Windows 7: RAM Troubles

So there is nothing that can be done to make the RAM work without error? BIOS settings, Windows settings, nothing?

My only answer is there is nothing that I know that can be done.
It is very well known not to mix and match ram

As has been stated, that's a bad combination you have there. I know it looks nice, but it's mixed and causing problems. With RAM being so cheap get a matched pair and lose the troubles

Since this isn't my machine, I didn't buy or install this RAM. I'll let the owner know the error of their ways. :P

So, in terms of removing RAM sticks, could someone determine which sticks need to be removed in order to achieve the maximum amount of functioning RAM left in the machine? The obvious answer would be to remove the 2gb stick, leaving 1.5gb, but is there not some combination where the 2gb stick can stay, and be functional? Perhaps remove the odd 512 stick? (two of the three 512 sticks are a pair, which came with the machine).

I've attached some screenshots from CPU-Z, if that helps.

Remove the 2GB stick, run the system long enough to determine if your issues have stopped (I suspect so), leave the 2 GB stick out if so. RAM is indeed cheap, so buying matched RAM as per system compatibility is cheaper than taking your girlfriend to the movies . Here is a 'configurator' that will help you find compatible RAM:

Buying compatible RAM also ensures the best, trouble free performance. The Acer system you mention will support up to 4 GB. However, only 64 bit will use all 4 GB. 32 bit will use about 3.25 GB.

Your problem has been well pointed out but if you'll look at screenshot 3 and 4 you'll see the problem. Besides the size they are different speeds, sometimes you can get away with doing this but the faster ram will default to the lower speed.
In your case this is not working out for you.

Fabe hit the nail on the head. The 2gig stick makes no sense in this instance.

This might sound like a silly question, but why does it matter if the RAM is running slower than it should? Surely that would be a good thing, since it isn't working as hard, and putting too much pressure on performing?

Sorry, I'm just trying to learn. :P

Well, you're right.... but then it's a waste of RAM, and issue could arise like the ones you're experiencing. That's the quick answer.

The long one can get complicated as it has to do with the way the motherboard deals with mismatched densities as well, which can impact performance of the other modules. That's why it's always better to match sets.
