Hey guys,

my new RTX 3080 Gaming Box arrived yesterday, replaced my "old" RTX 2080 Ti Gaming Box and I like to share some details with you.

 

System specs + eGPU hardware + Hardware pictures

I used my Mac mini (latest Intel-based Mac mini from 2018, maxed out to 64GB RAM) w/Win10 20H2 (latest build) running at Bootcamp partition to test the new monster.

I also took a chance and built a soundproof case that allows me to banish the Gaming Box from my desk. I added some insulation/acoustic foam inside and installed a Noctua NF-P14s redux-900 fan including a power supply with adjustable voltage. This guy is really quiet, even at 10V (out of a maximum of 12V, what I never use) it's barely audible. I left a vent open at the back of the case where the cold room air is sucked in and the front fan blows the warm air out. Works better than expected!

I'm not much of a craftsman, but this was fun to make and I think it turned out pretty well - not to mention it serves its purpose just fine... 

Here are some pictures of my build:

It has to be said that the Gaming Box RTX 3080 itself is really very quiet when directly compared to the RTX 2080 Ti, even under full load the fans never turn up as loud as they did in the old box before. This might be due to the fact that the cooling technology has been improved or the GPU does not really reach the 100% load, maybe TB3 bottleneck? Any ideas? --> @itsage already confirmed that the RTX 3080 runs a few degrees cooler than RTX 2080 Ti  and therefore produces less noise overall.

Together with my housing the setup is barely hearable under full load (36db at my sitting position and around 40db directly measured next to the Box (front)). That's not much louder than normal background noise, so quite good I think!

 

Installation steps:

The unboxing / connecting was very straight forward and plug & play because of my existing setup with the previous model, same configuration and drivers used. I just unpack the new Box, connected power cable and my existing DP cable and a longer TB3 cable (previously used), because the provided TB3 cable is much to short for off desk use.

Heres in detail what I did:

- Having an installed Win10 20H2 (latest build) with latest NVIDIA drivers for RTX 3080 installed, too.

- Booting into Win10 by holding option key during startup, select bootcamp partition, log into Windows, wait about 10 seconds and then hot plug the eGPU. Pray that there's no blue screen appearing (50/50 chance), otherwise reboot again (don't forget to switch eGPU off before) --> Btw, does anyone know a better way to deal with that?

- The eGPU gets recognized and produces output on DP, then I switch to display settings and select exclusive monitor output to second screen (external monitor only). This display selection has to be done only once (first connection). Have to mention, that I have another connection to the same display via USB-C to DP-Port adapter (iGPU in Mac mini) to use it in MacOS, this adapter is used during boot process and at login screen (and therefore Windows shows two monitors).

 

Benchmarks + Comments:

Did some benchmarking with the "old" RTX 2080Ti and the new RTX 3080 to compare performance.

The Bootcamp Win10 20H2 (latest build) runs at 4K/2160p resolution with 125% DPI scaling, latest NVIDIA drivers installed, V-SYNC remained switched on.

First I mention the used Benchmark tool and the settings/preset, second the score points and/or FPS for the RTX 3080, last the performance gain in percent compared to the 2080Ti (used the score for calculation, if not present I took FPS value).

Have no screenshots for that, nevertheless hope you believe me. Smile

Can create some, if you wish.

Awesome results, great to see the 3080 giving a big boost over the 2080ti.

 

How did you buy one? I wasn't aware the gaming box was out yet? Can't find it for sale or listed anywhere.

@roedi78, Have you tried cold boot with the eGPU connected and monitor only connected to the eGPU? OS switching can be accomplished through Startup Disk in macOS and Boot Camp Utility in Windows.

@lycid, I ordered mine from Cyberport online store in Germany. Seems that they still have some units in stock at the moment. I preordered weeks ago and now they shipped right before Christmas. Smile

 

Hey @itsage, thanks for your suggestion. The problem is that in macOS the Bootcamp partition is not listed in Startup Disk, just the macOS partition. Therefore I can't preselect Bootcamp for next boot on macOS side. What I tried is cold boot with the eGPU connected + monitor only connected to the eGPU and then select Bootcamp partition in "blind flight" with holding down option key, wait 15 secs, press right arrow key (to switch to Win10 partition icon) and press Enter. This didn't work, the eGPU wasn't comming up.

@roedi78, hi, got the same confit (Mac mini 2018 and gaming box rtx 3080)

 

The leds on mine are running when plugged after booting in OS X, but not in bootcamp.

Updated to latest nvidia drivers, In bootcamp however I can see the rtx 3080 recognized in device manager but the hdmi output of the gaming box does not display anythin. (And leds are not flashing, although it’s obviously running and noisy..)

 

When trying to boot with the egpu plugged in, I just get endless blue windows logo flicks.

So this technique of hot plugging after 10 secs in boot camp worked for you? Any luck finding anything better?

 

thank you

 

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

@wajaja, yes, I still use the hot plugging workaround approx. 10 secs after logging in into Windows. I have a 50/50 chance of working Gaming Box RTX 3080 vs. BSOD.

Still found no other (better) solutions.

In addition / correction to my own post I have some news regarding the "suboptimal" booting procedure.

After installing the latest macOS 11.3 Beta and the latest Win 10 20H2 Build 19042.844 the issues are completely gone! Now I can boot the Mac mini with connected eGPU and it is recognized and fully working, I don't have to hot plug the eGPU anymore. 

I still use two connections to the monitor:

(1) DP1-Port <--> USB-C (Mac mini), for using the Mac mini with macOS (iGPU) and at boot time for having display output while switching between macOS and Bootcamp (holding Option key)

(2) DP2-Port <--> RTX 3080 Gaming Box, for use in Bootcamp

Once I configured the Windows screen settings to use only monitor 2 (I only have one monitor, but two connections to it, so DP2 = eGPU), it displays the login screen directly via eGPU, no further switching necessary.

 

So after all I'm fully happy with my setup!
