It is MSI H310M PRO-VD, my ram is working on another system at both 2133 and 2400mhz so seems like something's wrong with the cpu. I'm probably going to return this cpu and buy it from somewhere else.
So, it cannot possibly be your board or memory, right? It must be the processor, right?
Everyone wants to take the easy path, which is to blame the processor. Even if the memory works in another machine, TRY DIFFERENT MEMORY.
Returning the cpu and buying from somewhere else? You mean getting the same cpu from another source, or a different CPU?
I sent the motherboard to service and they said they updated to latest bios, tested everything and it was all functional.
I only have 1 stick of Ddr4 ram with me right now.
And I meant buying the same cpu from another source.
