What type/speed of RAM for best OC

[bh33]

I'm just about to purchase a new system and I'm not sure what type of RAM I need to get the best OC. Now the mobo's I'm looking at getting the Gigabyte GA-P35C-DS3R or GA-P35-DQ6 with a E6850 and an Nvidia 8800.

So I really have 2 questions does the 6850 overclock better than the 6750 and what type and speed of RAM do I need to get the best overclock. I was thinking of maybe getting some corsair dominator but I really have no idea when it comes to choosing memory.

Noob

Most ddr2 800mhz will do, like this cheap corsair ram with 4-4-4-12 timings, http://www.newegg.com/Product/...x?Item=N82E16820145034

It will allow you to run 1:1 with your CPU up to a FSB of 400. With the e6850 that means 3.6ghz, with the e6750 it means 3.2ghz. If you lower the ram timings to 5-5-5-15, you can probably get 450mhz out of that ram, and do3.6ghz with a e6750 and 4ghz with a e6850 running 1:1. Running 1:1 between your ram and cpu isn't 100% necesary though, using a ram divider will do the trick as well. Personaly I wouldn't invest to much money in ddr2 1066mhz since they cost so much more, and the cheaper ram will allready allow you to overclock pretty far.

The e6850 will oc better than the e6750, especially because of the multi. I've seen alot of e6850 go past 4ghz but rarely have i seen the e6750 go past this mark (on air cooling). For memory wise i would go crucials ballistix 8500 for price/performance/micron , heard good stuff from friends that have them.

Do you think the 8500 will out perform the 6400? I think for 2GB of RAM it will cost around $200 for 8500 and $100 for 6400. Also do timing matter all that much or does it matter the slower the RAM is? For example if I get 6400 do I need lower latency and for the 8500 it doesn't really matter?

Ram timings or somewhat a non issue, the difference between 4-4-4-12 and 5-5-5-15 is negligible for example. And the 8500 won't outperform the 6400, it will only allow you overclock further without having to overclock the ram or use a ram divider. So for example, if you want to overclock past 3.6ghz with a e6850, the 8500 will allow you to do so with less hassle then the 6400. This is even more true with the e6750. If your goal is 3.6ghz though, then ddr 800 is fine.
