4c 55 0d error need help!

[ShwarzNoir]

Hey guys im currently having issues with my ram slots

im not sure if this is a software or hardware problem 

so here's my story

my computer boots fine if i populate Slot 1 and Slot 2 but if i try to populate Slot 2 and 4 it keeps saying "4c,55,0d "

Slot 1 and 3 does the same thing also populating all the slots does the same thing 

things that i have already tried are:

1.check my ram sticks are fine (which they are)

2. clear CMOS

3.check for bend pins on the CPU ( didnt find any)

4.clean the ram slots 

sadly nothing works.

 

specs:

Mobo Msi Z270 gaming M7 Bios ver. 7A57v13s

GPU Msi 1080 ti gaming x

RAM Corsair VENGENCE RGB 16gb x4 CMR16GX4M2C3000C15 currently using 2

CPU 7700k

Same problem. Idk exactly what fixed it but i tried using only 1 ram stick in all slots one by one and then with the other stick.

Then it booted and later both ram sticks started working fine.
