Motherboard [16/05/2025]ASRock DeskMini A/X300 BIOS - "P2.10.SL02"(Curve Optimizer fixed & native S3) & "P2.10B"(ACS) & "P2.10" for X300 - AGESAv2 Pi "1.2.0.E"

And about the EMI interferences: SS comes from an age of analogic world, with AM radios and antenna TVs. There is now far more interference from your pulse modulated 4G or 5G phone, wireless modem, bluetooth and any intelligent metters than from a computer mainboard placed inside a Faraday metal cage. Even the speakers can receive the phone pulse signal when near and cable digital TV and FM radios become noisy or generate artefacts due to wireless communications ! It is just pointless now to modulate the main clock signal. I first tried to edit the BIOS myself and i saw that the options are only xx% BELOW the standard base frequency. Then I asked Asrock suport and they sent me P1.80 and this P2.1 BIOSes with SS disabled because they have no option likie all other motherboard producers.

But is not my job to convince anyone, just don't deactivate it, or don't use this BIOS. It is already a wery interesting new world in which people belive an experimental database with the AI name instead human experts. I am quite shocked that people are starting to belive ChatGPT...

When I received this BIOS I was so happy that I finally can see the rounded clock frequencies in CPUz or HWMon that I have decided to register here and in Win-Raid forums to share the BIOS with other people. By the way, I am the one which discovered the CTRL+Q hidden BIOS options on X300.

Ok, thanks for clearing this up for me. I will stick with the S3 BETA BIOS for now as long as it works since S3 is more important to me than disabled SS. If a BIOS with both appears I will switch.

You can try to contact Asrock Support at this e-mail: Asrock_TSD@asrock.com.tw and ask for a custom BIOS with both disabled. I was not interested on S3 support.

Do you know if the Curve Optimizer settings for CPU and iGPU, and SoC/Uncore OC mode in that Advances CTRL+Q menu work again with this new BIOS?

They are present as options and should work, but I have not tested them because I prefer to set PBO overdrive to manual and 1x to use the CPU at maximum default without overclocking or underclocking.

I have a 5600G with a "Be Quiet Pure Rock LP" 92mm cooler and 1.35V Muskin memory and it can do video compression for days without overheating. Before, I had the classic "Noctua NH-L9a-AM4" that was VERY BAD and Kingston laptop 1.2V memory that worked with errors in Handbrake. It seems that AMD desktop processors need 1.35V laptop memory to work correctly...

Well, those options are present in 2.00 and 2.10 and do NOT work, they aren't correctly saved, thus back to default after reboot. I'll try myself when I've time.

Hi,
Excellent work collating all these BIOS

However for my x300 I'm not having as much fortune...

Ive tried a lot of the BIOS files shared on uploadnow.io but none of the settings are sticking past a cold reboot for me.
Other avenues tried - new CMOS battery, reseating and removing sticks of ram.

I'm sure there was a version that retained the settings at some point but now it seems that all versions are failing, is there some Reset state that needs to be cleared?
I'll try anything!

Thanks

5600g
2 x sata
1 x mvme (boot)
8 x 16gb 3000mhz (XMP)

The above has been solved by Asrock Tech support.
The CMOS battery used has a non-standard polarity connector.

I just blindly bought a CMOS replacement which didnt save BIOS changes between boots. Asrock kindly sent me a new battery and all is working now

The latest S3 beta chrashed on me, so I'm using your beta without S3 and SS disabled. Thanks for sharing!

Is there any way to increase the RAM voltage to 1.4V or 1.45V? I want to maximize my RAM's performance.

No, sorry there is no way (some people with knowledge of BIOS modifications have even tried without getting any results), it seems to be hardware locked unfortunately, it is 1.20v or 1.35v, these are the only possible settings that's all.
