512 MB PC133 ECC registered DIMM

This 512 MB PC133 CL3 ECC registered DIMM is built for legacy desktop systems that require registered memory with error correction. It suits repair technicians and hobbyists maintaining hardware that uses the PC133 standard. The module provides basic capacity for older workstations or servers that depend on registered buffering. Buyers needing higher density or faster speeds should look elsewhere.

MT18LSDT6472G-133D2 part detail

Questions about this item

Will the registered ECC design require any special handling when I install or remove the module?

The registered buffer adds a slight mechanical height; handle the DIMM by its edges and seat it firmly until the retention clips click, just as with any standard desktop module.

What is the first limitation I will hit when running this memory continuously at its rated 133 MHz speed?

The CL3 latency and 133 MHz bus set the maximum sustainable bandwidth; sustained workloads will be bound by that throughput ceiling rather than thermal or voltage limits.
