Z790 - New BIOS 2703 --- CPU throttling to 800MHz problem

[Wesley1]

Has anyone tested it yet?
Is it good?

Did Asus fix Windows Power profiles? I mean extreme CPU throttling issue in Windows 10 after C1E state are enforced.

Can you please post a copy of your BIOS in .txt format?

It's not possible

I thought it was the IA CEP option and the SA CEP option which I have both disabled, This fixed this issue in previous bios's but not the 4001Bios for Z690 however I have not tried Enhanced C States,I am not even sure that setting exist in this bios I would have to take a look and see if it's there, I do from memory recall seeing a C states option but can't remember if Enhanced C states is available.

But I thought disabling C states would keep the clocks pinned at full boost anyway ie 5.7ghz for me? 

I will take a look and see what I can find thanks.

EDIT...

I just checked and there is no "Enhanced C States" in my bios" I have just tried disable "C States"" and it's exactly the same behaviour, Clocks all over the place even with CEP and C States disabled.

You could check if C1E is enabled on your motherboard with ThrottleStop application.

On earlier BIOS version 2602 Beta and 2703 it allowed to disable C1E from Windows, just uncheck C1E and press save.
But it only works for current Windows session and will reset to default after reboot. So the process needs to be repeated.
Either way it it good tool to check and troubleshoot PC.

HWInfo64 also shows the status of C1E in summary (not the sensors) window. But it does not allow to change it.

I'll give that a go and see what happens but it's looking like this bios is afoot somewhere, I know they have locked it down but it should not affect the boost behaviour of the CPU and it certainly should not be fluctuating like it is even when on "High Performance" Even the Vcore is dropping to 0.6v when on "High Performance" power plan, That should not be happening.

I have those same settings Disabled and more.

In the corner I notice your Freq. even shows 5700 MHz. Mine shows 3200.

Well, it used to work normally with High Performance power profile with default settings.

Which were:

RingDownBin on Auto - set to Enabled.
SpeedStep - set Enabled
SpeedShift - set Enabled
C-states on Auto - set to Enabled ???

C1E on Auto - set to Disabled

The first four you don't really want to disable, since it allows CPU to reduce power consumption when it does not needed so much power, e.g when you switch to Balanced Power profile.
Allows for better CPU temperatures and CPU lifespan.

Can do it later when near bench. See my original post - those are the only parameters changed.

Not a stretch by any means to think that the new microcode would change boost behaviour.

Only have the Apex Encore here.
