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

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.

It's possible that the AI Optimized is picking up on the thermal limits and throttling it.

I set it to asus profile and sync all core to 57 or 58 mce enabled,  c1e disable,  tvb disable, ring down disable,  do i need to set ac dc manually?

Can anyone confirm that rkisch BIOS settings are working?

I copied all of your settings to my bios, the result was horrible,  p5.2 e4.2 during r23, p5.4 e 4.4 at idle 

R23 score 36000 

I can't believe it

I think it's fair to say at this point with so many complaints that there is something wrong with 1801.

Long time 14900KF and Asus ROG Strix Z690 Gaming A user here since day 1.

I have been using BIOS 2802 for a long time now and had 0 issues but I thought I'd give the new 4001 BIOS a whirl and can confirm what users are saying here.

While I am not seeing much difference in benchmarks ie Cinebench R23 and CPUz or Geekbench, Even though Geekbench multicore is down slightly I can confirm my clocks are all over the place with 2-4 random cores constantly dropping to 800mhz even with "High Performance or Ultimate power" Plans.

And yes it is affecting games and latency also and here is how you can easily test it with the new Indiana Jones and the great circle.

This game has built in performance metrics in a traffic like system scenario ie Good latency response the CPU busy times are "Green" not so good and the colour changes to "Amber or Orange" and crap it changes to "RED"

This new BIOS with the new enforced C1E is always Red in Indiana Jones indicating poor response from the CPU, Make of that what you will but it is most certainly affecting games and latency and quite frankly this just should not happen with a high end CPU.

I am not blaming Asus as this is Intel who have enforced this with the new Microcode however in another manner this is now restricting me from updating my BIOS with all the latest fixes since 2802, Imo what is wrong with Asus not allowing this behaviour for Advanced users in the BIOS when that is what the "Asus Advance OC Profile" is supposed to be for?

This is what happens when I set my power plan to "High Performance" Clocks are all over the place with the 8 P cores not even being able to sustain the base clock spec speed nevermind the 5.7ghz boost speed and I am seeing this behaviour in gaming also across multiple titles, As far as I am concerned this is not acceptable after all this is a flagship gaming CPU, What is the point of pairing high end components like an RTX 4090 and high speed RAM with a CPU that is being crippled because of latency and causing a bottleneck to the RAM, GPU and storage thanks to Intel locking it down.

After some backlash, Asus responded with releasing new BIOS 2801 in which you can disable C1E energy saving feature.

The option in BIOS is named Enhanced C-states [Disabled], you need to set it to disable state.

BIOS 2801 still has some problems with CPU clock fluctuating between base and turbo frequencies, but this is P-state range and should not add much (if any) latency under load conditions, including gaming.

The enforced C1E in previous BIOSes is clearly connected to Intel's Vmin Shift issue, and now Asus BIOS warns you that if you disable C1E, it will accelerate silicon aging (a.k.a. Intel's Vmin Shift issue). But we haven't bought CPUs for z790 platform to run it at LFM (Low Frequency Mode) frequency.

I don't experience any fluctuation at all.

Good for you, about 10 other users tend to disagree.

Same ucode with the same firmware, not doing anything, in particular, other than disabling power saving features outlined in my post...

If you're still experiencing issues on 2801 / 1801, best to contact service - as on the Apex Encore it appears to function perfectly well.
