I just received my board and have been trying to get it to post all evening.
I believe it has gone through memory training - at least it did a few cycles with reboot in between (91-93-95?).
I have used the BIOS flashback to update to the lates (10.01) BIOS.
On cold boot it looks very good, but then it hangs a little while on d6 before it changes to 02 and stays there. I can’t find any information about the post code 02 other than a suggestion to reseat the cpu and clear cmos. That results in a new memory training and reboot and then 02 again. I have checked all the screws holding the mounting mechanism, made sure that the carrier frame stayed within the rails when mounting the cpu. No visual defects on the socket and cpu.
