I was going to buy one 512MB low latency pc3200 RAM stick but saw a 1GB pc4000 stick also, and was wondering if I could use it instead? The thing is, I don't know if it will be compatible, or if there are any negatives over the pc3200 version. The specs for the two sticks are below.
DDR PC4000 / 3-4-4-8 / Unbuffered / NON-ECC / DDR500 / 2.8V / 128Meg x 64
DDR PC3200 / 2-2-2-6 / UNBUFFERED / NON-ECC / DDR400 / 2.8V / 64Meg x 64
I've noticed that the larger 1GB module has worse latency. Does this matter at all when deciding which one to get (that is if I can use pc4000)?

Liars.

In a word yes. The PC4000 only really comes into its own at speeds of over 250MHz FSB, otherwise the high latencies slow it down. As Biggles pointed out 1 GB is more than enough for today's applications and having more might even slow things down as well as cost you a hell of a lot.

High speed RAM is for overclockers. If you use it, what will happen is that you have RAM capable of very high speeds but at the cost of high latencies. And you won't even be running it at that high speed, so you'll end up running slower overall.
Also, don't go for 4 GB. You'll run into addressing issues using that much RAM at high speed - most boards will want you to run it at PC2700 speeds or even less if you use so much. Every game you have will run just fine on 1 GB.
EDIT - PC4000 runs at an FSB speed of 250 MHz, compared to 200 MHz for PC3200. Default FSB speed for all Athlon 64s and P4s is 200 MHz. You're looking at a 25% overclock if you actually run at default speed for that RAM.

Hahaha 4GB.
Seriously, you do NOT need that much memory.

Sorry for my late reply. I'm looking at Crucial's Ballistix range where 1GB is only available in their pc4000 line, while 512MB is the highest the pc32000 Ballistix goes.
The reason why I want 1GB over 512MB is to fill all 4 slots on my mobo, for the sake of having the ultimate power. The system is mainly for gaming by the way, and with some people saying that 1GB isn't enough for certain demanding games (Far Cry? HL2?), I think 4GB should shut them fears up for a very long time. 4x512 would be good, but 4x1000 would be better, right?
In answer to one of the questions asked, I never want to overclock the memory (or anything else). I'm just interested in stock stuff, preferably if it's fast to begin with. If pc4000 is only for overclockers then maybe I should look for 1GB as pc3200 instead.
I suppose my final question would be... is low latency of 2-2-2-6 (512MB) better than 1GB of high latency memory for graphic intensive applications? I've been brainwashed in to thinking low latency should be my main concern, but I'm also greedy for quantity too.

Indeed - but there is no need to.
You can indeed, but why? Are you planning to overclock? It might be cheaper to buy two 512MB modules of P3200 (with lower latencies) than the one PC4000 module who's potential you might never fully utilise.
What machine is the RAM for?
