Hardware Reference 3
3.1 Power Requirements
The IQ80960RM/RN platform draws power from the PCI bus. The power requirements of the
IQ80960RM/RN platforms are shown in
Table 3-1 and Table 3-2 . The numbers do not include the
power required by a PCI card(s) mounted on one or more of the IQ80960RM/RN platforms’ four
expansion slots.
3.2 SDRAM
The IQ80960RM/RN platform is equipped with a 168-pin DIMM socket formatted to accept +3.3V
synchronous DRAM with or without Error Correction Code (ECC). The socket will accept SDRAM
from 8 Mbytes to 128 Mbytes. 128 Mbyte SDRAMs are available in both x64 and x72 configurations.
Note that 8 Mbyte SDRAMs are only for x64 or non-ECC memory. The SDRAM is accessible from
either of the PCI buses, via the ATUs, and the local bus on the IQ80960RM/RN platform.
