Z77 extreme 4 Security Certificate 2023

I am afraid you may be out of luck. All these security certificates, TPM 2.0 etc
are designed specifically to make older hardware obsolete. Microsoft in particular
has been pushing this issue. You can try opening a support ticket with ASRock
and asking them directly:

Unfortunately I suspect they won't be able to help you.

You should still be able to use the system with Windows 10 however your security
will be compromised. How important that is and how compromised I don't know. I
have long ago migrated all my older systems to Linux.

Good luck and I am sorry I can't give you the answer you were hoping for.

I have this :







It seems the certificates are present but not operational

That is pretty much exactly what I would expect without a BIOS update to renew
the certificate.

As for what to do about it, that depends entirely on if you use secure boot or not.
If not, you don't need to do anything, your system will continue to function as it
always has. This is the route I would take. Yes, it's less secure but I do most
of my banking and other payments etc on my phone these days so I keep security
on that tight.

Aside from that, you can wait it out. I strongly suspect that there will be third
party fixes and patches popping up as soon as this becomes an issue. Likely first
on linux then branching out to other OSes. At the end of the day, no system is
properly secure, all security implementations are flawed in some way. How secure
is secure enough for you is a personal choice based on the value of the data on
the system (banking login details etc). If you keep your important
info on a different device then you don't really need security keys.

That said, if you use your system for competitive games, some of these
will require secure boot be enabled.

I?™ll need to think about upgrading my motherboard, processor and RAM, as the motherboard uses DDR3.
But which motherboard should I go for? I need several PCI Express slots ??at least four, not counting the graphics card.
