Official ASUS X38 Boards: P5E, P5E3 - Info/BIOS Thread

[TKC]

Like I mentioned before, this could be related to the kind of memory used.

Do you know if is possible to flash back to older bioses? I have the 0107 installed, but I don't want to try more recent ones if I cannot flash back

Yes, memory is the key point, I can use all divider on 0107, while 4:5 and 5:6 are mission impossible on 0501, but this is the experience base on my rig, just for your reference.

If you are running 32-bit XP/Vista, you should be able to flash back to old bios by AsusUpdate 6.10.02 in windows envirement, otherwise you have to purposely corrupt your bios and let CrashFree flashback to 0107, but be careful as the CrashFree program itself also store in CMOS chip and will be reflashed as well in the bios rewriting process, so you bear the risk of returning your board for repair if CrashFree fail to work.
