I just installed 4GB of memory in my MSI 865PE Neo2-PFISR mainboard and only 3GB (approximately 3144000KB) are reported present by the the BIOS.
The 4GB are distributed in 4 DDR400 1GB DIMMS, and all sticks are from the same brand/model. I previously had 1GB distributed as 4 256MB DIMMS so I am sure there is nothing wrong with any of the slots.
By alternating the DIMMS around the slots and making several tries with only 3 DIMMS connected, I have also determined that all 4 DIMMS are working properly.
The value in KB reported by the BIOS is exactly the same with either 4 or 3 DIMMS installed, however with 4 DIMMS installed BIOS correctly reports Dual Channel presence, so some level of the BIOS is in fact recognizing the 4 slots are in use.
From the gathered data I can only assume there is something deficient about the BIOS. My version of the BIOS is the latest available, 3.A (as reported by the boot screen) or 3.0A (as reported by the MSI live update). It dates back to 09/29/2004.
I would like to know how this problem can be resolved. The specifications for this board claim it supports 4GB of memory, so that is exactly what I expect it to support, nothing more, nothing less. 1GB is what had installed in my system up until today, so I am definitely not going to accept being deprived of that amount.
Any clues?
Cheers
