ASROCK X370/B350 ryzen 5000 series mod

[R-T-B]

Thanks for that pointer.

Damn, I tried to check the chinese junk marketplaces, and of course, all the flashers they offer have black PCB. (There are green ones but without the cable/clamps for flashing chips that are soldered on board.) FML

Usually what I do is grab a soic 8 clamp and some wire jumpers and build my own. There are solderless ways of doing it.

Hi guys, i have and AB350m Pro4, and a CH341a+1.8v adapter+soic8 clip, i have that flasher because I bought it for my mobo when died when i was updating it and then power cut. I was reading all your experiments and i was thinking with the tools i have can i update my ab350 pro4 to get ryzen 5000 support. By the way i am kinda newbie.

i did not get a notice until today about this. yes you can. just follow the steps listed. update to bios 2.40 from the b450m pro4-f. all the newer ones do not work. hopefully you figured this out already.

Hi, I'm sorry if this has already been asked (and I don't really mean to revive a dead thread). I have an Asrock AB350 Pro4 motherboard (the regular one, not the M) https://www.asrock.com/mb/AMD/AB350 Pro4/index.asp#Overview I was just wondering if you knew what bios I should flash to it for Zen 3 functionality. I was thinking the B450 Pro4 bios (the 4.5 version), but I'm not sure and don't want to do something wrong. I think that I read a reddit post saying that the AB350 Gaming K4 beta bios worked with this board as well. I've never updated my bios before (at least I'm like 90% sure that I haven't). Do I need to do any other updates before flashing the new bios, or can I go straight to the new one? Is the process as simple as just opening the bios file in AFUWINGUIx64 and pressing Flash, or is there anything else I need to do? Are there any downsides to doing this, or will everything function as normal? I don't even have a 5600X yet, but I was thinking of getting one, and if I could stick with this motherboard that's probably the upgrade direction I'll go in. Thank you.

use bios version 4.50 for the asrock b450 pro4. you can directly flash to it using afuwinguix64. unzip the bios and move it to your desktop then open the bios into the program and set everything as follows:

then press flash. if the flash fails than DO NOT RESTART. grab a copy of the bios for your board that works with your current proc then flash it using the settings shown above.

good luck.

Hi,
Afuwingui seems to just freeze after the read phase whenever I try to flash that bios (it never even starts to erase). I was able to flash a bios that is actually for my motherboard though (so I didn't end up bricking my board). I guess I'll have to look into it more. I'm not sure why it's not working. Also some ROM HOLE boxes get checked whenever I pick the B450 bios. I'm assuming those stay on because of the Program All Blocks option. Thank you for your help though. I appreciate it.

HERE is a thread i created way back on cross flashing the motherboard im using now

I gotta give you a big hand with your experiments! Hat off!

In your original post you said that with B450M Pro4 BIOS the CPU fan control did not work properly on AB350M Pro4. Does fan control work with B450M Pro4-F BIOS?
Is there a reason why I should buy the separate BIOS USB flasher thingy, or can I just do the update with AFUWINGUI as you did in original post? I do have "old enough" BIOS in that board (less than 5.50).
Thanks!

 

[Final_Fighter]

You have to use the the -F bios. The fan setup from the non f will just run at 100%. Also, don't update past 2.40. if you do it's likely your board will not boot and you'll need to get the flasher to make a recovery. One last thing, the board can take a minute to boot after a bios update so give it some time after flashing.

I cross-flashed B450M pro4-f 2.40 BIOS onto AB350M pro4, as a result, a ryzen 1700 works completely fine, but when it comes to 3700x, it only boots with DDR4_A1 or DDR4_A2 slots, if B1 or B2 is occupied, it won't boot.

haven't tried other CPUs/APUs yet...

 

[seth1911]

I have a B350 Board from Asus it can use APU from the A10 9700 to 5600G, nah just a online friend made a bios mod for them.

There isnt any reason to limitate B450, B550 down to Bristol Ridge or B350 up to cezanne,
many fanboys say its because the 16MB Bios chip, no it isnt its cause amd would sell new products, not sitting back on old chipset and support them.



Amd told on Am4 release all would be supportet on AM4 and now the same shit like intel with 1151 v2, same socket only no Chipset support

I can confirm that a Ryzen 3600 also has the same symptom as 3700x:

Also, it doesn't boot only if a JEDEC(non-XMP profile) DDR4-2400 RAM is present:

CPU	A1	B1	Boot
3xxx	2133	-	Yes
	2400	-	Yes
	-	2133	Yes
	-	2400	No
	2133	2133	Yes
	2133	2400	No
	2400	2133	No
	2400	2400	No
1xxx	any	any	Yes

Looks like there is some DIMM compatibility difference between these 2 motherboards (AB350M pro4 / B450M pro4-F).

Hi, can your friend help mod bios for other boards, specifically, I'd like someone who can make a bios for gigabyte AB350M-HD3, it's the only board with slim M-ATX factor (24.4 * <22.0) and 6 sata ports. It would be a very nice option for a NAS, when used with an APU like 4350G. Yes I know 3400G works natively but just want something better.

 

[yumeyao]

following report: 5600G(retail version, not the early OEM version) doesn't work on cross-flashed AB350M PRO4, despite that B450M Pro4-F 2.40 BIOS claims 5000G is supported.

Hy i will ask em in about 2 weeks

I have the ab350m pro4 with bios 3.30. So, I can directly upgrade to bios 2.40 from the other b450m pro4-f board, right?

Correct!

In my case however, I updated my BIOS past 5.50, so I have to use the ch341a programmer which I purchased.
Unfortunately, I was not succesful upgrading my BIOS with the update tool. Either my programmer is broken, or the tool didn't work: although the tool was pretending to do something, the BIOS version didn't change at all!
Had anyone success and can give some advice or assistance?

 

[Bomby569]

you may hold on it as AMD (see the latest news) is considering doing it

 

[joshua_vlad]

Correct!

there are several app for the programmer, i remember using it for recovering a dead mobo, and the app recommended for the programmer was giving me errors, so i tried several app, the one that i used was neoprogammer, try several apps and if you still having issues then the problem is the programmer

 

[jedi23]

I will give neoprogrammer a try next time...

But hopefully it won't be necessary if this is really happening:

AMD Explores Adding Ryzen 5000-series Support to 300-series Chipsets

One of the most debated questions surrounding AMD's AM4 platform has been the lack of support for AMD's Ryzen 5000-series CPUs on the company's 300-series chipsets. Now, in an interview with Tom's Hardware, AMD's Corporate VP and GM of the Client Channel business, David McAfee, has thrown some...

[jedi23]

It is really happening:
Official Zen 3 supporting BIOS updates now available for X370 Pro4, A320M-ITX and A320M-DVS R4.0!

Let's hope the B350 boards will follow soon!

 

[joshua_vlad]

guys, i recovered a dead b450m pro4 mobo that died being updated and power cut happened, i recovered the mobo using CH341a+1.8v adapter+soic8 clip, backed up the corrupted bios and erased the bios and then flashed the latest update from asrock site to my mobo, everything is ok apparently, but i lost ethernet port usage, i connect a cable, and doesnt detect it, even the orange/green led light isnt turning on, maybe something is corrupted with the ethernet port on bios chip i dont know, i am just guessing, do you think i am able to get back the ethernet port?

 

[jedi23]

No I don't think so. Use a USB to Ethernet adapter instead.

Asrock has new beta Bioses for X370 Fatal1ty and Killer boards with Zen 3 support released.
No B350 yet, but let's hope they're on it!

Yep, it would of course be nice to have official support.

 

[joseLopez]

At the moment it seems that they are reluctant to release a new bios for the ab350m pro4.
