Could you please help to check if it still stuck at error code 55 after update Intel ME v126.96.36.1995 from our support site?
Updated the BIOS to 2103 and planned to get a 13900k to slap in, but after restarting got a stuck error code 55.
Took out the Corsair DDR5 from slots A1/B1 and restarted and it posted no issues. Tried putting my RAM back in those slots to fill up all 4 and went back to error 55.
Prior to BIOS 2103 I was on 1720 with no issues using all 4 sticks. From what I understand also there's no going back to previous BIOS.
Anyone else having the same issue with RAM? Is this a Corsair issue or an issue now with the Extreme board? I've had nothing but issues with the Corsair DDR5 Dominators but usually it's lighting/iCue related.
