Yep Speakers, Mic, USB ports and webcam all work. 4k 60hz too. I went with a Streacom DA2 (sleek af) Ryzen 3600x, can't remember the mobo name but it's in this thread (the ASrock AMD itx tb3 one) 16gb ddr4 3200 ram, Noctua cpu cooler, Noctua case fan and Asus (stock blower which works well for small form factor) Radeon 5700xt 8GB. Haven't tried MacOS yet but I will when I next get some time off work. Went with the 5700xt for macOS compatability and at overclockers it worked out at £300 with a cash back offer ( £360 retail then £60 off for leaving a review). I was between that and a 1080ti (last Nvidia card to 'work' with MacOS) but the radeon matches it and even beats it in a few games. Running Apex Legends 1440p 144hz on my second monitor and 4k 60 high settings for single player games ( on the LG monitor with it's unbeatable 500nit brightness, panel uniformity and dci-p3 colours :D)

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

holy cow! Thats better than expected. I was going to be ok with Speakers and camera not working as I tend to use headphones and have no use for the camera in W10. I'll be super interested to hear how it works out if you Hack it, from what I have been reading TB3 support can be flakey so I dont hold up much hope, but I'm defo gain to give it a bash once my final parts eventually arrive...

@eightarmedpet I will say this I have tested the 5k monitor through my promise 2 pegasus 2 raid chasis via daisy change with a thunderbolt 2 to thunderbolt 3 adapter, the weird thing to my surprice is that it WORKED. but only at 2560x1440 resolution.

pretty sure its the same deal with the trash can mac pro on thunderbolt 2. so the monitor can run at thunderbolt 2 speeds you just won't get 5k res. This was in mac os maybe better in windows? not sure.

I just finished building a DAN Case A4 with the Phantom Gaming Mini-ITX AM4 motherboard. The only problem I have is that the SB cooling fan goes at 5400 rpm and it's super whiny. I'm working with a Noctua L9i + Ryzen 3700x. The SB is always at 55C no matter what I do (Played with the fan curves that is). Let me know what you've done to cool that beast down please! Smile

@teltersat2 the fans on these x570 boards are awful! It really annoyed me and after reading up on it I decided it was safe to adjust the fan curve so it didn't kick in until it hit 70. At idle my machine is very nearly silent, as soon as I game the Vega jet turbine cranks up and drowns out any other noise, including my neighbours tv, so I can't hear the mobo fan anymore.

 

@guideofgalaxy thats really interesting! Are you 100% sure its 1440? Have you used Easyres?

 

I mentioned it in a different thread I think but I have my 5K working in Windows @4k being powered by the Vega due to the DP in and TB3 out, its a fantastic little set up, keep meaning to write a SFFPC vs eGPU post because I dont feel its as clear cut as people make out (the claims of being able to build a PC for much cheaper with much better performance are only kinda true - the type of person who has a MacBook and wants an egpu isn't the type of person who would be happy with a big plastic beige tower covered in RGB lights so the SFFPC will cost more than people claim/expect. - Example: I'm using a Louque ghost case and you are using a Dan case, both the same price as an egpu enclosure which comes with PSU).

just curious would on of those splitters work?

effectively giving you 2 display ports from you graphics card and going into one?

maybe this will give you 5k res?

@guideofgalaxy,  No. That adapter is a DisplayPort 1.2 MST Hub. The input is a single DisplayPort 1.2 signal. Most GPUs have at least two DisplayPort outputs, so I don't see how a MST Hub will help.

5K on the LG UltraFine 5K requires two DisplayPort 1.2 signals. The LG UltraFine 5K requires that those signals come from Thunderbolt 3 so you need a GC-ALPINE RIDGE or GC-TITAN RIDGE or a motherboard with Thunderbolt controller and two DisplayPort inputs.

There are other displays that can do 5K or 6K or 8K without Thunderbolt and without two DisplayPort connections.

 

Mac mini (2018), Mac Pro (Early 2008), GA-Z170X-Gaming 7, Sapphire Pulse Radeon RX 580 8GB GDDR5, Radeon Pro W5700, Sonnet Echo Express III-D, Trebleet Thunderbolt 3 to NVMe M.2 case

@joevt,  the point of it isn't for the graphics cards sack its for the 1 display port, on the board that is the intake display port for the thunderbolt port.

there are 1.4 version of this adapter but effectively you are pluging 2 display port cables from your graphics card into the adapter and then plugging in the adapter into the motherboard inbound display port, effectively giving you 2 display port signals for thunderbolt output.

 

But I don't think these adapters work in reverse. So if any one has one of these and tries it let me know if it does anything for you.

But by rights, it should work with a single display port 1.4 its support to have enough brandwidth to support 8k displays so it should run at 5k.

@itsage,  if you can connect a thunderbolt eGPU to itx board you could then buy one of those thunderbolt bridge pcie cards, and look the egpu into that giving you 2 display ports this could work maybe.. has any one tried it?

@guideofgalaxy,  Yes it should work with a GC-ALPINE-RIDGE installed in the PCIe slot of the motherboard. Built-in Thunderbolt 3 would host the eGPU and AIC would use dual DP from eGPU to produce Thunderbolt 3 monitor output.
