So about 6 months ago i unlocked the 4th core of my X3 PII 720 BE and ran it on prime95 for around 16 hours without a problem. Today i noticed however i dont have 4 cores in the performance tab in the taskmanager. I exit to bios and sure enough unleashing mode is enabled and set to 4 cores. I Disable it, and restart. 3 cores in the performance tab. I re enable it and restart, still 3 cores in the performance tab. I did a google search but cant find anything on this at all. Could my 4th core of burnt out? I Usually never leave my PC on for more then 2 days at a time, and even then very rarely.
So i just reset the cmos, got the message at the beginning went in and set the correct timings for my RAM and let it boot. Looked, 3 cores. Restarted when in and turned on ACC, unleashing mode, per core, -2%,saved and exit. Looked again, still at 3 cores.
Also apparently having your PC time reset to 2050 will make it so you cant sign into ANYTHING, like gmail/youtube/ and toms hardware.
