Is PC3200 RAM the same as PC2-3200?

[Chris]

I have one machine with PC-3200 Ram, DDR 400 and want to use it in
another machine, but that 2nd machine requires PC2-3200 with DDR2. Are
they the same?

I have never seen PC2-3200 for sale. Is this a Dell part number?

Thanks,
Chris

They are not the same. PC3200 is aka DDR-400 and is a 184-pin DDR DIMM.
PC2-3200 is aka DDR2-400 and is a 240-pin DDR2 DIMM. Physically different
sockets.

It's rare to find it for sale these days, and was never that popular -
DDR2-533 was pretty much equally cheap by the time boards started moving in
mass to DDR2 sockets.

I'd be surprised if your system couldn't use DDR2-533 (PC2-4200) DIMMs
instead of DDR2-400, but obviously it would bear checking. Check out

DDR2-400 must be slow compared to DDR400; the CAS time for DDR2 was always
longer, only helped by faster DDR2.
