IBM 09N4308 1GB DDR266 ECC Registered DIMM 184-pin

SKU CH-G5TN-E4JJ9

1GB DDR266 ECC registered DIMM for IBM/Lenovo XSeries and Intellistation servers

  • Plug typeRAM Module
  • ECC protection guards data integrity on critical workloads
  • Registered signal processing stabilises high-density server memory
  • 266 MHz DDR266 speed matches legacy platform timing
  • 184-pin DIMM fits IBM eServer XSeries and Intellistation Z Pro Xeon systems
  • 1 GB module expands compatible workstation and server memory

1GB DDR266 ECC Registered DIMM

This 1 GB DDR266 ECC registered DIMM is built for IBM and Lenovo workstations and servers that require registered memory with error correction. It fits 184-pin DIMM slots in compatible EServer XSeries and Intellistation Z Pro Xeon systems.

184-pin DDR266 registered specification

The module runs at 266 MHz to the DDR266/PC2100 standard and uses registered signal processing with ECC error checking. Only systems designed for registered DDR SDRAM DIMMs can accept this part; unbuffered or non-ECC platforms will not work.

Capacity and headroom for legacy servers

A single 1 GB module adds baseline memory to supported XSeries 225, 235, 305, 335, 345 and Intellistation 6221 servers. It handles typical legacy workloads but will not satisfy applications that demand multiple gigabytes per channel or faster memory speeds.

Questions about this item

What real-world bandwidth does the 266 MHz DDR266 rating deliver in a system?

At 266 MHz the module runs at the DDR266/PC2100 data rate, giving the throughput defined by that standard in any compatible server or workstation.

Does the 184-pin DDR266 interface limit the memory speed or capacity in these servers?

The 184-pin DIMM form factor matches the DDR266/PC2100 standard used by the listed IBM EServer XSeries and Intellistation Z Pro Xeon models, so speed and capacity are set by the platform.

Will the 184-pin registered DIMM fit the memory slots in an IBM EServer XSeries 225 or 335?

Yes, the module is specified for EServer XSeries 225 (8647-XXX), 335 (8830-XXX and 8676-XXX), 235 (8671-XXX), 305 (8673-XXX) and 345 (8670-XXX), plus Intellistation Z Pro Xeon 6221-1XX and 6221-2XX.
