Installing Additional Memory 
Server memory can be expanded by installing Double Data Rate Synchronous 
DRAM (DDR SDRAM). The system supports up to four PC2100 ECC registered 
DDR SDRAM Dual Inline Memory Modules (DIMMs) installed in four sockets on 
the system board. Memory can be added one module at a time.  
Refer to Figure 3-4 and to Table 3-1 for DIMM slot location and socket numbers. 
This information is also available on the hood label. 
The server memory can be expanded to 4 GB. In the maximum memory 
configuration, all four DIMM sockets are populated with 1-GB, PC2100 ECC 
registered DDR SDRAM DIMMs. 
Observe the following guidelines when installing additional memory: 
• 
• 
• 
• 
• 
DIMMs installed in the server must be PC2100 registered DDR SDRAM, 2.5 V, 
64 bits wide, and ECC. 
All DIMMs installed must be the same speed. Do not install DIMM modules 
supporting different speeds, for example, 266 MHz and 200 MHz. 
Install the DIMMs in descending sequential order, starting with DIMM socket 4. 
Use only HP recommended DIMMs. DIMMs from other sources can adversely 
affect data integrity 
Use only the 3.05 cm (1.2 inch) DIMMs.
