128 GB — 16 x 8-GB quad-rank memory modules

•

256 GB — 32 x 8-GB quad-rank memory modules

NOTE:

Prior to upgrading your system, verify that the latest system BIOS version is on

your system. Loading the latest BIOS version from support.dell.com will ensure that

your system is fully supported.

NOTE:

Some operating systems cannot support more than 4 GB of physical memory.

For more information on memory support requirements and restrictions, refer to the

operating system documentation that ships with your system.

BMC and DRAC5 Firmware Version Requirements

When upgrading either the BMC or the DRAC5, you must update the firmware

for both components to ensure full functionality and compatibility.

For example, the power reduction feature of the DRAC5 version 1.40 firmware

works only when BMC 2.27 or higher is also installed. If the BMC and DRAC

firmware are incompatible—BMC 2.27 installed with DRAC5 version 1.33 or

BMC 1.79 installed with DRAC5 version 1.40—the power reduction feature may

not function correctly.

Page 2 Back Cooling Fans Systems manufactured after September 2008 no longer include the four back cooling fans installed in earlier systems. Therefore, BMC version 2.27 does not recognize the presence of back fans. The back fans will still run in older systems; however, from a system perspective, the fans do not exist and are not monitored.
