Hey Jaymes,
I was just googling around for overclocking on the AMD Athlon 64 X2 4400+ when I came across your post. I'm figuring on building a 'puter around this cpu in the coming weeks. I have almost no right to do even THAT much, coming from being a power Mac user all my life. But hey, if you're gonna go, go big. And learning more about the puter I'll be sitting in front of for 60 hoursa week probably isn't a bad idea for a slamming pc intro.
I found a heap of articles that might be of inerest. First, about RAM, specifically about latency and what it means (basically how many clock cycles for an instruction to process through EACH step before it completes (lower is better). Premium (errr, SUPER premium) RAM (that is 50-60% more than basic RAM has the lowest latencies possible. That is like RAISING clock speed on your bus, kinda. It also allows overclocking your bus, so the latencies can raise a bit and still run at very, very normal settings (like your basic/budget ram USUALLY runs).

I'm not really sure what this article is about, it seems to stray off topic after page one, but this guy Tom really knows his %$@3 on everything that has a keyboard or processor:

Okay, now check out the king of low latency RAM, and their latency settings here (notice the TWIN1024-3200 XL is absolutely the lowest possible settings at 2-2-2-5):

If you thought you knew it all, read this for a great summation:

Okay, now that you're ready to overclock your system, just by the sheer fact you've read about SMALL performance gains, check this out:

Tell, me why does anybody buy a Pentium D 840 with benchmarks like THAT?! It gets ripped apart by the Athlon 64 X2 3800 in virtually every test. And the 4800 ridiculously faster. Hooray for AMD.
Now imagine that I'm buying the 4400 'cuz of value (same FSB, 2MB cache, yada yada) at $300 less than the 4800, right? Now what if I got me some Corsair XMS 2 x 1GB DIMMs for that $300 running a 2-3-3-6 latency. Then I went and overclocked my bus from 2.2GHz (11x 200 MHz) to say a very safe 2.6GHz (13 x 200MHz) and had the RAM running somewhere around 3-5-5-8.
Wow.
but don't try that with basic Crucial or Kingston RAM, it might overheat or just freeze up, right? "Cuz at a starting point of about 3-5-5-8 it couldn't really handle the overclock at all.
Does that all make sense?
BTW, here's my system plan posted in a CNET forum:
http://reviews.cnet.com/5208-6142-0.htm...D=26&threadID=128545&messageID=1452468
But I've actually revised a few components in the last few hours.
If you're okay with spending the extra $100, spring for 2 x 1 GB. This is great performance ram, just a step above the basic stuff (has aluminum heat spreaders), and is the SAME price or less than basic Crucial/Kingston RAM modules ($220 total):

2 x 512 mb Corsair or Geil will run about $100.
My strongest advice is to buy RAM in pairs. I'm sure you prob know this, with a dual processor; but since you've asked what kind to buy, that's MOST important.
Cheers, let us know how your build goes.
