when i export my RDTSC_FREQUENCY for running a source engine based server, should that value be the clock frequency or the turbo clock frequency of the cpu? ie. i'm currently on strongest single threaded cpu nfo offers. (e3 1270 v3)
the problem with this is thats the core clock frequency. could this be why the cpu is alwaying maxing out at a set value in 80%'s regardless of the cpu? i got the same result on a e5 2690 which is much weaker on a single threaded application like a source engine based server.
the export is working and all because it no longer runs the benchmark on startup. this is the same value as the automatic benchmark has given me multiple times.
The RDTSC frequency is a static value that the CPU chooses regardless of what mode it is in at the time. It is generally close to the default clock speed of the CPU. It is not tied to the realized performance of the CPU, which is why software can reliably use RDTSC for timing.
It's not a software value, no. It's provided by the hardware and static across all clock speeds that the processor can run at. There is only one value and you using anything different will not be helpful to you.
