Frequently Asked Questions Q: What memory configurations are supported by the Gateway 9315 Server motherboard?A: The memory controller is capable of supporting up to four loads per channel for DDR-333. Memory technologies are classified as being either single rank or dual rank depending on the number of DRAM devices that are used on any one DIMM. A single rank DIMM is a single load device, i.e. Single Rank= 1 load. Dual rank DIMMs are dual load devices, i.e. Dual Rank = 2 loads.
The 9315 server motherboard provides the following maximum memory capacities based on the number of DIMM slots provided and the maximum supported memory loads by the chipset:
The minimum memory supported with the system running in single channel memory mode is:
Supported DIMM capacities are as follows:
The following table provides DIMM module capacities.
DIMMs on Channel "A" are paired with DIMMs on channel "B" to configure 2-way interleaving. Each DIMM pair is referred to as a bank. The bank can be further divided into two tows, based on single-sided or double-sided DIMMs. If both DIMMs in a bank are single-sided, only one row is said to be present. For double-sided DIMMs, both rows are said to the present.
The 9315 server motherboard has six DIMM slots, or three DIMM banks. Both DIMMs in a bank need to be identical (same manufacturer, CAS latency, number or rows, columns, and devices, timing parameters, and so on). Although DIMMs within a bank must be identical, the BIOS supports various DIMM sizes and configuration allowing the banks of memory to be different.
