Exactly the same components accept for the MB.
Corsair VENGEANCE® LPX 32GB (4 x 8GB) DDR4 DRAM 4133MHz C19 Memory Kit
SPD Speed 2133MHz
These were purchased in 4 32GB sets, 2 sets installed on each MB. This memory is on the tested list for these boards from ASUS, and were purchased in sets as per the ASUS stipulation.
Neither board is overclocked “by hand” but only with the built in ASUS “AI Tuning”. I suppose I could manual turn off all tuning.
It is quite strange as both MBs run the same firmware, same chipset, same processor, etc.
