The Intel E5440 is a quad-core CPU, meaning it runs with four cores and four threads for optimal data transfer rates and even process distribution. This 2.83 GHz CPU uses FSB parity and has an FSB speed of 1333 MHz. In addition, Intel thermal monitoring technology is a key feature for this Intel Xeon processor. This function automatically detects the core temperature of the CPU and makes the necessary adjustments within the structure to maintain a proper operating temperature to prevent device failure. The Intel E5440 also features execute disable bit, which acts as a security feature that blocks potentially harmful data, files, and prog from entering the system. Some of the other features for this Intel Xeon processor include Intel VT-x with Extended Page Tables, Intel demand-based switching, Intel 64, and idle states. The demand-based switching technology allows the processor to run at a maximum speed while using a minimal amount of voltage. Furthermore, some embedded options are available and can be accessed by advanced technicians. The Intel Xeon processor offers a lithography of 45 nm and a maximum TDP of 80 watts. Overall, this 2.83 GHz CPU is easy to install and provides advanced technological features for a secure and smooth-running system.
