Question: I bought a dedicated server with dual E5-1650 v3 processors. Intel website shows 3.5 Ghz base speed but WHM reports only 1200 Mhz per core. Is there anything wrong with my server?
Answer: no, this is normal because your server uses Enhanced Intel Speedstep Technology (EIST):
Enhanced Intel SpeedStep® Technology allows the system to dynamically adjust processor voltage and core frequency, decreasing average power consumption and heat production.
By decreasing power and heat on servers, system builders can potentially lower acoustics, depending on system configurations. They can also develop more innovative small form factor designs.
The feature also helps address power concerns in companies with sites approaching the limits of bounded electrical infrastructures. Combined with existing power-saving features, Enhanced Intel SpeedStep Technology can provide balance between power production and consumption. It uses design strategies that include the following:
- Separation between voltage and frequency changes. Stepping voltage up and down in small increments separately from frequency changes allows the processor to reduce periods of system unavailability (which occur during frequency change). The system can transition between voltage and frequency states more often, providing improved power/performance balance.
- Clock partitioning and recovery. The bus clock continues running during state transition, when the core clock and phase-locked loop are stopped. Logic remains active. The core clock can also restart more quickly under Enhanced Intel SpeedStep Technology than under previous architectures.
