Could you please post the 7-character model number of your R50e so we could guide you in the correct direction?

I don't think it matters in this case, George. All R50e models were exactly the same when it comes to design and chipset.

The R50e has two RAM slots. One at the bottom of the machine (accessible by removing one screw) and one underneath the keyboard (accessible by removing the keyboard - 3 screws).

It takes DDR-333 (PC2700) RAM. DDR400 (PC3200) will also work, but downclock to DDR333 speeds.

DDR modules only came up to 1GB per stick, so the maximum for this machine would be 2GB. My neighbor recently did such a 256MB->2GB upgrade and (suprise, suprise), discovered night and day difference in performance.

If your machine has 256MB, it means it has one stick (I don't think R50e's ever came with 128MB sticks). This stick would be in the primary slot (underneath the keyboard) and the other slot (bottom of machine) should be free. This means you can upgrade to 1.25GB just by adding a single 1GB stick and without having to disassemble the computer (if you feel uncomfortable with that).

I believe (maybe I'm wrong) that some R50e units sported Celeron CPUs and 533Mhz FSB...

Please remove your serial number from the post, it should never be exposed in an open forum...

Try this guy on eBay, that's a nice price and I've bought RAM from them before:

Good luck.
