Hello, i have problem with my Ram sticks, the problem is when i boot up my pc with 2 ram sticks is not booting im getting black screen, my ram is HYPERX FURY 8GB DDR4 2666mhz and my motherboard is MSI H410-M PRO
When i remove one stick of ram it boots up perfectly, both rams works single but together not good pair.
how i can solve this?

Did you purchase the 2 sticks as part of a kit for a single price?

Or did you purchase each stick individually?

2 sticks with a total of 8 combined?

Or 2 sticks with a total of 16 combined?

I bought them separately 2x8gb

Do both your DIMM sockets work when you fit a single memory stick in the motherboard? If not, your problem is socket/CPU/memory controller related, not RAM related.

You bought the DIMMs separately so they do not constitute a matched pair. They may well have different memory chips and/or different timings, which could explain why they don't work together.

Check the memory chip manufacturer(s) and type(s) with Thaiphoon Burner.

Check your memory timings with CPU-Z.

If both of your DIMM sockets are working, the best option is to buy a matched pair of DIMMs and ditch the old RAM.

Intel is usually quite tolerant of mismatched ram.

Another cause can be a bent pin in the cpu socket.
Various ram issues are typical.
It is all too easy to do if you did not drop the cpu in cleanly and had to smoosh it around to get it seated.
If that is the case, use a needle to try to bend the pin back in position.

The CPU is never removed from socket, the pc is working perfectly but with only one ram stick, at one slot (first or second slot) i put the ram stick it works but both can't work together.

Has this problem been present since day one?
If not, then the socket is ok.
But, if this problem has been present from day one, you should check the pins for a likely cause.
