DDR 2700 -333 w/ a mobo running at fsb 400MHz?

I am upgrading my mobo and im getting a board that supports P4 533 fsb and also 400 (because my current processor is a P4 478 400 fsb). it says the mobo supports DDR 266 and 333. what im confused with is can i go ahead and get PC 2700 ram even though my processor is running at 1.8Ghz 400fsb. its my usderstanding that the best memory i can get w/ my current processor is DDR 2100-266. can i go ahead and get DDR 2700 now? will it just run at DDR 2100? and then when i upgrade my processor to a newer P4 500fsb it will then run at DDR2700. i dont want to have to buy DDR 2100 now and then when i get a new processor later on down the road feel like i could get better memory but then have to go and buy it.
basically i know the mobo supports both DDR 333 and 266, but can i use DDR 333 when my processor is only a 1.8 running at 400 fsb. will it work at all and will it be stable or am i gonna have to suck it up and get DDR 266?

  1. the ram speed and the cpu speed in your case are unrelated, pc2700 will run at pc2700 (333) go for it.

    The first LAN party I went to was at a PETA convention. They booted me when I shot a crab in HL!
  2. even though i only have a processor w/ a clock of 400Mhz?
  3. yes. lol

  4. Most boards will autodetect the memory settings and set it at the proper ratio for you.
