My Windows 7 (Professional from MSDNAA) doesn't recognize both cores of my T 5550. Device manager shows 2 CPUs, so does Intel's CPU identifier tool. However, most Applications and 7's Performance Monitor detect only one.
I tried the msconfig solution I found in various forums but I can't select 2 Processors in the startup options. The "detect HAL" checkbox I saw in various Posts isn't there either. I also tried editing the environment variables but it didn't help either.
Thanks in advance
