Fujitsu D1241 manual System Memory Dimm, Sdram Configurations

3.HARDWARE SETUP

3.5System Memory (DIMM)

NOTE: No hardware or BIOS setup is required after adding or removing memory. This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are available for 3.3Volt (power level) “registered” Synchronous Dynamic Random Ac- cess Memory (SDRAM) of 64, 128, 256, 512, 1024MB with Serial Presence Detect (SPD). ECC memory modules must be used to provide reliability enhancements.

Memory speed setup is recommended through SDRAM Configuration in 4.4.1 Chip Configuration.

IMPORTANT: This motherboard’s chipset only supports 64Mbit, 128Mbit, and 256Mbit “registered” SDRAMs with ECC. This motherboard only operates using synchronous data transfers to the memory. When you use a processor with 100MHz FSB, it will require that the memory supports 100MHz. When you use a proces- sor with 133MHz FSB, it will require that the memory supports 133MHz or else bootup may not be possible.
