How PC100 128MB Computer RAM Works for You

Your computer relies on its memory to store information and run the various programs on your PC. The type of memory that can be used in your computer will depend on the type of motherboard and the operating system. When selecting memory, you can choose from different types that enhance the functioning of your device.

PC100 memory is SDRAM (synchronous dynamic random-access memory) designed for use in systems with a 100MHz front side bus. This means that its clock frequency is 100MHz. This memory is used in many Pentium II, Pentium III, AMD K6-III, AMD Athlon, AMD Duron, and Power Mac G4 systems. This type of module is backward-compatible with PC66. DIMM (dual in-line memory module) versions will have 168 pins, while SODIMM (small outline) versions will have 144. These modules operate at 3.3 V. The 128 MB spec means you will have 128 megabytes of RAM.

• Review device information: Gather information about the memory sockets on your motherboard. You will want to know the module type and number of RAM modules needed. You will also want to find out about the OS (operating system) to determine the capacity needed for your computer.
• Select a form factor: If you are using a desktop, you will want to select a DIMM style. SODIMM styles, about half their size, are used in laptops.
• Choose a brand: Once you have determined the type of RAM module needed, you can select from a variety of branded and unbranded units that are compatible with your motherboard.
• Select a capacity: For dual channel setups, you will want to select the 128 MB modules in pairs, which provide a capacity of 256 MB.
• Choose the number of pins: PC100 RAM modules are available with 100, 144, 168, 184, and 240 pins.

• DDR1 SDRAM: This type will have a bus clock of 100-200 MHz. Double data-rate modules allow them to have higher transfer rates. The number of pins on this will determined whether it is a DIMM or SODIMM type.
• DDR2 SDRAM: This type works similarly to DDR1. This type will have a bus clock of 200-533.33 MHz and a transfer rate of 400-1066.67 MT/s, depending on the module.
• EDO DRAM: This type refers to extended-data-output chips designed for 66 MHz Pentium to increase read time.
• SDR SDRAM: This type has a single data rate and transfers one word of data per clock cycle.
• VRAM: This type is found on the computer’s display card and includes the graphics device. It allows graphics cards to use their own memory to process images.

The number of channels used by a motherboard will depend on the CPU socket. Triple-channel designs allow for up to three RAM modules to be synced together. When using triple-channel designs, the three memory modules need to be identical. Motherboards with triple-channel capability will have either three or six sockets. Dual channels work similarly but use two modules at the same time, doubling the memory bus from 64 to 128.
