Cypre

So when I first got it. I put it in with gskill ripjaw ram, and I also put the fury ram in with no other ram both did not boot up my pc

So I just received 8gb of HyperX fury RAM and I installed it into my motherboard, but my pc won’t boot up. I bought the product from an eBay seller saying that it was pulled right from an HP Omen 30L. But it won’t work with my motherboard. motherboard: gigabytes z390 UD cpu: intel i5 9400f
