Memory compatibility with ASUS Mobo

[foxdelta]

Hi there,

Can anyone give me advice on DDR memory compatibility with my ASUS P4P800S-X motherboard please?

I currently have 1 GB of PC2100 266mhz memory in my system but I want to upgrade. I can only afford a stick of 1GB Kingston DDR400 PC3200 serial number KVR400X64C3A/1G which (I hope) will work on its own in this mobo. I want to know if I could mix the 2 sorts of memory (DDR400 & 266Mhz) to give me 1.5 GB of memory. Next month i will buy another 1GB stick and replace the 512MB PC2100 so this is only a short -term problem.

Thanks for the advice.

check the compatible list on ASUS site.

Finally got 2 sticks of the Kingston 1GB PC3200 DDR400 running in my machine and what a difference 2GB makes! Of interest, the mixed RAM did work only that the speed was recorded for both at 266mhz.

Thanks again.

Any machine will always clock the faster RAM down to match the speed of the slowest DIMM.

ASUS boards are extremely picky on ram. Stick to the manufacturer's recommendations in the mobo book.
