Bios mod Asus 470x-F




Currently modded:
  • Unlocked CBS menu
  • Unlocked VDDP in AI tweaker
  • Spread Spectrum disable option AI tweaker
  • Fan Stop options in monitor
  • Some CPU features unlocked
  • Also modded the 1000/2000 side of the bios so everyone can have some fun.

Two months ago I decided to learn some things about modding my bios. After a lot of testing I've decided to share this with you guys. Now I know the basics I want to learn more in the future. Let me know if you're missing something, have some modding advice and the experiences you have with this mod.

Use at your own risk, I'm not responsible for any problems. Don't modify options you don't know.

You need to follow the instructions using Flashrom here https://www.overclock.net/forum/11-amd-motherboards/1733304-agesa-fw-stack-patched-bioses-3rd-gen.html especially this post https://www.overclock.net/forum/28128500-post4.html. After making a backup of your bios use FD44Editor to copy your serial number etc. to the new bios https://www.overclock.net/forum/28139368-post274.html.

Don't forget to edit your own UUID, MAC and Motherboard S/N before flashing with flashrom

Download Asus 470-F 5406 mod here: https://drive.google.com/file/d/1OIBeq866lFpaUUz190himkSI53iOQLSU/view?usp=sharing

Recomendations:
Bios guide from Verangry on ComputerBase, all the settings are available now (German, use google translate if needed). Nice community!
When I use MBIST I get wierd errors so be careful with that.
Advanced settings from Dram Calc, also shown on one of the screenshot (memory training)
I hear a lot of people complaining about Asus removing AMD Cool&Quiet. It's not removed, it's enabled by default and has a different name. Don't worry about it.

  • Fan Stop options in monitor
hey there. is it possible to stop PWM fans with your mod if reading temperatures are low? it's so lame that the original bios can stop only DC fans.

ps.
btw, it would be great if you add an ability to create a custom curve for CPU_OPT fan, if I remember its name correctly. one more lame thing from ASUS creating a 4-pin controller and no actual control for it.

  • Spread Spectrum disable option AI tweaker
good thing for overclocking. my CPU was totally unstable with Spread Spectrum enabled. however, I cannot imagine a decent overclocker flashing his bios and using auto OC at the same time :)

I'll probably check the next version with the CPU_OPT control implemented. It would be great if you edit your first post adding screenshots from bios and explaining the exact features you've unlocked (best if examples of usage included). thanks for doing it, good well-round mobo.

Hey Eder,



you modded/enabled a few more things than sexysale and myself back then. Nice!

Would you be so kind to post some screenshots of those additional settings?


Greetings

When @The Stilt released the modified Flashrom and you guys came with the Spread Spectrum mod it inspired me to learn some bios modding so thank you! :thumb:

I've added some screenshot.

Ha! I'm currently using auto OC, my 3700x boosts to 4450. I want to try some CCX overclock. If only we had some decent bios options for that (investigating).

Ok about CPU_OPT. I found that just like AIO_PUMP/W_PUMP+ all the settings are coupled. I don't know if it's possible to separate them. I'm currently learning about modifying menu's so I don't think I'm skilled enough to tackle this issue (yet). Example below.

well, it's great enough that you've made it possible to stop the PWM fans. I've already sent the request for that to asus support, but they may ignore it easily.

could you please add some short explanations of the unlocked options? best if these explanations would be shown down below in the bios itself, if it's simple enough to do. also do you consider to mod newer versions of bios when they're out?

just flashed mine. so many options, it's insane! as for fans: should I manually set duty cycle to 0% or enabling fan stop option will stop them automatically when temperatures are low enough? was it hidden option or you've made it by yourself?

thanks a lot, this is huge!

Awesome - thanks for the screenshots!

So the CPPC preferred cores setting was actually hidden and not a "X570-only" feature? Well, thanks a lot Asus! -.-


Edit:

I flashed it and it's working fine. No issues here.:thumb:


Regarding Cool´n´Quiet...
Source1
Source2 (~1:26:08)
Haha I've read somewhere a vendor put the option back in. Thanks for the feedback! I'm glad everything is working for you.

The Fan Stop option should stop the fans when the temperature is below the Lower Temperature settings. For example when you put 30 in the Lower Temperature the fans stop when a temperature is measured of 29.

thanks for your answer :) one last question though: how can I get into memory training section which can be seen on your screenshot? I cannot find it for some reason, even though I see «DDR4 Common Options».

You're close. It's in the Phy Configuration/PMU training.

Hi,
I have a problem with USB 3.1 I'm getting max 20mb/sec where on Intel mainboard is 200mb/s. Is there any USB options in your MOD that can solve speeds on USB 3.1?

Did you manually install any ASMedia USB driver package?

Try out "pure" 1.16.59.1 Asmedia drivers
I had to manually point windows to the right direction for the correct AMD Sata Controller driver instead of a generic one. Wouldn't surprise me if something simular is happening with the USB drivers.
