Hi guys.

First: Im not really wisely on this topic so i apologize if this is stupid 🙁

Second: Recently bought a pc (i5-4690, asus z97m plus, x2 kingston fury 1866mhz, power supply, etc) andi wanted to check if everything was okay, my ram was not running best speed cause bios settings and i fixed it! >But now the cpu... i dont understand anything heh.

Going to the topic I tryed to this bymiself , found out cpu-z was the good choice to know if everything was ok, but honestly i dont understand anything here on the cpu tab, i think bus speed and core speed should be higher? but i dont know really.

So that's what i want to know, if everything here is okay, and if its not, how to fix it! As i said i think bus speed and core speed should be higher? 3.50 GHZ Its what the 4690 runs (i think u already know xD)

Thanks for taking the time to read.

PD: Native spanish here so sorry for grammar mistakes. Let me know my mistakes so i can learn!

Everything looks fine. Family, model, stepping etc are technical details that don't mean much to most people, so you can ignore that for the most part. It's just telling you all the details of the processor.

Bus speed looks a tiny bit low but is roughly 100mhz which is where it should be. It's known as a 'base clock' speed. The cpu speed is a factor of the base clock or bus speed x a multiplier. At 3.5ghz (3500mhz) it's 100mhz bus speed x a multiplier of 35 (x35). In the photo it shows the cpu speed as 800mhz and says the current multiplier is x8 (8x100mhz = 800mhz). Multiplier in parenthesis says (8-39) meaning when the cpu isn't doing much work, it lowers the multiplier to 8 (800mhz) to save energy. Part of intel speed step which is...

Multiplier in parenthesis says (8-39) meaning when the cpu isn't doing much work, it lowers the multiplier to 8 (800mhz) to save energy. Part of intel speed step which is a built in feature. When the cpu has work to do, it will go to x35 (deafult stock speed of 3.5ghz) and if it needs more power to process it can go up to a multiplier of 39 (3.9ghz). That's part of intel's built in 'turbo boost' feature.

The way turbo boost works, if only 1 core is active it can boost from 3.5 to 3.9ghz. If 2 cores are loaded, it will go to 3.8, if 3-4 cores are fully loaded it will raise to 3.7ghz. That's why the cpu z multiplier says 8-39, with no load it can drop the speed to x8 at full speed (on 1 core) it can go as high as x39. That's the built in automatic multiplier range. Cpu speeds on newer intel's are dynamic, they're not 1 fixed speed anymore.

Everything looks normal. If you were to run a stress test or be playing a video game or something and looked at cpu z you would see the multiplier higher than x8 as more cpu power is needed.

Thanks a lot! I didt test it and its right, it goes higher. And if bus speed should be 100 then i really dont care about that little bit, cause usually it says 99.98.

Really apreciate it.
