I've got a Rampage IV with i7-3930K that I has 32GB of RAM plugged in. Only 16GB show on the BIOS. All parts are used. 630 Watt Thermaltake power supply. I have plugged in all of the power ports on the MB.
(4 * 8GB) 1600MHz DDR3 Corsair V\engeance.
RAM is plugged into slots A1, B1, D1,C1
I know the RAM is 8GB because when I plugged into one slot 8GB shows up on the BIOS.
I have reset the BIOS by pulling the battery.
Please throw me a bone. I plan on using this BOX for a Linux VM server. I've got a low ed video card in it.
Solved by moving ram to c1,c2,b1,b2 This is a used MB and I believe 4 RAM slots are defective. Additionally I updated the BIOS using the WHITE usb slot method. I plan to update the bios again to the 2014 update.
I installed Debian 9.5 and plan to run windows 10 using KVM.
