XPS Desktops

[RoccoP326]

I have a Dell XPS 8950 Desktop and need to enable Intel SGX (Software Guard Extensions) in the BIOS (Set to Software Controlled). Does anyone know how to do this? Is it not needed with Windows 11. I have an Intel i9-12900 CPU. I am trying to play 4K disk using a drive capable of playing 4K.

Any help is appreciated.

Intel deprecated SGX for Intel12th Generation i9 12900 Intel CPU

Without SGX, you will be unable to play UHD 4K Blu-ray Discs (at least legitimately using e.g. PowerDVD Ultra).

possibly why it’s not an option in the BIOS for that machine.

It is a shame.  I had hopes that 4k playback support could be built into a high end graphics card but I am unaware if that exists.  If any one has any way of making this work please share.

Hi I have the same issue with an XPS 8940. My intel I9-11900K does not have the SGX feature. Went into the bios and SGX is not listed, so can not enable obviously. Can we install SGX though? This is something I am not sure about. Wanted to purchase one of Pioneer's 4k external drives but read that it needs this SGX thing. Very disappointing, after spending this much money on a computer, one can not even watch a stupid 4k blu ray. Will try with a cheaper Chinese blu ray drive. If anyone can inform if we can install this SGX thing or have a solution to this issue , thanks in advance.

Just read that in Intell 11 and 12 systems , SGX is not supported anymore. Insane.

And no, the i9-11900K doesn't support SGX so it can't be installed.

You'd have to downgrade PC to a 10th Gen CPU that still supported SGX, but that depends on if the XPS 8940 can even support any 10th Gen CPUs. And that would be a waste of your i9-11900K CPU.

Even Cyberlink  has given up supporting 4K Blu-Ray discs...

You may still be able to watch 4K Blu-Ray discs with a player connected directly to a 4K TV....

It is amazing that another solution does not exist.  I’m still have hope that someone will come up with a software add-in or a piece of hardware that can plug in.  Perhaps there could be a graphics card that would have SGX support built in.  Why would Intel drop this and not offer some other option.  Let me know if you find another solution.  If I find one I will reply to this thread and you.

If Cyberlink has given up trying to support 4K discs on PCs with an 11th or 12th Gen CPU, the outlook doesn't look good.

Latest Cyberlink software is PowerDVD 21, which requires "Intel 7th generation and until Intel 10th generation Core i processors that include the Intel Software Guard Extensions (Intel SGX) technology".

Serious new security issues were constantly being found in SGX technology which is why Intel abandoned it.  So somebody would have to (a) license SGX tech from Intel, assuming Intel would license it out, and (b) fix all those security holes that were just too much for a company as big as Intel to handle.

The tech has moved on...

I’ve now heard of other non SGX solutions that may work to play 4k disks on selected 4k drives.
