What type of 128MB RAM will the board address though? Think of RAM as a spreadsheet with X columns times Y rows. If your motherboard is able to recognize only X columns and you install RAM that is 4X columns, then your motherboard will only use the first X columns, and thus it's only using about 1/4th of the RAM stick installed. If you are lucky, a simple BIOS flash will overcome this limitation. But it is most likely hardware related. And flashing your BIOS should only be done as a very last resort, as it could cause irreversible damage to your motherboard. If you are not sure of the exact type of RAM that your motherboard will accept, check the manual, or go to the motherboard manufacturer's web site. -Dave -- On linuxfreemail dot com, I am user "spamfilter".
