I believe this is our culprit like alex said:I wonder if there is a bug in CPUz.
If it's any help the BCD has options to make processor groups on single socket systems. It's not ideal and a little buggy but does have it's uses when not having access to a multi socket system.I have a feeling its something like this... The Chess programmers just didn't have access to multi processor systems. Even Tamas from AIDA64 doesn't, I have been a help to him also.
how do i use bcd to set processor group? maybe what i could do is set a group with max number of logical cores of 64 and hopefully cpuz will use that group. still not ideal...If it's any help the BCD has options to make processor groups on single socket systems.

Single 2683v3, running on group 1 with 12 threads
Note that distribution isn't always even. Also things can get a little funky with OSes that only support one socket such as "Home" so might be better of with "Pro" or equivalent or perhaps a server version.
For CPU-Z bench I would recommend bringing it up with Franck at CPUID. If you can discus in French then even better. BTW I don't think CBR11.5 supports groups either. So many softwares not able to take advantage...
In win7 you could set the affinity of the process and it should stick to one CPU (or any number of cores you want). IIRC, win10 ignores the affinity set through task manager and you need to make a batch script or shortcut to do it.I was thinking also. is there anything a program could do to truly benchmark 1 cpu only in a machine with dual cpu? like for instance, I ran cinebench with just one 2686 v3 in the MB and got a cinebench score of 1988. in dual cpu, it's 3780. but I am just wondering if it's possible for a benchmark program to do something like that or does the presence of a 2nd cpu makes that impossible? it's good a lot of time to know this and I think cinebench should have this feature if possible truly bench only 1 cpu in a machine with dual cpu since this single cpu bench would help a lot of people only running single cpu socket boards.
but will that truly give a correct benchmark of running only a single cpu or would that just half the cinebench of a dual cpu system?In win7 you could set the affinity of the process and it should stick to one CPU (or any number of cores you want).

don't think anyone would make a bios setting for that. that just promote lazy software writing.Maybe a short term solution can be limit in bios (some server platform can do it) so thath the system see only 64 cpu, that, maybe, can permit a not processor group aware software to use (in your case) 64 cpu instead of 36.
Licensing cost can justify this ))don't think anyone would make a bios setting for that. that just promote lazy software writing.
