Kingston 256MB PC133 Desktop Memory

This module provides 256MB of PC133 SDRAM for desktop systems that use the 133MHz bus standard. It operates at a CAS latency of CL3 and a voltage of 3.30V. The stick has no heat spreader attached. It is intended for legacy hardware that specifies PC133 memory.

Suitable for legacy desktops needing PC133 RAM

This module suits owners of older desktops that require PC133 SDRAM with CL3 timing and 3.30V operation. It will not fit systems that need a different memory standard, higher capacity per module, or lower latency than CL3. Builders working on modern platforms or boards requiring registered or ECC memory should look elsewhere.

Deciding specification: PC133 speed rating

The PC133 rating determines whether this module matches the motherboard memory bus. Only boards designed for PC133 SDRAM can use this stick; any system specifying a different speed grade will not be compatible. Verify the motherboard manual lists PC133 support before purchasing.

Questions about this item

What motherboard slot does this 256MB PC 133 module require?

It installs in a standard desktop SDRAM DIMM socket keyed for 3.30V operation.

Will this CL3 stick run reliably with other PC 133 modules already in the system?

Yes, the motherboard will operate all installed PC 133 modules at the slowest CAS latency present.

How can I confirm the module is detected at 256MB and PC 133 speed after installation?

Check the POST memory count or BIOS setup screen; it should show 256MB and a PC 133 / CL3 configuration.
