128 MB PC133 168-pin DIMM module

This 128 MB SDRAM DIMM runs at 133 MHz with CL3 timing and 3.3 V unbuffered operation. It uses a 168-pin connector and a 2Rx8 rank layout built with major-brand chips. The module is sold as a single piece and carries a limited lifetime warranty against manufacturing defects from the manufacturer.

Suits legacy systems needing PC133 SDRAM

The part matches older desktops or servers that accept 168-pin PC133 unbuffered DIMMs without ECC. Systems requiring registered memory, ECC error correction, lower-voltage DDR types, or capacities above 128 MB per slot cannot use this module.

168-pin PC133 interface decides fit

The 168-pin PC133 interface is the single specification that determines whether this DIMM will install and function. Verify the motherboard manual for 168-pin PC133 unbuffered support before purchase.

Questions about this item

Will this PC133 DIMM run at its rated 133 MHz speed if I keep my existing slower SDRAM modules installed?

All memory in the system will run at the speed of the slowest module, so this stick will downclock to match any slower SDRAM already present.

How can I confirm the module is operating at PC133 CL3 after installation?

Enter the BIOS or use a system-information utility; the memory should report 133 MHz speed and 3-3-3 timings.

Does the single 128 MB stick ship alone or with extra brackets or cables?

The package contains only the 168-pin DIMM; no brackets, cables or additional hardware are included.
