Question about ASUS P4S800D-X (610839122325) Motherboard
When I started using this MB I had 2 512mb PC3200 DIMM's installed in DIMM A1 [blue] and DIMM B1 [blue] these worked with no problem.
Later I decided to add more memory and as I only change 1 area at a time when making changes, I removed the 512mb DIMM's and installed 2 1gb PC3200 DIMM's in their place at DIMM A1 [blue] and DIMM B1 [blue] . They worked fine.
Then I installed the 2 512mb DIMM's into DIMM A2 [black and DIMM B2 [black]. When I started to boot up the monitor showed nothing at all except it's built in check saying the monitor was OK. Thinking I might have damaged the 512mb DIMM's I removed all the DIMM's and installed the 2 512mb DIMM's into DIMM A1 [blue] and DIMM B1 [blue] and they worked with no problem.
I cannot make the computer work with all the DIMM slots filled. I have heard that others had the same problem. What's the fix?
Reset the BIOS using the motherboard jumper before booting into Windows.

You can install 128 MB, 256 MB, 512 MB, and 1GB DDR SDRAM DIMMs into the DIMM sockets using the memory configurations in this section.
• Install only identical (the same type and size) DDR DIMM pairs
using the recommended configurations.
• Make sure that the memory frequency matches the CPU FSB
(Front Side Bus). Refer to the Memory frequency/CPU FSB
synchronization table on the next page.
• This motherboard does not support double-sided 16-bit DDR DIMMs.
• Do not create a three-DIMM configuration in dual-channel mode. The
third DIMM is ignored in the dual-channel operation.
