FAQ's
What does ECC mean in this memory module? ECC stands for Error Checking and Correction, a feature that detects and corrects common types of data corruption to maintain system integrity during operation. Is the 33L3321 compatible with non-IBM systems? This module is designed specifically for IBM platforms; compatibility with non-IBM systems is not guaranteed and should be verified with system specifications. What is the significance of the 133MHz PC133 specification? PC133 indicates the memory operates at a clock speed of 133MHz, which defines its data transfer rate and compatibility with systems supporting the PC133 standard. What does Registered DIMM (RDIMM) mean? RDIMM modules include a register that buffers control signals, improving signal integrity and allowing for higher memory capacities in server and workstation environments. What is memory rank in this context? Memory rank refers to the organization of the memory chips on the module, affecting how the system accesses memory; this module includes rank memory as specified by IBM. Can this memory be used in modern systems? This 128MB PC133 ECC RDIMM is intended for older IBM systems; modern systems typically use different memory standards and capacities.
