Most, if not all, AM5 boards should already have the newer Secure Boot Key stuff. Most ASRock AM4 boards got the updates late last year. X300M-STX (also known as DeskMini) got it early this year. |

I suspect we will see a lot more boards supported after celebrations for the Lunar New Year are concluded in Taiwan. This is why I made this thread, so we can track which boards are still waiting then ASRock can see them listed here based on demand rather than just a list of models in house. Maybe it will help with prioritizing which boards work on next. -------------

Hi! Tried the 4.07.AS01[Beta] on Taichi X870E and my rtx5090 could no longer display 240Hz in 5120x1440p. It switched to 120Hz and when I changed it back to 240Hz the resolution changed to 3840x1440p. Flashed bios 4.04 and I'm back to 240Hz 5120x1440p, so something is not kosher with the 4.07 beta. |

Thanks for the info Dr_KrillE, could you share your GPU model and brand so I can ask ASRock to check out this thread. They will need your full system specs. That said, you may want to wait for 4.10 for your board, it may be resolved there. I will pass the info along anyway incase they don't already know about it but that will have to wait till next week when they all get back from their Lunar New Year holiday period. -------------

Hi everyone! I?™m currently setting up a system with a Ryzen 7 9800X3D on the ASRock B650 PG Lightning (the ATX model). ?‹I?™ve noticed that the Micro-ATX version (B650M PG Lightning) received the v4.10 update with AGESA 1.3.0.0a on February 12th to address the recent boot failures and stability issues with Zen 5 X3D chips. However, the support page for the full ATX board is still only showing v4.03 from December. ?‹Does anyone here have any info on when the stable 4.10 or a Beta (like 4.07.AS01) will be released for the ATX version? ?‹I want to make sure I have the safety fixes for the 9800X3D ready before I mount the CPU. Thanks in advance! |

As far as I am aware all AM5 boards will receive the 4.10 update. Last I heard from my contacts at ASRock, they are hard at work getting them all ready for release. I suspect over the next few weeks we will see the remainder go up on ASRock's website. -------------

Yeah, probably because they are trying to get them out quick. They haven't been added to all the relevant product pages yet. It will happen once the pressure is off to get them all out I am sure. The page I linked is where they will all be put up first, after that they will be updated where necessary on the rest of the website I think. Thanks for the heads up -------------

Hi Y'all! Just a little feedback on BIOS v.4.10 I can report that the problem with GPU and res/update freq is gone, and it works as it should again. After a bit of testing it seems stable with both PBO/CO and EXPO enabled. In the act of testing some mem overclocking and that as well seems to work fine. So no issues as of yet ;-) BR ------------- //Dr.K ASROCK X870E Taichi AMD 9950X / Arctic LF3 420mm AIO G.Skill Trident Z5 Neo DDR5-6400-64GB-CL30 ASUS ROG Astral LC RTX5090 OC Corsair MP700 Pro 1TB BE QUIET!

> Is anyone still waiting for an update for their board? DeskMini X600 is still at BIOS 4.14 / AGESA ComboAM5 1.2.0.3g. Well I suppose the X600 chipset-less design is different, hence the different version numbering scheme. But they already skipped the AGESA ComboAM5 1.2.7.1 update, I wonder if they already dropped it off their support list... |

Interesting, I don't think I have seen a single report of boot issues (00 code or DRAM/CPU LEDs lit) on x600 based systems. Given they were designed for thermal management not outright performance it could be that the update isn't needed. I will see what I can find out. -------------

The X600 ITX contained in the DeskMeet has already received the AGESA 1.3.0.0a update so the X600 STX in the DeskMini should receive an update too. -------------

I?™m encountering critical overclocking stability issues with my ASRock X870E Taichi OCF (BIOS 4.10) paired with an AMD Ryzen 9 9700X and Biwin Origin Code 48GB?2 DDR5 memory. Here?™s a detailed breakdown: Memory Overclocking (8000+ MT/s): ??A2 Channel (2 DIMMs): Boots and tests stable at 8400 MT/s without issues. ??B2 Channel (2 DIMMs): Fails to boot even at 8000 MT/s (no POST). ??Dual Channel (A2+B2): Cannot boot at 8400 MT/s; struggles heavily to pass stability tests even at 8000 MT/s. ??Memory Refresh Mode: The option to set Normal mode is locked/unavailable in BIOS. CPU BCLK Overclocking: ??CPU base clock (BCLK) can only be stable at 105 MHz or lower. Any value above 105 MHz triggers error code 22 on POST. Memory Divider Overclocking: ??Attempting to reach 8400 MT/s via memory divider results in an immediate error code C5. Has anyone else experienced similar issues with this CPU/motherboard/BIOS/memory combination? Any suggestions for troubleshooting or BIOS settings to resolve these stability problems? Optional Short Version |

I am afraid I haven't been active in the overclocking scene for quite some time. I don't have much to offer suggestion wise. What you describe does make sense from an overclocking perspective however. It's always easier to overclock a single RAM module than a pair. The fact that your B2 channel isn't able to match the A2 channel tells me that your IMC's A channel is more capable than channel B. If this is the case then it's highly likely that you won't be able to push it any further in dual channel regardless of settings. You would need another CPU with a stronger IMC. Back when I used to chase overclocking records I would often go through over 20 CPUs to find one that could handle the settings needed to achieve my goal. From what I have seen of DDR5 clocks on AM5, 8000 MT/s is pretty decent but I am guessing by the fact you picked up an OCF board that you are not looking to settle for decent. If you have access to more CPUs to try that would be my first stop. If not I have a feeling you have hit the limit of the IMC on that CPU. My guess would be that you will find stability probably at around 7600 MT/s in dual channel. Combining both channels never yields the same clocks as the weakest channel due to the added load and heat going through the IMC. Typically you can expect between 80% to 90% of the maximum stable clock of the weakest channel when using dual channel. I am sure this isn't what you wanted to hear but it's all I have to offer. There may be other forum members that have more recent experience and possibly some tricks I am unaware of. You can additionally ask ASRock themselves by opening a support ticket: https://tw.asrock.com/events/tsd.asp Though I suspect they won't be able to help much if at all. Good luck -------------

Thanks brother! I?™ve already tried two Ryzen 9 9700X CPUs, and both ended up with the exact same result. The current CPU I?™m using can run DDR5 16G?2 at 8400 C34 with tight timings and pass all stability tests on another motherboard, and it can even boot at 8600 MT/s (maybe 8800 too). So right now I?™m not sure if it?™s still an IMC limitation of the CPU, a motherboard compatibility issue, or just some BIOS settings/ODT configurations that I haven?™t nailed down yet. I?™ll keep experimenting further. Appreciate the help! |

First, my 9600X stopped working. I put the PC into sleep mode before bed, and in the morning it wouldn't turn on again, with a CPU post code. I tried a lot of things, including FlashBack and clearing the CMOS, but nothing helped. I bought a 9700X, installed it, and everything worked right away. Later, BIOS 4.03 came out, and I updated it via FLASH INSTANT, but the PC wouldn't boot; it had a black screen and froze on the CPU. I spent three hours trying to get it to work (swapping memory, clearing CMOS, and trying to flash version 4.03 via FlashBack. Sometimes, after clearing CMOS, an image would randomly appear. I could even enter the BIOS or even start the system booting. But then everything would freeze, display random errors, or just freeze). I was very upset because I thought the 9700X was broken too. But then I decided to try reverting BIOS back to 3.40 via FlashBack, and lo and behold, everything worked correctly right away. The first boot was slow (about 40 seconds), but then everything worked fine. Then version 4.07.AS01 was released, and I didn't install it. Today I saw that version 4.10 was released and decided I should try installing it. And I ended up having exactly the same problems as before, only the system booted intermittently. Immediately after the update, the system froze on DRAM. I powered it off and back on. Same thing. I powered it off, cleared the CMOS, powered it on, and the image appeared. I was even able to enter the BIOS, clicked "Load EFI Defaults," and when I exited, I clicked "Save," after which the system froze. Powering it on again results in a black screen and CPU (it's completely unclear where it is, because the first two lights are on at the same time). I've tried many options. Immediately after clearing the CMOS, the system boots, passes all POST codes, but then randomly it either freezes on the boot screen, or sometimes it starts loading but immediately crashes with the ACPI_BIOS_ERROR 0xA5 error. After the freeze and a second reboot (with a power outage), everything freezes on the white VGA LED. This continues until I clear the CMOS. I also tried re-flashing 4.10 using FlashBack, with the same result. Sometimes I can enter the BIOS after flashing, but sometimes I get a black screen. As soon as I flash 3.40 via FlashBack, everything starts working correctly. I tried flashing 3.40, resetting the settings, saving, and then entering the BIOS again to flash 4.10. It still freezes on boot after flashing 4.10 (or it enters the BIOS but freezes when trying to save the BIOS settings). I don't know what to do anymore; I have no warranty :( And there are no service centers in my country.

This is likely caused by a known issue with KingBank RAM. KingBank has an error in it's firmware that causes an issue with 4.xx BIOS versions. The issue is that "Mixed Mode" in previous versions was set to normal by default but on the newer 4.xx BIOS the default is "auto/default" which = enabled. Check under: OC Tweaker-> DRAM-> Change Refresh Mode = set to Normal See if that resolved your POST issue. It also explains your previous issues after updating. You can open a support ticket with KingBank if you like, they may be able to help resolve the issue at the firmware level. That said, flashing RAM firmware can result in bricking the RAM and needing to replace it so the workaround may be the safer bet. Mixed mode is the superior setting but owing to the issue in KingBank RAM's firmware it won't work as intended and causes the issue you described. -------------

| you are misleading the user. In firmware version 4.10, the usual asrock refresh mode does not turn on under any circumstances, this is a bios problem. |
Posted By: Xaltar
Date Posted: 23 Mar 2026 at 8:53am

AGESA 1.3.0.0a introduced bank refresh modes and defaults to "fine granularity or mixed mode" when set to auto. This is not ASRock specific. I believe some brands have released updates to force the default to "normal" mode when auto is selected, as a workaround for the issue. The problem is caused by RAM manufacturers not board manufacturers or AMD. That said, a BIOS level tweak can be implemented as a workaround. I have no information as to whether ASRock will do so however. The default, as set by AMD in their AGESA, is intended to provide optimum performance by utilizing the best secondary timings the RAM supports (TRFC1/2 and TRFCSB). On some kits these timings are improperly inputted or are simply incorrect, KingBank being one of the manufacturers with the issue. In prior BIOS versions (3.xx and earlier) these incorrect timings were ignored. There is a much better explanation here: Sorry if I wasn't clear enough in my description but this is the issue I was referring to. -------------

Before updating to 4.10, I wanted to check where this setting was in 3.40 so I could quickly change it (since the PC could freeze at any moment). But I didn't find this setting in 3.40. Will it only appear in 4.10? And another question: after I manage to switch to Normal, will I be able to set the correct timings (TRFC1/2 and TRFCSB) in the timings settings and then switch back to Auto? Or are these timings not editable? And is there a way to find out which timings are "normal"? |
Posted By: Xaltar
Date Posted: 25 Mar 2026 at 11:38pm

AFAIK the function was added with AGESA 1.3.0.0a so the setting likely won't exist in 3.40. As for checking your timings, use a tool like CPUz or ZenTimings to see what your system is currently set to. ZenTimings will allow you to read the RAM's stored settings but bare in mind, some of these are incorrect (hence the POST issue). You will want to just look at what settings are currently being used by the system and are working under 3.40. I believe you should be able to input the correct timings and thus enable fine granularity once done (best performance and efficiency). If you are able to get the system to POST even with the issue then you can experiment a little until you find what works best for you. There are a lot of tutorials out there on getting things set up safely and with the best possible performance within that safe range. Unfortunately I am not overly familiar with fine tuning DDR5 as all my current systems use DDR4. You may also want to consider opening a support ticket with KingBank and see what they advise you to do. Good luck -------------

That's the question. You're writing that Kingbank has incorrect RFC timings. But I'm looking at the SPD timings on 4800 (2400) and don't see anything out of the ordinary. I'm using roughly the same timings now on 3.40, only on 6000 (3000), and everything works perfectly. That's why I'm not entirely sure what specific bad timings you're talking about.

I remember seeing someone report it being RFC2 that was out of spec in particular. RFCSB too I believe and it fits with what I am seeing in your screenshots. Comparing your actual working subtimings with the JDEC subtimings you can see RFC2 is significantly lower in the JDEC listing than the value shown in ZenTimings. tRFC2=480 in the ZenTimings screenshot vs RFC2=384 in the highlighted JDEC for 2400. RFCSB is also too tight in the JDEC listing, 312 vs 390 in the working timing list. RFC2 should be 480 or higher, I hear 550 is a good safe number. RFCSB should be 390 or higher, again 550 would be fine here too. You can always try to tighten things up to 480 and 390 to match your current working settings once you have the system working stably and reliably. -------------

Given that you are able to make the system POST at all with the subtimings set as they are in the JDEC I would guess that they are not too far off the mark, enough to be a problem though. -------------
