I thought I'd start a overclocking thread for Zen 2. I know there isn't much to gain from manual overclocking these CPUs, but at least memory overclocking is more of a thing now.
I got my 3600 on Tuesday, so haven't had a lot of time to play with it yet. It's paired with the popular G.Skill F4-3200C14D-16GTZR B-die set on a Asus X370-I (dual-slot DIMM).
The SAFE timings suggested by 1usmus's DRAM calculator v1.6 is not stable for me above 3200MHz, but I wouldn't expect 14-14-15-14 to be a given for 3600MHz and up on any B-die kit?
What I have tested as stable with Memtest is 3733MHz (1:1 fclk) at 1.45V, SOC 1.1V. Manual timings of 16-16-16-34-48, Trfc 298, Trdrd/Twrwr SCL both 4, and most of the rest Auto.
I only have PBO enabled, not auto-OC, and a negative core voltage offset of 0.0125V, which seems to help lower temps a little bit without losing performance.
