Overclocking Corsair XMS 3200 C2PT

[DCypher]

I have begun tweaking my RAM settings. They were originally 2.5,3,3,7 and now are 2.5,2,2,7. I still don't understand overclocking RAM. Is my goal to get lower latencies that I have now? I read through some articles but am still unsure. I have also read that the last number should be the addition of the cas, the tras, and add 2 to that. Is that right. Also are the 2 middle numbers supposed to be the same.

Also, is overclocking RAM the same thing as overclocking the CPU?
I am also confused with the ratio.
I have a p4 2.4ghz with a 133fsb and 533 bus speed (by the way, what is the difference between those numbers). Someone told me I cannot run 1 to 1, why
Is it the RAM frequency that can't be higher than the front side bus, or vice verse?
my current setting are a fsb of 145.6mhz (o'ced a little) and my RAM is 182 mhz.
what happens when i get the ram to 200mhz, can i go over that?

I know these are a lot of questions but i really would appreciate answers to them all, even if it takes a couple posts. Thanks everybody.

btw is it okay for me to run my RAM at 2.9V always

basically when you change the timing on your ram you are not changing the speed of the clock but the number of clock cycles the ram takes to do its thing.
lower timings will give you better bandwidth as the memory is doing more work per clock cycle,but at the cost of instability.
that ram will do 2-2-2-5 at 200 MHz easy and that dim voltage is fine as you oc the system you will need more voltage to open and close the rams transistors in a cleaner way. corsair ram loves voltage.
i may be a total Intel idiot but in amd systems the xp ones at least the system speed is determined by fsb * cpu multiplier, so the fact that you have a clock for each is interesting.
I do know that Intel uses a quad pumped bus or some such so to run your ram in sync would require 250 MHz i think or more maybe 500. thats why you cant set the ram 1-1 "unless you have pc5000"
like i said I'm an Intel noob so I may be off base but theres some thoughts for you D

From my expierence all the new XMS 3200C2 overclocks about as good as the Corsair Value stuff. Back in the old days before LL series hit the streets, you could get BH5 ram in the C2's and overclock the crap out of it.

GL on your overclock.

In theory, If I tighten my timings it will be harder to overclock my cpu?

The further past ddr 400 that you push the ram, the more relaxed the timings must be (higher numbers). Or if you push your cpu past 400 fsb and still want to run tight timings, you can run the memory on a divider to bring it back down to ddr 400, but generally it works better to run it 1:1 with relaxed timings. You just gotta experiment to find what works best for you.

And how does 3200XL overclock, i.e. is it worth the extra bucks?

I plan to use it on DFI lp ut nf3 board with newcastle 3000+.
