Not my Haswell e 5820K ......

but, it's reported that KB4346084 resolves the issue. Several users report that uninstalling KB4100347 and installing KB4346084 restores the overclocked settings, though it's not clear if the former update actually needs uninstalled—the latter one is supposed to override it.

It seems to affect certain BIOS' and MBs, not the whole X99 spectrum. I have a 5820K too, but I don't overclock. Also, Isn't the KB4346084 Intel update for Skylake and up and not ment for Broadwell/Haswell? All these KB articles and microcodes are really confusing…

I'm as confused as you :)

The link above came up on my phone "feed" this morning so I figured I'd link others to it in case they had issues


it does indeed look like it's for all the 'lake Processors looking at this :
