Best (most compatible?) memory to acheive best CPU overclocking on EVGA nForce 680i?

[Papaspurs]

I'm guessing any PC6400+ EPP with 4-4-4-12 timings?

like this?... http://www.scan.co.uk/Products/Produ...uctID=4 91422

cheers

I think the link is broken. :(

But for what it's worth: i am looking for an answer to this question, too. So i shall be watching this thread closely. Although, i'm tempted to just get some G.Skill PC2-6400 HZ from overclockers.co.uk or something.

It's 7 quid more than the g.skill stuff but it's EPP which is better for overclocking (I think)

scan are generally cheaper than overclockers

Yeah, scan are quite good.

EPP really shouldn't be used for overclocking, since, as far as i know, it automatically sets optimum speeds and timings and you're far better to set them manually. Take a look at the Wikipedia article (http://en.wikipedia.org/wiki/Enhanced_Performance_Profiles). If you're going to be overclocking, don't buy RAM just because it has EPP, because you're better off not to use it. In fact, it's strongly recommended that you don't use it (well, that's what i've been told anyway).

What processor do you have/planning on getting?

[Papaspurs]

E6600

what timings are best for o/c ? 4s or 5s?

CAS4 latency timings are better, they allow for more headroom when overclocking since they can be loosened.

The low down of it is that if you're going to overclock, you're going to be turning of SLI-Ready and EPP anyway. EPP just means that the ram is holding extra information about itself, so when you plug it in to a motherboard it auto-detects the safe/standard settings automatically.

When you have OC, you have to turn these features off because you adjusting the settings yourself. In my opinion (others might tell you otherwise), the best way to go at it is with PC6400 running in Linked and Synced is probably the best way to go. I don't know what your CPU is, but if you get an E6600 or below, and you up your FSB to, or close to, 400mhz which would run your Ram at 800mhz like its specified to do, and everything would be running in Sync a 4-4-4-12 2T. You can generally get the timings down to 4-4-4-12 1t if you get your FSB to say, 375mhz which would put your RAM at 750mhz

So thats the 'why' of it, the end of it is, yeah, in (again) my opinion, PC6400 perfect.

Those who have gotten their hands dirtier than mine in this subject, feel free to point out an error.
