Take a look in your bios for memory timing adjustments.
It's usually a sub under advanced chipset options or similar.
If you see an SPD option, enable it.
SPD is a chip on the module that contains info about itself.
If the bios mis-reads that info on another setting, it may correct it.
If not, make manual timing adjustments using only the available choices.
Lower is faster in this case.
If it still wont see the full 1gb, something about the module itself is out of the bios's range of operation.
Could be CAS type, ecc vs. non ecc, etc. Don't have that info about the chip your using.
The board only supports DDR266/200 so even if you get the the full 1gb DDR400 recognized, you're not getting full use of it anyway. PCChips boards are well known for being flakey and unreliable too. Putting only recommended memory in it may be all it'll let you do.
Let us know.
