General Memory Module Installation Guidelines

NOTE: Memory configurations that fail to observe these guidelines can prevent your system from booting, hanging during memory configuration, or operating with reduced memory.

This system supports Flexible Memory Configuration, enabling the system to be configured and run in any valid chipset architectural configuration. The following are the recommended guidelines for best performance:

UDIMMs and RDIMMs must not be mixed.

x4 and x8 DRAM based DIMMs can be mixed. For more information, see Mode-Specific Guidelines.

A maximum of two UDIMMs can be populated in a channel.

A maximum of two single- or dual-rank RDIMMs can be populated in a channel.

Populate all sockets with white release tabs first, and then black.

Populate the sockets by highest rank count in the following order - first in sockets with white release levers, and then black. For example, if you want to mix quad-rank and dual-rank DIMMs, populate quad-rank DIMMs in the sockets with white release tabs and dual-rank DIMMs in the sockets with black release tabs.

Memory modules of different sizes can be mixed provided that other memory population rules are followed (for example, 2 GB and 4 GB memory modules can be mixed).

Depending on mode-specific guidelines, populate two or three DIMMs per processor (one DIMM per channel) at a time to maximize performance. For more information, see Mode-Specific Guidelines.

If memory modules with different speeds are installed, they will operate at the speed of the slowest installed memory module(s) or slower depending on system DIMM configuration.

Mode-Specific Guidelines

The allowable configurations depend on the memory mode selected.

NOTE: x4 and x8 DRAM based DIMMs can be mixed providing support for RAS features. However, all guidelines for specific RAS features must be followed. x4 DRAM based DIMMs retain Single Device Data Correction (SDDC) in either memory optimized (independent channel) or Advanced ECC modes. x8 DRAM based DIMMs require Advanced ECC mode to gain SDDC.

The following sections provide additional slot population guidelines for each mode.

Advanced ECC (Lockstep)

Advanced ECC mode extends SDDC from x4 DRAM based DIMMs to both x4 and x8 DRAMs. This protects against single DRAM chip failures during normal operation.

Memory sockets A1 and A4 are disabled and you can populate DIMMs in memory sockets A2, A3, A5, and A6.

NOTE: Advanced ECC with Mirroring is not supported.

Memory Optimized (Independent Channel) Mode

This mode supports SDDC only for memory modules that use x4 device width and does not impose any specific slot population requirements.

R320 specifications

The Dell PowerEdge R320 is a significant addition to the enterprise server lineup, capturing the needs of businesses that require efficiency, reliability, and scalability. Designed for a variety of applications, the R320 caters to both light virtualization and everyday workloads. Its compact 1U form factor makes it an optimal choice for space-constrained server environments.

One of the standout features of the R320 is its support for Intel Xeon E5-2400 processors, which deliver enhanced performance with up to eight cores per processor. This multi-core capability enables businesses to handle more tasks simultaneously, leading to improved overall productivity. The server supports up to two processors, allowing organizations to scale their compute power as needed.

Memory is another critical aspect where the R320 excels. It boasts 12 DIMM slots, allowing for a maximum memory capacity of 192 GB with 16 GB DDR3 memory modules. This high memory capacity ensures that the server can manage large datasets and perform demanding computations without bottlenecks.

The storage options in the R320 are versatile, with support for up to eight 2.5-inch hot-swappable drives, providing organizations the flexibility to configure storage according to their specific needs. The server supports both SAS and SATA drives, enabling users to choose between speed and capacity. This variety allows businesses to optimize their storage for both performance-oriented applications and large volume data storage.

Networking capabilities are robust, featuring integrated Broadcom NetXtreme II dual-port 1GbE network interface cards (NICs), which enhance connectivity and provide redundancy for mission-critical operations. For additional performance, users can upgrade the NICs to 10GbE options, ensuring that the R320 can handle future network demands.

The R320 also incorporates Dell’s innovative management features through the Integrated Dell Remote Access Controller (iDRAC). This technology allows administrators to monitor the server's health remotely and perform management tasks, reducing the need for physical access to the hardware and ensuring smooth operations.

In terms of energy efficiency, the R320 includes features such as power management settings and energy-efficient components designed to minimize power consumption without compromising performance. This aspect is increasingly important as organizations seek to reduce their carbon footprint and operational costs.

Overall, the Dell PowerEdge R320 is an impressive server that combines powerful processing capabilities, flexible storage options, and advanced management features, making it a suitable choice for a wide range of enterprise applications. Whether for small to medium-sized businesses or larger enterprises, the R320 delivers the performance, scalability, and reliability necessary for today's demanding workloads.
