Hopefully the updates will work for the i7-5775C as well. I've distilled this and the i7-5700HQ microcode into a GitHub repository, along with an install script. After some stress-testing my machine seems stable, without any of the kernel flags and with default UEFI settings! https://github.com/bgw/bdw-ucode-update-tool -- You are receiving this mail because: You are the assignee for the bug.
