What is the performance difference between DDr2 1066 @ CAS5, and DDR3 1066 @ CAS5?

Is theer any?

I could be wrong, but I think the ddr2 will bench a little higher, only because you have to run a 266fsb to get there.

but where you could push ddr2 to 1066, you could push ddr3 to 2133, and thats no contest

But he is an Phenom user max Ram he can use will be 1866MHz (WITH OVERCLOKING) and it won't give him a noticeable performance.. ^^ DDR2 1066 with C5 will dominate DDR3 with c6-7 .. Easily

I wasnt asking reguarding my CPU, i was just wondering in general. I like the 266 FSB answer, but i need 266 to get my DDR3 @ 1066 also.

I don't know where you get a lot of your info from, but for a fact phenom just like intel dont' have a max really it all depends on your motherboard supports it. mines supports up to 2000Mhz. And this clearly shows that DDR3 dominating DDR2 easily, not the other way around.

EDIT.
And you can get any ram thats DDR3 because you can just down-clock the ram thus giving you better timings smile.gif. just make sure your board is compatible with DDR3 ram first.

Those aren't the same speeds.

Theoretical bandwidth is also but one aspect of overall performance.

Exactly.

Currently i have my RAM downclocked to 1066 CL5, does anyone have DDR2 1066 CL5? I would like to bench them.

Thanks, right now my FSB is 267 for DDR3 1068 @ Cl5.

Here are the DDR3 results. My RAM is a little higher than it should be but thats just FSB fluctuation:

EDIT - Im going to go back to my previous 1333 Cl6 and see how that compares.
Heres the DDR3 CL6, its not that much lower latency, so later when i get the chance i will get as high a clock rate as i can and drop my latency to 5.........or ill just put DRAM voltage to 2.0 and not fiddle with anything else biggrin.gif. One of the benefits of having micron D9's paired with AMD IMC.
