Error detected with CPU Z.
I just installed a new H2O system and performed a minor upgrade. Initially, the CPU Z, EVGA's ELEET and AIDA's monitoring showed accurate clock speeds—around 4.0 GHz on the CPU—and within moments it adjusted to about 1263 MHz. After restarting, everything appeared normal again. It’s strange how quickly things settle back. I double-checked the CPU Z in the BIOS and confirmed it was stable. This seems typical for the build. Just curious if this behavior is expected. I upgraded the 5960X to nearly 4.9 GHz but kept the voltage between 1.39 and 41; it seemed too risky, so I reduced it. EVGA X99 Classified came with the latest BIOS (flashing to 1.14), Intel 5960X GSkill, 16MB DDR4, two MSI 970 Gaming in SLI, and a 1000-watt power supply.
It's known as EIST or Enhanced Intel Speedstep Technology. This feature automatically increases your CPU's clock speed to 8 times when the system is idle, helping maintain lower temperatures and conserve energy. You have the option to turn it off in the UEFI settings if preferred.
I often questioned why my CPU speed stayed fixed at 4.4 when using performance mode. I didn’t understand how it affected the results.
