This machine is very stable and performs well, but the clock speed stays consistently around 798.95Mhz or 799.24Mhz regardless of settings. I changed all BIOS options—turbo, OS management—but nothing affected it. It runs smoothly until I ran bench tests. Results show capacity usage between 25-33%. I’m aware enough to be cautious. Need help?
The voltage adjustment works automatically since it's a standard i5 4690 built into the regular HP motherboard. The voltage and CPU frequency should increase when under stress, yet they remain fixed. Testing Prime95 on the Small FFT power/heat/cpu benchmark showed full load with a 100% utilization rate and a 4°C temperature increase, while CPU-Z displayed 0.72–0.73 volts and maintained the same 800MHz core speed.
It seems the system is actually operating around 3.48Ghz, though readings vary between tools like CPU-Z and CPUID depending on mode. The Intel Processor Diagnostic Tool also confirms this value. The discrepancy in readings might be due to factors such as Safe Mode activation or hardware configuration.
