When can P3 take advantage of DDR?

I think I remember reading somewhere that a P3 can begin to see benefits of DDR when running at or above 166FSB. Is this correct?

I have an 866 that will do 170 (or more) but it's not in my P3 DDR board. If I can get a performance boost, I may do some hardware swapping.
 
Even at that bus speed I doubt the difference would be anything to warrant any kind of expenditures.

As far as PIIIs go, I've not seen anywhere that anymore than a 5% increase in memory bandwidth has occurred over using SDRAM. Intel just doesn't seem to take advantage of DDR the way AMD does in my opinion.
 
Right, you'll only see a 5-8% increse with the DDR and a PIII rig.....so unless you are planning in getting a new mobo to use the new Tualatin core don't buy a PIII + DDR mobo.....or one like the one I have a dual PIII (Tualatin) + DDR.

I changed my WU crunching from 7.25 to 7.1 h per WU when I changed from my old mobo (an Iwill BD100+ with 440BX chipset) to the DVD266u-RN (Via Apollo 266T). I think this setup rocks but I well beyond the 4 h per WU limit.....

Go here if you want to see more of the DDR+PIII combo chipset.
