DDR3 1333Mhz vs 1600Mhz

Hi out of this too which is worth buy in terms of performance & speed....
I've heard dat i-5 doesn't support more than 1333Mhz RAM is it true?if yes then no use of buying 1600Mhz RAM

yep thats right -2 channels of DDR3 1333 MHz memory

See in India, you get 1333mhz cl9 latency which are cheap (and nothing special/worth for their money), 1333mhz clz and 1600 mhz cl9. So far the 1600mhz that you get are not native 1600mhz. They by default run at 1333mhz cl8, but you can clock them using 1333mhz cl6-7 or 1600 mhz default timings on stock vDRAM. If you can spend 7k approx on 1333mhz cl7 4GB, well and good.
You get triple channel and dual channel. IIRC, p55 does support 1600mhz+, but it also depends on the board that you're taking.

Ok..so if i use two setups

A: Core i-5,DDR3 1333Mhz RAM,P55 mobo
B: Core i-5,DDR3 1600Mhz RAM,P55 mobo

then there will b a speed or performance difference or not.Or is it dat the setup B will
run on FSB 1333Mhz.....even though the mobo supports it....

given that there isn't much performance difference between 1333MHz and 1600MHz, get one that is cheaper.

Yup, the peformance difference especially in gaming is nil....except DDr3 1600 consumes 30W more power..

ok then i get the 1333Mhz RAM

yup, even CL9 is okay, the performance diffeence is more noticable in AMD platform, which greatly benifits from lower CL, like CL7...INTEL seems comfy with both.
