Further more, a best practice to Enable All available instruction sets and security features. And enumerating all possible System Tables, FULL ACPI, DMI,  except ones affected by by the F variant CPU of course.

Thank you.

Hi Jose B,

Sorry for my delayed reply.

AES-NI, Hybrid CPU, Secure Memory Encryption, System Firmware Tables, actually populated... To name a few.

I have none of these things... Enabled. I know they are supported however.

How do I go about enabling them.

Thank you,

Michael

Hi Jose B,

Thank you for looking into it.

I understand this to some may look like a brief question, or set of questions.

But I know well that it reality, it isn't. I know a lot of what steps are involved, for the most part, and that the things I am asking for are not simply enabled by clicking a checkbox, it's typically a System Bring Up matter, so maybe that is the best direction for us to go in, but I will leave that up to you.

Suffice to say, these are matters and questions I have been working on for years, since taking the leap from Coffee Lake to Alder Lake shortly after release, and it's been mostly pain, but the glimpses I've had of the platform functioning as intended by Intel, have been enough for me to keep trying.

And if I knew then what I know now, I never would have gone with the F variant on the SKU, I'm not even sure why they exist in today's market, the cost savings, versus what you lose in features, is a major mismatch.

Hope to hear back from you soon.

Regards,

Michael

Hi Jose B,

I've only ever tested the one CPU, 12700KF.

It has been in two different motherboards, first an Gigabyte Z690 Aorus Master, and now an Asus ROG Z690 Strix-E.

AIDA64 really tells most of the story here, as to what is or is not enabled, and as per the case with Windows, there's some handshaking for lack of a better term, during system bring up, that when certain perquisites and methodology is followed during early UEFI config and the OS installation and Windows simply turns most all of this on for you.

With Windows 10, previous versions that would directly address the hardware, it wasn't as difficult, but with 11, which I have always been using, and HVCI being enabled by default, there's just no chance of it doing what it needs to do, in the same manner that it did before everything was heavily virtualized.

So anyway, that said, I'll include some screenshots of AIDA64's CPUID. Fairly self explanatory, a whole lot of "supported" but very few "Supported, Enabled".

Thanks,

Michael

Hello MichaelJC


Thank you for patiently waiting.


Please check the 12th Generation Intel® Core™ Processors Datasheet which includes all the explanation of processor's Security & Reliability features.


For AES-NI, usually it is enabled by default for processor, the way to enable/disable normally is in BIOS, and also we need the application that supports the AES-NI. Here you can have more information about it:

·      Intel® Advanced Encryption Standard Instructions (AES-NI)

·      AES instruction set - Wikipedia


For Secure Memory Encryption, that feature is not listed as a Security & Reliability feature for this 12700KF processor. If you are talking about the AMD Secure Memory Encryption, Intel has the Intel Total Memory Encryption and here is an article for this: https://www.intel.com/content/dam/www/central-libraries/us/en/documents/white-paper-intel-tme.pdf


For Hybrid CPU and System Firmware Tables, can you provide us with more information?
