no im sure, it also shows up as 1 in divice manager and ive used cpuz which has 1 core showing plus there are no options in task manager to show both cores in 2 graphs its just not being used by vista ? -- jay22

is the 820 not a hyperthreading cpu? that's not a real dual core.

no its not hyperthreading it dos have to cores and when i had xp it was installed as 2 cores or 2 processers i tested on cpuz in the past and it counted 2 cores also but it does not now 4 some reason? ive hard of the same problem with some amd processer which was fixed with a patch 4 vista 64 but no 1 seems 2 have this problem with any intel chips im sure its a vista problem my bios counts 2 cores !:sarc: -- jay22

Even if it were only hyperthreading, he should still see two logical
processors on the performance tab. If he had a hyperthreading dual-core he would see four logical processors. Only if he has a single core cpu w/o hyperthreading should he see just one logical cpu.
