In the Independent Channel mode, all DDR3 channels operate independently. Slot-to-slot DIMM
matching is not required across channels (for example, A1 and B1 do not have to match each
other in terms of size, organization, and timing). DIMMs within a channel do not have to match
in terms of size and organization, but they operate in the minimal common frequency. Also,
Independent Channel mode can be used to support single DIMM configuration in channel A and
in the Single Channel mode.
You must observe the following general rules when selecting and configuring memory to obtain
the best performance from the system.
1. DDR3 RDIMMs must always be populated using a fill-farthest method.
2. DDR3 UDIMMs must always be populated on DIMM A1/A2/B1/B2.

3. Intel Xeon

4. Intel Xeon
Processor G6950 only support UDIMMs.
5. RDIMM and UDIMM CAN NOT be mixed.
6. The minimal memory set is {DIMMA1}.
7. DDR3 DIMMs on adjacent slots on the same channel do not need to be identical.
Each socket supports a maximum of six slots. Standard Intel
®
use the Intel 3420 chipset support three slots per DDR3 channel, two DDR3 channels per
socket, and only one socket is supported on the Intel
