Man you were right! I' ve removed the fan from the cpu and cleaned the thermal compound from the corners of cpu and this fixed the problem. I'd never thought this coud cause a memory failure! Thank you very much.

Make sure the contacts are clean and that the substrate (the green PCB with the
contacts on it) is not warped or bent. Looking at your pics it doesn't seem bent. I do see some dirty looking contacts, use some IPA (isopropyl alcohol) and a cotton bud to clean them all nicely so there is no discoloration. Check the CPU socket on the motherboard too and make sure there are no bent/misaligned pins. |

This is the cpu. Do you mean there should be something wrong with cpu geometry?

Check to make sure no pins got bent in the socket. If there are no bent pins make
sure the CPU substrate isn't bent. I had a 6600k that had a corner bent up and it resulted in only one working memory channel. After clamping the CPU between 2 blocks of wood with some creative shims in a vice I was able to carefully straighten it and it's worked fine ever since. Edited by Xaltar - 14 Aug 2020 at 8:12pm |

I had a z97M with a cpu G3258 and 4x2g corsair XMS3 (CMX4GX 3M2A 1600 C7) in Dual channell = Everything works fine and also overclocking cpu to 4ghz
Today i replaced the cpu with i5 4670K and the mobo didn't started. I removed 3 memory stick and the mobo started again. Also the mobo works with 2 sticks NOT in dual channell (a1 + a2) like in picture:  Each other combination fails it seems the mobo reject the dual channell mode and also b1 + b2 in singol channel doesn't work I'm running the last bios. I've loaded the defaults bios settings before replacing cpu and after. I've booted the mobo with all memory slots empty to reset memory motherboard settings. |
