spacedrone808, not that I know of and ONLY W10 is officially supported by AMD, so I strongly recommend against it. If you are willing to fight all the dragons, it may well work. Several have gotten 1950X to work on W7. Be sure to ask your MB vendor. Enjoy, John.
Thanks, but i am interested in real life experience, not just theoretical stuff.
Currently using Ryzen 7 1700X with windows 7 x64 without any hassles, in spite of official not supported status.
Real life--Win10x64 is way, way better than Win7x64. Surprised anyone is still using it these days--slow and clunky--ugh...;) But to each his own, etc.
Way better? Win7 Slow? On my 'puter it is a rocket thingie.
More security holes comparing to Win7 [check bulletin board].
Privacy dangerous [Not all telemetry can be turned off].
Full of bugs, but situation is better than in 2015.
More than 2/3 services you are running is not needed, waste of ram.
Atrocious interface with to separate control panels.
I can continue.But enough of off-topic.
No, Threadripper requires Windows 10 or Linux (ideally Linux). If you're talking security, Microsoft blocks updates for Ryzen and Kaby Lake and newer processors on Windows 7, and since it only has 15 months to live, you're going to need to use Windows 10 eventually anyway.
spacedrone808, I strongly recommend you give it a try! As long you are aware that even if it works, W7 does not have a scheduler for Ryzen architecture and other short comings pointed out here. Enjoy, John.
