Hello, everyone. I believe this to be the proper forum for this topic, and I failed to find any other topics to answer my question, under a quick inspection.

Here in lies my question.

I'm interesting in purchasing more RAM for my computer. However, I'm worried about buying a chip that is not compatible with my system.

I do know a little bit about this topic, but I don't have all of my bases covered.

The chip I had found a nice chip to buy, but am unaware what one of the specifications on it are.

The Chip is a PNY 256MB PC2700 DDR 333MHz.

I know my RAM slots are DDR, and I know 256MB is the amount I want. However, what concerns me, is the PC 2700.

I'm not quite sure what it means, although I believe it has something to do with the data transfer rate, but I am worried that it may cause some sort of compatibility issue.

I'm sure the more information I can provide the better, and so, my computer is an HP pavilion in model, runs with a Celeron 2.0gHZ processor, has two RAM slots (one open), 256 MB DDR RAM, and is just barely over one year old.

And so, I ask, could the "PC xxx" spec cause problems with compatibility, and if so, is there a way to check and see if it is compatible?

Thanks in advance.
