P4C800 Deluxe-E

Hi all,

I have a Asus P4C800 Deluxe-E with a P4 2.6c overclocked to 3.2GHz with
temperatures of 33c idle and about 45-48c on full load. Also PC3200 Corsair
RAM.

The PC is very stable in general and also when running PCMark04 and
3DMark2001, however when I run Prime95 it comes up with a error after
running it for a couple of minutes saying something like result 0.5 but 0.4
expected. Does this mean my computer is doing wrong calculations or
something cos it runs fine in all the games I have tried.

Can anyone help me please.

Thanks.

It probably means you're getting an occasional memory error and since Prime
95 is all math, and only math, any 'blip' is an easily detectable bad
answer. A 'blip' a game, however, as long as it doesn't happen to fall in
an important code segment (the 'odds' of it causing a 'crash'), isn't going
to be fatal and probably goes unnoticed, hidden by all the display complexity.

Prime95 will also show the 'blip' quicker and more often because it's
concentrated on doing that calculation in and out of memory as fast as it
can (heavy load) and isn't regularly 'diverted' to 'other things' like a
game is.

Also note that code goes through the error correcting processor cache
whereas direct reads and writes to memory (as Prime95 might do) may not and
so show as an error when the other would be 'fixed' (albeit slowing the
processor down with a cache reload).<!-- ~MESSAGE_AFTER~ -->
