What do you guys think is better:

255 fsb (cant go higher with 5:4 stable) with 5:4 dram ratio and 2-3-2-6 timings

or

287 fsb ( and i can probably get a little higher stable) with 3:2 dram ratio and 2-3-2-6 timings

Specs are in my sig,

Thanks

Just wanted to see what other people thought about it :) I'm still having a hard time with 5:4 ratio going over 255 fsb...

definely 255fsb. that is mostly counts in performance. plus the timing are still very good. and eventually the timings are going to get to a point where you dont even notice a difference.

You could just run 3dmark2001 with both settings, and see for yourself. or you can trust a bunch of anonymous people on the Internet.

3dmark? um k, cobray im looking for opinions yes i know i can run benchmarks but im not a pro either, pimpshin like i said in the first post, timings are the same for both speeds.... Right now I'm at 255 fsb with 5:4 divider, no memtest errors, and prime stable.

292 fsb/1.5= 194 255fsb/1.25=204.

Comparison of the memory speeds; Now at 292 fsb im running at 3.5ghz where at 255 fsb im running at 3.06ghz. Difference between memory buses are 10, but the higher fsb (292) will compensate for the loss of bandwidth using the 3:2 divider and would result of greater performance. Anything else than 290 fsb i would just go for the 5:4 divider....

What do you guys think?

5:4 is better than 3:2 anytime.
Only when it gives better performance:)

I have seen people post great results with KHX3200
but with a voltage limitation of 2.8 you'll not get to 292 5:4. If you could get to 275 or 280 there might be some guessing involved. You'll have to do some benchies and check it out for yourself but I have no doubt 292 3:2 will outperform 255 5:4 at most any benchmark or test you can conjure up.
Sounds like you know what youre doing,but...
Can you not run 2-2-2 3:2 though? Are you using max vdimm? You should be able to squeeze more out of those sticks...
Good Luck!

I'll see if i can run at 2-2-2-6, yes i am using max vdimm (2.8).
