Safe SOC voltage for Ryzen 5600g when used continuously?
Safe SOC voltage for Ryzen 5600g when used continuously?
I understand your situation with the G.Skill 3600 MHz CL18 memory. You're seeing performance drops even though you're pushing it to higher frequencies, and your benchmark results aren't matching the IMC. Above 1900 MHz you're already adjusting SOC significantly, currently at 1.17 V at 2066 MHz. You're wondering where to stop without exceeding safe limits for the Ryzen 7000 series.
Can you share a link to the RAM kit? Also, could you tell me the make and model of the motherboard you're using? The specified voltage is 1.2v for the SoC. If you're aiming for a synthetic number, it might be better to stick with the advertised frequency and adjust timings instead of going beyond DDR4-3600MHz on the AM4 platform. In practical situations, it's usually better to maintain the advertised frequency and focus on tighter timings, as Ryzen performs well with high frequencies. Also, what is the BIOS version for your motherboard?
MB: ASROCK B550M-HDV model
bios version: 3.0, will adjust 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,

Right now the RAM at 4133 MT/s, 1.40V / FCLK 2067 MHz SOC 1.17V passes passmark and system stability tester, supports 1080p gaming, but experiences crashes when using multithreaded y-cruncher.
I've experimented with tighter timings, but require 1.40V for 3800 MT/s CL18, leaving little room, likely 3600 MT/s CL16 is feasible?
I achieved consistent stable performance at 3800 MT/s across various configurations. At different voltages and settings, the results remained reliable without needing curve optimizers or specific iGP tuning. The single-core CPU performance slightly decreased at higher SOC levels, so I opted for around 3800 MT/s. I also experimented with 3600 CL16 and 4600 MT/s at 1.38V/22V for testing.

P.S.
To pass y-cruncher at 4200 MT/s with 2100 MHz clock speed would require SOC 1.25V, which is challenging for daily use. A possible adjustment could be 4066 MT/s + 2033 MHz.
Thank you for the suggestion. I've achieved a fresh personal single-core Geekbench score of 18-19-13-17-38 at 3600 MT/s and 1.35V. I plan to test CL16 at 1.45V next. According to what I know, tRAS should be CL plus Trcdrd plus command rate, roughly similar.
