X2 550 Unlocking & Overclocking Consolidated

[Tom128]

Also, one more question. i see that the X2 550 has a Hyper Transports of 4000MHz. In bois it's set to2000mhz, so should i change it to 4000mhz in bios?

2,000Mhz HT = 4,000Mhz effective. That's the correct setting

Side note. I just went a bit purchase happy. I got the UD3P and a stick of DDR3 to see if I can unlock the 550. I also purchased a BIOSTAR TA790GX XE and will see if that unlocks (assuming I get a chip that unlocks...). I needed another mobo anyways for a cruncher, might as well get some testing done at the same time. Saw a few reports of that board unlocking 720BE's.
