Hello,
Does anyone have experience Overclocking with E8400 and DDR2 667Mhz with retail cooler..? How high should I go?

I already read that. Only consern is memory... If I to raise speeds from 9x333Mhz to 9x400Mhz... Isn't that gonna stress memory alot... 667Mhz to 800Mhz?

You can manually set the memory to 667Mhz.
Increasing memory speed doesn't gives a considerable boost to performance.

I got wrong ipression from that qquide then... I really thought that when you raise CPU speeds... Memory goes up also. ALWAYS.. Good to know. Now i can rull up my sleeves. =) Thank you.

You're welcome ;)

The guide is saying that you want to keep FSB and ram frequency at a 1:1 ratio (e.g. 400MHz:400MHz) so that they are "in sync", for a lack of a better term, because it will (arguably) increase performance.
If you have quality ram, you might want to try pushing it to 800MHz.
But if that's not possible, or if it requires too much voltage to remain stable, leaving the memory at 667MHz wouldn't hurt, per se.

RAM is Kingston Valueram 4x 2GB 667MHz DDR2 NON-ECC, total 8GB.

I would imagine you can push that RAM to 400mhz no problem. what is the voltage rating for the RAM? (usually it's like 1.8 - 1.9 or 1.9 to 2.0)

Basically, all you would have to do is set the RAM to 400 mhz to match the CPU value, and then possibly loosen the timings from 5-5-5-15 to like 6-6-6-18, if that still does not work, you can up the DRAM voltage to .10 higher that it's max value, so if the value is 1.8 - 1.9, then go no higher than 2.0, but 2.0 is still safe within bounds...
