What RAM is good for my ASUS P4P800 VM MB ?

[Mattijn30]

Hi.

I have an asus P4P800 VM and i want to increase its memory size. I really dont care about getting a complete new computer, and i really want to upgrade this oldie 🙂

Can someone tell me (because i lack the knowledge to find out myself...) what memory modules i should look for in this old computer? I found out that i need DDR1.. Is that correct??

This is the first time i use tom's hardware site so please be gentle ;-)

Go to the following link, scroll down to the "Manual" bullet point, expand it and download the QVL (Qualified Vendors List). That will show all the memory which they actually tested. Memory by other vendors may work but ASUS actually tested these.
Support For Motherboard P4P800-VM

Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards can be very sensitive to this.
That is why ram vendors will NOT support ram that is not bought in one kit.

You want documented ram compatibility. If you should ever have a problem, you want supported ram.
Otherwise, you risk a finger pointing battle between the ram and motherboard support sites, claiming "not my problem".
One place to check is your motherboards web site.
Look for the ram QVL list. It lists all of the ram kits that have been tested with that particular motherboard.
Sometimes the QVL list is not updated after the motherboard is released.
For more current info, go to a ram vendor's web site and access their ram selection configurator.
Enter your motherboard, and you will get a list of compatible ram kits.

CPU-Z will identify what ram you currently have.
If you want, try to buy the exact same voltage, speed, and timings that you already have.
No guarantees though if you just add ram.
