Core 2 Quad missing 2 core

Hello,
After changed my Pentium 4 to Core 2 Quad Q6600, I notice that I only have 2 core and 2 thread instead of 4 core 4 thread.


CPU-Z

View in Task Manager also show 2 core instead of 4 ( http://i.imgur.com/iCEAC.png )

CPU and MOBO info : http://pastebin.com/P2ygihHm

I have tried :
Reset CMOS
Enabled 'Multiple Processes" in BIOS
MsConfig (Untick "Number of processors" but at there show only maximum 2 core only)
Uninstall the Intel processor driver in "Driver Manager" and restart computer

If anyone knows how to bring my missing core back than please help me


EDIT: Problem solved by changing the mobo that support C2Q

    The BIOS on your motherboard will need updating to support the CPU. Normally the system would not boot at all but if your board will support a Core 2 Duo then that may explain it. The chip you are using is two Core 2 Duos on the same chip and sharing the cache so the BIOS still sees it at that level. To get it to see the chip as a "Quad" or in this case two Core 2 Duo CPU's you need to update the BIOS.

    I found out that my motherboard brand is 'ESonic' and I can't find the motherboard model and it seem like they don't have any official website at all.

    But there's a sticker with the word "945GCFBBL"

    The design similar to this


    Can we mod the BIOS or use any trick to enable the quad core?
  3. You need the BIOS image that supports that specific board. If you cant find one you will need to find another board. I dot believe that there is a trick that can circumnavigate that degree of architectural incompatibility.
  4. LOL are you running windows xp?Xp only suports 2 cores...
  5. Nope my bad hes running win 8 pro (blech).. Ya good luck finding a bios for that but ya prob just needs an update..
  6. The chipset doesn't support it. check out compatible products on the left.

    Wrong. XP Pro supports two physical processors, not just two cores. A quad core single CPU would work on XP Pro just fine. The problem is that his board doesn't support that chip.

    Not sure how you cam up with that model of board. The board you linked is a socket 478 board. Completely wrong architecture. OP is using a 775 CPU.
