The MR9A Pro usually ships with Microcode 0x38 (Broadwell-EP) and 0x27 (Haswell-EP) revisions.
Stock BIOS versions often lock memory timings; custom BIOS versions "exclusively" restore access to adjust primary and secondary timings for better RAM performance.
This is perhaps the most sought-after "exclusive" mod. It allows Xeon E5 v3 processors to run at their maximum turbo frequency across all cores simultaneously, significantly boosting multi-threaded performance.
