Dell PowerEdge 1500SC - Manual (Page 37)

Installing the Microprocessor and Memory Module Cooling Shrouds
1. Lower the microprocessor cooling shroud into the chassis ensuring that the four securing tabs of the shroud is aligned with the holes in the back-panel
(see Figure 6 -7 ).
2. Press the cooling shroud down until it snaps into place securing the cooling shroud to the back-panel (see Figure 6 -7 ).
3. Insert the two tabs on the memory module shroud into the two slots on the microprocessor shroud and swing the memory module shroud down until it
snaps into place.
4. Replace the system's right-side cover.
5. Replace the front bezel.
Adding Memory
The memory modules are contained in four memory module sockets. The system can accommodate 128 MB to 4 GB of registered memory modules. The memory
module sockets are arranged in two pairs. PAIR 1 consists of DIMMA and DIMMB and PAIR 2 consists of DIMMC and DIMMD. Memory modules must be installed
in pairs and must be indentical (type and vendor).
Memory Upgrade Kits
The system is upgradable to 4 GB by installing combinations of 128- 256-, 512-MB, and 1 GB registered memory modules. If you receive an error message
stating that maximum memory has been exceeded, see "
Indicators, Messages, and Codes ," for detailed information. You can purchase memory upgrade kits
from Dell as needed.
Memory Module Installation Guidelines
Starting with the socket nearest the power connector, the memory module sockets are labeled "PAIR1 DIMMA and DIMMB" and "PAIR2 DIMMC and
DIMMD" (see
Figure 6 -8 ). When you install memory modules, follow these guidelines:
l You must install memory modules in indentical pairs.
l Install a pair of memory modules in sockets PAIR1 DIMMA and DIMMB before installing the second pair in sockets PAIR2 DIMMC and DIMMD.
l When memory modules are installed in both PAIR1 and PAIR2, install memory modules of the same size for optimum performance.

NOTE: The memory modules must be PC-133 compliant.
