No socket 775 processors that are quad core have hyperthreading. There are also no eight - core socket 775 processors.
You misread it.
Or there was a bug.
Or you have a LGA-1366, LGA-1155 or LGA-1156 based quad core not a socket 775 based processor. And when the BIOS reset it automatically turned on
hyperthreading which allows each processor core to act as two logical cores (which many 1366, 1155, 1156 processors HAVE) which causes there to be 8
logical cores, 4 physical.
Or you have a dual socket LGA-775 based system (two physical processors) with each processor a dual core with hyperthreading. When BIOS reset it
automatically activated hyperthreading.
Or you have some server setup that I'm not familiar with.
For best performance, enable hyperthreading. Also if you think your 4 core was actually an 8 core, then you can take the IHS off and check (this will
destroy the CPU btw) by looking at the physical die underneath the Integrated Heat Spreader.
