How is linpack OCCT 3b12 supposed to behave on Hyperthreading Intel P4 630 (Prescott). System info says 1 core and running linpack test shows 100% CPU usage in OCCT but only 50% in Process Explorer. Should linpack stress both 'cores'?ĪndyThose are not issues, but they need explanations Using CPU OCCT test with hyperthreading box ticked gives 100% usage in both. * You have to update DirectX9 even on vista (it is DirectX10, but it does have everything for DirectX9 too). * That's hyperthreading I'll try to keep the explanation short & understandable. Hyperthreading causes your OS to see twice the real amount of real cores on your system (for instance, if you've got 2 cores, Windows will see 4). However, you can view those 4 cores as "2 are real, 2 are "benefits only" from HT". So if you load the 2 real cores, and the 2 others are IDLE, you'll see, In the task manager, 50% workload. In reality, you'll have both of your physical cores loaded, and no benefit from HT taken. OCCT CPU test has 2 different behaviours : Those 50% means "95% of the real horse power of your CPU", to keep it short. * Without HT as DC, it will launch one test per physical core (i.e.
