrOzE]

There's a new batch 0922CPMW.. anyone tried this batch?
