3.1.2 Memory
The aTCA-6250 is a dual processor system with each Intel® Xeon® processor E5 providing
four memory channels supporting DDR3 800, 1066, 1333, and 1600 MT/s DIMMs. The
maximum memory capacity is 128GB with memory interleaving support. The 400/533/667/800
MHz differential memory clocks are driven by the Intel® Xeon® processor E5 CPU with
length-matching and impedance controlled through all the DIMM slots.
The next generation of Xeon® family CPU is code named Ivy Bridge-EP. Each Ivy Bridge-EP
provides four memory channels supporting DDR3 800, 1066, 1333, 1600 and 1866MT/s
DIMMs. The maximum memory capacity is 128GB with memory interleaving support. The
400/533/667/800/933 MHz differential memory clocks are driven by the Ivy Bridge-EP CPU
with length-matching and impedance controlled through all the DIMM slots.
The DDR3 DIMMs support the I
2 C interface. They are connected together and routed to the
PCH for the management.
Memory configuration changes are only permitted to be performed at the factory.
Failure to comply with the above may result in damage to your board or improper
operation.
