There is a known issue in Process Lasso v9.8.0 affecting some Threadripper 1xxx/2xxx systems in 'Distributed Mode'. In this mode, only 1/2 of CPU cores will be shown in the Process Lasso CPU core graphs. The problem is entirely cosmetic, affecting only those graphs.
Users can resolve it by ensuring the 'Memory Channel' setting in their BIOS/UEFI is set to 'Interleave' or 'Channel'. If using Ryzen Master, switching to 'Local Mode' is the same.
In fact, users may find Local Mode preferable, as it properly maps NUMA nodes to the most efficient (local) memory channels.
The first beta of 9.8.1 is now available with a fix. Users can give it a try by checking 'Update / Include betas versions', then updating.
