I know it’s been done for coffee lake a while back, and there was even some tool for it. But has anybody adding support for later CPU for a Ryzen board that has no official support? I imagine there’s barely enough difference with cjipsets that even if I found an otherwise identical board that does support the later CPU, I couldn’t just flash the BIOS and expect it to work.
Links to any example appreciated.
Looking to help some kid upgrade an HP Pavilion M01-F0 (3200G currently), 5600G would make a good upgrade if it’ll work.
AMD released an OEM firmware package for the early AM4 socket boards, IIRC it was X and B class, to support the 5th gen chips. IIRC, some people were able to monkey-patch the firmware, but it had a high risk of bricking the board, so unless you have USB flashback, the juice really isn’t worth the squeeze.
EDIT: wait, this is a B550. It doesn’t support the 5000 series?

I assumed it wasn’t because it had an older CPU. haven’t seen anything that specifies chipset. I don’t have the PC yet.
Typical garbage site that doesn’t focus on getting you to the info or even product you give a fuck about.

Link?
Looks like you’re missing a couple digits from the end of that model number. I’m starting to have trouble tracking down the exact model of this machine.

Yep, that’s it.
Thanks, might be the same link i tried to click that kept breaking before loading.

yeah, there site seems to mainly care about it ending with a or i presumably AMD or Intel.
Ohh, nice.
So it looks like your board probably only supports the following:
| Processor | TDP | Integrated graphics |
|---|---|---|
| AMD Ryzen 5 3400G, 3.7 GHz Base frequency, up to 4.2 GHz burst frequency, 4 MB cache, Quad core (Picasso) | 65 W | Radeon Vega 11 Graphics |
| AMD Ryzen 3 3200G, 3.6 GHz Base frequency, up to 4.0 GHz burst frequency, 4 MB cache, Quad core (Picasso) | 65 W | Radeon Vega 8 Graphics |
| AMD Athlon 300UGE, 3.6 GHz Base frequency, 4 MB cache, Dual core (Picasso) | 65 W | Radeon Vega 3 Graphics |
So basically, if you can find a 3400g for cheap, toss it in there, otherwise, you’re SOL.
Rabbit hole; I’m seeing this upon search:
Ok, so. The main problem with this is that if you look at the compatibility list, HP will say “compatible with these 3-5 CPUs from this specific generation of AMD” and they’re telling the truth. If it doesn’t say 3800x, the 3800x won’t work, even if the 3600x does. That’s OEM motherboards for ya.
I said 5600G for a reason, TDP. I also said “patch a BIOS” instead of just “update”.
I have had good luck dropping random CPUs in hp boards in the past. Far better than lenovo or dell.
Do you currently have the cpu, or are you planning to get it?
My recommendation if you have it already is to drop it in and see what happens. Worst case, no post.
Not yet, or I would just try.

Well, the whole firmware patching thing is a bit out of my wheelhouse. I wish I could help more, but at least we managed to find the compatibility matrix.

B550A is a refreshed 400 series chipset so depending on the microcode update HP has pushed it might support those CPUs or it might not. Check if there’s a BIOS update for your machine that’s after the launch date of 5000 series CPUs.
What I might suggest is trying to contact HP about it somehow and ask about the BIOS revision on the newest machine that supports 5000 series CPUs. If it matches the one you’re trying to update I think you might be alright to upgrade. If not you gotta gamble I guess.
Didn’t they vendor lock the cpu’s . So this cpu is mostlikly only going to work on that motherboard. So puting an ohter procesor on it would destroy it kinda. if you ever plan to upgrade.
I don’t see why other am4 procesors wont work. Aldo you should watch your powersuply if you have enough power.
You might be better of just getting an other motherboard before you put the procesor in, Then you don’t have to bother with all the HP crap. HP has been a shity company for some time now. 
they used to be really good. But you almost have to ask your grand parents
That’s “pro” series CPUs.
Last week I had to extract the VBIOS of an iGPU from the motherboard bios, maybe that will help you too
I have heard people claim that they dropped a Ryzen 7 3700x into these erica2 boardsand had it work without modification. If I can land one cheaply enough I may try it to verify. I already have a 400W power supply and a discrete graphics card in mine (GTX 1060 I scored for $35 on eBay).
