CPU [24/03/2025]ASRock DeskMini X600 BIOS "4.06" & "4.08" & "4.10" - with new AMD AGESA ComboAM5Pi v."1.2.0.2a" & DDR5 SO-DIMM Voltage Settings available

[game9370]

hello everyone! thanks to a comment from HydrAxx747 that I came across on reddit I went down the rabbit hole of running a more powerful cpu on a deskmini board. the current idea is running a 9800x3d with some UV mainly for gaming and, when not home (so without an egpu attached via oculink), use the mini pc for media consumption and documents consultation.
I'm still tangled up in the 9800x3d shortage but that should get solved in the upcoming days, so now I'm left with some first setup questions. which is the newest bios version that is worth update to? I haven't turned my machine on yet but I suppose I can't be on anything past the 4.03.
regarding ram, I've acquired a 2x16 6400 kingston fury kit, I suppose speed and timing wise it goes the same as with normal dimm ram, so 6000mhz with tightest timings, correct? has anyone recommendations for an ideal starting point? i guess 6000@cl32 could work, but I haven't got a clue about secondary timings.
for anyone that has been running this board with a non-listed cpu for awhile, do I have to worry about early wear of components? I was thinking of stressing the board without extensive mods in order to highlight any issue (too extreme temps for mosfet's, ram or ssd perhaps) and see what I can improve on. I'd like to keep the stock case but if deep cooling mods are needed then I'll build one myself.

quick recap of components:
deskmini x600
9800x3d
2x16 6400Mhz Kingston Fury
4tb 990pro in the slot on the underside
m.2 to oculink adapter over the wifi card
ax210 wifi/bt card

If you are not using an IGPU i would not bother to much with tightening timings....If you see videos in youtube the minimal gains are not worth the trouble.The IGPU that this processor has its only for basic things or very old games,should be just 2cus if im not mistaken.There is also a chance that you will need a bigger power brick than the 120 one to run it as intended.If you still want to give a try with timing tho,you can simple see the previews pages and you will get a clue as to what you need to do.As for the bios you simply go to asrock x600 deskmini page and get the latest one available,you most likely need it in order to use the 9800x3D.As for cooling,even the best low profile one (that fits) Thermalright AXP90-X47 Full wont be easy to cool this one inside this small case...

Thanks for the answer. Updated the bios to 4.03, the 4.08 is said to have removed to option to use a more powerful psu. I'm using a SlimQ 240w psu and the thermalright x47 FC. Everything works fine, other then this issue that I haven't explored on the forum further so excuse me if it has already been discussed and/or solved. The issue I came across is related to PPT. I update the bios, installed Win10 on the ssd and booted into windows. Tried running a simple CinebenchR23 benchmark with HWInfo running and the total cpu power draw was stuck at 87/88W, with temps not even reaching 70° with a very gentle fan speed. Tried going into the bios and playing around with the PBO settings in the advanced overclocking menu and setting the limits to either "motherboard" or "manual" did nothing, whatever the PPT was once in windows Ryzen Master always showed an 88w limit. Out of curiosity I then set the preset PBO in the OC Tweaker menu and problem solved, now the PPT is set at 1000W and the CPU is able to keep a sustained draw of over 100w (starts at 120+ then the 85C limit kicks and the power draw stays between 105 and 115w).
With the 85C and -20 preset I managed to achieve 21638pts in multicore, so around a 1000pts deficit versus what I saw online.
Instead, with the 85C and -30 preset I managed to achieve 22086pts.
As of now, I'm going to be using the system without the case (the x47 actually slightly hits the case and also obstructs the serial port where i would've made the oculink cable go through), when I have some spare time I'll fab one up that houses a couple of 40x10 fans to help reduce heat inside the case.

What i did with mine is to remove the back aluminum in order for the hot air to escape easier,cant test it yet tho cause my CPU is still not here.....I assume it will make a difference but how much not sure yet. Personally i find 85c too hot i would not want my cpu to run hotter than 75 at worst.Thankfully you can do that from the bios.I would advice not to touch timings cause it will produce even more heat inside the case with minimal returns...Just use the faster profile and you will be fine.Do you have an external GPU?

If you want to modify the original case and money is not a concern, have a look at what I did with the NH-L12Sx77 here https://smallformfactor.net/forum/threads/asrock’s-x600-deskmini-–-finally-–-again.19619/page-6#post-289110

That solution cools both the CPU and the memory with a single fan, and it fits in the original dimensions except for the height

Yes I do. As of now I'm still running my old trusty 1070, in the market for a 4080 when they get slightly better price for the usual new release buyout race. I'm using an EXP oculink adapter (the latest one with the redriver, probably supports hot plugging but haven't tried it yet), works like a charm, boot times are insanely fast even without thinkering with the andrenaline drivers I installed for the igpu of the 9800x3d, no error 43 or whatever, hopefully the story doesn't change when I get a newer card.
About the timings, I'll do some research to see how they affects gaming perf on this cpu, that's the only scenario where it interests me, all my other work is "heavy" 3d stuff that isn't quite affected by ram timings.
Regarding the temperature, 83/85 is usually what people limite their ryzen at. I'm coming from a 6600k with a 120mm aio in a full tower with 3 fans and gosh is it louder, even with the calmest fan profile. Even during a 10 min cinebench run the thing wasn't louder then my ac with the fan @2700rpm, that's what they talk about when people say You need to feel it for yourself lol.

Thanks for the heads-up. I did explore the idea of using a bigger fan, I bought a 140mm slim fan and although it was definitely quieter (even more then the already dead quiet thermalright one) the results were no where near as good, perhaps I could've got better temps on the ram and vrm side of things. As of now my plan is to get the x53 instead and use a couple of 40x10 fans to create some kind of airflow in a custom case which shouldn't be much bigger, just better layed out. I'm still figuring out stuff tho, I had to place the ssd on the back because the oculink adapter that I got with the kit was hitting the intel part of the back plate of the cooler (could very well cut that off if needed), but I don't like the idea of having to open the case up every time I need to unplug the e-gpu.

Here is the video to check how much timings matter,it also has your CPU.

Basically he has shown that x3D chips don't care about ram, nice to know I guess! Thanks again for the help.

Is it confirmed that BIOS 4.08 will not allow (does not recognize increased PPT, TDC, EDC) power over 88W? Thanks.

I read that somewhere and honestly I'm not willing to experiment lol
it would definitely suck if this was the latest bios we could upgrade to because of this limitation.

 

[Gamma89]

Good morning,
I installed bios 4.08 and the CPU tests work well with excellent scores.
The problem starts when I try to game and then I use gpu+cpu a lot (8700g 780m) the GPU and RAM clock continuously drops with frequent intervals to 800mhz GPU and 1000mhz RAM.
It appears to be a power limitation but any BIOS setting has no improving effect...
I use a 180w power supply.
Temperatures are not a problem.
Do you have any ideas?

 

[carpler]

Any news about a BIOS update?
After @HydrAxx747 mentioned it in December, reporting that he had let his contact at Asrock know about the performance degradation due to the removal of 'Performance Mode', there has been no more news...
Can we expect an update soon?

Install AMD Ryzen Master and check PBO settings in Advanced View, specially power limit (PTT) and current limits (TDC, EDC both CPU and SoC)
I have PTT limit to 65W and current limits pretty much maxed out (CPU TDC = 180A, CPU EDC = 250A, SoC TDC = 30A, SoC EDC = 45A)

There are also other power settings for boosting behaviour named slow PTT and fast PPT, but those are not present in Ryzen Master. You should also check those just in case. You can use a utility like ryzenadj (https://github.com/FlyGoat/RyzenAdj/releases) to set those limits, I.e. to set all PTT values to 65W use the following commands (input values are in mW):

ryzenadj.exe -a 65000
ryzenadj.exe -b 65000
ryzenadj.exe -c 65000

I tested 4.08 for a while and I didn't experience any performance degradation, but I guess that's because I set PBO settings manually to what I want. As far as I know, the "Performance Mode" on older BIOS was just raising some of the PBO current limits.

The x600 motherboard has 4 phases of 5 amps for the CPU so the theoretical EDC cannot exceed 200 amps. The SOC has a 50 amp phase to power the GPU apu. With the 4.08 bios I can't go beyond 120 amps EDC while with the 4.03 bios I get to 150 amps ( see HWinfo ). I think this is the reason for the power drop. With bios 4.03 everything is at maximum I touch the 170w from the wall so it's its limit. The total power of my 8700G reaches a maximum of 125 watts so the rest of the energy is dissipated by the motherboard and the other peripherals.

The total power of my 8700G reaches a maximum of 125 watts so the rest of the energy is dissipated by the motherboard and the other peripherals.

One thing I'd like to note is that apparently the iGPU power delivery of the 8700G is derived from the same rail as the CPU is, as stated by skatterbencher in this article: https://skatterbencher.com/2024/02/09/skatterbencher-70-amd-radeon-780m-overclocked-to-3150-mhz/

VDDCR_GFX provides the voltage for the integrated graphics. In the past, this voltage would be provided by the VDDCR_SOC voltage rail. Still, it’s likely due to the high current requirements of the powerful integrated graphics, using the typically beefier VDDCR voltage plane is safer. The voltage rail can technically work in regular or bypass mode, but only regular mode is available. In regular mode, the voltage is managed by the integrated voltage regulator and derived from the VDDCR voltage rail.

Despite of this, I think that the iGPU current limit is a percentage of what you set on CPU TDC/EDC, since HWinfo sometimes reports GPU being current limited despite CPU TDC/EDC being nowhere near their maximum ratings. Increasing CPU TDC/EDC limits greatly reduces how often the GPU is held back due to current limit being triggered, resulting in a measurable performance improvement.

I can't find public information about what exactly limits the iGPU, so all I can do is test and speculate.

I'm not too worried about setting 250A EDC since this is just for short periods of time (which afaik is fine for power stages); for long periods of time TDC applies.

I set CPU EDC/TDC limits on windows with ryzenadj, maybe doing it that way is different than setting it on BIOS and that's why I didn't notice a performance difference between 4.03 and 4.08 but I must admit that I didn't test 4.08 thoroughly for performance.

There's a new BIOS firmware 4.10 since last Friday available on ASRock website. Highly recommended for anyone running Linux on the X600.

One issue this version addresses is some file corruption that would occasionally occur on Linux if you have 1 nvme disk on the main M.2 slot while the secondary M.2 slot in unpopulated. This problem was thoroughly discussed on this thread on the kernel's bugzilla. ASRock got involved at some point and they shared this 4.10 with the kernel folks and it was confirmed that it solved the file corruption issue.

I don't know if/what other things changed in this version in comparison to 4.08, but for anyone running Linux and with a single nvme disk installed on the main M.2 slot, you should upgrade ASAP!

Lol, I've already added it to the online sharing directory since yesterday but didn't see the point of mentioning it specifically here because they only concern Linux users (data corruption issues with certain NVMe SSDs, I've been aware of this for several months), and what's more, this new "4.10" BIOS has been officially available on the official DeskMini X600 BIOS support page for almost a week... So, you're a bit late coming forward (not to say: waking up) about this.

But for me the best BIOS will now forever be the "4.03.MEM01" version, because ASRock is in a bad way at the moment and is literally making fun of some of the DeskMini X600 users, because since the last BIOSes released later, their BIOS engineers have voluntarily removed the "Performance Mode" option and voluntarily blocked/bridled the maximum consumption of APUs (and their iGPUs by extension) to 150 Watts maximum under the pretext of "protecting their motherboards", this is literally a joke and is unacceptable, especially when they dare to sell this product with marketing arguments put forward such as CPU Overclocking (Cores and SoC), RAM and iGPU, they must have suspected that 150 Watts maximum would not be sustainable for an APU such as the Ryzen 7 8700G (and I even doubt it for the 8600G), so the result is CPU performance and iGPUs are completely massacred and stifled by this forced restriction to 150 Watts max.

I've mentioned this to them in many of my latest emails to their support team. I've tried to negotiate a compromise (a hidden option in the BIOS, but prior to activation, I'll give a clear warning that the warranty will not be covered in the event of hardware damage). But they won't listen and clearly don't care. So, those like me who loved ASRock's AMD DeskMini line for its customization, tweaking, and overclocking capabilities... You can forget it. We're now being left behind. They clearly don't care about us (and here I'm thinking of those left behind with the DeskMini A300s). So, for me, enough's enough! F**k them! I'm going to migrate to a premium miniITX platform with a compact GaN power supply, and certainly not from ASRock. I won't have to deal with the limitations of the DDR5 SO-DIMM format and other annoying drawbacks that were linked to the miniSTX format and sometimes even directly to some of ASRock's stupid and outdated designs.

But in any case, one thing is clear: if they continue on this path with a shitty policy of only looking out for their own interests, using marketing that ultimately becomes deceptive, and ignoring their customers' needs, then they will gradually have all their market share in the miniPC sector eaten away by Chinese brands such as Minisforum, GMKtec, beelink, GPD, etc.

Hi Gents!
Thanks to this forum and this thread in particular I have cooked me an x600 mini instead of and old HP Elitedesk 800 G1 mini
I have basically followed the recipe from this thread and here is what I have:
X600 mini stock bios 2.03
Ryzen 8700G
2x16Gb Kingston Fury Impact KF564S38IB-16 that run on it's native 6400 from XMP profile selected in BIOS
AXP90-X47 FULL with stock fan
Arctic Cooling MX-4 thermal interface
Intel WiFi 9260 AC
Kingston A2000 SSD
Stock AsRock PSU
All stock i.e. no overclocking except CPU Curve optimizer set all cores -40 in BIOS.
+USB2.0 board and rear audio jack from Ali

And in reality I'm fully happy with the build but 2 points below so I would be more than grateful for comments and directions on where to dig:

1. Temps. It keeps around 40C idle and when I run a stress test it gets to the 90C in around 1 minute and 20 seconds and stays at this temp forever. It does drop the CPU power from around 86W to 81W and that is it. Fully stable here, no throttling according to the monitoring tools (OCCT).
I double checked the CPU-to-Radiator footprint and it is absolutely OK (20+ years of experience with computers), the fan profile is to Standard so I do hear it spins up and the monitoring confirms this.
So the question here i have - is this normal behavior? I expected lower temps on this CPU-cooler pair or am I wrong?

2. Fan noise. The Thermalright stock fan is noisy... and still noisy at CPU temp 40C where BIOS keeps it at 1700rpm. Do i need to update BIOS for more aggressive FAN speed adjustments or something else?

My future plans are:
1. Install memory heatsinks (came from Ali, same as mentioned in this thread), btw, those who istalled ram heatsinks, did you use stock thermal adhesive or replaced with something, why I am asking is because the chip in a middle (SPD I believe) is around 0,5 mm higher that memory chips so the heatsink will not go straight forward..
2. memory overclock, to maximizethe iGPU performance
3. Install 120mm fan, I've bought the Silverstone Air Slimmer 120 and it fits basically same way as the Thermalrigt stock fan, but thinking of some nice way to mount it. I remember somebody mentioned about 120mm fan in x600 mini but can not find the post.
4. Install 2x40mm fans to improve hot air exhaustto the perforated side of the mini's case, ordered 2 noctua 40x10mm PWM fans.

So i apologize for long post, but it's kinda introduction + questions: 2 in one
