4.2 Processor
ATCA-7490 provides two Intel Xeon E5-26xxL V4 (Broadwell-EP) server processors as the
central processing unit (CPU). Each processor provides 40 PCIe lanes up to Gen3 speeds
(8GT/s). The processors are connected with each other through two Intel QuickPath
Interconnect point-to-point links capable of up to 9.8 GT/s. Each processor provides an
integrated 4-channel DDR4 Memory Controller (IMC) supporting up to DDR4-2400.
4.3 DDR4 Main Memory
The blade provides two CPUs which has four channels of independent DDR4 memory on each
CPU. On each of the eight DDR4 channels the blade provides two DIMM sockets. The Joint
Electron Device Engineering Council (JEDEC) specification defines a DDR4 socket with 288
pins. Registered DDR4 DIMMs are used for best performance.
The following are the DDR4 module specifications:

DDR4-2400

Very Low Profile

Max 2 ranks per DIMM

8, 16, and 32 GByte capacity

Standard Voltage (1.2V)
