Installing Hardware Options Standard Memory Configurations You can expand server memory to 12 GB. In the maximum standard memory configuration, all six DIMM slots are populated with 2-GB ECC registered DDR DIMMs. NOTE: With Advanced ECC protection, the server can detect and correct four-bit errors in a single DRAM DIMM. Online Spare Memory Configurations With online spare memory support, you can configure primary server memory for up to 8 GB of ECC DDR memory and configure an additional 4 GB of memory for online spare memory support. In the online spare memory configuration, all six DIMM slots are populated with 2-GB ECC registered DDR DIMMs. In the online spare configuration, the ROM will automatically configure the last populated bank as the spare memory. If only banks A and B are populated, bank B will be the spare bank. If banks A, B, and C are populated, bank C will be the spare bank. If DIMMs in a non-spare bank exceed the limit for the single-bit correctable errors threshold as defined by the Pre-Failure Warranty, the system copies the memory contents of the failing bank to the spare bank. The system then deactivates the failing bank and automatically switches over to the redundant bank. After installing DIMMs, use RBSU to configure the system for online spare memory support. Refer to "Configuring Online Spare Memory" in Chapter 7 for additional information about enabling and configuring online spare memory support. IMPORTANT: For online spare memory configurations, adhere to the guidelines for both standard ECC and online spare DIMM installation. Refer to the sections "Standard ECC DIMM Installation Guidelines" and "Online Spare DIMM Installation Guidelines." Standard ECC DIMM Installation Guidelines You must observe the following guidelines when installing additional memory: • Always install memory in pairs of two identical DIMMs. • DIMMs installed in the server must be registered DDR, 2.5-volts, 72-bits wide, and ECC. 3-34 HP ProLiant ML370 Generation 3 Server Setup and Installation Guide
