New AM5 BIOS updates now available

   I know it's a known issue. I also know it is a KingBank issue. The info about
what the problem is can be found with a quick google search. I am afraid I don't
know if ASRock has resolved the issue with newer BIOS updates (4.10 was still effected).
Unfortunately people tend not to bother reporting when an issue is fixed. Most people
effected simply rolled back to BIOS version 3.50 and I suspect KingBank has since
corrected the issue on newly produced modules.

If you have tried the latest BIOS for your board and it still won't POST with
an effected KingBank RAM kit then your only option may be to use BIOS 3.50 or
look into getting an RMA from KingBank themselves. I know it's frustrating but
this issue is 100% KingBank's mistake. ASRock's BIOS implementation is not broken
or defective in this case, it simply exposed a mistake in the effected RAM module's
firmware.

	So, what?�s the situation? Asrock noticed a problem with KingBank memory on Hiynix M?�Die chips? KingBank is already a huge brand that needs to be taken into account, and it?�s essential to ensure compatibility with these modules.

	In the end, was the problem resolved by reinitializing the GPU via its software?

	Thanks for the info ImbaDakula, I will point my contacts at ASRock to this thread. It would be helpful if you could list your full system specs including OS. Edited by Xaltar - 17 Aug 2026 at 6:15pm

	My new 9950x3d arrived, the old one degraded and I sent it for RMA in the meantime I used the 7600x. What I want to emphasize is that I am on the latest bios 4.43, but unfortunately the old BUG is present and it is not clear to me how none of the Asrock designers or the people who implement the BIOS noticed this, and the BUG is present in all BIOS versions. The BUG appears when you apply your PBO settings in the bios, in case you change your mind and want to turn off PBO, more precisely in the settings where it is enabled, you click to disable it, but there is no change!! Although PBO is disabled, it continues to work, which you can check with the Ryzen Master application, and you can also test the CPU with various programs and you will see the same performance and the same behavior of the processor. If you want to turn off PBO to be totally inactive, you have to go to LOAD UEFI BIOS DEFAULTS option, or reset BIOS! A lot of people think that the disable PBO option actually turned off the PBO, but it didn't, I even recorded a profile with the PBO settings disabled, but when loading the profile with the PBO off, the board continues to behave retardedly. What I wrote is easy to implement for anyone who wants to test, except for Asrock engineers who don't think to test the options they implemented in the BIOS!!!
