There is at least one discrepancy in the supported memory list on the Asus support site for the ROG Maximus Z790 Hero motherboard. The part number given for the G.SKILL DDR5 7800 DIMM does not agree with the timing in the table, see image below. When I go to the G.SKILL website, they only list the F5-7800J3648H16GX2-TZ5RS. There isn't a F5-7800J3848H16GX2-TZ5RS. So I am going to assume the F5-7800J3648H16GX2-TZ5RS is the correct part. I will confirm this with Asus. [ATTACH=full]156[/ATTACH]
