164 memory size has changed

[WaelAbdrabbo]

Hello,

sometimes I got this message when I boot up my workstation 

"164 memory size has changed.
  The system memory size is different from the last setup"

then I open the bios setup to check wich RAM making this issue, sometimes CPU0-DIMM3 or any ram slot can't read the memory and I have to remove it and reinstall it to make sure the slot can read the memory correctly.

I'm really confused about this issue, sometimes I didn't get this issue for months and sometimes every day.

I installed 4x4GB and 4x2GB RAM and actually this issue related to the 2GB RAM.

Thanks,

Wael.

I tried today to make a test on the RAMs and here are the results,
