The cheapest 1GB sticks of PC3200 RAM run @ 3-4-4-8-1T timings, at stock speeds. That's
much slower than your 2-3-2-5, even though it's having to run @ 2T. They're still selling PQI Turbo in 2x1 GB sets:
link. I have those same ones, except I bought my sticks separately, and like
stevty said, they have no problems at all running in dual channel. The only time that's ever a problem is when trying to run two sticks that aren't identical, and even then sometimes it isn't, as long as both sticks have the same IC.
