Performance Specifications


	Capacity:		The amount of data that can be transmitted over a specific period of time.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Pin Count		Number of pins in the module.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	DRAM Type
	Your choices are...
	DDR SDRAM		Double data rate SDRAM (DDR SDRAM) is the next generation of the standard SDRAM. DDR allows data to be sent on both the rising and falling edges of clock cycles in a data burst, delivering twice the bandwidth of standard SDRAMs. DDR essentially doubles the memory speed from SDRAMs without increasing the clock frequency.
	SDRAM		Synchronous dynamic random access memory (SDRAM) uses a clock to synchronize signal input and output on a memory chip. The clock is coordinated with the CPU clock so the timing of the memory chips and the timing of the CPU are "in synch." The synchronization eliminates time delays and allows for fast consecutive read and write capability, thereby increasing the overall performance of the computer. SDRAM has two separate memory banks that operate simultaneously, while one bank prepares for access, the other is being accessed. SDRAM allows the CPU to access memory approximately 25 percent faster than EDO memory because the system clock controls it. SDRAM can only be used in computers designed for it and cannot be mixed with any other type of memory. SDRAM can operate at 100MHz, 133Mhz and features a burst mode that allows it to address blocks of information instead of small data bits.
	RDRAM		Rambus DRAM (RDRAM) is an evolutionary type of DRAM that uses a 16 to 18-bit data path and is designed to operate with Front side bus (FSB) speed of 800 MHz producing a burst transfer rate of 1.6 gigahertz. Rambus DRAM technology is a system-wide, chip-to-chip interface design that allows data to pass through a simplified bus. Rambus uses a unique Rambus signaling logic (RSL) technology.
	VRAM		Video RAM (VRAM) has two separate data ports. One is dedicated to updating the image on the screen while the other one is used for changing the image data stored in memory. This "dual-ported" design gives higher performance than DRAM which cannot read and write simultaneously but is more expensive.
	Other		Other unlisted, specialized, or proprietary DRAM types, such as reduced latency DRAM (RLDRAM) and synchronous graphic RAM (SGRAM).
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	Form Factor		The form factor of any memory module describes its size and pin configuration. Most computer systems have memory sockets that can accept only one form factor.
	Your choices are...
	DIMM		Dual in-line memory module (DIMM) provides a 64-bit data path. DIMMs can perform the functions of two single in-line memory modules (SIMMs). Typically, Pentium® processors use a single DIMM instead of two SIMMs. Pentium is a registered trademark of Intel Corporation.
	SO DIMM		Small outline, dual In-line memory modules (SO DIMM) are enhanced versions of standard DIMM. SO DIMMs are about half the length of a typical 72-pin SIMM. These compact DIMMs are used in mobile computing devices. SO DIMMs come in a variety of pin sizes and can be installed either singly to support 32-bit systems, or in pairs to support 64-bit systems.
	uDIMM		Micro single inline memory module (uDIMM).
	AIMM		Accelerated (or advanced) graphics ports (AGP) in-line memory modules (AIMM) allow the graphics controller to directly access texture map data from the main memory rather than having to move it to the graphic controllers' local memory first. This helps increase system speed for processing graphics and allows for a use of a larger portion of memory by "borrowing" storage for texture maps from main memory.
	RIMM		Rambus inline memory modules (RIMM) are designed to install Rambus DRAM (RDRAM).
	SO RIMM		Small outline Rambus inline memory modules (SORIMM) have a smaller profile that standard RIMMs and are used in laptop computers and systems that have strict size requirements.
	Card		The memory is in a card configuration.
	SIMM		Single in-line memory module (SIMM) provides a 32-bit data path. Devices that require wider data paths, such as Pentium® processors, use a pair of SIMMs. Slower processors use a single SIMM. Pentium is a registered trademark of Intel Corporation.
	Other		Other unlisted form factor.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
