I visited a new client today. The puter has an ASUS P2B-F mobo with a P2-350 processor. All the jumper settings are correct for the system bus speed...etc. Problem is at boot up, the bios only picks up half the ram installed. I doubled up on the ram(put in another stick of 128MB) and it is the same, now the sys sees 128MB ram rather than the 256MB installed.
OS is Winnt 4.0 sp4
Any ideas?

Double check your bios. If you can update your bios to a newer version, it may solve your problem. Go to http://www.asus.com for P2B-F bios. The latest version is 1013a.

As answer #1 stated, a BIOS update may help.

Many of the older (more than 2 years old) motherboards cannot recognize and function properly with the chip structure on the newer DIMMs.

Blame it on the continual modification of PC standards.

Ikeep an older style double sided 128MB DIMM on hand just to verify whether it is a DIMM compatability problem, or a RAM limit for the bios that is at the root of the problem.

Bottom line, you need to verify that the motherboard can recognize DIMMs larger than 64MB, and / or locate "compatable" DIMMs.
I suggest either www.crucial.com
www.pny.com
www.kingston.com
You can usually search by MB, and find their part number for compatable RAM.
