256 MB PC133 CL3 desktop module

This Kingston KVR133X64C3SS/256 module delivers 256 MB of PC133 SDRAM with a CL3 latency rating and operates at 3.30 V. It is a standard unbuffered DIMM without a heat spreader, designed for desktop systems that accept PC133 memory.

Suits legacy PC133 upgrades.

Builders restoring or maintaining older desktops that specifically require PC133 CL3 modules at 3.30 V will find this part a direct match. Systems that need larger capacities, lower latencies, different voltages or newer memory standards cannot use this module.

256 MB capacity decides fit

The single specification that determines compatibility is the 256 MB density; the motherboard must support this exact capacity per slot along with the PC133 speed and CL3 timing.
