Systems With More Than 2 GB of
Memory and a RAID Controller
If your Dell PowerEdge 6100 system has more than 2 GB
of memory and a Dell PowerEdge Expandable RAID
controller, you must have the following to perform the
memory upgrade:
•
System: BIOS version A06 or later
•
Controller: Firmware version U.77 or later
If you have an earlier version of the BIOS, contact Dell
for an upgrade. (See the chapter titled "Getting Help" in
the Dell PowerEdge 6100/200 System Installation and
Troubleshooting Guide.)
Refer to the Dell PowerEdge Expandable RAID control-
ler documentation for more information.
DIMM Installation Guidelines
When installing DIMMs, populate the DIMM sockets
from J2 through J33 consecutively, using groups of four
DIMMs. For example, you must install the first four
DIMMs in sockets J2, J3, J4 and J5 (see Figure 1 for
socket locations).
CAUTION: Handle DIMMs carefully. Hold them
only by their edges. Do not slide them across any
surface. Applying too much pressure on retaining
clips can break the clips or damage the socket.
The 4-GB memory module supports error detection and
correction, memory downsizing, and address-bit permut-
ing. All configurations result in four-way interleaving.
The total memory reported by the system will be 32 MB
less than the actual memory installed. For example, if
your system has 4 GB of memory, it will report 4064 MB
instead of 4096 MB. The top 32 MB is reserved for the
basic input/output system (BIOS), Peripheral Component
Interconnect (PCI) devices, and event log area.
