Used to have Gigabyte X58 ds3 with 2600k cpu, It was running like crap with an unknown issue for a year until switched to Asus made a hell lot of different in a better way, Never bought Gigabyte again eversince.

With stock settings my 1600x vcore goes over 1.5v as well, but fortunately it doesn't cause any instability or temperature issues. I was very surprised about the voltage spikes in the beginning and started browsing forums to seek for an answer. What I found out is that a lot of people were reporting same observations so maybe there is an actual issue with your hardware? 🙁

sometime voltage spikes is because of Turbo Boost + Load Line Calibration setting, turbo boost clocks needs higher voltages and LLC adds a little more, this could result in 1.5v even if stock settings uses 1.325-1.375v grettings

Do correct me if I'm wrong, but isn't Gigabyte kind of famous, or infamous, for releasing newer revisions of boards after launch with actually cheaper components? Ie. rev 1.0 is usually the best, later revisions might be worse. Never had a GB board myself, always used only Asus and, as of late, ASRock. I had one GB graphics card for a while, bought second hand for a SLI setup, and it was fine while it lasted (resold).

Just about every manufacturer will have their good boards and their bad. Just about every person will have their 'favorite' brand that usually ends up being the first good board that they bought, until they eventually get burned on a board and switch to a new favorite. Personally, Asus used to be a favorite until they got popular, and then I started noticing they started cutting corners on their boards, to the point where I could have sworn my ROG Gene V board was built by another manufacturer. For awhile, I switched to Gigabyte until their software support went to shit. MSI was always known for their graphics cards. And Asrock, for awhile, was considered low-end--now people can't stop ranting and raving about their Taichi, which I swear is just good viral marketing. Bottomline, when buying a motherboard, you have to shop smart--you can't always just fall back on a go-to brand.

Sorry to nitpick but X58 is LGA1366 and the 2600k is LGA1155. I know because I still use one for my main rig. Perhaps it was a different CPU?
