Update on my timings for 3600 @ 1.44v, these are Memtest stable, 51800 Read, 28787 Write, 50400 Copy, 66.9ns Latency. SOC and CLDO VDDG are both set to 1.1v CLDO VDDP is on Auto.
I have changed the table that I was working from, it now includes the Auto settings from my motherboard (CH7 Bios 2501 AGESA 1002) as well as the figures from Ryzen Calculator for Profile versions 1 & 2 Safe and Fast, which hopefully will be useful as it's possible the Version 1 timings might be stable on AGESA 1003 and later but I'm waiting for Asus to update the BIOS for my board.
