A DDR3 module is notched differently from a DDR or DDR2 module. DO NOT install a DDR or DDR2 memory module to the DDR3 slot. DIMM_A1 DIMM_B1 According to Intel® CPU spec, DIMM voltage below 1.65V is recommended to protect the CPU. Channel Sockets Channel A DIMM_A1 Channel B DIMM_B1 H81M-E R2.
1.4.2 Memory configurations You may install 1GB, 2GB, 4GB, and 8GB unbuffered non‑ECC DDR3 DIMMs into the DIMM sockets. 1.4.3 • You may install varying memory sizes in Channel A and Channel B. The system maps the total size of the lower-sized channel for the dual-channel configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation.
2 3 To remove a DIMM B A A 1.5 Expansion slots In the future, you may need to install expansion cards. The following sub‑sections describe the slots and the expansion cards that they support. Unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components. ASUS H81M-E R2.
