Howdy, first post here. I am trying to implement the "Disable Hyperthreading" tip from the first post on this thread. My computer is deliberately weak (an Asus Eee Netbook running Windows XP, single Intel Atom CPU N270 @ 1.60 GHz, 1024 MB installed RAM) with an American Megatrends BIOS (ASUS 1005HA ACPI BIOS Rev 1401, Core Version 1401, Build Date 02/26/10, EC Firmware Version EPCD-034). I haven't been able to find any reference to hyperthreading in the BIOS. The only configurable setting that I can find that might apply is on the "Advanced" tab, under "CPU Configuration", there is a "Max CPUID Value Limit" which is set (default) to "Disabled" for Windows XP. When I set this to "Enabled" then boot the computer and run Task Manager (Performance tab) I still show one CPU profile with two graphs that I know are separate because the graphs have slightly different shapes as they move along over time. Family of questions: - Is disabling hyperthreading still the correct approach to improve Inovate (2009 PU1 and 2011) performance on a single core machine? - Is disabling hyperthreading possible on my machine at all? - If disabling hyperthreading is correct and possible, are there required steps that need to be performed that I'm not doing? For now I have set the BIOS back to the factory settings. Thanks, - Osa Fitch osa.fitch@lunacityenterprises.com
