Compatiblilty, expert opinion please

Hi.

That RAM can works in your mobo. Your mobo have 4 slots and support max 4GB of 667 or 533. So, you can go with that RAM without problems.

Now, the voltage isn't a problem, usually DDR2 is 1.8V or 2.0V. Don't worry about that.

Just try to get 2GB or more.

For any ram you are considering, do your own homework.
Go to the ram vendor's web site, and access their configurator.
Corsair, Kingston, Patriot, OCZ and others have them.
Their compatibility list is more current than the motherboard vendor's QVL lists which rarely get updated.
Enter your mobo or PC, and get a list of compatible ram sticks.

Here are a few links:

Cpu performance is not very sensitive to ram speeds.
If you look at real application and game benchmarks(vs. synthetic tests),
you will see negligible difference in performance between the slowest DDR2 and the fastest DDR3 ram.
Perhaps 1-2%. Not worth it to me.
Don't pay extra for faster ram or better timings unless you are a maximum overclocker.

A 4gb ram configuration of 2 x 2gb is superior to 4 x 1gb.

cool thanks, didn't know you could specifically look at the ram manufacturer's sites, although mine is Play.com, wonder which is their manufacturer O.o
