Core Disagreement

SQX reports 64 cores. I have 60 Cores (120 logical).

SQx can only use 1 Group of threads and Windows max for one group is 64 core or threads. So either You run 2 SQx or You turn of Hyper threading in Bios and run with 60 Cores and it will max out all 60 cores using one SQx. Hmm You must have 4 Cpu's.


Nice machine Nathan :)

Thanks. Good to hear it confirmed. I disabled logical cores, and that presents just the 60 physical cores to the OS and solves it.


Curious if there are any other BIOS settings that SQX can benefit from? Currently I have mine setup with:


Node Interleaving=Disabled

Virtualization Technology=Enabled

Turbo=On

Execute Disable=Enabled

C1E=Enabled

Logical Cores=Disabled


I think Node Interleaving and Logical Cores are the most influential BIOS settings, but I have only a rudimentary understanding of what the above all do- if anything at all with respect to SQX performance.
