Do you have a solution?
As you saw, the Base Clock (BCLK) is slightly high, at 140MHz instead of 133MHz. That might be due to a BIOS adjustment of the BCLK for the CPU, or due to overclocking memory. You should check you BIOS and see if it is set to 140 and change it to 133.
On the other hand, the reason why you see an error on your BCLK is because it is just slightly outside of the tolerance setting in the test configuration, which is set to +/- 5%. Five percent of 133 = 6.65, so the range of BCLK values that will pass are from 126.35 to 139.65. BCLK is really an integer without a fraction, but 140 is just outside of the tolerance. You can set the BaseClock Tolerance from the Config option at the top of the IPDT window, and increase it to say 10%, so that test will pass and the program will continue.
Regardless, I don't think that is what is causing that core to run at 60% all the time. Your CPU may be defective, and the only "fix" for that is to return it to your retailer or Intel. If you can change BCLK to 133 in your BIOS, run the CPU test again and see if it fails again. If you cannot change it and it is stuck in the CPU at 140, that may be enough to show the CPU is defective. You could use the test results to show the CPU is defective and have it exchanged.
It is also possible that your mother board is not working correctly and causing the CPU to run strangely as it is. That is difficult to test and diagnose.
I suggest you don't worry to much about the BCLK error and focus on the strange core usage value, which is likely the CPU. Change the BCLK tolerance value in the Config of the IPDT program, and let all the tests complete.
