I installed the latest BIOS upgrade for my board (1015), and, despite my specific instructions to the contrary (by way of unchecking the checkbox for the same), ASUSUpdate cleared the CMOS checksum, and reset all of my BIOS settings. I shan't bore you with the details, but when I put everything back to where I thought that it was, it would reboot on entering Windows, as if it was overclocked too much. After much tinkering, I realised that the problem would occur whenever PAT was enabled, and would not occur when PAT was set to "auto" in the BIOS.
Although I cannot now remember for sure, I think that PAT was set to "enabled" before this latest BIOS upgrade. Even downgrading to 1014 did not help. I am somewhat confused as to why, even when I set my CPU to stock speeds, PAT should cause such severe instability. I thought that it might be SNDS, but since I can get it to overclock to just as fast as before without PAT on, and since PAT causes the failure even when significantly underclocked, I doubt that this is the case.
Does anybody have any ideas? They would be most welcome.
Specs below:
P4C [email protected] (250FSB, 1:1; 34C idle, 50C load; default voltage)
OCZ Gold dual channel, 2x 256MB (1.85v, active cooling)
Asus P4C800E-Deluxe
Windows XP Pro SP1
