Posted July 15, 2017 Hi, I have a Intel(R) Core(TM) I7-4790K CPU @ 4.00GHz But, its not at 4.00, its like 4.28 and higher, then lower then higher, and its never just 4.00ghz So I was wondering if it mattered if the cpu was locked at a current voltage or if it was unlocked. Would it have performance issues or would it be the same? Zambosoe, was here.

Would it have performance issues or would it be the same? The minimun guaranteed speed for the 4790K is 4.00Ghz. The maximum is 4.40Ghz (2 Cores, Turbo Boost). Depending on the situation and the thermals, the CPU will "autoOC" itself, at least on the best core (not all at the same time) to a number between 4-4.0 Ghz. It is safe, and it is as expected to work. Just leave it be.

Posted July 15, 2017 It matters in the sense that if it's higher on the same CPU, you will have more performance, but small GHz differences are normal. Your CPU goes faster when it needs to and can go slower if possible (to conserve energy and thus put out less heat) "We're all in this together, might as well be friends" Tom, Toonami. mini eLiXiVy: my open source 65% mechanical PCB, a build log, PCB anatomy and discussing open source licenses: https://linustechtips.com/topic/1366493-elixivy-a-65-mechanical-keyboard-build-log-pcb-anatomy-and-how-i-open-sourced-this-project/ mini_cardboard: a 4% keyboard build log and how keyboards work: https://linustechtips.com/topic/1328547-mini_cardboard-a-4-keyboard-build-log-and-how-keyboards-work/ Link to comment https://linustechtips.com/topic/807677-dose-cpu-speed-matter/#findComment-10144847 Share on other sites More sharing options...

Posted July 15, 2017 CPU speed changes depending on on the load it is under. Plus task manager isn't too accurate as it thinks my 4.6ghz i7--4790k is at 5.2ghz PC Specs: CPU: Intel i9 12900K CPU Cooler: Corsair Hydro H150i Elite Capellix Mother Board: MSI z690 carbon WiFi RAM: Corsair DDR5 6400MT/S Storage: 2TB Samsung 970 Plus NVMe, 240 SanDisk SSD Plus, Crucial MX300 750GB SSD GPU: Nvidia RTX 3090Ti FE Case: Phanteks NV5 PSU: Corsair RM1000X OS: Windows 11 Home Monitor: Acer Predator XB271HU 27" 1440p @ 165hz Keyboard: Razer Black Widow Chroma Mouse: Logitech G502 Sound: Sony MDR 1000x Headphones, Blue Snowball Microphone Laptop Specs: Gigabyte Aorus 15G CPU: Intel i7 10875H RAM: 16gb DDR4 Storage: 512gb NVMe, 1TB Crucial MX300 SATA SSD GPU: Nvidia RTX 2070 Max-Q Link to comment https://linustechtips.com/topic/807677-dose-cpu-speed-matter/#findComment-10144853 Share on other sites More sharing options...
