Asus P6t VT-D support

[gabklein]

Hello,

If you want to be able to boot in Windows 10 with Vt-d enabled, try this in BIOS:

- Vt-d: [Enabled]
- Advanced menu / USB 2.0 Controller: [Disabled]

Yes... this works for me and my P6T Deluxe (and USB ports still work as USB 2.0 speed !).

Hello,

I registered in this board just to reply to this, it "works" (Windows 11 boots normally) however the USB does get downgraded to 1.0.. triple-checked with my webcam, it gets very slow when disabling USB 2.0, so for me it is unusable.

But anyways thanks for this, I can't believe I'm not the only one rocking this old motherboard, DDR3 and a i7-930 CPU from 2010 

By the way, here's a tip for us with old PCs: enabling Windows Sandbox also enables Hypervisor and slows down the PC

I found an Alienware with this motherboard in the garbage 2 years ago, on the pavement... Just had to add RAM, an SSD and a graphic card.
I'm still using it as my main PC and even replaced the original i7 with a used W3680 Xeon, very easily found for 40$ on eBay.
I installed Windows 11, too.

USB 2.0 is disabled in my BIOS.
I just tested USB ports speeds again for you: both with the internal and rear panel connections, files are copied from a SATA SSD to an USB connected SSD at 215 Mb/s.

USB 1.0 speed is 11 Mb/s max, and USB2 is 480 Mb/s max.
So my ports are definitely USB 2.0.

By the way, even with 11 Mb/s ports, it shouldn't get "very slow" except maybe if you use 4k video or 1980p/60 fps ?

Maybe you should try other USB ports with your webcam ?

I just made a couple of tests, and I can confirm the USB ports does get downgraded from USB2 to USB1.
I plugged my webcam in a rear USB port (it was plugged in my monitor), and the slowness continued.

I also tested speed by copying files from an external USB HDD to my internal SSD, speed went down from 33MB/s to 900KB/s.. so I can confirm the USB ports get downgraded to USB1.

My motherboard is P6TD (Deluxe), not P6T, maybe that's the reason? Maybe they fixed this USB2 toggle in BIOS.

PS: I checked the motherboard manual, all ports (front and rear) are USB2, there are no USB1 ports.

But anyways, I'm fine living without VT-d, it is just a faster virtualization for I/O.
