Upgrading Memory

The following sections discuss supported memory for A–Series blades and describe how to
install memory.

A1410 Configurations

The A1410 PC blade uses the Intel® Q965 Express chipset and supports DDR2 800, DDR2
667, and DDR2 533 MHz DIMMs for the following memory maximums:
• 8 GB system memory—using DDR2 667 or 533 DIMMs
• 4 GB system memory—using DDR2 800 DIMMs
The A1410 contains four memory sockets that accept 240-pin DDR2 SDRAM. A1410
memory sockets are color-coded:
• Blue sockets—DIMM 0
• Black sockets—DIMM 1
Memory is organized in two pairs of sockets, as shown in
operate in Interleaved, Asymmetric, or Flex modes depending on the memory capacity and
channel configuration that you use.
• Dual channel (Interleaved) mode—Offers highest throughput. Dual channel mode is
enabled when the DIMMs installed in both channels are equal in density, speed, and
latency (using DIMMs from the same manufacturer helps to ensure that you are using
matching DIMMs). If channels A and B contain DIMMs of different speeds, the slowest
speed is used.
• Single channel (Asymmetric) mode—Used when a single DIMM is installed or when
multiple DIMMs are installed and their memory capacities are unequal. If channels A and
B contain DIMMs of different speeds, the slowest speed is used.
• Flex mode—Offers multiple areas of dual and single channel operation over the entire
DRAM memory. In flex mode:
–
–
You must populate both channels to use flex mode.

A1010 Configurations

The A–Series blade features four 184-pin Double Data Rate (DDR) Dual Inline Memory
Modules (DIMM) sockets. Memory is organized in two pairs of sockets and can operate in
interleaved or non-interleaved memory mode.
A1010 memory channels are color–coded, as shown in
• Blue sockets—Channel A
• Black sockets—Channel B
Note:
Memory lowest in the system memory map operates in dual channel mode
Memory nearest the 8 GB address space limit, if any, operates in single channel mode
ClearCube recommends populating Channel A first.
