I was brave enough to try with mine because I had done the same in the past when I had the Dell 9365, and it successfully accepted firmwares from any Dell laptop with the same Thunderbolt controller model. Here is a post of a similar configuration (XPS 9370 + akitio node + 1070) showing what i should obtain in term of performance.ĭoes anyone have a hint for my problem on the update of the TB3 firmware?įlash at your own risk, use common sense and remember that if you flash an incompatible firmware, it could brick the Thunderbolt controller. When I check the current driver and firmware version of the thunderbolt 3 program i obtain the following.Īnd if I try to connect my egpu enclosure I got an error seing that my external device may not work correctly.Īnd indeed when I launch a test of the Egpu, I only obtain half of the expected bandwidth in wrinting speed. Therefore I reinstalled the dell Thunderbolt controller driver and retried to update the firmware. Then I tried to update the Thunderbolt 3 firmware from dell support ( Intel_TBT3_FW_UPDATE_NVM28_3H3DP_A01_4.28.06.001.exe). After installing all this i installed the thunderbolt 3 controller driver ( Intel-Thunderbolt-Controller-Driver_39G55_WIN_17.1.64.250_A04.EXE) from dell support. I started by updating all my drivers and bios by connecting on dell support with my service tag.

But to obtain the full speed of this enclosure connected to the thunderbolt 3 I needed to have the last version of the TB3 Firmware installed (version 25). I was eager to test my External GPU ( Mantiz venus + GTX 1050 Ti + SSD 250) enclosure through Thunderbolt 3. I just acquired a new XPS 13 (9370) with 2 thunderbolt 3 ports pcie x4 and OPI GT4.
