I`m up and running. All smooth. After 8h testing/rendering, not a single blue screen / crash.
Booted right away, updated bios, no issues.
All 8 G.Skill sticks work fine on factory XMP profile, 128GB at 2933. kit is F4-2933C14Q2-128GTZRX , timing 14-14-14-34 .
Performance wise, tested multiple PBO configs from 250 to 500, and i settled on 400/400/400 for now. With that i get good single core performance boosts to 4.1-4.2Ghz, and for multicore I get 5750 in cinebench. Aorus VRM at this settings, after 1h rendering never peaked above 100C.(with extra fan on the backplate of the mobo)
Asus Hyper m.2 x16 works perfect on x399 too, With 2x2TB Samsung EVO 970, i get 6800MB/s read, and 5000MB/s write. Raid needs to be setup in BIOS, 16 PCI slot set to 4/4/4/4 and AMD raid driver installed at windows installation.
V-ray bench - 24 seconds
Corona Bench - 36 seconds
Only issue with EKWB vardar fans, from 9 of them, 2 suck, one ignores PWM(maybe broken cable), and other one is noisy af. But damm, that orange/red heat looks good on them :) will return and replace.
