Hello all :) 

Ok, I have heard that 1600mhz is not a very big speed increase from 1333mhz. Is this true? If so, how small of a speed increase is it?

Thanks in advance! :D 

Best solution

Ok, tyvm! Just checked it out and it answered my question :) 

So yea, not worth the money then :)  Would do better to look for 1333mhz with low numbers than 1600mhz.

I've got the dominator 6GB DDR3 1600 kit from corsair on an overclocked i7 920, and the 1600 really is for bragging rights only. The only thing I'd be concerned about is getting crappy ram and then having it restrict your cpu overclock, but with the many bclk multiplier ratios thats probably not even a problem.

Yes and also 1333MHZ RAMs have mostly lower timings compared to 1600 models

ddr3 1600 cas7 is faster than ddr3 1333 cas6

and its cheaper, there is no reason not to buy it.

Its faster but not much,the advantage of DDR3 1333 CAS6 is its lower timings which are better for OC'ng,they both are good :)  one has faster frequency and the other one has lower timings :)

Actually, DDR3-1600 C7 has lower timings than DDR3-1333 C6. 1600C7 has a latency of 8.75 ns, while 1333 C6 has a latency of 9 ns. It's only a minor difference, but the 1600 C7 comes out ahead.

I did a search and found that there are some 1333MHZ models that have lower timings than 1600 and as u said its vice versa too.
DDR3 1600 with 7-7-7-24 timing:

DDR3 1333 with 6-6-6-24 timings

I thought its like DDR2 800 and 1066 which in almost every RAM i saw,DDR2 800 had lower timings,but after a search i found that its not the same for DDR3 models :D  but as u said the difference isn't much either :)
