At a glance

This DIMM offering lets you upgrade standard system memory capacity, improving overall system performance. Features and benefits include:

• Guaranteed compatibility on systems indicated in the "Hardware Requirements" section
• Meets or exceeds reliability standards for memory products
• Fast access time -- synchronous to processor's front-side bus clock
• 168-pin DIMM with gold-plated leads
• Serial presence detect/decode functions

Overview

Improve the overall performance of your eServer xServer and Netfinity systems with the following new memory upgrades:

• IBM 128MB, 256MB, 512MB and 1GB PC133 ECC Synchronous Dynamic Random Access Memory (SDRAM) Registered DIMM (RDIMM) Memory
• IBM 128MB, 256MB and 512MB PC133 ECC SDRAM RDIMM Memory

SDRAM enables faster performance than either traditional fast page mode (FPM) or hyper-page mode (EDO) memory.

Adding additional IBM Memory is a cost-effective way to improve your system's performance.
