i change the EC mode to hybrid and set the ACC to auto, it comes up with the 'updating firmware' message, then turns off. but doesnt restart, and when i hit the power button to turn it back on, nothing at all happens. its only when i take the power cable out of the psu and put it back in i can turn it on again and everything runs as normal with the EC and ACC as i left them. windows doesnt seem to recognise any changes in number of cores though so im thinking that the 3rd and 4th cores are faulty? or the psu cant output enough power?

cpu is phenom X2 555 BE and motherboard is Gigabyte 880GM-UD2H rev 1.3

Right, i reinstalled windows and now both cores have come up again so thats all good. but still unsure if i even can unlock another two or whether its just a dual core.

the bios looks like this:

should it say core2 and core3 enabled/disabled under core control or does the lack of it mean i dont have the other two cores to enable?

Core unlocking is not guaranteed to unlock, The cores are disabled for a purpose. But some are just to full the gaps in the product range.

Try these steps once at a time.

1. Add a little bit more voltage to the cpu and change EC firmware to hybird and enable ACC, Then restart.

2. Lower the multi and HT multi with added volts and change EC firmware to hybird and enable ACC, Then restart.

3. Change EC firmware to hybird and enable ACC, and disable core0, or 1 Then restart.

If them steps fail, You are one of the unlucky ones.
 
EC firmware = hybird
CPU core Control = manual
advanced clock calibration = all core's
When bois restarts switch off PC at plug for 20sec's then boot.

Dont change the voltage just try to boot into windows. it if fails in CPU core Control turn off core 2 and reboot it it still fails in CPU core Control turn on core 2 and turn off core 3. if it still fails then what you have there is a dual core.

My 560BE will only unlock to a tri core because core 3 is damaged
 
well tried everything above, nothing. the only options for cores 2 and 3 are in the ACC bit. nothing else comes up in cpu core control. has anyone got a picture of their same bios screen so i can see what im supposed to have there?

failing that, i guess if i want more speed im guna have to OC. cheers for the help though guys
 
core control just has auto or manual, so i can enable or disable the core1 (in the image above)

and ACC has auto, disabled, all cores or per core, and can change the percentage of the 0-3 cores showing.
 
Is that the latest BIOS there. When I tried unlocking mine, (a different Giagabyte) I couldn't see core 2 & 3, updating the bios it appeared straight away.

You can supposedly try Tri core if quad fails. I could unlock mine but it wouldn't boot, even when it was unlocked but had both extra cores switched off.

The Gigabyte Windows based overclocking tool lets you unlock cores, maybe you see if that will work for you.
 
NOT ALL CPU'S UNLOCK

if you did as i told you to and there was no extra cores then you have a CPU that was made as a dual core.
