I am about to buy a e6400 next week with the Asus 650i mobo.
I am however unsure of which ram to buy. I am looking at doing a fair bit of overclocking and don't want the ram to be a bottle neck in this.

I have been reading up a bit about ram in the past few days but am still a bit unsure of what to go with.

4-4-4-12 ddr800 run it 2.1v - push the voltage higher then push the speed, i.e. 2.2 volts 900mhz
scan these post how to check 4 errors and oc it - as long as the ram is cool/ warm to the touch under heavy load u can push it harder. if its hot, so hot u can hold on to it then u pushed to hard!

i got the corsair xms2 dominator with my e6400 and i run my cpu at 3.6 ghz rock stable.

Budget pc6400 that can run 1.8v, and has a lifetime warranty, anything above that is money better spent elsewhere. The difference between cas3 -> cas4 -> cas5 is about 1 fps each step in games... you'll never notice :)

I'm getting the same mobo and processor. But I went with the 667mhz ram instead. No real quest for overclocking. I'll have it monday.

I think both the 680i (your new mobo), and to a larger extent, the RD600 both run their memory asynchronously to the FSB. Which basically means your "slower" memory won't interfere with your OC nearly as much as an Intel chipset - so you can still OC if you want to later on.

Guys Hi

I just overclocked my e6600 to 3.06ghz and have 6400c4 800mhz corsair ram ddr2. I changed the ratio FSB:Ram 1:1 and now my latency has gone from 4-4-4-12 to 5-5-5-17 is this ok? Do i need to change the timings back to how they were now that i have made the ratio 1:1? Will it affect my performance?

Thanks :D

You are definately right that RAM is the most likely source of bottlenecking when it comes to overclocking. I bought 667mhz RAM, and its keeping my overclock back, so I would reccomend getting 800 or 1000 mhz stuff. Although, my 667 RAM can run at over 980mhz with slack timings, unstably, so I guess it just depends how much overclocking you want to do, and if you're willing to risk smoking some cheap RAM.

Hey it's simple - you can OC from 266 FSB coreclock to 333, with that memory (a 25% OC).
If you wish to OC past 333 you should use DDR2-800 which will allow 400 FSB coreclock (a 50% OC).
300 or 333 FSB is a nice little OC - but if you want more ( :D  greedy) then yes you shoulda got the faster RAM...
My memory runs 1:1 at less than its rated speed, but gives 3,4,4,10 timings with nice easy 2.0V :) 
But I guess we shoulda got each other's memory then...? LoL

Yeesh! :cry:  no such thing in Canada these days - it's all way expensive, heheh

I have the Asus 650i and an E6400... I use Crucial Ballistix DDR2800 and it works great. It's on the QVL, it's Crucial, and is some of the best you can buy. I manually set the timings when I booted the first time (4-4-4-12 T2) and set the voltage to the 2.25 option in the BIOS (the factory specs rate it at 2.2).

I made a thread at the Anandtech forums when I built it, with pictures of my build. If you want to see them just send me a PM and I'll try and find the link to the thread I made.

Oh yeah, drop the RAM in the black slots when you build your rig, it will give you a bit more breathing room from the NB heatsink.
