Is there a significant different between DDR 400 and DDR333

I'm using a slot 754 DFI Infinity Nf4x, which also many memory speed limitations. There are 3 memory slots, and using just TWO of them with Double sided sticks will make it run at DDR333. I have two 512mb Corsair Value DDR 400 sticks, but they run at DDR333. Is this a significant difference that I would notice lag in games like Battlefield 2142?

Is single sided ram normally used anymore?
Thanks for the help.

  1. If you are stuck at 333MHz try tightening the timings a bit further, you should get a little bit more performance.. :D
  2. I can't say I've ever seen a single sided stick of RAM in my life.

    Well, unless you count on my P166, but that's... I don't want to count how old it is. It should rest in respectful peace.
  3. Thanks for the replies, I might buy another 512 or 1gb in the future for Battlefield too.
  4. If this is for BF2, 1gb-1.5gb is all the ram you'll need. I would say 1.5gb is fine for BF2142 as well, but definately wouldn't need more than 2gb :D:D
