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.
Refer to the Computer Setup (F10) Utility Guide for information on
how to determine the processor bus frequency of a specific computer.
