AsRock X399 Phantom Gaming 6

ASRock X399 Phantom Gaming 6 motherboard (ATX), scanned on our rig. MOST IMPORTANT: THE DIMM SLOTS MUST WORK. All 8 DDR4 DIMM slots are real open sockets that a DDR4 UDIMM inserts into straight down, key aligned, fully seated, with both latches closing. Each slot channel must be wide and deep enough to take the module's edge (below), with the DDR4 key ridge at the position matching the module's key notch, and a latch at each end that rotates open and closed (revolute joint). The collision geometry must keep every slot channel OPEN (no solid box over a slot) so a module can be inserted in simulation. THE SPECS ARE GROUND TRUTH. Where the reference mesh, photos, video or any measurement disagree with the manufacturer documents below, follow the documents. The scan, photos and video are for appearance, overall shape and anything the documents do not cover.
