Ah wait, all the older BIOS are available for download, I'm going to try 2.04
 
edit: just went through the 2.04 thread. I assumed things would just work. I guess that is not the case with BIOS updates unfortunately. 2.04 allows successful POST and loads into BIOS. I will try 1.15 since someone recommended that one in that thread for alder lake CPU's.

Solaris17
CPU: 13900k
Mobo: z690 KP

Flash to 2.05

Bitlocker trip (expected)
Windows needs activation now (just like 2.04)
CPU still will not boost with C states on auto (currently correcting it by setting to "Enabled" then setting "Enhanced C1 State" to "Disabled")

Which OS version and build?

A couple bug fixes.
 
BIOS 2.05 (E699 DARK K|NGP|N / E698 Classified)

• Fix ring control issue.
• Fix CPU may request more voltage for vcore. 

 

• E-cores are still capped at 43x. BIOS set to 47x is ignored.
• Also, P-cores are not holding under load. They randomly drop to less than 56x all core. They are not fixed at 56x as they should be. They should not drop below 56x as they are doing.
• BCLK spread spectrum is still too loose and allows core clocks to dip slightly below 100.00 * multiplier. (Please give us access to spread spectrum so we can set it to 0% if we want to.)
• My memory is unbootable with settings that worked on 2.03 and 2.04. I am booting stock 4800 JEDEC for the screenshot.

Windows 11 Pro. Still messed up and unusable. Only the Ring ratio is fixed.

Going back to 2.03 Beta BIOS at this time. I can't use 2.05 due to the malfunction. The most recent BIOS version for 13900K with the correct functionality for me is and 2.03.
 
I am using ELEET to show what my E-cores are set at in the BIOS. Check HWINFO64 to see what they are actually doing.

• Set Intel Adaptive Boost Technology to Disabled
• Set Thermal Velocity Boost (TVB) to Disabled
• Set Enhanced TVB to Disabled.

In the Advanced - CPU Configuration menu please try the following:

• Set Intel Adaptive Boost Technology to Disabled
• Set Thermal Velocity Boost (TVB) to Disabled
• Set Enhanced TVB to Disabled.

 
For the record, Spread Spectrum for BCLK is already disabled (or set to 0%, in the way you described it), and no additional memory changes were made between 2.04 and 2.05.

No additional memory changes… Dammit, I guess I’m staying on 2.03 for the rest of my time with my board. On 2.03 I can do 7400, but on 2.04 I legit couldn’t get anything going. It’s like 2.04 exacerbates how bad my 13700K’s IMC is.

Did you try disabling C-states? I could not POST with my tried and true memory overclock settings with C-states on the default "Auto" setting. So, the memory issue is solved for me, but the P-core and E-core clock capping is unresolved. It's weird that the BIOS settings for P-cores and E-cores is being ignored. The behavior is exactly the same as what I had with the ring ratio setting being ignored on 2.04. Seems like 2.05 moved that problem from the ring to the CPU cores.
 
All of the BIOS settings for TVB garbage are set to disabled.

Z690 Classified does not booting with G.Skill Flare X5 Samsung B-die 
with one stick in any slot motherboard wont boot - 53/54 loop
with two sticks it will boot, but will see only half 
Memory works perfectly with other boards - Msi Z690 Force and Asus Z690-F Strix

I think just flash back to 2.03, I don’t think 2.04/2.05 play nice with everyone’s individual board samples, memory ICs and CPU IMCs. That’s the only logical deduction. For some they run amazingly well, and for others, they compromise the memory subsystem.

Yeah, totally. 2.04 would have actually been acceptable for me if not for the ring clock issue. Memory overclocking was fantastic for me (Hynix M-die). I am going to revisit 2.05 when my TG Delta A-die kit arrives. If it works great I will keep the A-die. If it doesn't I will probably send it back for a refund. I am wondering if it is so optimized for A-die that it's just not any good for anything else.
