Product Notes

• Per HP:
• The BL685c G7 has thirty-two (32) memory slots. There are four (4) channels per processor; sixteen (16) channels per server. There are two (2) DIMM slots for each memory channel; thirty-two (32) total slots.
• Memory channel 1 consists of the two (2) DIMMs that are furthest from the processor. Memory channel 4 consists of the two (2) DIMMs that are closest from the processor.
• A minimum of two (2) DIMMs per processor are required.
• DIMM slots that are white should be populated first.
• Do not install DIMMs if the corresponding processor is not installed.
• If only two (2) processors are installed in a four (4) CPU system, only half of the DIMM slots are available.
• To maximize performance, balance the total memory capacity between all installed processors.
• To maximize performance, balance the total memory capacity on any given processor across the memory channels.
• You may only have up to eight (8) ranks installed per channel.
• You may install up to two (2) quad-rank DIMMs per channel.
• If mixing DIMM voltage is a requirement, please note that the DIMMs will run at 1.5V since all 1.35V are capable of supporting 1.5V operations.
• When running virtualization software, a minimum of two (2) DIMMs per processor are required. Populate DIMM sockets 1A and 5B for each processor socket populated.
