14 Intel® Server Board S1200BT Service Guide
Except for these two processors, the Intel
®
 Server Board S1200BT also supports the 
Intel
®
 Xeon
®
 E3-1200 V2 Processors or the 3
rd
 Generation Intel
®
 Core™ i3 Processors  
in FC-LGA 1155 socket package with 5GT/s point-to-point DMI interface to PCH and 
LGA 1155 pin socket. For a complete list of supported processors, see the links under 
“Additional Information and Software”.
Memory 
The Intel
®
 Server Board S1200BT supports a DDR3-based ECC UDIMM memory 
subsystem and up to two DIMM sockets per channel.
See the following figure for channel slot configuration. The minimal memory population 
is one DIMM in memory slot DIMM_A1. For a complete list of supported memory, see 
the links under “Additional Information and Software”
Table 4. Memory Configuration Table.
The Independent Channel Mode is the default Maximum Performance Mode preferred for 
Intel
®
 Xeon
®
 Processor E3-1200 Series based platforms. All two channels may be 
populated in any order and have no matching requirements. All channels must run at the 
same interface frequency, but individual channels may run at different DIMM timings 
(RAS latency, CAS latency, and so on).
