Make the Right Memory Choices for Your Server
Workload consolidation, adding AI capacity, enhancing power efficiency, improving uptime, and meeting security demands are enabled by server refreshes, but today’s memory-constrained environment can make server modernization plans seem challenging. Right-sizing memory requirements is the path forward to help keep your data center updated while delivering business value, despite market constraints.
More Isn’t Always Better: Rethinking Memory Choices for Modern Workloads
Right-size with AMD EPYC™ Server CPUs to enable better optimization of performance, cost, and power by focusing on the right memory-per-core balance rather than maximum memory capacity.
Refreshing Your Server in a Memory-Constrained Market
A server refresh can help you add capacity, improve uptime, meet security requirements, and consolidate, ultimately improving energy efficiency and total cost of ownership (TCO). Alternatively, delaying IT modernization can increase your costs in the long run.
Here’s how you can help keep your server refreshes on track, even in a memory-constrained market:
Audit Your Environment
Managing a constrained market requires data – and that means knowing what you have and what you really need.
Identify Memory-Sensitive Workloads
Not all workloads need vast quantities of memory. Understand the impact of memory sensitivity on workloads.
Right-Size Your Memory Provisioning
With 12-channels of memory, AMD EPYC Server CPUs provide flexibility to meet memory capacity, performance and cost needs.
Frequently Asked Questions
Not necessarily. While some are experiencing challenges in securing affordable server memory configurations, waiting out an unpredictable market is not a viable enterprise IT strategy. A data center refresh is not a memory decision alone, and there are easily adoptable strategies for mitigating the impact of increased cost of server configurations.
Not necessarily. AMD provides a robust, high-bandwidth 12 channel per processor memory subsystem capable of supporting the most demanding workloads. This memory subsystem also provides tremendous flexibility through a broad set of memory configuration/population options to meet a broad array of workload performance, capacity and cost needs.
Not necessarily. While this is something of a “rule of thumb” in the IT world, data tells a different story. AMD and 3rd party testing shows that for select compute-intensive workloads, once a minimal threshold of memory/core is provisioned, additional capacity and/or bandwidth provide little or no incremental performance benefit. As is often the case, understanding specific workload needs is useful.
In general, no. DDR4 memory modules used in older EPYC 7003, or Intel “Ice Lake” Xeon server systems are not electrically or mechanically compatible with the DDR5 sockets of the EPYC 9004 or EPYC 9005 CPUs. Depending on your server vendor’s validated and approved accessories lists, it may be possible to deploy the older DDR4 modules into CXL®-based memory expansion boards and used in the newer systems. Note that while this provides additional memory capacity, performance will be degraded compared to DDR5.
