I got a phenom II X2 550, a gigabyte GA MA770T UD3P mobo, 4 GB G.Skill DDR3 1333Mhz ram, and a Sapphire ATI Radeon HD 4850 graphics card for my new build. Having read about the numerous successes of unlocking cores, I really wanted to do it. But I had fears of breaking the processor or motherboard, Yet I still did it the same day I built the PC. I updated the bios to the f2c version, went into the MB Intelligent Tweaker (in the bios) changed EC Firmware Selection to hybrid, and set the ACC to auto. Then I saved the settings and exited. A message flashed that said "UPDATING EC FIRMWARE, DON'T TURN OFF OR RESET SYSTEM!" Then the computer turned off and after about 5 seconds turned back on. Windows 7 and XP both said that the processor was a Phenom II X4 B50, and so did any other program or utility like CPU-Z. Windows 7 gave it a score of 7.3 and as a dual core it was 6.5 I ran 3DMark 06 and it gave the processor a score of 4730. As a dual core 3DMark gave it a score of 2674. So when all 4 cores where unlocked it was working almost twice as good. It was Prime95 Stable and overclocking this thing was a breeze because it's a black edition and has an unlocked Multiplier. But be sure to get a good cooler if you plan on overclocking it.

(The scores above were all tested on stock speed 3.1Ghz, when I overclocked this CPU the scores were soaring higher than the sky.)

Conclusion: I bought this CPU for $102.99, but the performance I got in the end was worth way more than that. I basically got a phenom II quad core black edition! For the price this is the best CPU you can get!

Where do you find the batch number? If it's on the CPU itself, then I don't know because I didn't read what was on it. And it's already installed. Maybe when I'm going to buy a new cooler I'll check and if you will still be interested I'll post it up.

Idk, I've read a lot of people are having success unlocking cores on this CPU.

It overclocks even higher then what Tom's could do it?!? Nice...I"ll try it, stress test it, and benchmark it. Then I'll post up what I got...

Sorry about all that...here it is:
Everything is @ stock except CPU...which is overclocked to 3.2 to match the 955 speed...

I think I can hit 3.5Ghz...but I think I'll have to give it a voltage boost...is 1.4 ok?

I see...well I got all cores unlocked and I managed to overclock to 3.5Ghz stable :D
My voltage was 1.4
I'm sure I can hit 3.6 and make it stable...I hit 3.8 and it was stable enough to boot windows and run 3DMark06 benchmark...the scores were incredible.
I'll post up a screen shot later, I'm reinstalling windows...

Nice ;) ;) ;) ;) ;)

BTW make sure you monitor those temps at 3.8Ghz, don't fry it !!!! :eek:

What's up with the lock-ups? Mine booted right after the build, I've had no problems with it at all so far...
Can you explain exactly what happens with yours?

Yeah I kept it at 3.8 just for the benchmark...to see how high it goes.
When I get a better cooler, I'll leave it at 3.5 or 3.6 (I always like setting a little lower than the max)

Currently...
I put the computer right in front of the air conditioner vent to keep it from overheating on 3.8

I would not do that, if anything condenses (gets wet) you can do some serious damage to your hardware. I have a 30.00$ cooler on my 550 and at 3.5Ghz it never reaches 50c (49c MAX). When i buy the CPU the first thing I do is throw the stock heat-sink in a box i use to keep all my old hardware and install an aftermarket cooler. IMO stock coolers are a piece of junk unless you plan on not doing any overclocking at all.
