Two sticks of 2GB = 3072 why? (in yellow or black slots)

Two sticks of 1GB = 2048 ok, in the same slots so I presume there cannot be anything wrong with the slots.

Each stick has been tested on it's own and bios reports the correct stick size.

All sticks installed Windows 7 64bit says installed 6GB (5GB usable)


Motherboard ASUS P5B deluxe
2GB DDR2 6400 CL6
1GB DDR2 533 CL4

All sticks have been loaded on the motherboard one at a time and all sticks reported the correct memory size of 1GB or 2GB.

Windows 7 64 bit

The board has a built in overclock that is set to number 1 of 2 (The board is second hand) could the previous owner have set some memory timings that stop the 2GB sticks from working correctly?

Restore your MB to default
see if that helps. If not download and boot a live disk (Ubuntu and see if that gives you the same issue) if it does the fault lies on you MB config if not then it's Windows

Going to investigate how to get the board to go to default. Some comment that you remove the cpu and then the boards goes back to factory settings. I'm not going to remove the cpu as that is too much work.
I notice there are much newer BIOS downloads available at ASUS so I think I will use one of those.

Thanks for the suggestions.

You don't need to remove the CPU at all, There are setting in the BIOS, failing that mover the CMOS reset jumper or just remover the CMOS battery

I was really hoping you wouldn't of tried that!

ok if you are lucky we can save this.

What media did you have the BIOS update on? you need it on a CD or USB not Hard drive. Put that media in and unplug you PC.

Locate the BIOS reset jumper and remove it. Remember how it was positioned you will need to put it back the same way.

Now Pray

Plug the PC back in and turn it on it should go through it's normal boot sequence and then try to update again. Don't touch anything unless it asks!

If it manages to update then it's OK to reboot

If it won't turn on at all you may have damaged you MB, let me know.

I get no post sounds and I presume this means it cannot even read a flash drive.

Looks like the board is broken ;(

If you have read this thread to the bitter end you know I toasted the motherboard :(
Now I have a second-hand replacement board and have found the answer to the problem of missing memory.

Because I was using the PC as a test server and did not need a powerful graphics card I had mounted an old NVIDIA 64MB PCI card.

It appears that because the card has so little memory it was using the PC's memory. Windows 7 64bit says "installed memory 6GB"!

Now I have inserted an old 512MB power hungry gaming graphics card I now have no missing memory.

Note: the replacement motherboard was tested with the 64MB and did have the same loss of memory as the toasted one. The BIOS versions are not the same.
