I have a W510 with the i7-720qm processor and 8GB of RAM. My processor score is 4.8 on the Windows Experience Index (WEI), which seems really low relative to what others with the same processor can achieve. I went into the BIOS to set the SpeedStep to maximum for AC power and then decided to monitor the Intel TurboBoost with the Intel montior software, as well as the overall core speed with CPU-Z. I ensure that my Windows and Lenovo Power Management software is set to High Performance and that any processor settings are set to high.
At idle, CPU-Z reports a variable core speed in the 2.7GHz range. Once I start the WEI reassessment, the system drops my core speed to 931MHz and all analysis is completed at that speed, with nary a TurboBoost or increase in the core speed at all !! No wonder my WEI CPU index is so low. So what gives ? What BIOS and/or other settings are required for me to maximize my CPU performance ?

No overheating. I used HWiNFO32 to monitor core speed and core temperature. Pre-assessment temperature was 45 degrees, and nothing went over 50 degrees during the WEI assessment. As soon as the assessment starts it drops the CPU speed. I ran SiSoft Sandra benchmarks and stress testing, and the CPU runs at proper turbo speeds.

So, I installed ThrottleStop and set it to enable full Turbo Mode and then re-ran the WEI assessment. This time the WEI was unable to throttle the CPU back, and I was able to achieve a 6.9 rating on the CPU test. The question still remains though, why is WEI throttling the CPU ?
