Not sure if this is relevant to a Breakaway forum, but, I’ll answer your question.
1) ANY 32 bit OS can only address up to 3GB of RAM, so there is no point in increasing past that point (unless your on-board video can use it).
2) DDR, DDR2, DDR3 etc are usually incompatible with each other. They may have the same physical size, but there is a "key" slot on the edge which is spaced differently, so your motherboard will only accept the chips it was designed for.
3) The motherboard chipset and BIOS will only work with a particular RAM geometry and speed. If you go higher than that speed, it will probably not run, or it will continue to run at the clock speed dictated by the chipset/BIOS.[quote author=”Milky”]1) ANY 32 bit OS can only address up to 3GB of RAM, so there is no point in increasing past that point (unless your on-board video can use it).[/quote]
Not true. The mainboard/chipset uses 36bits to address memory, and Windows even fixed the bug to be able to address it all, but they decided not to include that as a matter of licensing. Not technical inability. Leif (and many others) even "hacked" their 32bit Vista/7 installations to "turn on" this fix, and have way over 4GB.[quote author=”Milky”]3) The motherboard chipset and BIOS will only work with a particular RAM geometry and speed.

Yes most memory these days have built in reduced clock profiles in the SPD, the chip on the stick that tells the computer what its abilities are. Getting memory that’s rated faster than your mainboard is NOT a problem, but it’s a bit of a waste price wise, unless you are sure you’re going to be doing overclocking to a point that lower speed memory wouldn’t be able to handle. (not normal unless you’re using liquid cooling on your CPU)—
That being said, asking strictly what the max memory supported doesn’t seem like the best place to start asking questions about what you need. There’s Intel chipsets that support 48 GB, and AMD chipsets that support 64 GB. Most servers of any type don’t even need anywhere near that.
What are you trying to do with this box anyways?

Sounds like a question from a bot, so I’d guess it’s not trying to do anything with this box except elicit responses – mission accomplished – that’s three so far.
I agree, hence my opening line.
JesseG, I also take your point about RAM addressability, but, considering the low-tech query, didn’t think the poster would be up to hacking to turn on hidden MS fixes.
