Question microcode for newer processors on motherboard BIOS?

[GunsMadeAmericaFree]

I just purchased an HP AM4 motherboard, new and never installed, for under 20 bucks. I figured that it was inexpensive because it needed an adapter to use it with a regular power supply.
I saw B350 chipset when I searched with the board specs, and figured I could use one of the 3 older AMD processors I had lying around to build a PC, install a Dell Perc controller, and get a couple of cheap SAS drives
I bought up and going to use as an occasional backup for several computers.

However, what I didn't notice was that the actual chipset of the motherboard was NOT the full b350 that I saw with a search. (that is what I get for trusting any AI results),
but was actually the B300 FCH.

it is an Elitedesk 705 G3 MT board. I was hoping I could get it to work with the 35 Watt 200GE processor I have.
Unfortunately, HP never released any microcode to support this cpu, evidently.

I have heard that programmers have sites where they share "copy and paste" code for various purposes.
Is there a corresponding website where motherboard BIOS hackers have shared microde to try in a BIOS,
to see if you might be able to get a certain processor working?

such places do exist. I would never try it due to how easy it is to brick a motherboard like that.

after some checking, I have come to the conclusion that this board isn't worth the effort.

read this thread, especially the last post to understand why.

HP 705 G3 MT CPU Upgrade to Ryzen

Hello, I have a HP 705 G3 MT originally shipped with a AMD A10-9700. I tried to upgrade the CPU to a Ryzen 7 Pro 1700X, what was one of the official purchase options from HP. The computer has been updated to BIOS version 2.37 without any issue, but the computer doesn't boot with the Ryzen...

I just found this on reddit, finally:

>There are TWO board revisions that shipped for EliteDesk 705 G3; early in the model marketing/sales period prior to Ryzen and later in the model marketing/sales period that >supported select Ryzen models. Given this was not a minor feature change, adding support for an entirely new line of processors, it SHOULD have received a new model designation >but it did not. It's not the norm but you do see it from time to time, especially from HP it seems.

>If your BIOS version begins with or contains "P09" (SSID or MB ID 835B), it will support select Ryzen models (with latest BIOS). If it begins with "P06" (SSID or MB ID 8265) your system >board is the earlier PCB that does NOT support any Ryzen models. HP documents have reported the following as compatible with "P09" BIOS board revision:

Hmm. So the latest revision of the board WILL support some Ryzen models. I may have to buy and try one of those old A6 or A8 processors just to see if I can get it to boot...

And now I just found this, on the actual HP website. Mine is the MT, so evidently it is actually the B350 chipset? Not sure if that makes any difference vs the B300.....
but a number of folks have 65 Watt processors working on the board.

Because it comes from a Micro Tower?

No, because it is way more complicated than it has to be.

It would be easier to just get a board + cpu from Marketplace or Ebay. Lots of people are upgrading now so it should be fairly easy to get something cheap.

Waste of money, calling Bristol Ridge garbage is an insult to garbage.

Here is the PDF that shows which APUs are compatible with the MT and SFF https://h30434.www3.hp.com/psg/attachments/psg/HardwareDPC/245426/1/705 G3 Quickspecs.pdf

I have used a retail boxed Athlon 3000g in an HP gaming PC with one of the Erica model boards despite it only listing official support for the the Pro model of the Athlon, so there's that.
