I have customer that needs to have 4GB of RAM on their computer. He
has three 1GB Sticks from one manufacturer (unknown) and another
generic one we sold him. The number of chips and the Samsung part
number on the chips are identical. On boot up the system only sees
3.5 GB, and at least once while running the computer, the computer
made a poping sound and the app he was working in crashed, but windows
was still running. The motherboard is a DFI PS-83.

Anyone know what might be going on with this?

That's almost deifnitely a BIOS issue.

Could be, or a chipset issue, but it all depends on what "the system only sees
3.5GB" means, exactly.

eg: no desktop version of Windows supports more than 3.5GB of memory...

When the computer POSTS, it only says the computer has 3.5GB Inside
of windows it also says 3.5 Windows does support up to 4GB, but a
single application can only use 2 of it.

The BIOS is probably remapping 0.5 GB of high memory to PCI cards, AGP
graphics cards, &c.

Hi,
The reason is this ....
System reports 3.5GB rather than 4GB.
This limitation is caused by PC architecture and the missing 0.5Ghz memory
address is reserved for PCI I/O space, AGP aperture mapping space and other
onboard device I/O space.

I found this info on Abit`s website Faq and i asume it will apply to your
Motherboard as well.
Hope it helps.
