512 MB PC133 Desktop Memory Module

This Kingston module provides 512 MB of PC133 SDRAM for legacy desktop systems. It operates at CAS latency CL3 with a 3.30 V supply and has no heat spreader. The part is suited for restoring or upgrading older computers that require this specific memory standard.

Fits PCs That Accept PC133 CL3 DIMMs

Builders repairing vintage desktops or industrial boards that specify PC133 CL3 memory will find this module compatible. Systems needing higher capacities, faster speeds, lower voltage DDR memory or ECC support cannot use this part.

512 MB Capacity Determines Fit

The single specification that decides suitability is the 512 MB density combined with the PC133 CL3 rating. If the motherboard documentation calls for this exact capacity and timing the module will work; otherwise a different memory specification is required.

Questions about this item

Should I choose the 512MB PC133 module or a different capacity for my older desktop?

This module provides 512MB of PC133 memory. If your motherboard supports PC133 and has a free 168-pin DIMM slot, this capacity will add 512MB to your system total.

What does the PC133 rating mean for actual performance in my machine?

PC133 indicates a 133 MHz data rate with CL3 latency at 3.30V. Your system will run at this speed if the motherboard and chipset support PC133; otherwise it will downshift to the highest supported speed.

Does the 168-pin SDRAM interface limit the maximum bandwidth I can get?

The 168-pin SDRAM interface used by PC133 modules caps theoretical bandwidth at the PC133 specification. Real-world throughput depends on your chipset and memory controller implementation.
