In some cases, an issue has been noted, concerning CPU frequency on overclocked Game MC-64 servers. It occurs that the frequency setting in the BIOS goes back to the default configuration. In this case the overclocking profile is not applied and the CPU frequency is capped at a maximum of 4 Ghz.
We are working on the root cause. If you notice on your server that the CPU frequency does not exceed 4 GHz under full load, we ask that you open a support ticket in order to correct the situation
