Yes, but be warned, as you want to use it in a server like fashion, ASRock as left it on AEGSA 1.0.0.1 and its associated modules which have known issues with virtualization

in addition, sometimes with m.2 drives, it just stops seeing them as a bootable location and wont boot

any owner of the A300 should open a ticket to get them to fix the boot issue and update the AGESA and associated modules otherwise it wont work properly with Zen+ APU's (not to mention the other fix's/improvements that impact Zen/Zen+ are lost)

If it's 3.5 then you are good to go with the 3400

Bios version is P3.50 from what i see its supports AMD Ryzen 5 3400G Boxed.

I checked the 2400g but only see higher prices of that product.

I would double check the BIOS version on your A300 and make sure it supports the
R5 3400g:

Personally, I would go with a 2400g and save a bit of money. The 3400g is only
a fraction faster, nothing you would notice unless you are going to be running
heavy compute tasks for prolonged periods. It will also be sure to work as it
is supported on all BIOS versions since release.

The BIOS version will be printed on a small white sticker on one of the chips on
the motherboard. You will need 3.5 for the 3400g.

Thanks for the fast repsonse. I guess i just have to buy the APU than.

So when i buy the APU it will work right? The RAM memory and disk storage are compatible right?

I highly doubt it and yes, that is an APU. The display output on AM4 boards is to
facilitate CPUs that have built in graphical capabilities (an iGPU). Back in the
old days when boards had a GPU output there was a GPU built into the board, either
integrated into the chipset or on a separate chip but today, they are either built
into the CPU or require a dedicated GPU.

There are some boards that allow for "headless" operation (no monitor) but even
these require a GPU, be it an iGPU or a dedicated card. During the POST
(Power On Self Test) the system looks for a GPU, if it does not find one the process
halts and the system will not boot.

Owww terrible.So APU is a CPU with GPU or something?

I'm going to use it as a server is it possible to install software vcenter on it and not using a APU?

And to be clear this is the APU you are talking about right?

That CPU isn't compatible with the Deskmini A300, at least not without an M.2 to
PCIe converter and a discrete GPU.

You need an APU with the DeskMini, the 3600 does not have an iGPU. So, the R3 2200g
R3 3200g, R5 2400g, R5 3400g, Athlon 200ge, Athlon 3000g.
