Difference between "low density" and "high density"?

What is the difference between "low density" and "high density" with memory, and how do I know if my motherboard will accept high density memory?

This is my current motherboard:

Gigabyte Technology GA-K8N-SLi

I know that I need DDR400 memory, but can I get both low and high density?

I've found that high density ram mostly deals with server boards, most of it is also ECC (error correcting code)
Most non-server boards aren't compatible with high density ram and only read it as half of what the ram actually is (1gb as 512mb for example) that is if they even read it at all.
It's safe to assume that your board isn't comatible with the high-density ram.

Check this out for Low vs. High info:

Since this is an older mobo, I'd go with best quality low density dram affordable. OCZ & Corsair come to mind.

There are certain batches of high density memory modules, that some vendors claim to work with the chipset (NVIDIA nForce4 SLI MCPs) on this board. However, you need to get a confirmation from Gigabyte Support, exactly what brand or size of high density dram that might be. Even if a vendor tells you that the high density mem they have will work on your board, confirm that with Gigabyte. (Don't purchase high density no-name modules from any vendor.)

The supposed advantage of high density mem over low density mem for OCing is an unproven theory in general.
