This is wonderful. Now you have:
The 4GB memory I found is 2666MHz, BIOS? down-locked them all to 2666Mhz,Was it necessary to down-clock the memory to 2666MHz?
** Experiment Update #3 **
AppleVTD Side-Effects and Mitigation Strategies
To extend Thunderbolt compatibility to Antelope Audio, Apple TB-to-Gigabit Ethernet Adapter, and some other devices, we have found that enabling VT-d is the key.
This can be done on any Intel-based Hackintosh and does not require any special or modified BIOS. To enable VT-d, we need to do the following:
- Enable VT-d in BIOS
- In OpenCore config.plist, uncheck DisableIoMapper (in the Kernel Quirks section)
- In OpenCore config.plist, remove "dart=0" from Boot-Args if present (in the NVRAM section)
- After rebooting, run IORegistryExplorer to see whether a new device named AppleVTD appears near the top of the list. This confirms that VT-d is enabled.
As you can see, the number and capacity of memory DIMMs make a difference.
On my Asus X99 Deluxe II, VT-D is located here:Yep both ports work. The ASUS Sage/10G has a Intel X550-AT2 so I modified the EEPROM to work with SmallTree drivers
BIOS changes: None - Can't seem to find VT-D in the ASUS X299 BIOS
config.plist changes: DisableIoMapper (false)
- AppleVTD Enabled
- 4 DIMMS (4 x 16GB @ 3200)
- Broadcom BCM943602CDP (Wifi + Bluetooth work)
- Both onboard Ethernet ports work - Intel X550-AT2 with SmallTree8259x.kext
- No Thunderbolt card (Will be getting a Titan Ridge to flash)
