Directly from Elmor:

Beta BIOS 3008 for C6H/C6HWIFI/C6E:

AGESA 1.0.7.1, temperature offset fixed after S3 resume, GPU Post function fixed, 0d with some GPUs fixed

C6H Test BIOS 0020 with AGESA 1007 (405200c4e299c1eed9a0044edec9aba51f37cee1d70caabe40b9485b0604521a)

In order to get back to an older version after flashing, you have to use USB BIOS Flashback.

Let me know how it works for you, especially regarding cold boot issues. Any confirmed bugs in the bug report form please




Beta BIOS 1501

* Workaround for some CPUs stuck at 22x ratio if using override voltage
* Fixes PCIEX4 bandwidth setting getting lost after power is removed
* Same DRAM boot behavior as 1403 (no cold boot fix)
* Same DRAM profiles as in 9920
* Still has the Vcore value issue when booting with Offset Mode and switching to Manual Mode

UEFI build 9920 for the C6H:

* Improved DRAM cold boot, results in slightly longer POST time
* Fix for CPU Ratio stuck at 22x on some CPUs when using Vcore override/offset
* SenseMi Skew is now Disabled by default. If you want to return to previous behavior set SenseMi Skew = Enabled and Offset = 272.
* Added DRAM profiles for Samsung B-based DIMMs with tuned subtimings, including The Stilt's settings



C6H beta UEFI 1403

* Fixed W_PUMP and AIO_PUMP speeds during POST
* Fixed Fan tuning sometimes failing
* Fixed a few issues with AMD USB3.1 ports
* Some tuning on DRAM settings, let us know how they work for you. tRDRD_Sc is still at 5 above 3500 MHz as it helps with stability. For performance you want to force this to 1. We'll consider changing this in future releases as the performance impact can be quite noticeable in certain applications.

An update on DRAM Boot Voltage, currently it should be 1.35V by default if the DRAM Voltage is changed. So if you're setting DRAM Voltage to above 1.35V, you might want to sync this setting. Additionally there might be scenarios where you will have better luck by syncing DRAM Boot Voltage to DRAM Voltage even at lower values.




AGESA 1006 RC4 official UEFI 1401

Just tested quickly 3600 memory and cold booting, seems good but you guys are going to have to help me test this before we have a judgement. Seems CPU temp reading from SIO now has -20*C offset for XFR enabled CPUs.





UEFI build 1107





Older test builds:


Test BIOS 0079

Test BIOS with new AGESA 1004a, with a couple of bugfixes. Up to 5% performance increases in specific applications. Also has P-state overclocking working with BCLK increase. If you want to keep C-states, make sure to set Advanced\AMD CBS\Zen Common Options\Global C-state Control = Enabled. There are two new settings under AMD CBS\UMC Common Options\DDR4 Common Options\ you might want to take a look at, Fail_CNT and ProcODT. Fail_CNT decides how many times to retry when DRAM training fails (F9 -> 0d), default is now 1. ProcODT can help improve your DRAM overclocking. There's a setting available also on previous BIOSes under AMD CBS\UMC Common Options\DRAM Memory Mapping named BankGroupSwap. If you have 2x Single-Rank modules you can try setting this to Disabled and you might see some performance boost in certain applications.

Test BIOS 0081

Same as 0079 but has ProcODT default = 53.3 ohm

Test BIOS 0082

Same as 0081 but with a DRAM compability patch for the below part numbers

I mounted the 5900x with the bios 8503, it works perfectly 😉
Alex656: What board did you achieve this with, a C6H? and did you use the latest chip-set for the installation? Great NEWS!

Yes, i have a Crosshair VI hero (not wi-fi); for the installation I updated the chipset drivers and the bios with the old processor (3900x), then I installed the new one; it works very well, the frequencies in single core reach 4.95 Ghz with PBO active in single thread; on cinebench I get similar results to online reviews. I am very satisfied considering that I can use a top cpu in 2022 on a motherboard purchased 5 years ago!

Finally we have support for our motherboards, but i'm having problems with usb ports still.

My 5900x works with CH6 but the cpu it's not listed as compatible, weird.

Ryzen 9 5900X is on the supported list for the 6 Hero, near the bottom (on the ASUS product support page).
A bus station is where a bus stops. A train station is where a train stops. On my desk, I have a work station…

Just want to say a big up to Asus for finally supporting Ryzen 5XXX series. I went and bought myself a 5900X because of this. Otherwise I would have kept my 3900X and waited for next gen MB's.

AMD should be thanking you really 🙂

Anyway I am happy.

AMD was the one to mix their "AM4 socket support" to "chipset support" and deny any Zen3 support on motherboards with AM4 sockets but with 300 series chipsets. Asus just had to comply.
So, no need to thank Asus, thank AMD for unbreaking their support promise.

1. Update AMD AM4 AGESA V2 PI 1.2.0.7.
2. Improve system stability
3. Fix AMD fTPM issue causes random stuttering.

Have you tried to use bios renamer?

Clear CMOS, or remove the batery of the mobo?
