Product Notes

• Single rank or Dual rank memory is not an issue in this system because there is only four memory slots.
• The minimum memory configuration is one DIMM, installed in the DIMM 1B socket (the socket farthest from the CPU sockets). However, for optimum performance and dual-channel interleave operation, a minimum of two DIMMs should be installed. DIMMs on channel A (DIMM 1A and 2A) are paired with DIMMs on channel B (DIMM 1B and 2B) to enable 2-way interleaving.
• Populate both DIMMs in bank 1 (DIMM 1B and 1A) first, before populating DIMMs in bank 2 (DIMM 2B and 2A). Bank 2 must be populated in pairs.
• For the system to function, DIMM modules must be installed or removed in matched pairs, following the socket sequence :DIMM 1B and 1A first, then DIMM 2B and 2A. DIMM modules of the same type, banking, stacking technology, and manufacturer must be installed in the Altos G530 system.
• Altos G530 supports memory sparing function. To provide a more fault tolerant system, Altos G530 includes special hardware to support fail-over to a spare DIMM device in the event that a primary DIMM in use exceeds a specified threshold of runtime errors. One of the DIMMs installed per channel will not be used, but kept in reserve. In the event of significant failures in a particular DIMM, it and its corresponding partner in the other channel (if applicable), will, over time, have its data copied over to the spare DIMM held in reserve. When all the data has been copied, the reserved DIMM will be put into service and the failed DIMM will be removed from service. Only one sparing cycle is supported. If the memory sparing feature is not enabled, then all DIMMs will be visible in normal address space. Refer to Memory Configuration on page 101 for more information about configuring the memory spare parameter in the BIOS Setup Utility.
