Anyone know why an ASUS PTGD1-LA motherboard will only take memory in slots A1 and A1 or A1 and B1 but not anything in B with both in A filled? Brand new memory.


The board has specific requirements for memory. Here's the Memory Configurations :

  • You may install 256 MB. 512 MB and 1 GB unbuffered non-ECC DRR DIMMs into the DIMM sockets using the memory configurations in this section.

• Installing DDR DIMM. Other than the recommended configurations may cause memory sizing or system boot failure.

• In dual-channel configurations, install only Identical (the same type and size) DDR DIMM pairs for each channel.

• Always install DIMMs with the same CAS Latency. For optimum compatibility , It Is recommended that you obtain memory modules from the same vendor

• Double-sided x 16 modules are not supported on this motherboard.

• Due to chipset resource allocation, the system may detect less than 4 GB system memory when you installed four 1 GB memory modules.

For dual-channel configuration you may:

install identical DIMMs in all four sockets

• install identical DIMM pair in DIMM_A1 and DlMM_B1 (blue sockets) and identical DIMM pair in DIMM_A2 and DIMM_B2 (black sockets)

• install same size DIMMs in DIMM_A1 and DIMM_B1 (blue sockets) and another same size pair in DIMM_A2 aid DIMM_B2 (black sockets)

Hopefully this will help understand how to install the new memory.

Thanks Mark

Se7520bd2 - I installed 4 GB of ram (2 sticks) I added later another two ram chips the same mobel. The M/B is not recognizing the 2nd set? My Emial is

1) unless your operating system is 64 bit, your computer can only use 3 GB RAM maximum, so 4GB is a waste of time.

If you already had two identical sticks of RAM, chances are your BIOS is setup to recognise twin channel RAM is it has larger bandwidth so it is quicker. To use two channels your RAM must be identical in both channels, clearly if 3GB is the maximum you have a lopsided config and you have to swap the BIOS to single channel RAM.

Of course if you have already checked the BIOS rather than windows, and it still only sees 2GB RAM, the problem is a different one.......

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.

1gb shows 512mb only

Your mobo is quite old and its chipset can only support a maximum of 512MB PER SIDE (technically called a bank) of a memory module. I would guess that your 1gb memory module has 8 chips that are all located on one side of the module, putting all of the 1 GB on one bank. Thus, only 512MB of your 1 gb RAM is detected and usable by your motherboard (the remaining 32 mb is most likely being used by your onboard video). You'll need to find a double sided 1 gb memory module (usually 8 chips on each side).

This motherboard only support DDR type of RAM up to 4GIG , 400 MHz • 333 MHz this are the support speed of DDR RAM, so you can go ahead upgrade up to 4 GIG of RAM and that will make your computer very fast...

Upgrade from 512MB to 1GB

The specs on the memory are correct, so you purchased the correct type of memory for this motherboard. If your getting no video when you power on with the 1gb stick, I would be willing to bet the 1gb stick is bad. Can you return it and try another stick?

Motherboard ASUS P5RD1-VM ram problem

More people should complain with Asus support. Checking Asus forums, you'll find there's an obvious problem with a PCI-E video addon + 2 used memory slots. In my case, I had 2Gb (1 + 1), mb with bios version 1104, and it worked fine; when I installed a new PCI-E card, the system was very... very sluggish. Now I have uninstalled 1 memory, I'm using only 1Gb of RAM with the PCI-E card, and it's working well.

Again: checking Asus forum, this is a reported problem, and a bios bug... Asus should release a new bios version, but they seem not to bother, as this is a relatively "old' mb...
