good news but at first the story of my Phenom 2 X2 550 0919 EPMW :

Motherboard : ASUS M4A78-E DDR2 790GX & SB750

Original bios : 0711 ..... unlocking : failed (black screen and reboot again, again and again .... when ACC is enable)

Bios 0082 modded : unlocking failed (when ACC is enabled, it's the same like 0711)

other try with bios from ASUS give me the same results : no boot

Bios 1204 : unlocking failed (when ACC is enabled, it's the same thing like 0711)

last try : bios 1210 (the last on line), I put the multiplier on 10, raise the vcore @ 1.50v but decrease the HTLink to 1600 MHz). I enable the "special" "unleashingé mode with ACC and try a boot.

Hmmmmm the PC boot but i have not see the post. Arrived under Vista, a little CTRL + ALT + DEL and i see ........... 4 active cores

A big YES !!!! I'm not sure : it's the last bios or the HT Link set to 1600 MHz but there are now 4 active cores.

I try 3200 MHz with 1.50v and it's stable. Maybe i can decrease the vcore but i'am now interresting to overclock my new quad core that cost me 85 €uro!

Sorry for possible mistakes, my english is a little poor
wow!!so high vcore!! carefull as that is the max vcore. 72degree i thinks max temp for x2 550. try to lower 1.4 for daily use as i can get 1.15vcore x2 3100mhz. x4 3400mhz for 1.35vcore
