That pretty much relies on the fact that you ram may be unstable. As long as it's all stable then you should be getting the same overclock. I'd start with one 1GB stick.
I read somewhere that I'd have better luck OCing my Athlon64 with only 1 GB RAM

...so I took out my two 1 GB sticks of supertalent DDR400 @ 3-3-3-8 and replaced them with two 512 MB sticks of Crucial Ballistix DDR400 @ 2-2-2-8. I originally thought I would improve the PC's performance by swapping the two 512s for the two 1024s, but now I'm not so sure. I appreciate any input.

..........there now I took out the unnecessary information, I hope it's easier to read

ny_driver, K8s being what they are, they generally tend to OC higher if the load on the chip's IMC is lighter (i.e., the less RAM, the lighter the load on the integrated memory controller, and therefore the lighter the load the CPU has to take on as it is forced to run faster than stock speeds). As a rough generalization, you can get more CPU speed if the system is lighter on RAM.
However, this is just one part of the equation. While there is some truth to the saying that "CPU speed is king" with K8s, overall system performance depends on more than just speeding up the CPU. A good rule of thumb in almost all cases is that your system will perform better with more RAM than with less. All other factors being equal, a system with more RAM will always outperform one with less RAM.
Unless you're able to really pick up a dramatically significant boost in CPU speed (as well as being able to sustain a high-enough RAM bandwidth through memory OCing -- remember that the RAM's clock is tied to the system's reference clock), I'd say that you're better served by running 2GB as opposed to 1GB. This is especially true if your gains in CPU speed are modest (less than, I'd say, 500MHz from stock).
