I'm new to the whole overclocking thing so bear with me. My new setup is:

Soyo P4I865PE Plus Dragon 2
Intel P4 2.6C GHz 800MHz FSB
2 x 256 Kingston HyperX PC3200 DDR RAM (Running DC)
Sapphire Radeon 9600XT

I got this case: http://store.yahoo.com/3btech/sipomidto02c.html

I'm still waiting on some of the parts to come in the mail, but I keep debating whether or not to overclock it, and if so, how much should I. Would OC'ing to 3GHz be too much? I leave my computer on 24/7. Could anyone give me some advice on what they would do with this setup?

I'm confused about this particular section from the overclocking guide:


PC 1600 = DDR200 = 1.6 GB/s
PC 2100 = DDR266 = 2.1 GB/s
PC 2700 = DDR 333 = 2.7 GB/s PC 3200 = DDR 400 = 3.2 GB/s
How these specifications, for example PC 1600, are obtained is discussed in more detail in an O/C forum thread.

Note, however, that to achieve these ratings the memory needs to be driven at its rated speed. If you put some PC 3200 in an Athlon stock mobo with a 266 Mhz FSB, it would just run at PC 2100. Doesn’t hurt it, but you have wasted your money because you are not running it at its rated speed. You would need to overclock the FSB to 200 Mhz to fully use the PC 3200 at its rated capacity.


If I put pc3200 in an 800MHz mobo, how much room is there to overclock? I'm not 100% sure on how the motherboard FSB caps the DDR speed.

:) the DDR is rated at its speed, so is the CPU, so just like you can OC a CPU, you can OC RAM...

a good set of pc3200 RAM can take you up to at least 230mhz i think.. otherwise to get higher, you can always use the RAM ratios to take the RAM down a notch..
I'm not 100% sure on how the motherboard FSB caps the DDR speed.
if the RAM is run at 1:1 with the CPU, then the RAM will run at the same speed as the FSB you can use dividers (5:4 3:2) to regulate this..
example:
200mhz fsb 1:1 = RAM @ 200mhz
250mhz fsb 5:4 = RAM @ 200mhz
300mhz fsb 3:2 = RAM @ 200mhz

this way you can keep the RAM at spec.. or just make it be OC'ed lower because it might not handle it...

edit: when i looked at this post i realized this may make you think that you should keep the RAM at its rated speed... no, OC the RAM as far as it can, higher RAM speed = more bandwith :)
