![]() ![]() High speed 1066, 800, 711 and 600 MHz RDRAM storageġ84 edge connector pads with 1mm pad spacing The Rambus ® RIMM™ module is a general purpose high-performance memory module suitable for use in a broad range of applications including computer memory, personal computers, workstations, and other applications where high bandwidth and low latency are required. They have one small notche within the row of pins along the bottom of the module. 184-pin DIMMs are 5.375″ long and 1.375″ high, and the heights may vary. The number of chips on a 184-pin DIMM may vary, but they have 92 pins on the front and 92 pins on the back for a total of 184. 168-pin DIMMs are available in PC2100, PC2700, PC3200 and PC3500 and later. Each 184-pin DIMM provides a 64-bit data path, so they are installed alone in 64-bit systems. These memory modules are primarily used in newer computers and can be inserted one at a time unlike the SIMMs, which have to be inserted in pairs.ġ84-pin DIMMs are for DDR SDRAM modules found in Pentium III and 4 and Athlon systems. There is one notche on the bottom of the board and it must be aligned properly in order for them to be inserted. They contain 184 pins on the bottom of the circuit board. The DIMM is larger than either of the SIMMs. They have two small notches within the row of pins along the bottom of the module. 168-pin DIMMs are 5.375″ long and 1.375″ high, and the heights may vary. The number of chips on a 168-pin DIMM may vary, but they have 84 pins on the front and 84 pins on the back for a total of 168. 168-pin DIMMs are available in FPM, EDO, PC66, PC100 and PC133. Each 168-pin DIMM provides a 64-bit data path, so they are installed alone in 64-bit systems. These memory modules are primarily used in newer computers and can be inserted one at a time unlike the SIMMs, which have to be inserted in pairs.ġ68-pin DIMMs are found in Pentium and Athlon systems. There are two notches on the bottom of the board and they must be aligned properly in order for them to be inserted. They contain 168 pins on the bottom of the circuit board. Each 72-pin SIMM provides a 32-bit data path, so they can be installed alone in 32-bit systems (486 models) but must be installed in pairs in 64-bit Pentium or AMD Athlon systems. ![]() Because the notch is not centered they can only be put in one way.ħ2-pin SIMMs are found in older desktop 486 and Pentium computers. A 72Pin SIMM has 72 pins on the bottom of the circuit board, 36 on each side There is a notch cut in the bottom of the circuit board in the mi dd le. ![]()
