Vossy Posted April 19, 2022 Share Posted April 19, 2022 Hello, I recently upgraded my supermicro X8DT6 motherboard with 2 x 5690 Processors. I thought these CPU had 6 cores but 12 threads as below only showing 6 threads for both. What I am missing? tower-diagnostics-20220419-0844.zip Quote Link to comment

tjb_altf4 Posted April 19, 2022 Share Posted April 19, 2022 If hyperthreading is enabled in BIOS, it might be a result of Spectre-Meltdown mitigations, in which case this thread might help: Quote Link to comment
Vossy Posted April 19, 2022 Author Share Posted April 19, 2022 Thanks all thats exactly what it was. Strange cause the last CPU had it and I didn't change BIOS. Thanks all again Quote Link to comment
