The most common type of DDR2 memory for desktop computers is the DDR2 SDRAM DIMM 240 pin.Memory slots and cards connectors pinouts This module utilizes a 240-pin connector found on motherboards designed specifically to house these memory modules. These 240 pins are meticulously arranged to facilitate robust communication between the RAM module and the motherboard's memory controller. Understanding the 240 pin DIMM DDR2 connector layout is essential for proper installation and troubleshooting.DDR2 SDRAM DIMM 240 pin. Pin configurations (Front side / back side). Note: Pin 196 is NC for 512MB, or A13 for 1GB and 2GB; pin 54 is NC for 512MB and 1GB
While the total pin count is 240, not all pins have dedicated functions for every DDR2 module variation. For instance, in DDR2 SDRAM DIMM 240 pin configurations, pin 196 might be NC (Not Connected) for 512MB modules but carry the A13 address signal for 1GB and 2GB capacities. Similarly, pin 54 is NC for 512MB and 1GB modulesFeatures. •240-pin, fully buffered dual in-line memory module. (FBDIMM). • Fast data transfer rates: PC2-4200, PC2-5300, or. PC2-6400.. The address input pins, designated as A0 to A13, along with BA0, BA1 Bank select address pins, are fundamental to how the memory controller accesses specific data locations within the RAM.
The DDR2 DIMM Unbuffered Module (240 pin) pinout signals are complex, involving various VDD (power supply) and VSS (ground) pins, data input/output lines (DQ0-DQ71), clock signals (CLK0, CLK0#), and control signalsDDR 2 | PDF | Computer Memory | Digital Technology. The operational voltage for most DDR2 modules is 1DDR3 Pinout Examples - 4.2 English - UG586.8V, which is a critical parameter to verify when purchasing replacements or checking compatibility. For those looking for specific DDR2 pinout details, resources often provide tables detailing each Slot pin #, Name, Description1GB, 2GB, 4GB (x64, DR) 200-Pin DDR2 SDRAM SODIMM.
For laptops and other compact devices, the DDR2 SO-DIMM is the standard. This module is significantly smaller and features a 200-pin edge connector. Therefore, DDR2 SO DIMM sockets, the pin count is 200 pins, differing from their desktop counterpartsTN-47-03: DDR2 Module Pinout Decode Tables ·200-Pin DDR2 SDRAM SODIMM· Table 2: 200-Pin DDR2 SDRAM SODIMM Pin Assignments (numeric) · Table 3: 200-Pin DDR2 SDRAM .... When searching for laptop memory, terms like "200-Pin DDR2 SDRAM SODIMM" or "DDR2SODIMMpinout" are highly relevantThe following table shows an example of a 16-bit DDR3 interface contained within one bank. This example is for a component interface using a 1 Gb x16 part.. The all possible pins for all DDR2 modules are documented, but specific SO-DIMM modules may not implement every single one.
While DDR2 is a distinct generation, it's important to note its differences from other DDR standards. For example, DDR2 is a completely different protocol from DDR3 or 4, meaning their slots are physically incompatible. You cannot insert a DDR3 module into a DDR2 slot, or vice-versa, due to the differing key notches and pin counts.Memory slots and cards connectors pinouts· 172-Pin MicroDIMM DDR RAM · 17 pin CFAST connector drawing · 50 pin CompactFlash female connector drawing · DDR SDRAM ... This is a crucial point for compatibility, preventing users from attempting to force incompatible modules.
Beyond the standard unbuffered DIMMs, there are also 240-pin, fully buffered dual in-line memory module (FBDIMM) variants, often used in server environments. These modules, like the DDR2 SDRAM FBDIMM 240-pin, 2GB, 4GB, x72 data sheet specifications, offer enhanced features for higher reliability and data throughput, supporting speeds such as PC2-4200, PC2-5300, or PC2-6400.Memory slots and cards connectors pinouts In contrast, DDR4 SDRAM UDIMM modules are more modern and feature a 288-pin, registered dual-in-line, memory module design.
For historical context, earlier technologies like the 184-pin DDR DIMMs used different pin configurations and notches for compatibility with their respective sockets.The 240 pins in aDDR2 DIMM slotare meticulously arranged to facilitate communication between the RAM module and the motherboard's memory controller. While a ... The DDR2 SDRAM interface itself is designed for synchronous operation, allowing for precise timing and the efficient transfer of data.
In summary, understanding the ddr2 slot pinout involves recognizing the specific connector types (240-pin DIMM, 200-pin SO-DIMM), the function of various pins including address, data, and control signals, and the voltage requirements. This knowledge is essential for anyone delving into PC hardware, ensuring correct component selection and successful system assembly or repair. Whether you're looking at the Pinout du module DDR2 4200 SDRAM or general DDR2 ram pinout information, the underlying principles of its sophisticated connection scheme remain constant.
