Your motherboard can take DDR or DDR2 RAM modules.

Crucial says: "Each memory slot can hold DDR PC2700,DDR PC3200,DDR2 PC2-5300 with a maximum of 1GB per slot." No sense getting 4GB since the max is 2GB.

You can get higher speed RAM (PC2-6400) because it is backward compatible.

I would go with the 2 X 1GB Corsair from the ones listed.

Or consider the options on Crucial's site. See this page:

Two 1GB modules of DDR2 PC2-5300 run about $34 US.

(PS. Your 450W power supply will handle about anything.)

    Forgot to can't mix DDR and DDR2. You must use one or the other.

    Also, if you go to the Crucial site, click on "Show All" to see all of their upgrade choices.

    Thanks for using Fixya.

Can asus p5gz-mx support 2gb kingston 800mhz ram

Click here to view the Specifications of your computer mainboard.

Unfortunately only 2 x DIMM, max. 2GB, DDR2 533/400 MHz memory modules are supported.
Meaning that it is not possible for the 2gb kingston 800mhz RAM to run, according to the Specs.

Sorry to inform you of this fact!

Ram assurance

The schematic layout of the P5VDC-MX on the user manual shows that there are 4 DIMM banks, set as 2 X 2 rows, 2 DDR2 and 2 DDR.

The user manual explicity states:

I am running different frequency modules without any problems. With the info above provided by ASUS, it may be possible that a fix could be available with a BIOS update. Otherwise, you can opt to use a lower capacity RAM along with your 1GB Corsair.

Hope this helps.
