Posted February 1, 2017 So I decided to OC my 4690k, currently on 1.3v and 4.7 GHz. On cpu-z it shows that the multiplier is (8-47) but the clock speed is only at 3.5 GHz (stock) Did I miss some settings in my bios or what?

Posted February 1, 2017 Author Quick update, I see this speed when running prime95 with large FFTs (max power consumption) but when I'm browsing the web or through files on my pc I see the speed spike p to the correct 4.7GHz.

Posted February 1, 2017 does it boost to 4.7ghz at all? under a heavier CPU load? ex. when playing games or anything else demanding? Photography / Finance / Gaming Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

As I just posted, when going around through my files or going on chrome it DOES go up to 4.7GHz, I'll do a quick fire strike physics run now to see if it will boost to 4.7 Link to comment Share on other sites More sharing options...

Posted February 1, 2017 Author Alright so during the physics test the multiplier was sitting around 4.2-4.3, sometimes spiking to 4.4-4.5. I'm assuming that there's something with lack of power delivery, since I have a fine cooling solution (240mm rad) Link to comment Share on other sites More sharing options...

I alos jumped into the bios and saw that I had 2 options, base clock and multiplier clock (at least I think that's what they were called). As it turned out the multiplier was 4.7 but the base was somewhere in the 90's, causing my effective speed to be around 4.5. I changed the base to 100 so my speed should be 4.7, but I still see it dipping in fire strike. Link to comment Share on other sites More sharing options...
