I have a Phenom 9950 Quad-Core, with windows xp. As I read some time ago by the Internet, said that XP could only pull 2 processor, so do not take advantage of the Quad 4. The issue is that if I go to device manager, I get the 4 processors, but if you step on Everest, and still the route processor CPU Properties - processor type, I put 2x, 2600 MHz, so do not understand that if only recognizes 2.
Conversely, if I look a little further down, in particular ---- Processor CPU usage, what I see is:
CPU # 1 / Core # 1
CPU # 1 / Core # 2
CPU # 1 / Core # 3
CPU # 1 / Core # 4
and beside each, a figure which rises or falls depending on the CPU usage.
Are you using Xp or not the 4 processors? Be better with Windows Vista?
Thanks to all.
