ASUS ROG Unveils Beta BIOS for 14th Gen Non-K Processors to Enhance Performance on Intel® 600/700 Series

 

TAIPEI, Taiwan, February 16, 2024 – ASUS unveils Beta BIOS for Intel® 600/700 Series motherboards, boosting CPU performance to higher level for Intel 14th Gen Non-K Series Processors. 

Update the Intel microcode to version 0x123, allowing for disabling the Current Excursion Protection (CEP)1 for improved performance2 on Intel 14th Gen non-K series processors. 

The Beta BIOS for ASUS Z790 series motherboards now are available. B760 & 600 series will be updated shortly!  

1 CEP is a processor integrated detector that senses when the Processor load current exceeds a preset threshold by monitoring for a Processor power domain voltage droop at the Processor power domain IMVPVR sense point.  

Disable CEP may increase performance in MT workloads on systems with a Loadline (LL) lower than 1.1 mOhm.  

Disabling CEP for performance enhancement may lead to increased power consumption and temperature. 

2Ensure adequate CPU cooling or use a higher-spec cooling solution.

Maybe a little early to say but has anyone tested the new bios yet? 

I see two new bios versions available on the Asus Apex Encore website, 0904 and 1001. Unsure what bios to choose now.

The 2001 beta BIOS release notes say that disabling CEP improves performance for non-K CPUs, yet the tests posted here show a 14900KF? I'm so confused. Should we flash 1904 or 2001? Which is better?

Is there any benefit of disabling this CEP function on K series for example on 13900KS? Default is Auto - which means Enabled or Disabled by default?

It might be premature to ask, but has anyone tried out the latest BIOS yet? I've noticed two new BIOS versions on the Asus Apex Encore website, 0904 and 1001. Not sure which BIOS to go with at the moment.

So CEP is just for undervolting?

I still don't fully understand the benefit of disabling it on a K/KF processor. The tests posted here show a performance gain on a KF processor but the BIOS release notes say it's for non-K processors?

The BIOS contains a new microcode, for which is applicable to both types of CPU.

CEP is disabled by default on K CPUs on Z Series motherboards, the uplift comes from elsewhere.

Thank you, this clarifies everything.
