There's a post by a Dell moderator in another recent XPS 8930 BIOS update thread saying: "None of the later BIOS added any hardware fixes." So that doesn't sound like they will add any new hardware support, especially since the XPS 8930 is already 3 models behind. That said, XPS 8930 has always been upgradeable to a 9th Gen CPU vs the 8th Gen CPU you have now.  But that may not be worth the cost vs any additional speed or capabilities you don't already have. 64-GB of RAM is max Dell validated in this PC model. Doesn't mean more won't work, but you'd have to search this forum to see if anyone has succeeded in using >64 GB. You shouldn't have any issues with at least a 2T NVME SSD, and possibly a >4 GB SATA HDD, but there's a new thread today about issues getting a 12 GB HDD recognized in the XPS 8930, but not yet fully investigated.
I have a DELL XPS 8930 with an i7-8700K CPU and 64GB of memory. I upgraded from BIOS version 1.1.27 to 1.1.28 as instructed and then to 1.1.30. What does this latest BIOS update bring? CPU? Memory ? Hard disk ? Thank you for your answers.
XPS 8930, new BIOS and what ?
