You don't say what kind of machine this is, so a lot of specific

XP SP2, ASUS A7N8X-E Deluxe motherboard, Athlon XP 2400+, currently
using 1 GB DDR PC3200 RAM (not unbranded, but can't remember make).
nForce2 boards are often flaky with PC3200 because the chipset was
created before the JEDEC PC3200 spec. However, NF2 async performance
is horrible and the XP2400+ only has a 133MHz bus, so just put the
memory bus in sync mode and it'll be fine.
Do you do that via the BIOS?
I think running "RAM" synchronously means running the memory bus at
the same speed as FSB. Yes, BIOS. It is as oppose to asynchronous
(running them at different speeds).
DDR is SDRAM, S for Synchronous. But the synchronous referred to there
is lowercase.. just means same speed. Synchronous is different to
synchronous!
I have read that one can mix speeds. Like PC3200 with PC2700. But both
will run at the lower speed. They should be the same voltage though.
The voltage that the motherboard wants. Usually 2.5v I vaguely recall.
