256 MB PC800 ECC RIMM

This Samsung Rambus RIMM provides 256 MB of PC800 server memory at 800 MHz with ECC error correction. The 184-pin module includes aluminium heatsinks and is designed for workstations and servers that require registered RDRAM. Most compatible platforms expect modules installed in matched pairs for stable operation.

Thermals and power

Aluminium heatsinks on each module dissipate heat without active cooling, keeping the memory silent during normal workloads. RDRAM architecture delivers high bandwidth while maintaining system stability at the rated 40 ns latency. Power draw is consistent with standard PC800 specifications for this capacity.

Upgrade context

This module replaces failed or missing PC800 RIMMs in legacy Pentium 4-era servers and workstations that mandate ECC RDRAM in pairs. The jump is worthwhile when restoring dual-channel bandwidth or adding ECC protection to a supported chassis. Systems requiring DDR, SDRAM or later memory standards cannot use this module.

Perguntas sobre este artigo

How do I install the 184-pin RIMM module and what step is often missed?

Insert the module into the RIMM slot until the retaining clips lock, then install a second identical 256MB PC800 ECC module in the paired slot because most Pentium 4 systems require matched pairs for the memory controller to initialise.

What maintenance or replacement will the 256MB PC800 ECC RIMM need later?

The aluminium heatsinks are passive and require no service; replacement is only necessary if a module fails or if the system is upgraded to a larger capacity using matched pairs of the same speed and ECC type.

What limit appears first when the 800MHz RDRAM runs under sustained load?

The 40ns latency and fixed 800MHz clock set the bandwidth ceiling, so sustained throughput cannot exceed the PC800 rating regardless of workload duration.
