Hi,

Has anyone succesfully unlocked the new Phenom II x2 555BE? Do i use the same process as unlocking the 550BE?

If anyone has, please post your stats here, and the process used.

Hey Starges. I haven't done the 555, but I did a 550 for my brother, and recently the 720 for myself. The process for those was identical. Here's how I did it:
Enabled ACC
Set "Hybrid" mode
Set "All Cores"
Set "0%" adjustment
Save Settings and Exit

Once the BIOS was done doing whatever it does when the warning message flashed, the system rebooted. The 550 was then ID'd as an X4 B50 and the 720 was ID'd as an X4 20. I let it boot into Windows, loaded Task Manager, and verified 4 active cores. I then Prime95'd 'em with a Small FFT torture test while they were set to the default clocks and voltages for several hours. 5 hours went by and I was satisfied the 4th core was stable, then proceeded to overclock it.

Wow.. good for you!
Didn't know the process was that simple.

Looking forward to trying out with my 555BE. I ordered it online and its bound to arrive in a few days. I read somewhere that unlocking the cores is a 50/50 chance, no guarantees.
Hope it works for me with this specs:

ASRock A785GXH/128M Socket AM3
Super Talent DDR3-1333 2GB (will upgrade later)
Thermaltake TR2 600W
Seagate ST3500418AS 500GB
Saphire ATI Radeon HD5770

Just read your thread, did you manage to OC it and what benchamarks did you get? :o 
March 25, 2010 1:13:28 PM

Don't need to OC it now. Benchmark improved quite a lot on Everest, mostly on top 5. Crysis running better than ever.

Dude, i am so jealus. :pt1cable: 

Can't wait for my shippment to arrive and unlock that beast... :wahoo: 

BTW, what gpu are you using??

I'm using a beautifull Gigabyte HD5770 1GBDDR5, 128bits.
edit:man, you got ~the same card :D . You won't regret! What resolution are you using?

I have an old 17'' crt monitor (i know... [:thegreatgrapeape:5] ) so for the moment i am running at 1280x1024

5770 Rocks..... [:lectrocrew:6]

Have you updated to 10.3 yet?

That mobo is known to unlock extra cores. Hope you get a good unlockable CPU.
I believe the chances now are more than 50/50 since chip yields for Phenom II are better and even good cores are locked by AMD just to fill in demands for dual or tri core.

Welcome... I myself have an unlocked x3 720BE OC's to 3.6Ghz running for 3 months now and have undergone brutal OC attempts up to 3.8Ghz and 1.56v ( but not stable there ). So definitely I will not be one of the naysayers of unlocking cores...
March 25, 2010 4:07:50 PM

Also as you may have noticed i have 2gd of ram. Will that in any way bottleneck the performance of my 555BE or 5770 when OCed?

What coolers do you reccomend? I've heard some great reviews about these so far:

http://www.corsair.com/products/h50/Default.aspx

http://www.zalman.com/ENG/product/Product_Read.asp?idx=...

Though i have to say am really liking the Corsair H50 [:lectrocrew:5]

I don't know about the H50 as I never looked into it...

Zalman is not bang for buck... it is fancy and nice to look at but a Xigmatek Dark Knight beats it in terms of performance and easy install ( no need to take out motherboard from the case ) and its not bad to look at too. I'm quite is a hurry so can not give the link rightnow. Search for Frosty Tech Review on these coolers. If you just care about performance and willing to go to great lengths to install it ( removing motherboard from the case ) then best bang for back is Cooler Master Hyper 212.

No it will not bottleneck. It is easier to attain higher OC with single stick of RAM than more.

H50 coolers do a pretty good job, and they're quiet. But you can get HS/Fan coolers that perform as well or better.

Whenever I'm on the prowl for a new cooler, I always hit up Frostytech
http://www.frostytech.com
They review new coolers often, and have an archive of well over 250 coolers for comparison, all ranked according to performance and noise. One of my favorite pages of theirs is the Top 5 page.
http://www.frostytech.com/top5heatsinks.cfm

You can go through their reviews and tests and find inexpensive gems like Evercool's Buffalo or Akasa's EVO120. (Which sell for ~$15 and cool sub-125W CPUs very, very well.) I have two Akasa EVO120's - one on a 95W 7850 BE (Kuma), the other on an old X2 5000+ BE (65W). Both are OC'd to ~3.2GHz, and neither ever breaks 43C in Prime95 with the fan at 100%.

No, I'm using 10.2. Thanks for the heads-up! A lot! I too have an old 17" CRT :D

Here is what I got out of my 555be so far.

OMG. That's almost 4 ghz!
March 26, 2010 9:59:14 AM

And its completely stable at 3.92? .... Geez!

It took a while to get it but it ran prime95 for 1 hour at maximum heat. I have it overclocked in the bios. After I boot I can run AMD overdrive and change the multi on cores 1 and 2 to 20 and get 4 GHz on just those 2 cores stable. You can see that CPUz shows at 4GHz but cores 3 and 4 are still at 3.92GHz. So Im running 2 cores at 4 and 2 cores at 3.92 stable.

Thats amazing dude! [:boudy:2] Must me one heck of a cooler you got there.

Let me know how high you reached, and post some benchies for me. [:jaydeejohn:5]

I have a 550BE running 4 cores at 3.55GHz @ 1.3875V (17.5 x 203) which runs Prime95 temp @ 49C max. This is the max I can get @ 1.3875V and any voltage increase increases the temp by nearly 10C (using hyper TX3) what temps are you guys getting higher clocks running?

I have a 555BE. only was able to unlock one core, other one was defective.

well still paid dual core price for a tri-core :)  right :p  i just like building pc's and seeing how far i can OC on just air and the unlocked cores i just see as a "bonus"




thank you AMD lol

hey so what voltage did you kept for the cpu..can u guide me through the same.Because i tried unlocking 2-3 times bt it goes unstable like a splash screen kind of effect for which i need to restart my pc
