Although most of the industry agrees that Rambus is an inevitable stage in PC development, PC133 SDRAM is seen as a sensible evolutionary technology and one that confers a number of advantages that make it attractive to chip makers unsure of how long interest in Direct RDRAM will take to materialise. Consequently, in early 1999, a number of non-Intel chipset makers decided to release chipsets that supported the faster PC133 SDRAM.

PC133 SDRAM is capable of transferring data at up to 1.6 GBps - compared with the hitherto conventional speeds of up to 800 MBps - requires no radical changes in motherboard engineering, has no price premium on the memory chips themselves and has no problems in volume supply. With the scheduled availability of Direct RDRAM reportedly slipping, it appeared that Intel had little option than to support PC133 SDRAM, especially given the widespread rumours that chipset and memory manufacturers were working with AMD to ensure that their PC133 SDRAM chips will work on the fast bus on the K6-III processor.

PC133 SDRAM Description

Synchronous Dynamic Random Access Memory (SDRAM) delivers bursts of data at very high speeds using an interface that is synchronized to the CPU clock. SDRAM emerged in 1996, and represented a big step forward from EDO technology. When manufactured, PC133 SDRAM, must meet Intel's requirements (the PC133 Standard) for use with motherboards having a 133MHz FSB (front side bus). PC133 SDRAM compliant is almost always a requirement in Pentium III, AMD Athlon and Power Mac G4 based systems. This link will provide you with a review about Memory Speed.

• PC133 SDRAM DIMM (Compatible with your PC100 and PC66 systems)
• 64mb - 1024mb
• CL2 (CAS=2) or CL3 (CAS=3)
• Non-ECC (Unbuffered) or ECC/Reg
• 168 Pin, Gold Pins
• 3.3 Volt

 

You can use our PC133 SDRAM in your 100MHz FSB, and 66MHz FSB Motherboards that support 168-Pin DIMMs, basically if you need PC100 SDRAM memory or PC66 SDRAM this memory DRAM is also good to use on your PC.

 

Compatibility note: To find PC133 SDRAM memory upgrade compatible with your particular system please see our Memory Configurator.

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.
