qb74 Which power supply are you using?
before z690 sold, I tried another 750w PSU, then my 500w PSU which currently works with z390d - nothing change
OS installed in feb.2024 with blocked updates, 2x sata SSD + GPU + 1x m2 SSD available only
moonpie which can kick in VRR more often
in my BIOS (2019y), OS (2020 may), drivers (mid of 2021) - there is no VRR
It would be joke if DDR5@4800 dont have such things. Last laptop I tested was huawei d16 2024 with 13900h and IRIS xe (same as in mini-PC) but caused me strain after 20 min. Laptop also used OC ram - DDR4X @ 4266mhz
