From: Tester on 25 Mar 2010 11:44 Hello there, This is an odd question. If I have a dual or quad core processor is there any way to restrict windows server to only use one CPU core? I know multithreading can be disabled in the computer Bios but have not heard yet of disabing CPU cores. Thank you, T

As for you question. I've not seen anything outside of virtualization that allows you to disable multicores. Do you mind if I ask why you would want to?
From: Tester on 25 Mar 2010 12:10 Hi, Not at all, some software manufacturers license per CPU or core and I have not seen anywhere you can disable the cores. I am thinking if when I install the server I only select under device manager, hardware ACPI Uniprocessor PC, will windows use only one CPU or core then? Thanks, T

I could see wanting to do that for benchmarking purposes, to determine just how much cpu to spec for an application. D |
