With x4 this issue is gone 4835Mhz c15
It's A2 pcb. 4600 with these and tight subs is not booting. It's @1.8v tried up to 1.9v and close to 1.4 VCCIO/SA and it cannot go higher...but non the less it's impressive comparing it to regular 370/90 boards.
Edit: This was the highest frequency with lose cl16 4750... 4800 can boot but not entering Windows even freezing in Bios.
Let's hope the new upcoming Bios will get some more Oc to them
