Enriched MSI Z690 Unify X PCB Breakdown notes (Patreon)

8 layer PCB. Having more PCB layers CAN help reduce the impedance of power planes. Which can lead to lower VRM+PCB operating temperatures and better voltage regulation.Extra PCB layers can also help with RAM overclocking.-------------------------------------------------------------------------------------------------------Vcore VRMCONTROLLERRAA229131 20 phase controller running 19+0// use 500KHz VRM switching frequency for best voltage regulation performance. Higher frequencies have steadily more and more buggy behaviour.
