why ddr 3 ram has big timings? :confused:

because of high speed ? i just dont get it or because they are only first models and they not bean researched well ?

Its been answered dozens of times.

Quoted from another post:

" You cant compair the Timings on DDR to DDR2 to DDR3.

Fastest DDR was Corsairs 400mhz 2:2:2:5

I think thats about the same as DDR2 800mhz @ 4:4:4:4:10 (Mushkin) and DDR3 1600mhz @ 8:8:8:8:20, you can get likes of DDR3 1600mhz @ 7:7:7:7:18 (G-Skill)."

so if u have like for example 1333 ddr2 @ 5-5-5-15 and ddr3 1333 @ 9-9-9-26 ddr3 still will be faster ?

I would expect the DDR2 to be quicker in that case, but probably not really by that much in real terms.

The DDR2 in that scenario but you DDR2 tops out at approx 1200mhz.

Thats why I was carefull to compair DDR 400 to DDR2 800 to DDR3 1600, so it doubles up speed and Timings.
