Question about CPU/RAM OCing

[Dunadan]

OK...I'm putting a new rig together. The important components for this discussion are -

P4 2.4C Ghz (800 FSB)
Abit IS7 Mobo
1024 MB Crucial 3200 RAM
Zalman CNPS7000-Cu

Is there any real difference in performance in using the various DRAM Rations (i.e. 1:1, 4:3, or 5:4)?

I can test this once I build my system, but from what I've read, I have two viable options. They are as follows -

CPU OC @ 3.3 Ghz (275 FSB) + RAM OC @ DDR440 (using 5:4 ratio)
CPU OC @ 3.3 Ghz (275 FSB) + RAM OC @ DDR366 (using 3:2 ratio)

I read an article here that makes me think DDR440 is not unrealistic and that I might even be able to go higher. I am assuming that the extra memory speeds offsets any loss in performance due to the higher ration?

Can anyone quantify the hit in performance from going from 1:1 ration to 5:4?

I am not heavy into OCing and benchmarking. I am a gamer, and I like to get a little extra out of my equipment.

Thanks for the help.

This is covered in this thread.

Basically, get your CPU as high as it can go first, then use the memory ratio as close to 1:1 as you can, with as tight timings as you can. The marginal benefit, if there is any, from going to 1:1 with loose timings is very small, and not worth the price difference. I see no reason to run at 3:2 when you can get reasonably priced RAM that will do 5:4 with good timings.

That's what I was looking for. Thanks much!

I've got a 2.4c, and I settled with 3.0 because my system is rock-solid stable, and I can run my RAM at 2-2-2-5.
