Well when switching to slower ram you will likely get the triple reboot so it can load a reasonable Auto setting for the ram. So it is normal
Your PC will survive the restarts, dont worry!
And yes, could be faulty still, that STOP 0x0000007E is a ram error
Vista's tests sucks.... Oh I said that once already, J/K Run memtest86+ and see what it says about it
Not sure what you meant there about the Disk setting, SATA Port0-3 should be enabled for XP/Vista
It will be fine to test on that machine, just easier to know if it is your settings or board if you can test on another machine. but either way could be incorrect settings if you see errors anyway. If you see errors with the above settings then your ram is indeed showin gerrors as those are very loose timings and should not fail at all.
When I said P45/43 are the same I was refering to BIOS settings, not flashing a BIOS. I misread you I think. I thought you was talking about settings as there is no link to the thread you mentioned.
SO.... YES DO NOT flash a P43 board with a P45 BIOS or vista versa
Sorry for the confusion there.
