i7 4470K not running at max capacity

post #1 of 8
Thread Starter 
Built my system today, at idle I switch between 800Mhz and 3.5Ghz (when I move my mouse or other minor things happening), but every tests and encoding I did show the cpu stopping at 3.7Ghz. How come it's not going upto 3.9Ghz? I'm staying stock for a couple of days, but how come I don't get the full potential of stock?

You are only guaranteed to have it hit 3.5Ghz. The 3.9Ghz boost. Here's what Intel says about TurboBoost 2.0:
Quote:
Availability and frequency upside of Intel Turbo Boost Technology 2.0 state depends upon a number of factors including, but not limited to the following:

Type of workload
Number of active cores
Estimated current consumption
Estimated power consumption
Processor temperature
[Source]

Basically, the OS and chip decide what clocks are actually safe/necessary for the task it has to do. The 3.9Ghz limit tells you that the OS and CPU will never decide to go above this clock speed for any given task on their own. So, your chip is perfectly fine, in some rare situations, it will happily hit 3.9Ghz probably for short periods of time to complete certain tasks

Oh my... ok. I'm a little bit disapointed hehehe, I'm encoding at about 10% faster than my old i7 920@3.7Ghz. So hertz for hertz, the 920 was a beast. I don't understand though, I read MANY webpages saying encoding times were almost TWICE as fast as the i7 920 (*but* I suppose at stock speeds). Frankly though, I was expecting at the very least a 20% increase.

Until I overclock, I'll be disapointed lol! biggrin.gif

Yeah, for most uses, there haven't been much performance gains for the past few years lol. Attempt to OC to 4.0Ghz+ (might need to change your cooler). K series are meant for overclocking anyway tongue.gif

Why people saying I should change my cooler? It's brand new, and is rated BETTER than the CM Hyper 212 Evo, and with my tight budget was told to get the latter. I'm currently at 24°C at idle, that's 12 degress less than my old i7 hehe. Why the change? biggrin.gif

If you overclock it, it is recommended to have something better than that is all. That noctua one is real popular for air cooling but my hydro series h110 is beast. Can't really beat it for how low maintenance it is. it's basically lazy man's water cooling

The hyper 212 is better

But there are better heatsinks for the money
