Ok i just went searching on google and found the code
PTGD1-LA

popping up a lot next to the words "Puffer 2", so i'm assuming thats the code for it... but looking at the following page:

http://h10025.www1.hp.com/ewfrf/wc/d...product=426755

Tells me that the FSB is only 800Mhz, so does that mean i can get a core 2 duo/ core 2 quad so long as its FSB speed is the same as that?

Also it says memory wise only a speed of pc3200 tops... but do you think this could be back then there was nothing faster? It does say 4gb of memory is approved which is nice!

If you have: DDR2-SDRAM PC2-4300 (266 MHz) - [DDR2-533], you can't be using that board. It only has DDR slots, not DDR2. Sorry, that's not your MB. I found this one with the Puffer 2 when googled some more. http://h10025.www1.hp.com/ewfrf/wc/d...name=c00361570 Seem familiar?

It's freaking unbelievable how bad the HP site is. http://h10025.www1.hp.com/ewfrf/wc/p...&product=61026 It just totally sucks. You can find all kinds of useless crap there, but nothing of use.

What you are suggesting is impossible. because you want to use ddr2 6400 is fine but it will read 4300 anyway, you can usually only jump 1 speed either way. And the board is for a P4 so it cannot handle any of the Core2 duo series and certainly not the Pennryn either or any Quad cores.
To do any of that you need to buy new as the most of what you would do would be barely noticeable. reinstalling a fresh XP would probably do more for speed and upping the ram 1 more gb would be about the most that would do anything.

Ok i half suspected that... i'll just buy a new base unit off ebay... for the same price as all them upgrades i could as easily get a brand new pc that would probably be as equally powered!

RAM speed (I think often called bandwidth) is in Megahertz (MHz), but latency (aka timing), is very different. There are all sorts of latency numbers, but the four you most commonly see are the most important. In RAM latency, the smaller the numbers, the faster the RAM is going to function. You can pretty much never have the highest MHz with the lowest timings, due to the hardware limitations, but having low timings with a little higher bandwidth is better for some things, while having high speed (MHz) with a little lower timings is better for other things.

Currently, from what I've read and determined, DDR2 memory with the lowest timings (like Corsair's 3-4-3-9 DDR2 800 MHz) is faster in some (key word: some) applications than most DDR3 memory with high bandwidth but much higher latencies, like 1600 MHz with 9-9-9-24, etc. But after a while, DDR3 memory will probably catch up to near the timings of DDR2, or at least near enough to beat it in gaming and most applications.

Low latency seems to be better for 3D gaming, while higher bandwidth is better for things like video editing and similar things.
