Gigabyte Z170XP-Sli and Asus H270-Plus (for testing)
Intel i5-6600k
Gskill Ripjaws 2x8GB 2133Mhz
Some 500W BeQuiet PSU (which is pretty old but was working just fine for high power draw under oc)
So i'm really confused with this issue. Whenever i put my Ram in Dual Channel (1/3 ; 2/4) the pc does not even post. If in (1/2 ; 3/4) it works just fine. The weird thing is this setup worked in dual channel for like 2 years and suddenly after reseating the cpu for a cooler change it stops booting. Since then i reseated the cpu multiple times with no success. Then i noticed that my 2 lower USB Ports on the back of the Mobo stopped working more or less. Whenever i plug something in it disconnects and reconnects constantly until i pull the usb out. The other back USB also stop working under high usage, e.g. games and start dis/reconnecting. So i thought it was a mobo fault, but today i tried a brand new mobo with the exact same ram problem. I didn't have the time to check for the usb problem tho.
What could even be making problems with the RAM und USB Ports? The CPU or PSU or something else entirely?
