I see, A300 supports even higher clocked RAM (3400+)To add, they are on the Asrock Memory QVL for Picasso and for me the 32GB kit CT2K16G4DFD832A (3200 MHz 22-22-22-22 nominal) runs 3333 16-19-13-16 @ 1.35 Volt. 3400MHz is still stable but have to loosen tCL to 18. Picasso might even perform better with the kit.

You could use 2 of the modules from the 4 module kits, but the limit would be the memory controller (IMC) in the CPU. Zen / Zen+ (2000 Series APU / 3000 Series APU) will top out earlier. My understanding is somewhere around 3466 MHz is the typical stable limit the the IMC for those processor cores, that would be no different on the Deskmini. So little gain from the kits rated 3800+. This may change if Zen 2 based APUs were to become available (Renoir), the Zen 2 IMC can drive much higher clockspeed.I see, A300 supports even higher clocked RAM (3400+)
So i could use even two of these?:
- G.Skill RipJaws SO-DIMM Kit 32GB, DDR4-3800, CL18-18-18-38 (F4-3800C18Q-32GRS)
- Corsair Vengeance SO-DIMM Kit 32GB, DDR4-4000, CL19-23-23-45 (CMSX32GX4M4X4000C19)
Is it true RAM is still faster when the memory clock speed is higher even when Latency-values are worse (e.g. CL19-23-23-45)?
e.g. see nanoseconds values: CL16 (3000) is slower than CL19 (4000MHz)

I'm sure a LOT of our issues can be resolved with a BIOS update but I don't think ASRock is making it a priority. I've tried to reach out a few times and they believe everything is fine. Most people who purchase the A300 aren't trying to squeeze every last drop of performance out of itI do think a shroud would help. With the Wraith it's not needed because it sits so close to the vent. Heat/overvoltage issues should be resolved if they ever release the 18.104.22.168 bios
If the sight of it doesn't bother you, you could just have a barrel plug coming out of the back of the case, plugging into the power entry plug, from your internal PSU. Otherwise desoldering is what you'll need to do, it is possible though I'm not sure anyone here as reported doing it.Is it possible to de-solder the power entry plug from the board or how should I do it if I wanted to go brickless with the A300 motherboard?
The 3.51 BIOS? I don't think that is a Combo-AM22.214.171.124 BIOS but a Combo-AM4 126.96.36.199 BIOS, like 3.50. It only introduces some fix for issues with Hyper-V under 3.50 from what I read and people have gotten it from ASROCK support directly if faced with those issues. Haven't tried it though.
No but actually you were right. I just updated to it, BIOS L3.51 is AGESA Combo-AM4 188.8.131.52, not 184.108.40.206 as I had wrongly assumed before. This can be confirmed from the AMD firmware version submenu somewhere in the AMD CBS menu in UEFI. It does contain an updated ABL and an updated processor ucode patch, compared to P3.50. SMU firmware appears to be the same as P3.50. It performed at best the same for me as P3.50, which in turn performs worse than P1.20 for my 2000 Series APUs. YMMV for a 3000 series APU. Personally, I have reverted to P1.20.Oh dang you are right it's 220.127.116.11abb not abba
I have an Intel STX board (started with Asrock but now on Asus H110S1/CSM) , but regarding the similar Noctua L9 fan , I recomend keeping a constant rpm up to some threshold. At constant 800 rpm, it is almost inaudible, even up to constant 1000 rpm, its is very silent. Higher oder varying rpms OTOH, are audible.
