I also run an 8920 with a 7700K chip and a professional audio interface (Mark of the Unicorn 828MK3). I assume you are using an Nvidia graphics card. I also assume that you want to do this to reduce latency and round trip latency. Go into the Control Panel and "disable" the onboard Intel audio and graphics. The biggest impact I've seen is disabling the wifi card and bluetooth. With these disabled I'm running stable with buffers down to 64 and latency below 10 msec.
"PCIe x1 or PCIe x4 Thunderbolt card which will use its own BIOS and drivers." USB 3 is not thunderbolt and vice versa. There ARE NO THUNDERBOLT PCI-E cards because thunderbolt comes from the motherboard via GPIO connection.
There is no such thing as a thunderbolt card. Therefore one cannot ADD this as a feature. Thunderbolt uses PASS THRU connection using the PCI-E bus for Power as well as a place to mount a connector. This feature cannot be added to a motherboard that does not have a THUNDERBOLT HEADER on the board. There is also a Display port Wrap thru cable required.
The TBAIC card has 3 parts. The card, the Display port Wrap thru, and the Thunderbolt header cable.
NONE of these parts are OPTIONAL.
Thunderbolt isn't really and add in card. There are no thunderbolt upgrades. They are also not universal aka Dell Card is for Dell ASUS card is for ASUS. The Thunderbolt header goes to a header on the motherboard.
They use the card to hold a bracket but there is no PCI-E specification for thunderbolt card because it does not exist.
A Dell card not one from ASUS. This is not a card that just requires PCI-E bus to EXPAND your system to Thunderbolt. Therefore it is NOT an expansion card but rather a bracket to hold the thunderbolt port and provide power to the Thunderbolt Transceiver. The card is essentially a mounting bracket for the thunderbolt port. "Asus is about to release a new Thunderbolt3 adapter card " This will not work in a DELL. Nor will this be an upgrade VIA PCI-E.
Its NOT an expansion card that will go into any machine. And such cards are not interchangeable between vendors.
Thunderbolt goes to the card and Display port wraps into the card via cables. Without these cables and POWER from the PCI-E bus these cards do not work and therefore are not interchangeable or applicable to ANY other system. You can't use the ASUS card in a dell and you cant use the DELL card in an ASUS for example.
People see this card and think that if they have a PCI-E bus they can upgrade to thunderbolt. This is not the case.
as stated but not clear
if you must have thunderbolt, (must you?) then buy a PC that supports it.
there is no other answer, ok?
is this really needed and why, name a usage ok?
The Thunderbolt technology can transfer data at the rate of 10Gbps.
Speedsteps post was clear, did you read that?
it also explains why you can't find it. (it's not add-in technology, like USB is and PCI-express is.
oK? It's DESIGN IN Tech.
The Intel Graphics is integrated into the CPU so there is no feature to disable.
Thunderbolt support in the XPS SE 8920 bios is never an option EVER because thunderbolt is a CHIPSET and Controller option not a bios feature.
What is being asked for is never an option ever on any pc.
Which PCIe Thunderbolt cards (None Exist)
there is no such thing as a PCIe Thunderbolt card.
The Thunderbolt card for specific Dell Models and the ASUS boards uses PCI-E as a mounting method.
The actual Thunderbolt portion comes from a header on the motherboard and also requires a display port wrap thru cable.
USB C IS NOT THUNDERBOLT3 They use the same connector but thats all.
Thunderbolt is the brand name of a hardware interface standard developed by Intel (in collaboration with Apple) that allows the connection of external peripherals to a computer. Thunderbolt 1 and 2 use the same connector as Mini DisplayPort (MDP), whereas Thunderbolt 3 uses USB-C connector. Intel offers a single port (JHL7340) and double port (JHL7540) version of this host controller and a peripheral controller supporting two Thunderbolt 3 ports (JHL7440).
