Which Ram to Run some CFD

[Demon Siins]

Hi everyone,

I curently assembling my new computer,
My configuration so far is based on an i7 860 and a p7p55d pro.

I aiming to run Cfd software (computing fluids and dynamics) requiering a large amout of ram.

therefore i'm looking for 4x2Go kits,

the two main one which caught my attention are the two following corsair XMS:

https://www.overclockers.co.uk/showproduct.php?prodid=MY-206-CS

I'm also planing on overclocking (with moderation) my config.

So which of the 2 would you advise me to use, and do you have other choice you could advise me?

Thanks to all of you

Have you considered x58 with an i7 920 instead? Cost balances out roughly the same as the P55 and 860, but you get triple channel memory. Means 12gb is available cheaply instead of 8, and that you get obscene bandwidth between processor and said ram. Other less relevant benefits too.

CFD is going to love processing speed as well, so overclocking is a good call. I'd suggest i7 920 @ 3.6ghz with 12gb of nominally 1333mhz ram running at either 1440 or 1080mhz using a gigabyte UD5. I think you'll get better results at 1080 as the latency will be lower, but this is dependent on a fair few factors. I can say I'm at 4ghz with 12gb at 1200mhz cas6 using this setup if that's any help, but it's taken me a while to get there.

I've done very little fea work on mine (some ansys, however I don't really know what I'm doing with it yet), but a reasonable amount of modelling and consider it a noticeable improvement on my 775 quad core system.
