Hello, I have disabled cores in my i7 cpu (running on an Asus p6X58D with Win7) so I could play an older PC game. I did this in the bios, selecting 1 core rather than 2 or all. So far so good.
But, game finished, I went back into the bios and selected all cores. No probs. But running core temp showed only 1 core. Msconfig-boot-adv options only shows 1 processor. But device manager shows all 8 cores present.
I have updated to latest bios, uninstalled all cores in dev manager, to reinstall at boot, but still I can see only 1 core present and working.
Is there a registry setting that I could check? I seem to have tried most of the things suggested in forums.
More aboutonly core
Download cpu-z to see how many thread/cores are arctive.
check device manager again. see if all the cores are there.
