Socket 604 is a CPU socket for Intel’s Xeon processors, released in 2002. It has 603 active contacts and a dummy pin, and is compatible with Xeon CPUs with a data transfer rate of 400-1.066 MHz. It adheres to the PGA form factor and offers a zero insertion force feature. Socket 604 processors were manufactured using the 130-, 90-, 65-, or 45-nanometer manufacturing process. It was replaced by later sockets such as LGA 775, LGA771/Socket J, LGA 1366/Socket B, LGA 1156/Socket H, and LGA 1567.
Socket 604 is a Central Processing Unit (CPU) socket that Intel Corporation released in 2002 for its Xeon processor brand. The CPU socket was designed to electrically connect the CPU to the motherboard for data transfer. It also provides physical support and acts as a protective interface so that users have less chance of damaging the CPU during removal or insertion.
Intel named the Socket 604 after the number of holes it has. The contacts, on the other hand, consist of 603 active contacts and a dummy pin. These contacts, which support the processor and have a pin pitch of 0.05 inches (1.27 millimeters), are arranged in neat rows along the socket’s square frame. Therefore, it adheres to the pin grid array (PGA) form factor. Intel offers a zero insertion force feature so that no force is required to remove and insert the chip.
The only Intel CPU brand compatible with Socket 604 is Intel Xeon. Debuting in 1998, Xeon was designed for server and workstation motherboards as well as embedded systems. However, not all Xeon CPUs are socket compatible. The socket-mounted chip must have a data transfer rate of 400, 533, 667, 800, or 1.066 megahertz (MHz), which translates to 400 million, 533 million, 667 million, 800 million, and 1.06 billion transfers per second.
Additionally, Socket 604 processors were manufactured using the 130-, 90-, 65-, or 45-nanometer manufacturing process, which determines their size. The smaller the lithography node number, the smaller the CPU. The Intel E7500, E750, E7205, E7320, E7520, and E7525 are the Socket 604 compatible Intel Xeon chip sets.
The active 603 contacts rather than the full 604 would suggest that Socket 604 compatible Xeon chips may work on Socket 603, which was released in 2001 and is the immediate predecessor of Socket 604. However, they may not work because the processors still have that 604th pin more. Socket 603 compatible Xeon chips, however, can go on Socket 604, since they don’t need the dummy pin.
Although Land Grid Array (LGA) 775, or Socket T, appeared to threaten the Xeon supremacy of Socket 604 with its 2004 debut, it was only compatible with 400 MHz Xeon CPUs. It also actually had a transfer rate requirement lower data with its 133 to 400 MHz range. Later sockets, however, such as Socket M and LGA771/Socket J in 2006, LGA 1366/Socket B in 2008, LGA 1156/Socket H in 2009, and LGA 1567 in 2010, they replaced the Socket 604.
