What is Simm?

Simm, which means the Single in Line Memory, is a type of computer memory used in the X86 and Pentium family on computers as well as selected laser printers. SIMM consists of a small plate with circuits that hold two to 32 chips with random access (RAM) and connects to sockets that operate an 8 -bit or 32 -bit bus. There are two different types: a 30-pin module for older X86 computers and a 72-round module common in 486 and Pentium systems. Modules may contain parity or no parity. Soon after, Simms became the standard for memory modules and replaced the memory chips for DIP and SIPP, which occupied much more space on the motherboard. The SIMM was subsequently replaced by a dual module in a line or DIMM. Each module provides one byte, or 8 bits, plus one additional bit, if there is a element chip, data. On the other hand, the 72-round module can come in sizes from 1 MB to 2,048 MB and provide four bytes or 32 bits of data at the same time.

One of the primary differences between SIMM and DIMMS lies in the position of pins or electrical contacts. The contacts along the front edge of the SIMM module are repeated again at the rear. Contacts on DIMM modules differ for each side. Data path size is another remarkable difference between DIMM and SIMM. DIMM uses a 64 -bit data path, while SIMM is limited to 32 bits. Finally, the SIMMS must be installed in pairs to function properly, while only one DIMM module is required at a time.

Installing Simms as part of the computer's memory upgrade is a relatively easy process. Always hear from technical manuals before performing any upgrades and verify the type of memory.

turn off and disconnect your computer first. Remove the case and look for memory slots on the motherboard. UnravelE extra static electricity by touching a metal object. Then hold the memory module around the edges to avoid direct contact with the pins, insert the module into an empty socket at 60 ° and turn it in place until the module is perpendicular to the motherboard. Replace your computer cover, re -connect the cables and turn on the computer. In most cases, the system should recognize a new memory.
