Asus p5 vdc-x motherboard not recognizing ddr2

From http://www.motherboard.cz/mb/epox/EP-4PDA5.htm:

4 DDR modules for DDR 333/400 dual channel architecture

If you have 4 ram slots and only 2 are filled, you just need to match the speed of the two you currently have, they can be any size(500mb, 1gb, etc). I'm not sure you'll be able to find DDR ram anymore though.. and NO you cannot use DDR2 ram.

means ur board only support max 1gb ram can u give me detail of ur system means details of processor,motherboard etc.... write it on a testimonial ill definately let u know

HI it sounds like a speed issue,check your
motherboard info for support or if you
have no manual download it from asus site
check for ddr2 support via the manual

regards john sykes

this board supports only ddr1

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.

i think you need a same brand of 256 for it to work? and when you buy something for your computer make sure that the one you both is the same brand or code with your 128 for example you have 128 ddr2 sdram so you can only upgrade it with 256 ddr sdran or 512mb,1gb,2gb ddr sdram.

Hi KF27,

Your system has and supports PC SODIMM DDR RAM with a MAX support of 1GB. You currently have 512MB of RAM (2x 256MB), so your only option is 2x 512MB of RAM..

I hope this helps you out!

If your PC boots up successfully and load windows then its mean that RAM is working fine... There is some problem with OS settings.. So at XP booting press F8 for start-up menu and select Last known good configuration... Hope it will work...


Please Rate .... Thanks.

the size of the ram is not enough, try increase the size of the ram.

does your mother board ddr2 compatible? do you have the manual of your motherboard? because there are brands listed in your manual which are compatible. if you have an existing ddr installed temporarily uninstall this and try this ddr2 512mb alone and let it run, if a beep beep sound occurs that means this is not compatible with your computer. remove this and bring this together with your ddr that work to your supplier, ideally the cast latency timer of these should be the same including the brand. hoping that this will help you
