What Socket Board Is an HP DC7600?
When computer technology company Hewlett-Packard released the HP Compaq dc7600 desktop personal computer in 2006, it offered 26 processor, or central processing unit, choices from semiconductor company Intel Corp. This was made possible by the computer's motherboard, which has a CPU socket called Socket 775, more commonly known as the LGA 775.

General Description
-
The HP Compaq dc7600's LGA 775 is named after the 775 contacts it has for accommodating the processor. Like other CPU sockets, it serves two purposes. It electrically connects the CPU to the motherboard for data transfer, as well as interaction with other components of the dc7600. It also provides physical support for the CPU to prevent possible damage during insertion or removal.
Manufacture
-
Also known as Socket T, the LGA 775's letters actually comprise an acronym, which stands for "Land Grid Array." It is similar to a popular type of integrated circuit packaging called Pin Grid Array (PGA), which is named after the orderly, gridlike layout of its pin contacts on a square-shaped substrate. LGA, though, has the pins -- gold-plated ones -- on the socket rather than on the processor. The LGA 775 measures 1.48 by 1.48 inches, or 3.75 by 3.75 centimeters, with its middle cut out.

Processor Choices
-
When it was released in 2004, Intel Corp. made the LGA 775 for accommodating the Pentium, which was the company's highest-end, consumer-oriented CPU at the time, and the low-end Celeron. For the socket mounted on the HP Compaq dc7600, HP offers three chips from the higher-end, Pentium-based Celeron variant Celeron D, 13 chips from the Intel Pentium 4 brand with Hyper-Threading Technology for enhanced multitasking and 10 chips from the higher-end, dual-core Intel Pentium D subdivision of the Pentium 4.
Upgrade
-
In 2006, with the debut of the Core brand, which would eventually replace the Pentium as the Intel flagship brand -- Intel Corp. expanded the processor compatibility of LGA 775. As a result, users can replace the single-core Pentium or Celeron chip of the dc7600 with a more powerful dual-core or quad-core processor from the Core 2 Duo, Core 2 Quad or the top-level Core 2 Extreme edition of the Core brand.
