ram and cooler for overclock e6600

[ashagplz]

looking to do a stable overlock on a e6600 and a Gigabyte GA_965P_DS3P..

im confused as to what ram you guys are suing though....are you using pc6400 and sticking it up to 1333 fsb and over? It seems almost double its rated 800mhz.....or am i reading it wrong..does it run dual channel and so reach 1600?

anyway explanations for someone coming from nforce 4 platform and recos for ram and cooler for above system...

You are confusing the DDR2 rating with the actual speed imo. You would be extremely lucky to get any 6400 ram to reach 1600mhz. a lot of the micron D9 modules (cellshock/teamX/Ballistix) will go in excess of 1000mhz(500mhz actual) and some go even further upto 1400mhz+ if you are really lucky. I havn't seen any units that can achieve 1600mhz(800mhz actual) though.

I would go for a set of 6400(800mhz-400mhz actual) ballistix. You can get the 5300 ones which are allegedly the same chips and will clock just as high but I have a sneeky suspicion they are speed binned and you raise your chances of a better overclock with the higher binned memory. At the prices now you can't really go wrong.

Ignore the 1333mhz FSB claims by Intel. They quad-pump their FSB's, so they're 'really' running at 333mhz. Tho their current Core 2 Duos are running on a 1066mhz FSB (266mhz).

So go by the 266mhz rating, which means you need 533mhz RAM (pc4200) to run at stock.

Most people buy pc6400 or good clocking pc5300 when overclocking.

so on a stock system what ratio/divider are boards running given that the cpu is running 4x266.....systems have 800mhz memory (400 actual).... clearly they arent running 1:1

The divider would be on 2:3 to have the memory running at 800mhz on a 266mhz FSB.
