Dear EVGA Community,
 
Thank you everyone for your patience while our team worked on the updates per Intel for the Z690 motherboards. 
These updates include the 0x129 Microcode from Intel for the Z690 series motherboards.
 
We only recommend this BIOS for the Z690 with Intel 13^th Gen. Processors.
 
The BETA BIOS can be downloaded at the links below:

• 121-AL-E699-KR - EVGA Z690 DARK K|NGP|N – v2.16
• 121-AL-E698-KR - EVGA Z690 CLASSIFIED – v2.15

 
Please take note that we do not recommend updating your BIOS if you are not running an Intel 13^th Gen. Processor.

ChrisB thank you again for getting these updates out so quickly. Today it seems Intel has finally made the "final" update to the root cause and has issued another final Microcode update 12B to fix idle elevated voltages that lead to faster than normal degradation.

Microcode and BIOS code requesting elevated core voltages which can cause Vmin shift especially during periods of idle and/or light activity. 

 

a.  Mitigation: Intel® is releasing microcode 0x12B, which encompasses 0x125 and 0x129 microcode updates, and addresses elevated voltage requests by the processor during idle and/or light activity periods.  

 
For all Intel® Core™ 13th/14th Gen desktop processor users: the 0x12B microcode update must be loaded via BIOS update and has been distributed to system and motherboard manufacturers to incorporate into their BIOS. Intel is working with its partners to encourage timely validation and rollout of the BIOS update for systems currently in service.  This process may take several weeks. 
 
I hope that EVGA will provide this HOPEFULLY final microcode update to address the issues. Thanks!

I appreciate the motherboard side coming back from the grave to make this happen. Thanks!

Doesn't the Z690 DARK support the 13900T CPU? It's not a 14th generation CPU, so why isn't this one supported either?"

Nice work but what about 14th gen 

For those wondering, I can verify that this BIOS is working with a 14900K.

There is no plan to support the Z690 chipset Motherboard and the 14th Gen. Processors due to hardware circuitry that would need to be reworked as well, to support the two generations CPUs from original design.

Hello. does my i5  13500 processor and EVGA Z690 Classy make sense for me to install a new bios?

BIOS updates are always optional ... Howerver - check the Intel statement to see that the "fix" is recommended to stop overvoltage from killing CPUs ..... FYI, Intel recently released yet another microcode update .. Intel swears yet again, the newest just released microcode fixes (released 26 September) is the real root cause 


-------------- (yet another Intel Microcode update) ------------------------------

Here we go Again, 26 September ---> yet another "root cause" found by Intel .... no really this time, they swear it fixes the real cause

Is Intel's nightmare finally over? One last patch could fix 13th-gen and 14th-gen CPU instability issues

"One might have thought all the Intel stability issue malarkey was behind us, given the official 0x129 microcode fix came out back in August. However, although this update was supposed to fix the issue, it wasn't a root cause fix.
Now, Intel's releasing a proper root cause fix for affected 13th and 14th Gen CPUs in its 0x12B microcode update. This update "addresses elevated voltage requests by the processor during idle and/or light activity periods" which have been narrowed down to being caused by a particular "clock tree circuit within the IA core". 
 
In other words, Intel's narrowed down the problem to a particular circuit within the bulk of the CPU that houses all the P- and E-Cores. The problem is, as we already knew, a Vmin one, where voltage spikes cause the minimum operating voltage to increase over time as the CPU requires more and more power to remain stable, which increases degradation."

Did you get it to work with z690 classified?

The above BIOS is only recommended for use with the below processor models on the EVGA Z690 Motherboards. 
 
If your processor is not listed below, then it is not recommended for update.
 

• i5-13600K/KF
• i7-13700K/KF
• i9-13900K/KF
• i9-13900KS

Dear Talon2020,
 
I can confirm that our team is looking into this.

Amazing! Intel has said this is the final update and no further updates after this as. THANKFULLY! Appreciate yall for looking into it.
