512MB 100MHz ECC SDRAM RDIMM - Product Overview

Applicable to: World-Wide

General Information
You can improve your system's performance and speed with the 512MB 100MHz ECC Synchronous Dynamic Random Access Memory (SDRAM) Registered DIMM (RDIMM) upgrade. The SDRAM function allows the memory upgrade to perform faster than either traditional fast page mode (FPM) or extended data out (EDO) memory modes of operation. This ECC SDRAM RDIMM offers access times that are synchronous to the processor's system bus. This upgrade is compatible with the IBM IntelliStation Z Pro Machine Type 6865 systems. The memory can also be installed on non-IBM systems that support industry standard SDRAM RDIMMs to the PC-100 specification.

Limitations:

• Registered memory improves the signal quality necessary to support large-capacity DIMMs running at 100 MHz and can only operate properly with other registered DIMM (RDIMM) capacities. Your system will not operate properly if RDIMMs are mixed with either unbuffered or buffered DIMM memory modules.
• Some configurations may not be compatible.

Supported Software: Not Applicable
