Board: MSI k9a2 Platinum
CPU: AMD Phenom Quad Core @ 2.5Ghz
Memory: 4 Sticks of Patriot DDR2 rated for 1066mhz
OS: Win 7 Home Premium
I built this system in 2009, it has run two sticks of 4Gb Patriot Ram that entire time. The bios does a memory count on each boot, it has always shown 8Gb total, Windows 7 has always shown 8Gb of RAM. I have not made any changes to the bios at this point.
Problem as of this week, the bios count and Win 7 shows 4gb of ram when TWO 4gb sticks are installed in Slots 1&2. MSI states to populate slots 1&2 or 3&4, or all 4. This system has been running fine for 4 years with slot 1&2 populated with the above ram.
I even took out one stick and left a single 4gb stick in slot 1, bios check shows 2gb and so does win7. I've swapped them from 1&2 slots, to 3&4 slots, same issue,, half the ram. I ran Windows memory diagnostics tool and it reports no issues. I've set bios to default, disable the msi splash screen so I can see the memory check, and re-enabled the boot from RAID so I can boot off the raid. This made no differences, still only half the ram shows.
I now have 4 sticks of the same 4gb Patriot DDR2. When all 4 are installed, only 8 of the 16gb shows in the bios check and in windows. I am currently re-running the windows memory diagnostics tool with the 16 gb installed.
No matter the amount of ram installed, only half of it can be accessed. Is there more than one bus for the memory? Could it be that one of the paths for the ram on the motherboard is bad???
Sorry for being so long, I'm trying to put the maximum amount of info out there.
