Bios Mods -The Best BIOS Update and Modification Source

Hello guys! My case seems to be "simple".

I have a Kazuk (Brazillian brand) LGA1156 with H55 Express chipset mobo. When upgraded my CPU to X3470, only 2 cores are detected by the BIOS. This mobo have an AMI BIOS, and I've added some microcodes from others manufacturers (06E5) and flash, but without success.

OBS: The system boots normally with 2 cores, but when set to "ALL", windows/ubuntu crashes at boot screen.

Someone can explain how to unlock 4 cores on that BIOS?

Image from BIOS is attached.

All help is greatly appreciated Big Grin

Thank you for your reply.

Can you boot in Windows with safe mode and ALL cores in BIOS?

No, I can't boot in safe mode with all cores. Same as before, windows logo appears and reboot Sad

Make a screenshot of regedit with expanded key HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0

Done.

BIOS already has suitable microcode for this CPU.
Do Load Optimal Defaults, save and reboot.
Then try to boot Windows in safe mode.

Same behavior. Sometimes freezes without restart at windows boot screen.

ALL CORES (Load Optimal Defaults) + Safe Mode = Restarts or freezes at boot screen;
1 OR 2 CORES = Normal boot.

Try to use Windows XP Live DVD/USB
