It seems that benchmarking can be sensitive to things that are not only related to overclocking.
I use hwmonitor, cpu-z, gpu-z to check stats, and hwmonitor will show me what happened while doing the bench.
This page is for me to remember what I archieved with different settings.
Day 1:
2dimms, 4GB ram, 21xx (9-10-9-24-1T),
Graphics core: 1047, memory: 2376, vcore 1.188v
Motherboard bios:
Vcore 1.58v
VSSIO 1.3v
CPU PLL 1.65v
To push it further, benchmarkwise
Disable all c-states
Disable turbo boost
Disable EIST, C1E etc.
Disable EPU
Disable TPU
ambient 24c
Boot
Test 1: 101,9 x 52 = P8610
Test 2: 101,9 x 52 = P8624
Reboot
Test 3: 100,0 x 53 = P8612
Test 4: 100,0 x 53 = P8595 (MSI AB maximized in background while benching)
Test 5: 100,0 x 53 = P8617
