    I have P8P67 PRO Rev 3.1 mobo. I have 4x4Gb memory modules and early BIOS and Ubuntu shows I have 16Gb of memory. Some time ago I have added M2 SSD connected to PCI Express card and updated videocard to GeForce 710 (GK208B). I noticed that BIOS and Ubuntu show I have only 8GB of memory (but BIOS detects all 4 modules and output information of each module). I have removing my PCI Exrpress card, change back videocard to old one, change memory modules in memory slots, output and back CPU, resetting the BIOS... no luck (
    I have check each memory module in another mobo - each of them is working.
    installing only 2 memory modules each of 4Gb show only 4GB in BIOS o_O
    i have latest BIOS version (3602).
    what could be wrong and how to solve this problem?
    thank you
