Ram not compatible with Mainboard, i bet my balls!
your mainboard
- Supports DDR4 2400/2133 non-ECC, un-buffered memory*
- Supports ECC UDIMM memory modules (operate in non-ECC mode)
your ram
- Standard DDR4-2133 (PC4-17000)
it should look like
Standard DDR4-2133 PC4-17066U -> the U stands for UDIMM
Could that be it?!
My Ram: Kingston KVR21R15S8/4G RAM 4 GB 2133 MHz DDR4
ECC Registered CL15
DIMM 288-Pin
Ordered a new RAM stick which should arrive today: Crucial DDR4-2133 8GB RAM (which should be UDIMM).
If this is it I'll buy you a beer!
