More quiet and much better thermals:
-Underclock: Set Pstate0 MHz manual to a lower max. clock speed. E.g. 3300 MHz
-Disable Core Performance Boost! This is generating insane heat.
- Save and reboot into bios and now:
-Undervolting CPU in BIOS to 1.1V or even 1.05V maximum.
Installed BIOS 3.60S (Agesa V2) today.
I'm using A300 and Ryzen 3400G.
Game performance is better and finally the HDMI port is stable (no black screen from time to time).
I disabled Core Performance Boost for better thermals, but BIOS doesn't offer CPU voltage settings.
I'll stay with this BIOS...
Is 3.60N Bios safe if Ryzen 3400G installed?
AMD X300 and A300 (non-)chipset are identical, only difference is UEFI Bios overclocking capability. Nice update for new Deskmini users.
Ryzen 4000 series will work on both platform. Asrock has great Bios support, i believe they will release a stable A300 Bios for Renoir APUs.
Edit: Does anybody...
Need to underclock/undervolt my Ryzen 3400G to get better thermals.
My BIOS ist 3.51 3.60
Already disabled Core Performance Boost.
Don't know what to enter in BIOS to max CPU and GPU frequency at 3400MHz.
Got my A300 & 3400G running with these:
1x Kit: G.Skill SO-DDR4 32GB PC3000 CL16 (2x16GB)
or if cheaper:
2x G.Skill SO-DDR4 16GB PC3000 CL16 (1x16GB)
These are near the price/performance sweetspot imho.
Works fine in a passively cooled Case at high temps.
32GB is more future proof...
USB-Cable: No, bought this rebranded as Delock USB cable. The header pin connector is smaller in size, Asrock USB Kit has bigger header block size. Pin layout is the same, but don't fit.
Audio-Cable: Audio internal header plug is square. -> Won't fit.
