Guest John7 Posted June 11, 2008 Posted June 11, 2008 Hi, On a customer's system the second "cpu"does not show although: + CPU supports hyperthreading, + BIOS has hyperthreading enabled + ACPI 2.0 enabled. + Windows "ACPI multiprocesor-pc" CPU device driver manualy selected. + New hardware detected, 2x reboot. But in Device Manager still 1 processor listed. In Task Manager still 1 Performance Window. How to fully enable hyperthreading ? System description P4 3GHz with hyperthreading. 2GB DDR400 WinXP Home + SP3 Office 2007 All updates NOD32 A/V RocketDock desktop enhancement TIA, John7
Guest AJR Posted June 11, 2008 Posted June 11, 2008 Re: Hyperthreading CPU but 2nd "CPU" not shown Some Confusion - hyperthreading permits "one" processor to process more than one thread concurrently (providing application is programmed to take advantage). Hyperthreading by itself does not indicate multiple cores or processors.

Guest R. McCarty Posted June 12, 2008 Posted June 12, 2008 Re: Hyperthreading CPU but 2nd "CPU" not shown Do a Repair or In-Place install and do not forcibly select the HAL. If the Motherboard is ACPI compliant, it should inform XP that it can support HT enabled processors and select the right Computer driver. Also making demands isn't welcome here, especially since you are working for pay on this problem.

You manually installed a driver for "ACPI Multi". Have you done the windows updates since, not the express ones, the custom ones and then the optional hardware ones? Have you also updated your BIOS to the most current version? -- - Igitur qui desiderat pacem, praeparet bellum. - Calling an illegal alien an "undocumented worker" is like calling a drug dealer an "unlicensed pharmacist" spam999free@rrohio.com (remove 999 for proper email address)
