Real-World 5820K Turbo Speeds

Go to solution Solved by xConVirus,

I went into the BIOS and the Turbo Boost option was set to "Auto", I switched it to "Enabled" and now it honestly seems like all cores are running at 3.599GHz which is what I thought it should have been. Thank you for all the advice and information.

Posted

So I'm running F@H on my computer here at full, and I just noticed that with my CPU usage between 97-100% usage, and temps barely touching 60 degrees Celsius, it's looking like the maximum GHz I'm hitting is 3.339GHz. This seems odd to me because according to Intel Ark, the 5820K Turbos up to 3.6GHz, so I'm wondering why it's lower. I haven't overclocked it at all, I'm just wondering whether there may be some setting I don't have enabled or something? Not a pressing matter, I'm just curious and procrastinating. Thoughts are appreciated, thanks.

The turbo boost could be disabled in your bios by default, which seems unlikely and dumb but just a hypothesis

CPUID HWMonitor.

I will check that out.

I don't really want to overclock it myself just yet. I just thought the difference between the GHz I'm getting and the GHz advertised was curious.

turbo boost only reaches full frequency when only one core is at 100%

the more cores that are at 100%, the lower the frequency will be

this is to conserve the rated TDP

 

to have all cores turbo boost you need to OC and "sync all cores"

Your i7-5820K should only boost to 3.4GHz under 3-6 core loads. 1-2 core loads it boosts to 3.6GHz. You can see the boost table HERE.

 

If your bclk is not 100MHz flat, it will report your CPU speed as being higher or lower than your multiplier would make it out to be. For example, with a 39x multiplier on my CPU at 99.76MHz bclk speed, windows task manager reports me as using 3.84GHz, and throttlestop/HWiNFO/etc report me as being somewhere around 3890MHz.

I have finally moved to a desktop. Also my guides are outdated as hell.
