Server Board S2400EP TPS
Intel order number G50763-002 Revision 2.0
24
o LRDIMM DDR3 – QR – x4 and x8 data widths with direct map or with rank
multiplication
Up to 8 ranks supported per memory channel, 1, 2 or 4 ranks per DIMM
Open with adaptive idle page close timer or closed page policy
Per channel memory test and initialization engine can initialize DRAM to all logical zeros
with valid ECC (with or without data scrambler) or a predefined test pattern
Isochronous access support for Quality of Service (QoS)
Minimum memory configuration: independent channel support with 1 DIMM populated
Integrated dual SMBus* master controllers
Command launch modes of 1n/2n
RAS Support:
o Rank Level Sparing and Device Tagging
o Demand and Patrol Scrubbing
o DRAM Single Device Data Correction (SDDC) for any single x4 or x8
DRAM device. Independent channel mode supports x4 SDDC. x8 SDDC
requires lockstep mode
o Lockstep mode where channels 0 and 1 and channels 2 and 3 are
operated in lockstep mode
o Data scrambling with address to ease detection of write errors to an
incorrect address.
o Error reporting via Machine Check Architecture
o Read Retry during CRC error handling checks by iMC
o Channel mirroring within a socket
- CPU1 Channel Mirror Pairs B and C
- CPU2 Channel Mirror Pairs E and F
o Error Containment Recovery
Improved Thermal Throttling with dynamic Closed Loop Thermal Throttling (CLTT)
Memory thermal monitoring support for DIMM temperature
