1U rack server for scale-out compute

The Lenovo ThinkSystem SR645 is a single-socket 1U rack server built around one AMD EPYC 7262 processor running at 3.20 GHz. It ships with 16 GB of memory and a 25 Gigabit Ethernet connection. A single 750 W power supply and hot-swappable drive bays complete the configuration for dense deployment.

Suited for single-threaded cloud workloads

This system suits workloads that benefit from high per-core frequency on a single processor, such as web serving or virtual desktop infrastructure. Buyers who need dual-processor performance or larger memory capacity from day one should evaluate other platforms.

One EPYC 7262 at 3.20 GHz decides fit

The installed CPU is an 8-core EPYC 7262 with a 3.20 GHz base clock, setting the performance ceiling for the node. Adding a second processor later is possible, but the starting point is defined by this single chip.

Questions about this item

How do I install a second AMD EPYC processor into the SR645's empty Socket SP3?

Power down, open the chassis, remove the socket cover, align the new EPYC 7002 series CPU with the Socket SP3 keying, seat it, apply thermal paste, attach the heatsink, then power on and verify both CPUs in BIOS.

When will the 16 GB of installed memory need expansion for typical workloads?

Add DIMMs when applications exceed the 16 GB baseline; the SR645 supports additional memory modules to match the EPYC 7262's eight-channel architecture for balanced bandwidth.

At what point does the single 750 W power supply become the limiting factor during sustained loads?

The 750 W unit caps total draw; sustained CPU, memory, and 25 GbE network utilisation will hit that ceiling before thermal limits on the 1U chassis.
