133MHz SDRAM module may be a valid replacement for the PC100 SDRAM - Servers

Troubleshooting


Problem

33MHz SDRAM module may be a valid replacement for the PC100 SDRAM for Servers.

Resolving The Problem

Source

RETAIN tip H174722

Symptom

You order a PC100 SDRAM memory module as an option or as a replacement part number (FRU), but the memory module that you receive is labeled as a PC133 SDRAM module.
 
NOTE: The FRU and option numbers are listed on the large IBM barcode label.

Affected configurations

The system may be any of the following IBM eserver xSeries servers:

  • An xSeries 370, type 8681, any model
  • An xSeries 350, type 8682, any model
  • An xSeries 250, type 8665, any model

The system may be any of the following IBM Netfinity servers:

  • A Netfinity 8500R server, type 8681, any model
  • A Netfinity 7600 server, type 8665, any model
  • A Netfinity 7100 server, type 8666, any model
  • A Netfinity 7000-M10 server, type 8680, any model
  • A Netfinity 7000 server, type 8651, any model
  • A Netfinity 6000R server, type 8682, any model
  • A Netfinity 5500-M20 server, type 8662, any model
  • A Netfinity 5500-M10 server, type 8661, any model
  • A Netfinity 5500 server, type 8660, any model
  • A Netfinity 5000 server, type 8659, any model
  • A Netfinity 4500R server, type 8656, any model
  • A Netfinity 3500-M10 server, type 8655, any model
  • A Netfinity 3500 server, type 8644, any model
  • A Netfinity 3000 server, type 8476, any model
  • A Netfinity 1000 server, type 8477, any model

The system may be any of the following IBM PC Servers:

  • A PC Server 300, type 8640, any model

Solution

If you are using PC100 SDRAM modules in a system with 100 MHz FSB (Front Side Bus), it is possible that you can get a FRU or option that is labeled as a PC133 SDRAM module by the supplier; this is okay as long as it is a valid IBM FRU/option number for that system.
 
NOTE: Systems with 100 MHz FSB (Front Side Bus) are listed in the "Affected configurations" section of this document.
