Which is which?

Comparison here

Which is faster (in timings) and reliable?

On intel setup, 1600 vs 1866 is almost exactly the same.

The 1600 one has 9-9-9 which is faster than 9-10-9. Get the 1600.

Almost exactly the same performance. Just fancy numbers. Get 1600 mhz. The only time when it matters is if you are using an AMD APU.

if you double your speed (800MHz to1600MHz) but half your CL (CL 6 to CL 12 [half speed is a number twice as big]) your RAM is going to retrieve twice information at half the speed.
The advantage to a higher MHz is that as your MHz goes up, you also get more bandwidth, but if your CL is higher also, your ram will not be faster.

Since they are both cas 9, the 1866 will be faster, but since that speed isn't even supported... your PC might not even boot at that OC. But anyway, ideally you would get 1600 MHz ram with a tight timing. 8-8-8-24 would be great.

If you want something awesome get the Trident(or a competitor) 1600 MHz with cas 7.

i guess not, i will no lean towards the trident since theyre very expensive... Thanks guys for the responses...

Even if you do get 1866 ram, the most you'll benefit from would be like .4 to 2 fps.
