gbohn Posted January 24, 2017 Share Posted January 24, 2017 Hi; I'm trying to determine what core speeds I'm getting from my cpu (E5 1650 v4) under Windows 7 64-bit. I'm very confused by the different values I see in different locations (I'm thinking I just don't fully understand what gets reported when/where). My understanding is that this CPU has a base frequency of 3600 MHz, with a Maximum frequency of 4000 MHz (according to the Intel ARK page). Are the AIDA64 Motherboard/CPU and Computer/Summary pages 'static' in the sense of just reporting the CPU type, or dynamic in the sense of showing what the CPU is currently up to? The Motherboard/CPU and 'Computer/summary' reports the CPU as a 'Hexacore Intel Xeon, 3800 MHz (38 x 100)'. If this is just a 'static' informational display, should that really be 4000 Mhz? Or is this what is currently being used? Running under light load, I can see that CPU-Z reports a core frequency of 3796 MHz or so (for at least some part of the CPU). If I start Prime 95, then CPU-Z reports a speed drop to 3500 MHz or so (But I thought the minimum frequency was 3600 Mhz?...). But in AIDA 64 the two above pages report the same values as was shown under light load. Does AIDA64 have the ability to show what frequencies are currently being used? I have the 'Intel Turbo Boost Max technology 3.0' utility installed, in case that makes a difference. Thanks; Quote Link to comment Share on other sites More sharing options...
