samsung ddr333.how good is it?

i was out to get ddr400 but couldnt find any,so ended up with 333.whats it like for overclocking?

The Samsung PC2700 is very good for overclocking. Number one, make sure you are getting the CTL version, not DTL. Also the ram requires some burning in to reach the highest speeds. I am using Corsair XMS 3000 DDR which got me to 200 mhz fsb with the vdimm at 2.8v.

whats the difference?
