RAM help don't know what RAM i need for my comp!?

im looking to get some more ram and right now im looking at newegg.com and there are lots of different options.

This is what i know about my ram: DDR2 Single channel 1GB

DRAM Freguency 301.4MHz.

On newegg it has options like:

DDR2 1000 (PC2 8000)

DDR2 1066 (PC2 8500)

What does the 1000/1066 mean and the PC2 8000/8500 mean? Where can i find this on my computer?

I have the program CPU-Z but i dont know much of what any of it means.

Also on newegg it has

240-Pin DDR2 SDRAM

240-Pin DDR3 SDRAM

What does anythis mean too?

And how can i found out what my RAM has on this?


Oh yea its a desktop as well

    It's odd that it reports the memory is at 301MHz. It should be 333MHz. DDR2 667 what you want to get. DDR stands for double data rate. DDR2 667 runs at 333.5MHz, 333.5MHz * 2 = 667. The same for DDR2 1066 (and all the others), 533 * 2 = 1066. It wouldn't hurt to put higher rated memory in the computer (higher than DDR2 667), but there wouldn't be any point since you wouldn't be running it at the higher speed.

    In CPU-Z, click the tab that says SPD. It will show you the capabilities of the ram you have installed. The maximum speed listed there is the type of ram you will want to upgrade to.

    PC2-5300/5400 = 667mhz

    PC2-6400 = 800mhz

    PC2-8500 = 1066mhz

    These are the most commonly used and supported ram speeds.
