vista64 only using 1 core of my pentium d....? bios counts 2 ?
a few weeks ago i noticed a performance drop with vista 64 so i had a snoop around in task manager checked unwanted services etc only 2 notice it see's 1 cpu core for my pentium d 2.80 ? ive tried a re-installing and un-installing the cpu in device manager with only 1 core installed each time even thoe it knows what cpu model it has installed ? ive checked the bios which has 2 cores counted, ive even updated my bios anyway and tried re-installing in device manager again, ive also updated my chipset drivers no luck there and ive googled away all day 2 find a solution but all i get is amd vista problems ? ive tried scanning for hardware changes the lot and i can not find any updates from micrsoft and asus(mobo) about this ! any help would be much appreciated ! cheers! asuse p5vdc-mx 2 gig corsair pc2-4200 ddr2 533mhz pentium d 2.80 ati agp x1550 need anymore info please let me know -- jay22 |

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.
