> With four 6000 sticks I just flat out can't get more than a 12 hour stable prime95, even at jedec-4800 certified speeds. I can't even boot at 6000. Note that while your memory sticks may be rated to handle JEDEC's DDR5-4800 speed, and faster with XMP profiles, Intel's memory controller is only rated to operate at DDR5-4000 with two single-rank modules per channel, and DDR5-3600 with two dual-rank modules per channel. The speed of an individual DIMM is not the only important factor anymore. For the 12th gen parts, Intel didn't even promise DDR5-4800 unless the motherboard only had one slot per channel.
