1U rack server for general workloads

The Lenovo ThinkSystem SR645 7D2XA04GNA is a 1U rack server built around a single AMD EPYC 7282 processor running at 2.40 GHz. It ships with 32 GB of TruDDR4 memory and a Matrox G200 graphics controller. Eight small-form-factor drive bays provide internal storage capacity. A 750 W power supply and slide rails are included.

Suits single-socket deployments.

This configuration fits workloads that run on one processor and up to 32 GB of memory. The chassis supports a second EPYC processor and up to 4 TB of memory across 32 slots, so capacity can grow. Buyers who need two CPUs installed immediately or who require GPU compute acceleration should look at a different system. The Matrox G200 is intended for management display only.

Single AMD EPYC 7282 at 2.40 GHz with 32 GB TruDDR4

The decisive specification is the installed processor: one AMD EPYC 7282 at 2.40 GHz paired with 32 GB of TruDDR4 memory. This defines the baseline compute and memory available before any upgrades. The server supports a second processor and up to 4 TB of memory, but the shipping configuration determines whether the unit meets immediate performance requirements.

Questions about this item

How much rack depth does the 1U SR645 require for the slide rails?

The server is 30.4 inches deep; allow several extra inches behind the rear panel for cable management and airflow when mounting the included slide rail kit.

What is the first step when installing the AMD EPYC 7282 processor into the second CPU socket?

Remove the socket protective cover, align the triangle marker on the processor with the socket key, lower the chip gently, then secure the retention lever before applying thermal paste and the heatsink.

Which memory modules are compatible for expanding the 32 GB TruDDR4 beyond the 32 installed slots?

Use Lenovo-qualified TruDDR4 RDIMMs or 3DS RDIMMs up to the 4 TB maximum; populate slots per the memory population guide to maintain correct channel interleaving.
