Memory Support
The HX2560 M1/HX2560 M2 supports up to 128 GB of registered, ECC DDR3-
1866/1600/1333/1066/800 MHz RDIMMs in 8 DIMM slots. See the following tables for
memory installation.
Notes: Memory speed support is dependent on the type of CPU used on the board.
Processor/DIMM Population Configurations
For memory to work properly, follow the tables below for memory installation.
•
For memory to operate properly, please install DIMMs in pairs (have an even number
of DIMMs installed).
•
All channels in a system will run at the fastest common frequency.

Population Rules:
1. Any combination of x4 and x8 RDIMMs with 1 Gb or 2 Gb DRAM density are supported.
2. Populate DIMMs starting with DIMM A1.
3. When mixing QR with SR or DR on the same DDR channel, put the QR in DIMMA1 first.
