Crosshair VI Hero: UEFI build update thread

Level 13
Directly from Elmor:

Beta BIOS 3008 for C6H/C6HWIFI/C6E:

AGESA, 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



Test BIOS 0083

Same as 0081 but with "2T" DRAM Mode when using above 2666 DRAM Ratio.

at least with linux, you dont have to wait for a bios update to load up the latest cpu microcode. So there's that for the people who dont plan on updating their bios for various reasons. I believe microsoft does the same but i'm not sure how often those get pushed out.

- Supports NVMe RAID (mainly useful on C6E)
- Q-Code LED Function option to turn off the Q-code display after POST

Original post:

that was pretty fast. probably going to test it... 6002 was stable at least like the others so far...
Having an ASUS board?
Increasing the Capabilities in your Digi+ VRM can prevent your hardware from being shut off (relaxes over-current condition).
Do it if you DID NOT set bad settings but didn't get it stable. (i.e. your hardware is for overclocking, high destiny, whatever).

Seems stable more than 6002

Did you try?
AMD Ryzen 7 1800X 3.6 GHZ (NOCTUA NH-U12S SE) ASUS ROG CROSSHAIR VI HERO (Sapphire Nitron+Radeon RX 580 4G) G.SKILL Flare X DDR4-3200Mhz C14 32 GB (4x8GB) Samsung 970 PRO 512 M.2 SSD \Samsung 850 PRO 512GB 550MB-520MB/s Sata3 SSD

just testing

What is eCLK mode?

Just preordered my ryzen 7 2700X gen2 processor

Separate clock for CPU core and rest of devices (PCIe, USB, SATA, IMC).

Bios 6003 (installed 13.4.2018)

I needed to flash the file two times.
The CPU cooler wasn't recogignized. Q-Fan faild, Post screen error No CPU cooler found.
CPU cooler was running at 100%

After a reflash, its working nicely. No BSOD or anything so far.

That has always been something I would recommend with this board. For whatever reason, a single flash is not rarely reliable. This goes way back to the fan and pump failure issue and has been present on the board since the 1xxx series BIOS's. Load defaults, flash, boot to BIOS, load defaults, flash, and then you should be good to actually start setting things up normally.
