If you disable it you should be careful to only install system drivers It is important to note that the kext-signing setting is global, To use DisableTurboBoost, you need to disable the kext signing security

(A kext is a kernel extension, or a driver, in Mac OS X). In OS X 10.10 (Yosemite), Apple has introduced a new security requirement called

MSRs Supported by Intel Processors Based on Intel Microarchitecture Code Name Sandy Bridge (Contd.) - Intel® 64 and IA-32 Architectures Software Developer’s Manual Volume 3C Prerequisites This program implements modification of MSR CPU register responsible for Turbo Boost control as described in Table 34-10.

for 4 core i5 CPU OpenMP program running on all 4 cores is only ~3x faster than 1 single core version.ĭisabling Turbo Boost makes CPU run same clock regardless of cores occupation, therefore we get desired close to 4x speedup when running 4 cores OpenMP program vs 1 core. As a result parallel tasks performance running on all CPU cores does not scale relatively to number of cores, i.e.

However when all CPU cores are occupied, Turbo Boost doesn't trigger as it would cause CPU overheat.

Unfortunately it has nasty effect of ruining various OpenCL and OpenMP benchmark scores.Īs observed Turbo Boost triggers when process is occupying 100% of single CPU core, while other CPU cores are idle. Turbo Boost technology provides automatic CPU over-clocking in certain situations where there is no risk of overheating the CPU.

This kernel extension DisableTurboBoost.kext lets you disable Intel Turbo Boost Technology present on latest Intel Core processors running Mac OS X.
