Supported Memory Configuration - Intel BB5520UR Technical Product Specification

Functional Architecture
14. The minimal population upgrade recommended for enabling CPU 2 socket are
DIMM_A1 and DIMM_D1. This configuration supports only the Independent Channel
mode.
15. In the Mirrored Channel mode, memory population on Channels A and B should be
identical, including across adjacent slots on the channels, memory population on
Channels D and E should be identical, including across adjacent slots on the channels.
The DIMMs on successive slots are not required to be identical and can have different
sizes and/or timings, but the overall channel timing reduces according to the slowest
DIMM. If Channels A and B are not identical, or Channels D and E are not identical, the
BIOS selects default Independent Channel Mode.
16. If Channel C or F is not empty, the BIOS disables the Mirrored Channel Mode.
17. When only CPU1 socket is populated, minimal population upgrade for Mirrored Channel
Mode are DIMM_A1 and DIMM_B1. DIMM_A1 and DIMM_B1 must be identical,
otherwise, they will revert to Independent Channel Mode.
18. When both CPU sockets are populated, minimal population upgrade for the Mirrored
Channel Mode are DIMM_A1, DIMM_B1, DIMM_D1 and DIMM_E1. DIMM_A1 and
DIMM_B1 as a pair must be identical, and so must DIMM_D1 and DIMM_E1 as a pair.
The DIMMs on different CPU sockets need not be identical in size and/or sizing,
although overall channel timing reduces according to the slowest DIMM.

Supported Memory Configuration

3.3.10.1 Supported Memory Configurations
The following sections describe the memory configurations supported and validated on the
®
Intel Server Boards S5520HC, S5500HCV and S5520HCT.
3.3.10.1.1 Levels of support
The following categories of memory configurations are supported:
Supported – These configurations were verified by Intel to work but only limited
validation was performed. Not all possible DDR3 DIMM configurations were validated
due to the large number of possible configuration combinations. Supported
configurations are highlighted in light gray in Tables 5 and 6.
Validated – These configurations have received broad validation by Intel. Intel can
provide customers with information on specific configurations that were validated.
Validated configurations are highlighted in dark gray in Tables 5 and 6.
All populated DIMMs are identical.
The following is a description of the columns in Tables 5 and 6:
X – Indicates the DIMM is populated.
M – Indicates whether the configuration supports the Mirrored Channel mode of
operation. It is one of the following: Y indicating Yes; N indicating No.
N – Identifies the total number of DIMMs that constitute the given configuration.
