Ok so there a bummer now...
ASUS released a new vbios update for my laptop model and looks they locked the max OC to +300 on memory. Not sure if that's a bug or was intentional.
My hashrate is stuck at 56MH/S @107W now.
Bro, affecting me too. After your post, i just find out we could use winflash to roll back, i yet to try but most of the asus laptop users feedback are working, i will try it after

After i tried few aproaches but not success to OC + 300above, below the steps I have tried, perhaps someone can try other methods and do not need to repeat:
1. Rollou back the Bios from version from 319 to 315 (Need to go System firmware to disable system bios will restart PC will System will auto goto UEFI to request Bios update), OC memory still only +300.
2. Reunistall the Nvidia display software version to older, OC memory still only +300
But will okay with stick at 55mhs rather than half cut of it
