Phenom no POST after clear CMOS
Well, well. My Phenom did not POST for over 24hrs. This is very abnormal, I was about to return it because this is the exact problem my older BE had and I really do get sick of it. I wonder why this occurs?
None of the 9500/9600s had it though on the same board with the same BIOS. I had phoned my uncle to drop it off Saturday after trying everything which usually worked with the last BE.
The error started when I chose 1066 mode. It failed POST, so I had to clear CMOS. That's it, after that it was stuck in a reboot loop.
So how was it fixed? Ironically, you had to go subzero AND take the chip out of the socket and reinsert it to fix it. Stuck the chip under -20C ice in a plastic bag inside a tub within a -31C refrigeration unit. Booted without HSF on, and here is the IHS temp after the first successful bootup at ambient 27C (HSF still disconnected):
Yep, it took roughly -10C - 2C BIOS temps to boot it up and that's when it was coming back to ambient. After that I could reinsert everything but using AMD stock cooler, I haven't put any more paste on it and now the stock temperatures are 8-10C higher.
Achim: Ganged mode is fastest for single threaded applications and unganged mode is fastest for multi-threaded applications.
Here's Ganged Vs. Unganged mode at stock (little tweaked timings for you to compare). AOD button = Red.
