Hi! My notebook has a i5 3427 ULV processor. It's rated to run at 1.8Ghz and under load due to intel speed step it should decrease it's multiplier to be at a lower frequency. According to CPU-Z it's multiplier has a range of 8-27. But I have noticed that it always runs at multiplier=8(freq=0.77 Ghz). I thought the low speed was due to low workload but even on running Prime95 torture test. It keeps the CPU utilization at a constant 44% at 0.77 Ghz. The frequency and multiplier don't change as they should. I even changed the power setting of Windows to High Performance and it has no effect on it. Can this indicate a problem with my system, Any other tips on things I should check?

Hi Alan.W,
The processor speed and core rate will increase or decrease automatically as the system needs it. Based on your description, my best recommendation for you is to run the Intel® Processor Diagnostic Tool. This software will test and diagnose every internal component in the processor and will generate a result. You can get the software at the following link:

Another good recommendation is to contact the computer manufacturer so they can help you with troubleshooting steps ir a possible replacement.
