MSI z270 Titanium Board
G. Skill Ripjaws 4 x 8gb 3000mhz
I7-6700k

Runs fine with two sticks of ram in first two slots only. If I had any configuration of 3 or 4 sticks, won’t post (codes 00-4c-55-0d). Code 55 says memory not installed. Any ideas?

Also. Have a m.2 Samsung 960 250gb and a 3.5 pny 960gb SSD. Sees the SSD in bios but not shown in boot order (just want as storage drive anyways) but not in windows either.

Help appreciated!

could be bad dimm slots

or bad ram sticks

Also for the M.2 to be a boot drive you need nothing else plugged in.
