Type: SDRAM 133mhz
Max: 1024MB (1GB)
This type memory does not usually have to be equally paired. You should be able to use a 256MB and a 512MB to combine for 768MB if you can't get access to two 512MB sticks.

Not dangerous at all and you can get some great prices along with pretty cheap shipping.

Ebay is like a yard sale except you have rated sellers. There is always a risk, but find a seller with a high rating (97% or above is usually where I look), and you should be fine. Used RAM is usually cheaper so it might be a good idea. Worst case scenario you get bad RAM. As long as the RAM looks in tact and the contacts look good it won't harm your computer.

Memory is expandable to 1 GB, employing 64/128/256/512-MB 64-bit
industry standard soDIMMs (Small Outline Dual Inline Memory
Modules). The computer supports SDRAM (Synchronous Dynamic
Random Access Memory).
There are two memory slots on your computer, one of which is
occupied by standard memory. You can upgrade memory by installing
a memory module into the available slot, or replacing the standard
memory with a higher-capacity memory module.

What exactly is the model number? Some of the 740 series can only take up to 512MB, while other can do 1024MB max. The model should be something like C312XCi or C314XMi

Hmmm...that number doesn't seem to come up with anything. Are you sure there's not a model number on the bottom that start with a C______, like the ones posted above?

You could also go to Start->Programs->Accessories->System Tools-> and click on System Information to get the model. It should be listed in the Summary page next to "System Model"

Not familiar with how to use that. You really need to find out what model number it is so that you don't waste your money on extra RAM if the PC won't even recognize it.
