As reputable if not more so than Amazon,

Newegg.com - PNY Optima 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Desktop Memory Model MD4096KD2-800

$4.00 a kit cheaper, and faster speed to boot.

If you want slower that is up to you. The page for your motherboard is down at Asus at the moment, but your motherboard actually supports up to DDR2 1066,

but it is definitely not worth the price difference for the little bit extra speed.

By the way a couple of things to consider if you do go to 8 GB,

1. If you plan on upgrading the rest of your computer any time in the near future and had intentions of moving the memory, you won't be able to as all AMD and Intel boards now take DDR3.

2. Don't be surprised if you do take it to 8 GB and this happens,

The system memory that is reported in the System Information dialog box in Windows Vista is less than you expect if 4 GB of RAM is installed

Quote:
Note When the physical RAM that is installed on a computer equals the address space that is supported by the chipset, the total system memory that is available to the operating system is always less than the physical RAM that is installed. For example, consider a computer that has an Intel 975X chipset that supports 8 GB of address space. If you install 8 GB of RAM, the system memory that is available to the operating system will be reduced by the PCI configuration requirements. In this scenario, PCI configuration requirements reduce the memory that is available to the operating system by an amount that is between approximately 200 MB and approximately 1 GB. The reduction depends on the configuration.
Basically means that you will have somewhere around 7 GB available; could be a bit more or a bit less; depending on what is connected to the motherboard (which is pretty much everything from the video card to the sound card, etc).

that's where i buy stuff and i feel more safe.
i will buy a whole new set to get to 8G of ram since each solt can hold max 2G.
please and thank you guys for helping me.

is this the right ram?
Amazon.com: PNY OPTIMA 4GB (2x2GB) Dual Channel Kit DDR2 667 MHz PC2-5300 Desktop DIMM Memory Modules MD4096KD2-667: Electronics

45$ for the 4G of ram
You should be fine with 2 sets of either:

Amazon.com: Corsair XMS2 4 GB (2 X 2 GB) PC2-6400 800 MHz 240-PIN DDR2 Dual-Channel Memory Kit - TWIN2X4096-6400C5: Electronics

OR

Amazon.com: Crucial Technology CT2CP25664AA800 4GB 2GBx2 240-pin DIMM DDR2 PC2-6400 Memory Kit: Electronics

PC2 6400 will give you a little more speed than your current ram & your motherboard will handle it easily.

Just remember when you get the sets, be sure to install the memory modules in the correct dimm slots. I'm not sure about your motherboard requirements for this. Many motherboards require you to install one set in dimm slots 1 & 3, and the other set in 2 & 4. Otherwise you will not be taking advantage of the dual-channel advantage. (See my edit below, - it's 1&2 and 3&4).

Another note - You can go with PC2 8500, but on rare occasions some motherboards have intermittent issues when running the fastest ram & maximum capacity that they are advertised to handle.

Edit - I just checked your motherboard manual & you need to install one matched ram set in dimms 1 & 2, and the other set in 3 & 4

I also noticed a note in the manual about limitations on 8 GB of PC2 8500, so I'd definitely go with the PC2 6400 to avoid any possible headaches!
