Hello. I've just purchased;

z490 Phantom gaming 4
comet Lake i5 10600k cpu
Gskill trident f4-4000C18D-16GTZR

The memory individually past test at 4,000 MHz at SPD timings and voltage. In dual Channel it fails. I've tried reversing the memory in the slots compatible with two sticks. All other settings are set to auto. I'm testing with them memtest86. The memory and cpu is listed as compatible for the motherboard on the ASRock site. Is the memory bad?
