Windows Server 2003 and Quad Processors

Anyone know why Windows Server 2003 shows my Quad ML 570 and DL 580 servers having 8 processors?

This is because of Hyperthreading.

hi david

hyperthraeding means, that each physical processor has two internal logical processors. this gives you twice the number of cpus (logically).

hyperthreading can boost the performance of 1 and two processor systems by 10-30 percent. with higher numbers of cpus you might have negative performance effects.

you can simply enable/disable hyperthreading in rom baset setup (press F9 after post - you will be prompted).
