BIOS: F10
RAM: Kingston Fury DDR5 2x16GB 7200C38 Hynix 16Gb A-die
RAM/SOC voltages
VSOC: 1.2V // High VSOC usually limits max FCLK
VDDIO_MEM: 1.3V
DDR_VDD: 1.43V  // make sure your RAM has good cooling
DDR_VDDQ: 1.3V
VDDG_CCD: 1050mV // raising this can help stabilizing high FLCK
VDDG_IOD: 950mV

RAM/SOC clocks
MCLK: 3000MHz = DDR5-6000
UCLK: 3000MHz (UCLK = MCLK)
FCLK: 2200MHz

tRAS: 30

Secondary Timings -----------------------------------------------
tRC: 58
tWR: 48
tREF: 65535
tRFC1: 466 // can go lower
tRTP: 12
tRRD_L: 8 // can go lower on some kits
tRRD_S: 4
tFAW: 20

Stress tests passed:
2000% HCI memtest
Testmem5 4x Extreme1 Anta777
100x Linpack Xtreme 10GB

notes:
this was mostly a test of A-dies ability to do low tRP. Thank you to Gigabyte for providing the motherboard
