Ddr-Sdram Dimms - HP d325 ST Hardware Reference Manual

DDR-SDRAM DIMMs

For proper system operation, the DIMMs must be industry-standard 184-pin 2.5 volt
DDR-SDRAM DIMMs with appropriate MHz-compliant CAS Latency:
unbuffered PC 2100 266-MHz compliant CAS Latency 2 or 2.5 (CL =2 or CL =2.5)
or
unbuffered PC 2700 333-MHz compliant CAS Latency 2.5 (CL = 2.5)
The DDR-SDRAM DIMMs must also contain the mandatory Joint Electronic Device
Engineering Council (JEDEC) Serial Presence Detect (SPD) information. DIMMs
constructed with x4 SDRAM are not supported; the system may not start using
unsupported DIMMs.
The computer memory will run at its rated frequency, unless that is faster than the
processor frequency. If the module frequency is faster, then the computer will run at
the processor frequency.

The PC1600 (200 MHz) and PC3200 (400 MHz) may work, but are not supported.
The system may not start using unsupported DIMMs.
