Well, my PC Ram is only 494mb. It couldn't really support the CS:S Beta.
It only can be installed in those computers which RAMs are 3.00GB to 4.00GB. And I'm not really sure if GB is bigger than MB or MB is bigger than GB. I really suck at that, I know.
I wish my CPU is like my brother's. His one is 4GB, I checked when he got to the restroom. I really hope one day I got another RAM for my computer. Hmm...
If anyone could help, comment. You know, I've seen what it looks like inside a computer before. So there are 3 slots for the RAMs available. I think only one slot is secured with a ram. Really need to put one more ram into the second slot.
