Hi, I'm new to this forum. I've built this computer about a year and a half ago:

MB: Asus P4PE / Processor: Intel P4 2.53 GHz / RAM: 2x512 MB PC 2700
According to Asus, this mobo can take up to 2 GB RAM. It has three mem. banks, Bank 0 could take either 1 or 2 sided, bank 1 & 2 have to be 1 sided if I want to use them both.

I recently bought a 1 GB PC 3200 (knowing it will slow down to 333 MHz) and tried it in bank 2, no POST.
Tried only one 512 MB and the new 1 GB modules, same results. I tried the new 1 GB by itself, still no POST.

About 6 months ago I'd bought the 3rd 512 MB PC2700 and put it in bank 2, the system recognizes it, but some programs crash or don't work properly.
I found out that those progs only crash if all 3 banks are beeing used (1.5 GB RAM). As soon as I take one module out those progs don't act up at all.

What am I missing?
Any help will be greatly appreciated.
