Is DDR PC4400 (550MHz) needed?

post #1 of 3
Thread Starter 
Hello!

This is my first attempt at overclocking. I've tried to get as much information as I could, but here I need a lil help!

My components are : Intel P4C 2.4GHz / DFI LANparty PRO875B i875P

I've seen on several articles that my CPU can reach a FSB speed up to 270-280MHz, without the need to change voltage!
As Im totally n00b with O/C, I would prefer at first not to touch at the voltages, I will have opportunities later to burn my stuff!

So here comes my question 1: what kinf of DDR RAM will suit me best?
I've watched this presentation : http://www.corsairmicro.com/memory_b...707/index.html

If I understood it well , it would be best to keep the FSB syncro with the RAM frequency! (And that's what I would like to have)
So I'll need DDR RAM such as PC4400 that runs at 550/2 -> 275MHz
Please stop me here if I'm wrong!

I know that some slower kind of RAM could reach that speed when overclocked, but then I'm not sure if I'll have to change the ratio or if I could keep it to 1:1...


Question 2:
If I compare the timing of a PC4400 (e.g. CL 2.5-4-4-8) with a PC3200 (e.g. CL 2-2-2-5), the later seems better! But I guess a PC4400 wins at the end with a faster frequency? Right?


Thanx for your help (and sorry if I said crap )

For your CPU, you will probably need to change the voltage to get it stable at 270-280 range. I wouldn't be to worried about voltages, i mean, your motherboard wont let your processor burn up...

For the memory, your correct, PC4400 is rated at 275FSB. Yes, the PC4400 memory will give better benches then the PC-3200 memory because of the higer bandwith... Besides, most* PC4400 memory will run @ PC3200 speeds with 2-2-2-5 Timings..

Uh, i would avoid the Corsair memory if you can, there overpriced and don't make very good DDR dimms..

for the memory, you want the XMS TwinX

Hmm, you would avoid Corsair but give me a link to it? I'm a bit lost here...

I think I will get this:

OCZ Platinum Edition DDR PC-4800 EL 1 GB Dual Channel Kit Elite Edition

According to this post: http://pc-tests.com/Forum/viewtopic.php?t=29882
(french site, if someone knows another one in english just tell me pls)
they have Samsung TCCD + PCB Brainpower chips

Will it be a good buy?
