It drops out fully, sometimes for a short time sometimes a very long time. My Yamaha USB driver control panel flashes a big "USB Signal Error" warning sign. It works perfect with 2901 and all earlier...

I use USB soundcards and bios 3004 is spamming USB errors to the soundcards, never happened on ANY earlier bios. Makes the soundcards unusable as the sound drops out. Changed back to bios 2901 and...

I set everything in bios, PBO is broken that's why I set all values to 0 so it defaults to motherboard limits. Ooh, and scalar is 10x. And PE is level 3.

I have PBO advanced activated with 0 on ppt/tdc/EDC and +100MHz override. - 0.1V offset Vcore. It's not absolute max performance, but very energy efficient. 7330p in CB20. Running 3D Mark it's a...

Telemetry is for software to read the internal parameters of the CPU, Ryzen Master uses it, and even the CPU itself uses it to calculate it's performance. Some parameters can be set in the bios like...

There is a test bios with 1004B, it works mostly well but single core boost is completely broken.

You don't want it.

Why it's broken, when Prime/F works well, is unknown but I want a fully...

Maybe Asus are waiting for AGESA 1.0.0.4C or 1.0.0.5. 1.0.0.4B may have some problems which are hard to solve. Current bios 2901 works rather well, there should be no rush.

No, it's not the same thing.

I've had simlar problems that have been resolved by a bios reset using the button on the IO-shield, reboot, apply the exact same user profile, save, and everything works stable all the time again.

CB15 Aggressive doesn't work with C7H as well, generates a sure bluescreen. Just ignore that option! :)

It is voluntary to test, if you feel it's fishy don't. There are no guarantees whatsoever, for all I know it could eat your cat ;)

It's not on my two other boards with 1004B, seems restricted to X570 boards so far. Anyway, it's a inofficial beta, things can happen along the way.

It's from Asus, provided by the guy who writes HWINFO. It's very inofficial fyi.

The Beta works well overall, impressive multicore performance, but single core boost is very weak. That's probably why it isn't released yet. Needs to be fixed!

Biggest improvement is telemetry of...

There is a beta bios with 1004B over at overclock.net, for those interested

What is Asus is doing, is assuring a lot of enthusiasts will NOT buy Asus next time because of virtually vanishing support.

Enthusiasts tell their friends, are very active on forums and so on. In...

This is what they answered when the Germans asked:

I wrote to ASUS about 1004b

Answer is the following:

We thank you in advance for your inquiry.

1.0.0.4B is the latest bios version(AGESA), it's in bios 5406 from Asus. It's needed for the latest chipset driver to work as intended by AMD.

Minimum/maximum works as is by default(90/99%), but I...

I have a Aorus M also, besides the C7H and Prime Pro, it have had three 1004B versions already. And it is just a low end B450 board. Works excellent by the way, the 2700X I'm running on it is exactly...

The reason for delay can not likely be for pushing X570, because everyone would buy a Gigabyte/MSI/Asrock X570. No gain for Asus.

They affect boost behaviour, for AMD power plans to run optimal Global C-state, CPPC and Power Supply Idle should be enabled.

ECC is a totally different thing, it is for Error Correcting Memory...

Only I know of, both my 2700X(Aorus M) and my 3700X(Prime Pro) works excellent with 1004B. I just wish my 3900X on C7H would get it as well.

Over at overclock.net, a user posted a reply from an Asus-official today. The message was that there is no ETA for a new bios for C7H:



My low end Gigabyte B450 has already had THREE iterations...

The PCIE errors was with other vendors as well, I got an update correcting the issue for my Gigabyte board today(the THIRD 1004B-bios from Gigabyte - F50N). Sadly, my C7H still sits at ABBA-bios ...

Change the power plan settings for minimum power to 0% and you will get very low idle = slightly more silent fans. Default is 99%, which is what you see.
