Information Update This document provides updated information for your system. Memory Module Support 800-MHz Memory Modules 800-MHz memory modules are not supported at this time. If installed, the system will down-clock the memory modules to either 667 MHz or 533 MHz, depending on the processor installed: • For AMD™ Opteron™ quad-core processors (Family 10h), the 800-MHz memory modules will be down-clocked to 667 MHz if four or fewer memory modules are installed per processor. If more than four memory modules are installed per processor, the memory modules will be down-clocked to 533 MHz. • For AMD Opteron dual-core processors (Family 0Fh), the 800-MHz memory modules will be down-clocked to 667 MHz. Support for configurations of up to four 800-MHz memory modules per processor will be added at a future date. At that time, an updated BIOS adding this support will be available for download from support.dell.com. 8-GB Memory Modules 8-GB memory modules are not supported at this time. Support for 8-GB memory modules will be added at a future date. At that time, an updated BIOS adding this support will be available for download from support.dell.com. System Setup Program Updates The following items update "Using the System Setup Program" in your Hardware Owner's Manual: • The Low Power Mode option on the Memory Information Screen is not supported at this time. • On the CPU Information screen, the default setting for the Demand-Based Power Management option is Enabled.
