[MAIN\MERGED] Intel Skylake & Kaby Lake Hyperthreading Bug

pepper_chico

It has been confirmed that Intel's Skylake/Kaby Lake hyper-threading can present serious issues that can be fixed by a BIOS/UEFI update that targets Intel processor errata KBL095, KBW095 or the similar one for Kaby Lake processor.

Any plans for such update to come? On Kaby Lake it seems the most safe route at the moment is to simply disable hyper-threading until ASUS provides a new BIOS that addresses this. On Skylake there's the option on ArchLinux side, for example, to install extra/intel-ucode to get microcode updates since there's a fix in revision 0xb9/0xba and later. Windows doesn't have a microcode update for this yet, afaik.

Rename the extracted file mmtool_v5.exe to MMTool.exe

Have been using a software patch to install microcode update on 6700K under Win10 and in some respect it did have some positive effect in some games but seems to be causing a major problem here. While testing latest microcode and playing YouTube HD videos the system just froze dead on me several times over the two weeks. It has never happened before. Going back to previous microcode version that is in the last bios 3401 and recent 3503 seems to cure the YouTube crashing problem. You get micro freezes sometimes (when cpu changes frequencies to idle and back) with 9E but no dead freezes like with BA code.
