Yep, X299e-itx/ac.
Nice thing is, you then get quad channel, which for some workloads is a huge performance boost.

Now in that use case, I'd agree. If we could get four 16 GB SODIMMs in a SFF PC it would be really cool.
Well considering I (the person who started this movement/post) only needs the non APU support specifically for my sleeper PC build, ITX doesnt fit in a gamecube, there are also use cases for headless encoding servers that only draw ~100W and are in a tiny case. So its kind of important, to me at least.
Well no, its just not your use case. I don't totally see the the draw of unlocking the cpus on the A300, while the APUs do overclock decently I doubt they would sustain significant gains on this board as they apparently cant sustain stock boost clock for long on the board anyway.
Honestly almost everything that everyone on this site wants is a niche within a niche, this just happens to be one layer deeper.
With granular control over CPU and GPU voltage we might be able to get a bit more out of the APU, but I agree that it's barely worth the trouble. I'd like to see the features added in large part because I don't like having gimped products.
Hi guys, I just discovered this thread, was searching for any info on 3700x support for a300 as its a 65w CPU. Just wanted to let you know that I am using A300/3400G with RADEON 7 via external PCIe slot connected to an M.2 slot on the motherboard. It's working like a charm, both in Win 10 and Debian, kernel 4.19 and 5.2 tested. Games are running on ULTRA settings on a 4k monitor, both in win and Linux. It took a day or two dealing with mesa and GPU drivers in Linux but I managed to make it all work. As for Windows, not a single issue so far. And I am using this build for over two months now.
As of right now there is no support for any Ryzen CPUs only the APUs (2200/3200g and 2400/3400g). The issue seems to a problem with POST, essentially when you put a a non APU part in the A300 the fans spin up but the power light does not turn on, we think that the issue is that ths POST process is checking for the igpu and not seeing it (because its not there) and hanging at that point. This may be able to be fixed by either removing that part of the test or just fixing its value to pass/true.
I started this thread with the original goal of only fixing the CPU support, and it seemed promising for awhile but our resident BIOS modder hasn't updated us in awhile (as I understand it they're a college student so things get busy and this a hobby).
I'm trying to get back in touch with Asrock because the answer I was given back in March/July was essentially that it could work but they where to busy to work on it (ie Zen2/x570). With the potential of new threadripper boards looming on the horizon I don't know if their answer will change but Im still going to ask.
Ive been meaning to look into learning how to mod the BIOS myself but havent got around to it as I'm a student too, but I will look into it and potentially see if there is anyone in my schools computer engineering department that may be able to help.
Thanks for the reply W4RR10R,
We had a similar issue in Debian, the external GPU would not work because the system didn't expect to see an external PCIe slot and another vega on it so he didn't know what to do with it. You might be correct when you say that the issue is likely POST related, the hardware is all there to support 3700x, its the software that doesn't know that it can.

You might not though, the 3700x is a 65w TDP chip. While TDP is not real world power draw its usually a pretty good estimate. Likely if you are using a 3700x you would also have a beefier power setup to also power the gpu. If you went with a headless setup for like a mini home server depending on your workloads I dont see the the system exceeding the 120w ac adapter, barring having 2 m.2 drives 2 hdds and alot of usb devices without external power.
A 3700X with PBO enabled can use between 110 and 115 watts. That's running pretty close to max on the stock power brick. I guess if you kept PBO disabled then you could limit CPU power draw under load to 90ish watts.
Hello everyone,
By chance just happen to see this thread a few days ago.My AS Rock 300 is on the way , I've just order it together with the Ryzen 5 3400G. As I'm looking for a solution to this topic too , specially regarding CPU+IGPU overclocking and it seems you were not able to come up with a viable BIOS I want to share a video review in which it seems that AS Rock themselves had released initially a BIOS that support these features.Maybe this information will provide itself useful.
Have look on this video review:
There clearly can be seen that the OC functions for CPU+IGPU are available.
Maybe we can ask the guy which BIOS version did he used.Hopefully it was not an engineering sample or some sort of.
Best Regards

Hello
Early bios versions did indeed have options, but they did not work. I believe Asrock did not intentionally put those options there, rather they forgot to remove them (as they were not functional). Later asrock removed the options from the Bios...
Hey so Ive just started working on my GameCube PC again, when I setup my e/dgpu it doesn't get detected and I cant remember how I did it the last time. If you wouldnt mind running through how you got it working. Im running a vega 56 btw.
The card does work I can install it another system and it works just fine.
Nvm, I think one of my m.2 adapters is broken. Swapped it and it just worked
My apologies for the late reply guys, very busy schedule. Yes, the card we were using for testing was Radeon VII (cos it looks nice and fits perfectly into our design), the riser was manufactured by this company... https://www.adt.link/
However, we have switched now to Thunderbolt 3 riser (our own design) since ASRock has T3 mini ITX motherboards for both AMD and INTELL chipsets now.
X570 Phantom Gaming-ITX/TB3
Z390 Phantom Gaming-ITX/ac
Those 2 motherboards are only 2cm larger in size then A300W and it's much more convenient to use T3 instead of M.2 slot.
In the case of MINI- STX build ( external GPU connected via M.2) GPU is powered via small 650 W DAGGER PSU, for the MINI ITX build (external GPU connected via bothT3), we are using a custom made 650W PSU that supplies power to both, PC and External GPU enclosure.
