Hello, I recently was completing RAM testing with some of our ThinkCentre M Series computers. Once I completed the testing, I put the same amount of RAM back into the machines. It functions fine and shows up in BIOS and Windows, but the message "error 0164 memory size decreased" simply will not go away. I've tried removing the CMOS battery and various other things (there are previous threads with similar issues, none of the resolutions worked for me though). Any ideas?
