I've been thinking about upgrading my RAM. Currently it's at 2GB, and i'm thinking about bumping up to 4GB. It actually says that it has 2.5GB but only 2 is available. What is that about? My motherboard is an ASUS M3N78-EM. I have two empty slots for RAM. Supposedly it can handle up to 8GB of DDR2 1066. What's the difference between 1066 and 800? Why does my load screen say that it's 2.0 ghz when it's supposed to be 3.2 ghz?

IF you have a 32 bit operating system, adding more RAM won't do you any good, since OS will not be able to utilize it.

Do you notice any performance issues that makes you suspect that you need more memory?
Or are you just doing it to have 4GB?

Unless you plan to upgrade to a 64bit OS, the upgrade to 4GB won't make any difference performance wise...

I'm running windows 7 64. I don't need to upgrade but I figure why not

Well, if you want to throw money at it, then fine, but a dedicated HTPC doesn't really need any more than 2GB, whether 32 or 64bit.

Memory is cheap though, and on a recent rebuild of my HTPC, I decided to put in 4GB this time. Don't see any real benefit, but at least I know it's there.

Actually, I believe 32 bit uses up to 3.5 GB or thereabouts.

4GB is probably unnecessary, but on Newegg right now the cheapest 2x2 is only 1 dollar more than the cheapest 2x1. So you might as well get it.

Since you are upgrading, if the 18 dollars is significant to you, then monitor your usage and consider whether you do anything that would make the upgrade worth it.

Your motherboard's integrated GeForce 8300 uses up to 512MB. It's adjustable in the BIOS.
DDR2 1066 is supported by some AM2+ CPUs. Is your existing RAM 1066?
What CPU do you have? Should it be at 3.2Ghz? Check your BIOS settings to see if it is set to run underclocked.

Right, a Vista 32-bit computer I bought in 2007 had 3 GB of RAM installed because that was near the usable limit.

Just about every day there is a 4GB kit of RAM for less than $20. Today, for example, there is a well respected brand of DDR3 1600 for $18 shipped.

Thanks. I'm asking questions because I really just don't know. I'm new to the whole computer thing. If I go into the BIOS and just look around it isn't going to mess anything up, right? Can someone explain 2x1 vs 2x2.

It's an AMD Athlon 64 X2. I'm not positive on my existing RAM.

Get 2x2.

With that said there is only about a 5% performance boost over a single stick. Its a myth that you HAVE to have a 2x2 kit. But for the same price or less get the 2x2.

What's the difference between 533, 667, 800 and 1066? I get the difference between 1GB and 2GB...

Speed.

Get the max your motherboard can handle.
