I can't recognize what specific RAM this motherboard accepts..

Dear sir,

In reply to your post- Generally now a days we use DDR400 RAM(DDR 1) for this type of motherboard.So DDR 400 RAM is More compatible then other RAM,you can use this RAM for your motherboard to obtain good performance.

good luck

Up to 2GB of system memory of PC 2700 (DDR-333)/ 2100 (DDR-266) / 1600 (DDR-200) DDR

Please see the mainboards specs in the manual:

-your board has four RAM module slots of two kind,

-of which only two can hold the maximum capacity of 2GB of RAM-Modules (2x1GB, PC2700,SD-RAM) at a time.

- any SD-RAMs labelled PC2100 and above fit your board, the newer ones (PC2700, for e.g. are down-compatible, will run with slower frequency, but fit though)

- make sure that insert two similiar (a pair)
modules, else one might go up in smoke (i learnt that, too.)

- so depending on how much you are willing to spend on new ones(that you want to use in a newer machine later on??)
u can spend either around 50 bucks (for the 2x512MB PC2700) modules
or 90 (for the 2x1GB, PC3200 version, the future option).
Up to U!
