2-4 Installing RIMMs
CAUTION
Exercise extreme care when installing or removing RIMM
modules to prevent any possible damage.
Note: Check the Supermicro web site for a list of recommended memory
modules:

RIMM Installation (See Figures 2-2 and 2-3)
1.
Insert a pair of RDRAM modules (of the same type and size) into the
two RIMM slots of Bank 0. If needed, insert another pair of RDRAMs
(of the same type and size) into both slots of Bank1. If you populate
only the two slots of Bank0, then you need to populate both slots of
Bank1with "Continuity Modules" to close the signal loop. See
"RAMBUS Support" below for details on supported memory.
2. Insert each RDRAM module vertically into its slot. Pay attention to the
two notches along the bottom of the module to prevent inserting the
module incorrectly.
3. Gently press down on the RDRAM module until it snaps into place.
4. The P4DC6/P4DC6+/P4DC6+II/P4DCE/P4DCE+/P4DCE+II will support two
(2) or four (4) 600 or 800 MHz 184-pin RDRAM modules for a total of
up to 2 GB of system memory. Both ECC (Error Checking Correction)
and Parity Checking are supported.
RAMBUS Support (Important!)
The Memory Controller Hub (MCH) enables the use of RAMBUS in the
RIMM slots on the P4DC6/P4DC6+/P4DC6+II/P4DCE/P4DCE+/P4DCE+II. This
hub supports both ECC and non-ECC type memory, but you cannot mix both
types. (Check the Memory ECC Mode BIOS setting to enable the use of
ECC. See Section 1-2 for more on the MCH.)
