- What is the speed (frequency) of the old and new RAM?

- Are both old and new configurations of RAM just one stick? As in old board setup had one stick, new board setup had one stick (or was supposed to)

- Are you mixing old and new RAM together?

If you upgraded your Motherboard and didnt do a completely Windows reinstall that is probably the issue. Also what is the exact RAM you are using including the speed?

current ram is 1 stick of 8gb kisnton value ram 1066mhz new ram was corsair vengance 2x 2400hz 4gb

Where are you getting that 1066MHz from? If it's CPUz you double that number to get to 2133MHz. DDR4 RAM doesn't run at 1066MHz effective. I think your Kingston is DDR4 2133 and you can look in BIOS settings to confirm. At worst you lose a bit of speed at dual channel mode.

The Corsair ones should work in the new board. What happens when they "dont work"? Are you failing to boot or is there problems in Windows?

- The 2 sticks should be in slots 1+3 or 2+4, with slot 1 being closest to the CPU. Try both these setups.
- If system won't boot, try one stick at a time in slots 1 or 2.
- OS reinstall is essential for motherboard upgrades.
