What to believe? Bios-CpuZ-Task manager?

[stoanee]

This isn't really troubleshooting but, I have 16gb ram installed (4x4gb) and it shows properly in bios & Cpuz. When I go into task manager>performance it always shows 12gb. WTF? I am using Win7 pro And have just changed from 1600 to 2133 mhz ram. The 1600 ram also showed as 12gb. Should I be concerned?

Look for a "Flexibility Option" or "Memory Configuration Protect" in the memory/OC area of the BIOS.

I had a problem like this with an MSI board, it was a known problem that was never patched by MSI. They even sent me a few beta bios to try. Bios showed 16GB but windows only showed 14GB if I remember correctly.

Try the RAM in different slots if you can. When my RAM slots were damaged it would show 3x2 6GB but only pick up 4GB.

If the RAM slots look OK (no bent pins), then try re-seating your CPU since sometimes it doesn't sit right on the LGA and contact the pins for some of the RAM channels.
