Update 9/27: The undervolt stopped working for me all of a sudden. However, disabling integrated graphics seems to fix things for me without having to bother with undervolting/underclocking....

Update 9/25: The standard undervolting solution that everyone is talking about fixed it. 

I undervolted properly after watching a youtube video and it fixed it. I didn't know I had to actually open the voltage curve editor. Here's what it looks like https://imgur.com/a/jV7s2Lg  

Now I'm at ~13k for graphics score, up from 11k, and my cpu score is normal now.  Most importantly I'm not stuttering or throttling anymore. It's still quite a bit lower than the standard 14k egpu performance or the 17-18k desktop performance but hopefully Nvidia fixes everything with a driver soon.

 

See this build - https://egpu.io/forums/builds/2020-17-dell-xps-17-9700-gtx-1650ti-10750h-6c-rtx-3080-32gbps-tb3-mantiz-saturn-pro-ii-win10yo2u/#post-86796

Ran a 3080 FE in a Saturn Pro II on my XPS 17 with disappointing results. 

Specs:

Dell XPS 17 9700 (10750H, 1650Ti, 32GB, 512GB PM981a + 2TB 970 evo plus)

Mantiz Saturn Pro II

RTX 3080 FE

Aorus 1070 Box

AW2518HF 1080p @ 240hz,


Timespy:

With 3080 in  Mantiz Saturn Pro II :

Major stuttering throughout benchmark. Otherwise scores seem comparable to a 2080 super laptop

Notice the low CPU scores, esp compared to the 2 configs below.

https://www.3dmark.com/spy/14016599  (11236)

https://www.3dmark.com/spy/14015664  (11507)

With Aorus 1070 box:

Within bounds of egpu 1070 performance - no stuttering

https://www.3dmark.com/spy/14035736  (4839)

With dGPU 1650Ti:

Avg performance for 1650 Ti - no stuttering

https://www.3dmark.com/spy/14016997  (3655)


3dMark PCI-E

2.3 GB/s - https://www.3dmark.com/3dm/50677920?


A lot of stuttering in Flight Sim on Ultra (fluctuated between 10-25 fps constantly)

FPS was capped at 60 in World of Tanks  even with forced vsync off, 240 hz setting. Game was smooth otherwise.

Crysis Remastered ran ~ 20-30 fps on Can It Run Crysis Mode, 30 FPS on High, 60 FPS on Low. No stuttering.

The performance here is pretty underwhelming - These FPS are below what I would have expected even @ 4K. I'm only running on 1080p


I think the issue is either the gpu, enclosure or drivers since I have no stuttering issues with my 1650 Ti or my Aorus box. Will be testing with a friend's 2080 Ti this weekend to see if its the GPU or the Enclosure.

Hopefully the issue is drivers though it seems like other people have posted 14k Timespy scores with their 3080 eGPUs.

Any thoughts?

I read a post about Dell not cooling their PCH and added a ram heatsink (thermal pad + copper heatsink) to it. Unfortunately did not really affect the performance. https://www.3dmark.com/3dm/50680265?

Sry no plan but shot up in the air;

Your SSD and PCH are very close to each other and if your laptop gets fiery still try to cool the base plate with a fan while the benchmark is running?
With Trottelstop I had to recognize that there are mechanisms that are not obvious; CPU already under voltage and what is your bios version?

have you uninstalled Dell's power management?

There is also a similar and circumcising madness from Intel that has to wake up if you want to get everything out of your laptop ...

the more you connect the TB3 to a data-heavy GPU, you should also be more prone to bottlenecks so that your aurus 1070 BOX might just be enough ...

I hope not, but maybe the Founders Edition also has an influence on it.

@w7_basel, Let me try throttlestop later tonight. I had flashed the latest Dell bios (1.3.2), haven't turned off power management. I had ordered my xps config to minimize chances of throttling (large chasis, vapor chamber, not i9) :/

 

I might try a Razer Core X next week to see if theres a difference as well.

@yo2u, I was getting stuttering with a Razer Core X Chroma in my setup also in 3D Mark. Also could have been a PCH issue as it doesn’t have a heat sink but unsure.

@imconfused, Bummer 🙁 I hope the 2080 Ti works better for me then. I did end up adding a copper ram/ssd heatsink with thermal padding on both sides - didn't seem to help

A couple of updates:

1. ThrottleStop did not help even though the CPU was definitely throttling with the 3080 (but not the other gpus)

2. PCH was not overheating based on sensor readings

3. Underclocking did not fix it

4. Undervolting however did 😉 Hopefully this is a driver fix that Nvidia can patch soon.

How are your results now that its fixed?

 

I've got a similar setup and I've not seen many results with the 3080 on a laptop that doesn't run the tb3 connection direct to CPU. Wondering if its worth switching over from my 2080ti on my i7 Razer Blade 15 2019. Would be a shame to have to get a new laptop so soon if I actually want to see any improvements on a 3080 🙁

@lycid, if you are looking to get a new laptop I'd hold out a few more weeks/months for a Tiger Lake with TB4, or even an AMD powered with thunderbolt which are starting to come out. I've got Ice Lake and the direct TB3 connections doesn't seem to be making a huge difference.

Well, was more looking to not get a new laptop! Hopefully the 3080 can provide good performance from an i7 8750H, but if it can't, then I'll be forced to upgrade sooner than I'd like if I want to use the 3080.
