AMD Makes A Compelling Case For Budget-Friendly Ryzen Dedicated Servers

The ASRock Rack 1U4LW-X570/2L2T server arrived with the Ryzen 9 5950X processor, 4 x 32GB ECC M4CE-BGS2MC0M-A DIMMs, and a Innodisk M.2 3TE6 NVMe solid-state drive.

When testing across CPUFreq governors, the reported Ryzen 9 5950X package power consumption reported by RAPL topped out at 148 Watt under load. The idle CPU power draw was around 25 Watts on this server or with the schedutil governor did hit 20 Watts. Unfortunately no overall system power consumption numbers due to this ASRockRack motherboard not exposing a system power consumption metric via ipmitool and the WattsUp Pro external power meter no longer working with the latest Linux kernels due to some USB serial driver regression.

The Ryzen 9 5950X with this ASRock Rack server was successfully hitting 4.9~5.0GHz under various server workloads. The average CPU frequency during sustaining a mix of single and multi-threaded workloads was around 4.3GHz.

The ASRock Rack 1U4LW-X570/2L2T was able to effectively cool this top-end Ryzen 9 5950X processor. Under load the average core temperature for the Ryzen 9 5950X within this 1U server was 66~68 degrees with a peak seen of 89 degrees.

The other thermal sensors were all at reasonable temperatures too for the environment.
