Working with system memory You can add memory to your server to increase system performance. Your server has four connectors for installing system-memory modules (DIMMs) up to a maximum of 1 GB. Memory DIMM options: Important: Be sure to observe the following guidelines when adding memory DIMM options to your server. Only 168-pin, 100 MHz, 3.3V industry standard memory DIMMs are supported. Do not mix registered and unregistered DIMMs. - The 64 MB and 128 MB DIMMs are unregistered memory technology. - The 256 MB DIMM is registered memory technology. The Netfinity 3500 M10 does not support EDO memory. If you use registered DIMMs, you must remove all unregistered DIMMs from your server. A mix of registered and unregistered memory prevents the server from completing startup, and results in an error beep sequence and a blank screen. Note To locate the DIMM connectors inside your server, see "Identifying parts on the system board" on page 80. 1 2 3 4 84 Netfinity Server HMM
