2021 17" Dell Precision 7760 (RTXA4000) [11th,8C,H] + RX 6800 XT @ 64Gbps-M.2 (ADT-Link R43SG 4.0) + Win11
Hi, it's me again. I am back with new hardwares as promised!
I've just got a Dell Precision 7760, and it is my ideal laptop for EGPU setup, (or if you want, you can go for the 15inch Dell Precision 7560, but the thermal is a issue for CPU) It had a quick access slot at the back of the laptop, which can host a M.2 ssd, which unsurprisingly can host the ADT-Link R43SG 4.0 again.
(the screen on this device is nice as well, a 4k120Hz display with 100%ARGB and 500nit brightness)
The system info:
128GBs of Kingston Fury Impact DDR4 3200mHz@cl20 (overkill maybe?)
dGPU:RTX A4000 (wrong choice for EGPU setup)
The rest of the system is still the same compared to my old one, which you can find here: https://egpu.io/forums/builds/2021-15-razer-blade-advanced-rtx3080-11th8ch-rtx-3080-ti-64gbps-m-2-pcie4-0x4-adt-link-r43sg4-0-win10-win11/

The 6800xt can be bottlenecked by the thunderbolt connection severely. I've done testing on my old Razer laptop, (well, an 11th gen i9 is technically not old but...)
this is the setup, I've used atx power the GPU.
The connection is rather simple, just screw the link to the laptop
Now just do what a regular PC GPU installation on the adaptor, and follow the guide of ADT so your GPU won't fall off.
When you turn on the laptop, be aware of the light on the adaptor,
If the first two went on, that means the GPU is connected to the laptop.
Now you need to do is the check if the GPU showed up on the device manager. （restart if it didn't show up）
regular 3dmark test, the first is 6800xt with i9 in TB4 connection, latter is in i7 with M.2 connection.
and i've done some overclocking, but i don't really know how to properly do it so i just cranked everything to the max and put the fan on maxnium power. (strongly recommend this laptop cooler, it is rather expansive but it will blow like a jet@75dbs, and can cool my laptop from 100 to 70.(dell's crap thermal solution made me do this.)
That was a heck of a lot of difference! Also, i think i just break the record...
The is a small catch, the 3080ti on my machine cannot be detected, after some time of diagnose, it seems that Quadro Driver is not compatible with the Geforce cards. Even disabling the RTX A4000 in the machine is not helping. After all, this might be a thing to remember for future EGPU setups.
Since you're using Windows, use the lastest Geforce driver and make sure Windows update doesn't overwrite it. Geforce driver can deal with a Quadro card, while a Quadro driver can't deal with Geforce(although improved with v511.79)
