1GB PC133 DIMM for legacy systems

This 1GB unbuffered DIMM runs at 133 MHz with CAS latency 3 and 3.3V operation. It fits 168-pin slots in desktops or servers that require PC133 SDRAM. The module uses a 2Rx8 organisation with major-brand chips. It is sold as a single piece for targeted upgrades.

168-pin gold contacts and standard height

The 168-pin edge connector seats directly into the DIMM socket without adapters. Unbuffered design keeps the electrical path short for the chipset. Gold-plated contacts resist oxidation during long service intervals. Physical dimensions follow the JEDEC outline so the module clears standard retention clips.

Replaces smaller PC133 modules or fills empty banks

Use this stick to raise total memory in machines capped at 1GB per slot. The jump is worth it when the operating system or applications hit the previous limit and the board accepts 128Mx64 density. It will not help systems that need registered or ECC memory, nor boards limited to lower-density chips.

Questions about this item

What does the PC133 133 MHz standard cap the data rate at?

The PC133 standard limits the memory bus to 133 MHz, so this module transfers data at that clock speed.

What slot and pin count does this 168-pin DIMM require?

It fits a 168-pin SDRAM DIMM slot; the notch position matches the 3.3 V keying on the motherboard.

How is the module installed and what step is often missed?

Align the notch, press firmly until both side clips click; the common mistake is stopping before the clips latch fully.
