Hi Pirilio,
Do you mean if enable xmp1 or xmp2, it will stuck at DRAM LED and no boot, but it can boot with bios all default settings(no OC) on bios 2004?
In addition to xmp, do you adjust other bios settings?
Looks like the ram you use is 2 sets of (8Gb x 2). Please try the same set(2 ram sticks) in DIMM_A2 and DIMM_B2 first.
If the result is the same with 2 sets, please try each ram stick in each ram slot one by one to see if it works.
Thank you.
