I don't think you need something accurate. We don't know whether it is implemented through ACPI or similar to the old = turbo jumper on the MB, which increased the clock rate and sometimes the vo= ltage ( required to maintain stability when increasing the clock rate). We = don't know how your MB manufacturer implemented this. My guess is it's probably through ACPI but you don't know until you have so= me rough measurements. --- Sent using a tiny phone keyboard.

Do you mind=20 > running some benchmarks with and without turbo mode? What could be adequate benchmarks for this? Something likje "openssl speed aes128-cbc" or I need more specific one? --=20 // Lev Serebryakov
