NEED MEMORY for my SL6Z3 + PROMMY, pls help!!!

[Jojo1971]

i want to get more out of my 2.4c @ 3.6 so i decided to get a prommy mach 1. im aiming for at least 3.744 GHz..

now here's my problem..should i get the XMS 4000 and run 5:4 ratio ... at 3.744 GHZ=12x 312 fsb, i will run the xms 4000 at DDR 499 BUT with loose timings of 3-4-4-8


or

get the XMS 3500 and run 3:2 ratio... at 3.744 GHZ=12x 312 fsb, i will run the xms 3500 at DDR 416 with tight timings of 2-3-3-7..


i know i can mod the vdimm for the 3500 but isnt DDR 499 too high for the 3500 at 5:4 ratio..


Experts, GURUS, pls. help me so i can pull the trigger on ordering a pair of 512mb's by Sunday night..

get xms pc3500 v1.1 which it has bh5 ic on it. dont go for the xms pc4000, it's only meant for 1:1 overclocking, u wont be able to run 312fsb 5:4 using it. 250mhz 2-2-2-5 is achievable, but it'll definitely need some vdimm. my xms pc3500 v1.1 is stable at 250mhz 2-2-2-5 using 3.3v vdimm on my p4c800 deluxe :)

Here's the trouble..with a prommie a good goal would be 4ghz if your getting 3.6 right now...So your FSB will be 333 and your going to have trouble with AGP/PCI on any board right now...even if you use clockgen to increase you AGP/PCI...

5:4 would still be 266mhz 3:2 is 221mhz. BH5 is out of the question at 5:4...trouble is 2-2-2-5 at 3:2 still beats 5:4 at CAs2.5.

the 2.6 is a better match for prommie cooling...don't know if that's an option for you though...

im hoping that works out well for you, im going to be building a very similar system shortly and ram has been something i havent quite been able to decide, i guess i may have to go with that xms 3500, i need bh5
