According to the following:
http://support.dell.com/support/edocs/systems/insp560mt/en/sm/setup.htm
I should see a setting for disabling and enabling Hyper-threading in the BIOS.
The first option is missing from the BIOS. I checked the processor itself and it is stated as having the capability of running hyper-threading. Documentation claims that the option is there in the BIOS for this computer model, but the option is nowhere to be found. Anyone have any idea why that is?
Intel says that the processor does not have Hyper-threading capability but CPU utilities such as "coreinfo" show that the processor is capable of running it. Below is part of the output.
