Pentium 3 Ram Upgrade

Mar 9, 2006 5:07AM PST

I am currently upgrading some old office PCs and was wondering if a Pentium 3 500 Mhz system can take the more current DDR ram. It currently has a 128MB PC-100 SDRAM module.
If so, will it also work in addition to the SDRAM, or will I have to remove that module in order for it to be compatible with my P3 processor?
I would outright buy new computers, but with 6 computers, that's a big chunk of change.
Thank you!

Running Windows 98SE (upgrading to XP Home soon), Pentium 3 S/N 900006-731505

You can find the right part at crucial.com

It's important to not just toss 256MB sticks into those boxes since some old machines won't accept all sticks. Crucial.com takes the guesswork out.

"will I have to remove that module in order for it to be compatible with my P3 processor?"

No.

Don't think there's a way to use DDR on PIII MBs

But as suggested....check you system/motherboard manual and armed with the mfg name, series and model number, check it out RAM options with Crucial, Corsair or Kingston. My guess is you would be limited to PC133 SDRAM.

PIII 500's

As others have stated, Crucial.com can tell you what you need.

All the PIII 500 machines I have run into could take PC100 and/or PC133 memory. Sometimes one type, sometimes the other, sometimes you could mix.

Sometimes I had to upgrade the motherboard BIOS to get it to recognize one type or a larger capacity module.
