I recently added some ram to my pc, took out the 256 meg DDR and added a 1 gig stick of DDR. Running much faster, but I'm curious, would I be able to put that old ram back in, in addition to my new ram to make it that much faster?

This isn't really a yes/no question. Is it possible for you to see the make and model of your motherboard, how many slots you have total, and how many slots you have filled, and what they're filled with?

I think in most cases you have to fill the RAM slots evenly.
So you would need another gig stick, more than likely. RAM is pretty cheap these days, though, if you want to go for that.

Probably, but I wouldn't know what it is. The pc is a compaq presario, 2.4 ghz processor. It has three slots I believe, one of which currently has the 1 gig in it, the other two are empty.

It would be better to confirm this with an exact model number (it should be 3-4 digits and stamped on in a way you can't remove), but most motherboards with three RAM slots don't support dual channel, so you can just pop the old stick back in and benefit from it.

If I recall, crucial.com has a nice memory adviser tool.
As far as different types of memory in different slots, it depends. Generally it'll work but how optimal is the question.. I have a Core i7 processor now, and it's preferred for it to fill three slots with the same amount of RAM (or multiples of three). A much older computer of mine with an Athlon XP liked dual-channel, so the best was to have two sticks of the same RAM inside.

Q: What memory goes into my computer, and can I mix speeds?
A: DDR memory with support for DDR PC2700,DDR PC3200 speeds.
Because DDR memory is backward-compatible, you can safely upgrade your system with any of the guaranteed-compatible DDR speeds listed below, even if your manual calls for PC1600 or PC2100 speeds.
Q: How much memory can my computer handle?
A: 1024MB.
Adding the maximum amount of memory will improve performance and help extend the useful life of your system as you run increasingly demanding software applications in the future.
Q: Do I have to install matching pairs?
A: No.
No, you can install modules one at a time, and you can mix different densities of modules in your computer. But if your computer supports dual-channel memory configurations, you should install in identical pairs (preferably in kits) for optimal performance.

Now, having read all that.. according to the adviser, I should only have 512 max in a slot, 1024 total. I have 1024 in one slot, nothing in another. Will having too much ram in that one slot burn anything up, or is it bad for the PC?

No on both counts. Your computer just isn't capable of using it right.

If I remember right (and this is a stretch for my memory, so take it with a grain of salt--I can't find the answer through Google), the problem is that your motherboard can't bus the whole thing, so what you end up with is 512k of standard usable memory and 512k of unusually fast virtual memory.

I'm using an Intel D945 motherboard with 1.7 GB of RAM in it. Three 512 and one 256. Works fine, just can't run it in dual paging mode (which basically is like dual core CPU, except for your ram).

Still couldn't run Crysis, though.

WHOA... thanks! I know it is costly to upgrade memory on a laptop. The Mac Genius Bar people suggested that purchasing an external hard drive AND upgrading RAM was the best way to get a nice long life out of this MacBook. Though, I never realized how cheap RAM was!
Looks like I am currently running two 512 MB DDR2 SDRAM and can upgrade to two DDR2 PC2-5300 with a maximum of 1GB per slot. All this will only cost me about $30. Seems worthwhile... though I don't quite understand the difference it will really make. But for $30? I would gladly spend that money!
