Quick OC assistance

[tinners]

Please can someone confirm my understanding.

I want to aim for a 3.0 overclock on my E6400, so this is multiplier of 8 * 375 FSB = 3000

I have some OCZ 2Gb 800 4-4-4-15 memory rated at 2.1v so will up voltage by +0.3 from stock 1.8v on board.

If I then leave my memory at 2.0 divider this means with the 375 FSB it will be running at 750Mhz ? Would it be worth me pushing up the divider to 2.1 to give a speed of 788 thus closer to my 800 rating ? Will I notice any difference ? Can I actually do this on the DS4 ?

I read I should set my timings at 5-5-5-15 initially ? Why ?

Is this a realistic target which will also mean my components wont die in a year ? Am running DS4 / E6400 / OCZ 2Gb 4-4-4-15 / Noctua NH12.

Thanks

I would asssume you slacken the timings so that its stable to start with and then you can try and bring them down.

Get it stable 1:1 first, then see what memory dividers work. For 1:1, use the 4-4-4-15 timings as this is well under the stock speed for this ram anyway.

If you find that you can easily do 375fsb and want to go higher, you can go all the way to 400fsb before you might need to loosen the timings (you may not).

Its just a case of trial and error, but definately get stable 1:1 first.

As far as I know, no boards allow such granular memory ratios.

The next step from 1:1 is normally 4:5, which at 375FSB would give a DDR memory clock of 937.5MHz, WAY over your rated speed and would require slackened timings and more volts, if its possible at all.

My OCZ gold PC6400 will reach close to 1000Mhz but the timings needed are such that I don't bother and run it at 1:1 instead.

Your much better off pushing the FSB higher at 1:1 and going for a bigger overclock on the CPU.

excellent thanks.

Thanks for that.
So 1:1 memory would be running at 375, how much of a performance difference will 2x actually make in real terms ?
