Greetings to All,
I have successfully unlocked my Phenom II X2 550BE.
I think I may be one of the really lucky ones because I am running at just over stock speed and UNDERVOLTED. (CPU:3.4GHz, 1.2V, NB:2GHz, 1.2V), and system is rock solid and in the low to mid 20's in Deg C. for both CPU and chipset (at idle). It actually runs cooler since I installed the modded BIOS and even cooler since unlocking. Is that normal?
Windows, Speedfan, CPU-Z and AMD Overdrive all show 4 cores. I have run prime95 for about 2 hours with no errors before stopping it. Temps never reached higher than 38C for CPU and 27 for NB. I then burned it in for about 48 hours. Still no problems and that was about 6 months ago.
Most people seem to require underclocking and/or overvolting. Am I just one of the lucky ones?
