F3-17000cl9q-16gbzh @1600

[Cartel]

I'd like to buy the F3-17000CL9Q-16GBZH and run it at 1600 speeds and lower the timings.
Whats the best for this?
I want better performance than my F3-10666CL7D-8GBXH.

What should I do?

The issue is my F3-10666CL7D-8GBXH ram is slower than my old DDR2 PC8500 that was 5-5-5-15.

I would like to get F3-17000CL9Q-16GBZH and set it to 5-5-5-15 at 1600

Advice?

Think you should run a memory performance test between the two (1066 and 1333) to see see the difference, maybe something like Maxxmem2 Preview or SiSandra, think you'll see the 1600 is much faster and has far higher bandwidth. I think you may be equating the base timings as a speed factor, which to a degree is true, but overall (if the sticks are running correctly you'll find that, as an example

1066/CL5 is a bit slower than 1333/CL6 which is a bit slower than 1600/CL7 which is a bit slower than 1866/CL8 etc.....generally with basic sticks as the freq goes up the CL needs to go up also, same can happen with the individual stick size i.e. you can get a tighter CL with a 1 or 2 GB stick than a 4-8 or 16 GB stick. The lowest CL (base) I've seen recently is CL6 on 1600 sticks which is in GSkills 2x2GB set F3-12800CL6D-4GBXH.

Even with that as the freq goes up, you'll still see better performance, bandwidth wise.

With the F3-17000CL9Q-16GBZH set, I'd guestimate you could prob run them at 1600 with around 7-8-8-25 or so, though by dropping to 1600 you'll lose bandwidth (and this would be on an Intel platform)

Another thing to consider is even with the 1090T, with 4 sticks you may have problems trying to run 1600 at a real tight CL. The AMD MCs Memory Controllers don't generally like tight CLs at higher freqs.
