Help me stabilize my X2 550 unlocked.

Yes I've already tried this, no good

What is the Temps Stock with X4cores enabled?

Are you watercooled or using the Stock Air cooling on each chip.

If its the stock ALUMINUM heatsink, it just may only be good for 2xcores Not 4xcores.

Thats the only thing i can think of.ATM.

Bois temps are normal around 30c with 4 cores enabled at stock speed. Using an Opteron heatpipe cooler.

They are definately not overheating.

what about full load? These chips prefer "cooler the better". The dual versions are most likely not going to OC as well anyhow. Takes more tweaking.

I can't get any of them fully loaded, they all have issues...

I can guarantee they are not overheating that's for sure.

Got my gigabyte GA-MA790FXT-UD5P today, one of my cores is dodgy to

stepping is 0919EPMW.

How can you disable a core? is it possible

Bummer. I don't think you can disable cores as far as I know. You can set affinity to select which core's run the program, but as far as disabling a core altogether I don't think it's possible. Your stepping is even earlier than mine. Mabye the later steppings are the one's

mybe phenom II 550 have bug in quadcore, because is very high risk to unlock 2core to 4core

cant get mine stable, tried lowering multi on core 0

Same issue as some of mine. Any stress & fail instantly. If you get it stable be sure to let me know

Hey,, try setting yur Nbvid to 1.25 - 1.3vid... After 3800mhz you will need to run at least that to clock all four cores.

Also it would be good idea to see how High it clocks with Two cores and high NB with 1.3vid on the NB.


1st,,
Clock it as high as you can X2cores then lower the CPU and Nb while keeping the Same volts used with the Max Oc you found in 2xcore mode.

2nd,,
Enable Hybrid option with say 3400mhz to 3600mhz/Nb@2000mhz ( mine does this with Stock volts)on all four cores,

slowly raise the CPU with NB @ stock ,@3800 with Vcore @ 1.44/1.48 and NBvid @ 1.3v it should be more stable than if NBvid was @ 1.1v.


Gonna see what two cores will do soon,, I usually would Clock Two cores first(How i did the 720) ,but was excited as Hybrid enabled all four from the get go.

Mine clocks best with Low HTT and using 20x CPUmulti to get up to 4200mhz Max in TwoCores ..After a lot of Hangs in 2xmode i just went back to Fourcores @4160/2700 with 4xcores in hybrid now.

It seems harder for me to get Two cores as stable vs 4cores.

I Know its Bios related and Not the Chip ,r my Chip would not Be able to Bench at 4160mhz.

This is with the Dual Bios Function (Normal vs Hybrid)and the Normal Mode seems harder to tweak. I think the UD4P F5a Bios is better optimized for Hybrid Mode.

Dam u & your l33t processor

I rang up about 8 different shops around Au today to try find 0921, but every single one was 0920 GPMW

Well that makes Two of kind for the Same stepping with X4 3800/2800 or better.


I wonder what (Charged) has,, he should have one today too. He ordered from the EGG i think. Thats where mine came from.

Mine is on its way, my wife is going to call me and give me the batch info. I am still at work and will being hitting the Gym afterwords. So, it will be around 7:00pm EST before I can play with it But I will definently push it tonight.

Oh man thats like 5 hrs away, I dont know if I can wait that long to see your results......

Good luck tonight, come on batch number...I bet your fingers are crossed

Well, wife called and here is my CPU

CACYC AC 0921APBW

I will let you guys know tonight

ooooO thats a new one.

whats your your last five on the serial# mines 90020.

I see XSmadness forming with these things.

[i found nemo]

and ppl say it's not worth it to try and unlock cores!

c-buzz i still think it's cache related or mobo. u have to try another mobo, it's the only thing u haven't touched! just imo.
