Hey guys,

As in title, the computer only seems to run on one core. Bios is updated to latest version. Here's the computer:

---------------****

Operating System
Windows XP Professional 32-bit SP3
CPU
AMD Phenom II X2 555 33 °C
Callisto 45nm Technology
RAM
4.00GB Single-Channel DDR3 @ 669MHz (9-9-9-24)
Motherboard
Gigabyte Technology Co., Ltd. GA-78LMT-S2P (Version 3.1) 36 °C
Graphics
VA1912wSERIES (1440x900@60Hz)
ATI AMD 760G (Gigabyte)

---------------****

I tried playing with settings in Bios, including unlocking the CPU so you could see the four cores. The PC then recognised the processor as Phenom II x4 555, but still only sees and uses one core.

Any thoughts?

You need at least XP sp2 for multi-core support I beleive.

Hey,

Yes it's running XP SP3.. so it should be able to recognise the multi core. Any other thoughts? :)
