PC133 SDRAM DIMM 512MB

This 168-pin unbuffered module delivers 512MB of PC133 SDRAM at 133MHz with CAS latency 3. It operates at 3.3V and uses a 2Rx8 chip configuration built with major-brand components. The stick is sold individually as a system-specific upgrade for legacy platforms.

Buyers with SDRAM-only motherboards

This module suits systems that accept 168-pin PC133 DIMMs and do not require ECC or registered buffering. Buyers whose boards need registered memory, error-correcting code, or a different pin count should look at something else. Mixing with slower modules will reduce overall speed to the lowest installed rating.

168-pin PC133 interface

The 168-pin DIMM form factor and PC133 signalling are the single specification that decides fitment. If the motherboard manual calls for 168-pin unbuffered SDRAM at 133MHz, this part matches; otherwise it will not seat or function.

Questions about this item

What comes in the box with this 512MB PC133 DIMM and is anything else needed?

The package contains one 512MB 168-pin unbuffered DIMM; no additional parts or cables are required for installation.

How do I choose between the available versions of this 512MB module?

Only the single 512MB 133 MHz CL3 variant is offered, so there is no alternative capacity or speed to select.

What does the 133 MHz rating mean once the module is installed in my system?

The memory will operate at up to 133 MHz with CL3 timing, and the system will run all installed modules at the speed of the slowest one present.
