So I have, what some may call "vintage", an EVGA Z68 with an i3770k and 4 sticks of 4GB Corsair Vengeance running 64 bit Windows 7 Pro SP1 and latest updates. Where does it show I have 8GB of ram? In my BIOS My Computer properties Task Manager CMD Line systeminfo | findstr /C:"Total Physical Memory" shows 8,159 MB Where does it show I have 16GB of ram? CPU-Z (shows memory size 16GB and states each slot populated) 3DMark 11 (Test results show I have 16GB) Speccy shows RAM 16GB Any clues what could be causing the conflct? I am not sure it even matters since some programs can recognize the 16GB. Ive tried swapping out all 4 sticks between different slots and have loaded BIOS defaults but still the same thing.
