Question Safe SOC voltage for Ryzen 5600g, 24/7 usage?

[Eperbab]

I'm playing with my G.Skill 3600 MHz CL18 memory, and I can push it to 4400+ MHz (maybe 4600?), but my benchmark scores are dropping, if it isn't running 1:1 with the IMC. Above 1900 MHz I need to increase SOC a lot, already 1.17 V @ 2066 MHz. So where should I stop?
I know, that the safe limit is 1.3V for the Ryzen 7000 series, but what is it for the 5600g?

Can you pass on a link to the ram kit? What is the make and model of the motherboard that you're working with? 1.2v is what's being stated as a number to be below for the SoC. Personally if you're chasing behind a synthetic number, you're wasting your resources going beyond DDR4-3600MHz on the AM4 platform.

In real world scenarios you're better off keeping the frequency as advertised but tighten the timings, since that's what Ryzen tends to excel in, tight timings high frequency, 2 sticks of ram(not 4).

BIOS version for your motherboard?

MB: ASROCK B550M-HDV
bios version: 3.0, I will update it to 3.30 later today
OS: Antix linux, Linux 6.1.42-antix.1-amd64-smp kernel
ram kit: G.SKILL 32GB Ripjaws V DDR4 3600MHz CL18 KIT F4-3600C18D-32GVK, https://www.gskill.com/product/165/184/1562833535/F4-3600C18D-32GVK

At the moment ram @ 4133 MT/s 1.40V / FCLK 2067 MHz SOC 1.17V passes passmark and system stability tester & 1080p gaming, but crashes with multithreaded y-cruncher.

I have tried tighter timings, but I need 1.40V for 3800 MT/s CL18, so not much room left, probably 3600 MT/s CL16 is doable?

I have managed to get stable 3800 MT/s CL17-21-21-21-40 @Dram 1.45V.
Unigine Valley 1080 medium full screen no AA results without curve optimizer or iGP tuning:
(resize bar on, 4 GB VRAM limit, uma_game_optimized iGP mode)
- 3600 MT/s CL18 @Dram 1.35V SOC 0.95V: 1794p, 42.9 fps
- 3800 MT/s CL19 @Dram 1.36V SOC 1.05V: 1804p, 43.1 fps
- 3800 MT/s CL18 @Dram 1.40V SOC 1.05V: 1814p, 43.4 fps
- 3800 MT/s CL17 @Dram 1.45V SOC 1.05V: 1834p, 43.8 fps
- 4000 MT/s CL20 @Dram 1.36V SOC 1.15V: 1848p, 44.2 fps

It seems, that the iGP likes higher bandwith more, than timing , but having lower SOC is also nice. The single core cpu performance seems to drop at SOC 1.15V, so I might stick to ~3800 MT/s. I will also try 3600 CL16.
And 4600 MT/s CL23 1.38V / CL22 1.43V just for fun.

P.S.
It seems, that I would need SOC 1.25V to pass y-cruncher at 4200 MT/s + FCLK 2100 MHz, wich is too high for 7/24 usage. Maybe 4066 MT/s + FCLK 2033 MHz is doable around SOC 1.18 V.

@Lutfij : thanks for the tip. I have a new personal single core geekbench record with
18-19-13-17-38-T1 3600 MT/s 1.35V. I will try CL16 1.45V later.
IIRC, tRAS should be CL + Trcdrd + command rate, or something similar.
