Both of them are supported. However, board_status doesn't take variants into account (it shows them as the "parent" board). > Maybe the board owners know, but why do you assume it’s broken, if there > is a success report from May 2019? I guess the question was about the GA-B75M-D3V. In any case, both are pretty similar. > > What's the difference between these two? Well, Gigabyte has pictures of their boards, so why not check it out yourself? You can look up both models on your favorite search engine. In any case, here's a picture of each: GA-B75M-D3H: https://www.gigabyte.com/FileUpload/Product/2/4150/5670_big.jpg GA-B75M-D3V: https://www.gigabyte.com/FileUpload/Product/2/4151/5674_big.jpg So, the D3H has two extra DIMM slots, another PCI slot, a single PCIe x4 slot (note the four pairs of capacitors between the PCIe slot and the "All Japanese Capacitors" text), HDMI and a TPM connector. > Before writing your post, did you check out the source for yourself? > Please do so. > > Commit 1bffc4bd (mb/gigabyte/ga-b75m-d3{h,v}: Switch to variant setup) > [1] sets them up as variants. In layman's terms, if mainboards can be turned into variants, that any of them is known to be working implies that the other variants are working as well. > Also run: > > $ diff -ur > src/mainboard/gigabyte/ga-b75m-d3h/variants/{ga-b75m-d3v,ga-b75m-d3h} > > Then you see, that besides some license header difference, GPIO 17 > differs, the GA-B75M-D3H misses the HDA verb configuration, and it looks > like it has one more HDMI connector. Paul, comparing the source code isn't very useful, as it might be wrong. It is best to draw conclusions from the mainboards themselves, especially given that visual comparison (or even comparing the manufacturer's specifications) is straightforward. For example, have you checked out the change you have linked?
