Dell's recent BIOS update for the XPS 15 7590 fixes the GPU throttling issue that was reported earlier. As observed by a Redditor, the new update apparently does not allow the GTX 1650 to cross the 71 °C while also offering some headroom for overclocking with a minimal undervolt.

And they dont care about 9560, 9570 users with similair issues. Great move Dell
But...what is the BIOS version number that corrects this issue so that current and future readers will know what to look for????
