Intel®
Server Board S1200BT TPS Functional Architecture
Revision 2.4 Intel order number G13326-007
For Intel® Xeon® E3-1200 V2 Processors or the 3rd Generation Intel® Core™ i3
Processors, the DIMM speeds of 1333/1600 MT/s (megatransfers/second).
Only Unregistered (Unbuffered) DIMMs (UDIMMs) are supported.
Only Error Correction Code (ECC) enabled DIMMs are supported.
UDIMMs may or may not have thermal sensors.
Note: UDIMMs must be ECC, and may or may not have thermal sensors.
S1200BT BIOS has the following limitations:
No support for LV DIMMs
No support for RDIMMs
All channels in a system will run at the fastest common frequency
Mixing ECC and non-ECC UDIMMs anywhere on the platform is not supported
Static Closed Loop Thermal Throttling (CLTT) supported through BMC (requires ECC
DIMMs with thermal sensor)
3.2.2 Post Error Codes
The range {0xE0 - 0xEF} of POST codes is used for memory errors in early POST. In late POST,
this same range of POST code values is used for reporting other system errors.
0xE8 - No Usable Memory Error: If no usable memory is available, the BIOS emits a
beep code and displays POST Diagnostic LED code 0xE8 and halts the system.
This can also occur if all memory in the system fails and/or has become disabled during
memory initialization. For example, if a DDR3 DIMM has no SPD information, the BIOS
treats the DIMM slot as if no DDR3 DIMM is present on it. Therefore, if this is the only
DDR3 DIMM installed in the system, there is no usable memory, and the BIOS goes to a
memory error code 0xE8 as described above.
0x53/0x55/0XE8 – DIMM SPD does not respond or DIMM SPD Read Error, the DIMM
will not be detected, if the SPD does not respond, which could result in “No memory
Installed” or “No Usable Memory” Memory Error Halt 0X53, 0x55, or 0xE8, or could
result later in an invalid configuration if the “no SPD” DIMM is in Slot 1 on the channel..
0x51 – Memory SPD Error: If the DIMM does respond but the SPD cannot be
successfully read, that would cause a “Memory SPD Error”, memory error halt 0X51. For
each memory channel, once the DIMM SPD parameters have been read, they are
checked to verify that the DIMMs on the channel are a valid configuration, DIMM speed
and size, ECC capability, and in which memory slots the DIMMs are installed. An invalid
configuration will cause the system to halt.
0xEA - Channel Training Error: If the memory initialization process is unable to
properly perform the Data/Data Strobe timing training on a memory channel, the BIOS
emits a beep code and displays POST Diagnostic LED code 0xEA momentarily during
the beeping. If there is usable memory in the system on other channels, POST memory
initialization continues. Otherwise, the system beeps and halts with POST Diagnostic
LED code 0xEA staying displayed.
0x54/0xEB - Memory Test Error: If a DDR3 DIMM or a set of DDR3 DIMMs on the
same memory channel fails memory testing but usable memory remains available, the
BIOS emits a beep code and displays POST Diagnostic LED code 0xEB momentarily
