and maybe LOCAL APIC MODE to x2apic
What version of windows are you using, I had issues especially with smt on getting 2x64core to boot windows until it was completely update and using pro for workstation. Test in Linux to make sure it works fine first.So there are some problems with CPUs i think. Investigation showes us that there are no way to get them work with more than 4 CCDs. Why they are so slow - don't know, but hangs and restarts are start to happen with more than 4 CCDs are active.
Windows 10 Enterprise. It supports 256 threads as i know.What version of windows are you using, I had issues especially with smt on getting 2x64core to boot windows until it was completely update and using pro for workstation. Test in Linux to make sure it works fine first.
Win 10 Enterprise boots well from m2.nvme. Problems are happened with more than 4 CCDs. Even if I set 6 CCDs with 1+1 core each it hangs.for sure, windows 10 enterprise supports 128 cores/256 threads when x2apic enabled (apic local mode set to x2apic). my cpu's are 7742 oem. i dont know about zs-serie's
when i was installing win 10 enterprise on m2.nvme i couldn't get win10 booted. i could installed on m2.nvme, but not booted.
i went 2,5inch-ssd-way.
@fobus maybe your cpu's are partially broken because they are ES/QS ??
