756 or 512 of the good stuff

I have 3 sticks of 256 ddr 2100 memory, I was thinking about buying 1 stick of 3700ddr memory "cas 2" I do alot of video editing on my windows xp computer. Is one stick of 512 memory enough for windows xp ?

Thx for help

go with the 768, put it in 4 way interleaveing. unless your runnin a 200mhz fsb the system cant take advantage of the added speed of 3200.

For video editing I would also use 768 MB.

Win XP reserve ca 128 MB of resources.

If you want more performance than get the 768 MB that your SYS must not write so many Swaps on the HDD.
