Played some pi early on to help sort memory profiles for the Aqua OC Butthurt edition.
4900 14-14 with loose seconds and thirds all ambient cooled on both cpu and memory.
Also 4800 14-14 with super tight seconds and thirds is only slightly slower. Unfortunately 14-13 fails all the time on ambient so it's more than likely just this IMC.
Will try a few other cpu's and see if any can run 14-13 on ambient. One thing I've noticed after seeing some screens is Asus runs tighter RTL but looser IOL, maybe one is better than other but idk haven't had a chance to test this thoroughly.
