Product Notes

• The Server Boards Altos G520 each provides four 266MHz / 333MHz DIMM sites in two DIMM banks. The maximum memory capacity is 8GB for either 266MHz or 333MHz memory. Memory DIMM technologies supported are: 128MB, 256MB, 512MB, 1 GB and 2 GB.
• The minimum memory configuration is one DIMM, installed in DIMM socket 1B (the socket farthest from the processors). However, for optimum performance and dual-channel interleave operation, a minimum of two DIMMs should be installed. DIMMs on channel A are paired with DIMMs on channel B to configure 2-way interleaving. Both DIMMS in Bank 1 (DIMM1B and DIMM1A) must be populated before any DIMMs are installed in Bank 2 (DIMM2B and DIMM2A). Bank 2 must be populated in pairs. Both DIMMs in a bank must be identical (same manufacturer, CAS latency, number of rows, columns and devices, timing parameters etc.). Although DIMMs within a bank must be identical, the BIOS supports various DIMM sizes and configurations allowing the banks of memory to be different.
• The mixing of 266MHz and 333MHz memory is supported on the Server Boards Altos G520. However, when mixing DIMM types, 333MHz will be treated as 266MHz.
