• If your system does not have the Roman numeral "II" label, it requires CPLD, BIOS, and iDRAC firmware upgrade to support Intel Xeon processor E7-2800/4800/8800 product family. You can download the CPLD, BIOS, and iDRAC firmware at support.dell.com. NOTE: Update the BIOS with 7500 series installed before replacing with Intel Xeon processor E7-2800/4800/8800 product family. Low Voltage Memory Modules (DDR3L DIMMs) DDR3L RDIMMs enable a lower operating voltage (1.35 V) and save up to 20 percent of memory power per RDIMM. The following are required to support DDR3L RDIMMs at 1.35 V: • Intel Xeon processor E7-2800/4800/8800 product family • Memory riser (PowerEdge R910 II) marked with the Roman Numeral "II" or system board (PowerEdge R810/M910 II) with Intel 7510 scalable memory buffer. Supported DDR3L are 2 GB x8, 4 GB x8, 8 GB x8, and 16 GB x4 DRAM RDIMMs. NOTE: RDIMMs rated at 1333 MT/s operate at maximum of 1066 MT/s. • PowerEdge R810 supports four 130 W Intel Xeon processor E7-4800/8800 product family only with DDR3L at 1.35 V. • PowerEdge R910 memory riser board marked with the Roman numeral "II" supports DDR3L RDIMMs. • PowerEdge R910 does not support mixing memory risers with and without the Roman numeral "II". • 32 GB x4, 4 Gb DRAM, DDR3L RDIMMs are supported on PowerEdge R910 with Intel Xeon processor E7-2800/4800/8800 product family and memory riser board marked with the Roman numeral "II". 6 Information Update
