Processor Data Sheet
Table 2.
DRAM Interface Speed vs. CPU Core Clock Multiplier
The MEMCKE_LO/UP pins remain Low until the BIOS has forced an initialization process by
writing to the memory controller
s configuration registers. The DRAM initialization process involves
sending NOP cycles and writing to the Mode registers in the DRAM devices to force proper
configuration of the devices, as specified by JEDEC and device manufacturer
s specifications.
Table 3 on page 18 lists the maximum memory sizes per chip-select for the various supported DRAM
device configurations. Note that for DIMMs using two chip-selects, the total memory size per DIMM
is doubled. Refer to the
AMD Opteron
Processor Motherboard Design Guide
, order# 25180, for
details on the connection scheme for registered DIMMs in an AMD Opteron
processor system.
