2020 17" Dell XPS 17 9700 (RTX2060) [10th,8C,H] + RTX 3080 @ 32Gbps-TB3 (Mantiz Saturn Pro) + Win10  

System Specs:

17" Dell XPS 17 9700

Intel Core I7-10875H

Geforce RTX 2060 Max-Q + Integrated

32GB Ram

Monitor:

Msi 34" MAG341CQ Ultrawide (3440x1440,100Hz)

BenQ RL2755 (1920x1080)

Egpu Hardware:

Mantiz Saturn Pro

Msi Geforce RTX 3080 Ventus

Included cable 

Installation Steps:

1) Installed gpu and plug in gpu

2) Install most recent drivers to get 3080 to show up (Studio drivers help with stability issues right now)

3)Disable igpu or dgpu, dgpu being disabled i found didnt reduce performance while igpu did (Did this because i had really bad stuttering while doing basically anything in windows and i found that this was the only way to fix this issue)

4) Underclock+Undervolt 3080 roughly 100Mhz core clock should help (Without this the card would crash while gaming, seems to be a driver issue)

It was quite stressful to get everything going and quite a lot of hours diagnosing the issues I was experiencing but after I got everything working I have to say I am very happy the results. It plays games beautifully and with no stuttering or glitches and having all the i/o the Saturn pro offers helps very much with the one cable setup I was going for. My only issue now that everything is setup is that the egpu is quite loud but that not being the fault of the Saturn pro, it would appear the card I got have quite a bit of coil wine making it very audible without headphones but for me that isn't the biggest issue but I thought I would mention it.

I am very unsure about my disabling the dgpu stop the stuttering, i believe it could be some sort of weird issue with having so many graphics devices at once active in a computer. I assume that most of the problem I personally experience and other with the 3080 have experience will be solved soon with drivers so I'm just happy everything is working now. On the note of getting everything working messing around with the voltages on the card in Msi afterburner I was able to get the card to the point were a -5 mhz underclock got my card stable in all of the external benchmarks and getting the memory slightly faster once the clock was finally stable. I was also achieving fairly decent gpu temps between 70-74 degrees and the cpu in the low 70s average which is quite alot better than when running it with the dgpu were it would be in the high 80s / low 90s.

Overall the egpu setup was defiantly worth the investment as I love the portability of the laptop and the convince of only having one computer as well as it having some gaming capabilities when I end up staying out and when I get home I can plug it in and have quite the spectacular gaming experience on all the games I play.
