The benchmark with the largest performance impact from having ECC memory enabled was the demanding Graph500 HPC benchmark that is quite memory intensive.

GROMACS benchmark with settings of Implementation: MPI CPU, Input: water_GMX50_bare. ECC Disabled was the fastest.
PostgreSQL benchmark with settings of Scaling Factor: 1, Clients: 1000, Mode: Read Only. ECC Disabled was the fastest.
TensorFlow benchmark with settings of Device: CPU, Batch Size: 64, Model: ResNet-50. ECC Disabled was the fastest.
Blender benchmark with settings of Blend File: Classroom, Compute: CPU-Only. ECC was the fastest.
OpenVINO benchmark with settings of Model: Face Detection FP16-INT8, Device: CPU. ECC Disabled was the fastest.
Apache Hadoop benchmark with settings of Operation: Create, Threads: 20, Files: 100000. ECC Disabled was the fastest.
Apache Hadoop benchmark with settings of Operation: Delete, Threads: 20, Files: 100000. ECC Disabled was the fastest.
Apache Hadoop benchmark with settings of Operation: Create, Threads: 100, Files: 100000. ECC Disabled was the fastest.
