Crosshair VI Hero: UEFI build update thread

[Raja@ASUS]

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 (405200c4e299c1eed9a0044edec9aba51f37cee1d70caabe4 0b9485b0604521a)

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.

Great work Raja/Elmor.

Could you maybe explain a little about how we would recognize if we needed 1T or 2T.

I have just read up what it means , just really want to know how i would notice if one is better than the other.

Is it a case of , on the 5xxx bios i could clock to 3200 , but it was unstable , and now on 0902 anything above 2133 is 0d .

Many thanks

In your case try the 1T UEFI with below 3200MT/s then. If it works, good, if not, flash the 2T one. Basically the 1T UEFI can(!) provide better performance, but with higher risk of RAM stability. Though some systems might be more stable on 1T with lower MT/s setting.

I've found better stability with 1T on my Corsair Vengeance LPX.

More bios please i want 3000mhz with my Corsair CMK16GX4M2B3000C15, dont sleep, work 24/7.
I only can do 2700mhz.

[MeQira]

I've tested 1001 and it's look great than other versions. I have 2x8 vengeance led 3200. I can boot with 3200 mhz. Normal boot can't start windows but can control bios so no need clear cmos and if i use slow boot from bios, i can start the windows. It's not stable but i saw that i can use my rams with 3200 mhz on this mainboard. I can control fan expert from windows. Temp still 60 celsius, voltage looks stable (if turbo 4.1ghz normal with 1.526 volt) If i use 3200mhz system freezes for seconds. But its really stable with 2133mhz, and there is no freezes. I'll try gaming and i'll report here if there is freezes. Thanks a lot!!! http://i.hizliresim.com/nRM185.png

Heck yeah!! My CMK16GX4M2B3733C17R kit went straight to 1T after rebooting 1001. Then I've upped the MHz from 2666 to 3200 and looking for 3400 with a future build.

[Jonorees]

Will either give better / worse M.2 compatibility or no change?

[Raja@ASUS]

No need to thank me. The work is all Elmor/Shamino and team.

1T is better for performance, but technically, also more difficult to get stable. Use whichever build suits your setup.

[Crayraven]

1001 causes my pc not to post if I use the xmp settings. But 0038 works fine. I guess my memory doesn't like 1T.
