SDRAM Memory

"SDRAM memory stands for short Synchronous DRAM, a type of DRAM that can run at much higher clock speeds than conventional memory. SDRAM Memory  actually synchronizes itself with the CPU's bus and is capable of running at 133 MHz, about three times faster than conventional FPM RAM, and about twice as fast EDO DRAM and BEDO DRAM. SDRAM is replacing EDO DRAM in many newer computers." (www.webopedia.com)

PC133 SDRAM (Synchronous DRAM) memory

PC133 SDRAM (Synchronous DRAM) memory modules are designed to help memory keep pace with the processor performance demands on the memory subsystem. PC133 SDRAM has the same design, process and infrastructure as PC100 SDRAM and thus offers the most natural migration path for improved system memory performance. The modules are used in a variety of high performance desktop PCs and meet 100% full Intel and Apple Specs. Fully Athlon Compatible. Supports Serial Presence Detect (SPD).

Allmemoryupgrades.com offers PC133 SDRAM memory modules in capacities up to 512MB which are designed for high performance, compatibility and maximum reliability. Our memory upgrades are built to conform to the JEDEC standard and have the same operating voltage and architecture as PC100 SDRAM memory modules.

Compatibility note: you can use our SDRAM memory in your PC133 MHz FSB, 100MHz FSB, and 66MHz FSB Motherboards that support 168-Pin DIMMs, basically if you need PC100 SDRAM memory or PC66 this DRAM memory is also good to use on your PC. To find SDRAM memory upgrade compatible with your particular system please see our Memory Configurator.

Memory Knowledgebase:

Memory types like SDRAM, DDR, and Rambus RDRAM are found in most of today's computer memory applications:

• SDRAM - Synchronous Dynamic Random Access Memory;
• RDRAM - Rambus Dynamic Random Access Memory;
• DRAM - Dynamic Random Access Memory;
• RAM - Random Access Memory;
• DDR - Double Data Rate is a type of SDRAM in which data is sent on both the rising and falling edges of clock cycles in a data burst.
• DIMM - Dual in-line Memory Module. This physical property describes a module with signal and power pins on both sides of the board. DIMMs can be any number of pins including 144pin SODIMM SDRAM, 168pin SDRAM memory, and 184pin DDR SDRAM.
• Unbuffered - This is the most common configuration for memory. These modules do not use any supporting TTL logic.
• ECC - Error Correcting Code. Logic designed to detect and correct memory errors. Memory modules designed with 72 bits of memory support the motherboard's ECC function.
• Registered - Registers delay memory information for one clock cycle to ensure all communication from the chipset is collected by the clock edge, providing a controlled delay on heavily loaded memories. This allows you to installed four or more modules or larger memory sizes in your application. Registered and non-registered memory can not be mixed.
