ASRock M3A785GXH/128M

[imamage]

Just have it in stock in Hong Kong
The layout look similar with the M3A790GXH , but offer at cheaper price at around $700 HKD (~$90USD)

I got a Phenom II x2 550BE (0923BPMW) last month but haven't time to try to pair it with DDR3 RAM. Since it's my payday, I finally get a pair of DDR3 RAM (Team Xtreme DDR3-1333 , Micron D9JNM chip ) and M3A785GXH/128M board to have some Fun

The board is pretty nice with all usual I/O ports ( eSATA , IEEE 1394 , HDMI , VGA , DVI etc)
3x PCI-e x16 slot ( x16 + x4 from SB ) OR ( x8 + x8 + x4 from SB)

Air cooled by AMD Stock Cooler from my Phenom II x4 955BE package :D

The Max point that CPU-Z can Validated , CPU cooling equipped with AMD "Stock Cooler" from my 955BE
It seems 550BE overclock better than my 955BE

Have you ever tried to 'unlock' other 2 cores of 550BE? Can this mobo unlock it?

I am having a hard time to "unlock" my 550BE with this board
When I enable ACC function in BIOS , either it doesn't boot up
or it boot up as Dual Core

Tried L3 Allocation trick but it's the same

[superpyton]

When I enable ACC function in BIOS , either it doesn't boot up or it boot up as Dual CoreIf it boot as dual core, try "soft" reboot (with Menu Start->Reboot). I have same issue with M3A780GXH/128M.
Could you show some HTT overclocking on low CPU multiplier?

Sure thing
Just give me some time :D:D

EDIT : Sorry dude , it seems the board Southbridge having problem, I can't install Windows with it (keep showing BSoD)
I guess I have to take it back to the shop for RMA

Well , before the board DOA , here is some memory overclocking test I done.
