| Mar 17, 2017 at 7:15 | comment | added | sudo | +1 to Riccardo; I have HT disabled on an HT-capable server, and I see it print "HTT". lscpu is the way to check. | |

| Jul 5, 2014 at 13:41 | comment | added | xebeche | @SilverMoon Then you should report a bug against dmidecode. | |
| Jul 4, 2014 at 3:13 | comment | added | Prashant Pugalia | @xebeche on my system dmidecode output shows "HTT (Multi-threading)" but my processor is "core 2 quad Q8400" which does not have hyperthreading. check intel specifications. | |
| Jul 3, 2014 at 19:09 | comment | added | xebeche | @Silver-Moon Can you explicate? dmidecode reads the SMBIOS and should tell the capabilities of the processor. It does not tell whether hyper-threading is seen or used by the O/S. But this has already been commented on. See also Nils answer | |
| Jun 29, 2014 at 9:05 | comment | added | Prashant Pugalia | the HTT field does not indicate that the processor is actually having hyperthreading in its cores. check the value of 'siblings' and 'cpu cores' in /proc/cpuinfo | |
| Apr 23, 2014 at 18:00 | comment | added | Riccardo Murri | This will only tell you if the processor is HT capable, not if HT is actually being used. | |
