ASUS X99/Deluxe: Advice welcomed on base frequency - turbo frequency switching

Hi all,

First time post and with a question; I hope you regular visitors forgive that, but I assembled a new rig last week…

Advice would be welcomed here, on how to control the base frequency and/or how switching could be better optimized between base and turbo!

Here’s the issue.
I overclocked my I7-5820K on my ASUS X99/Deluxe to 4.5GHz (1.312V – I’ve got water cooling) and it runs stable on AIDA64 Extreme, which is all that I was asking for (BTW, got the latest BIOS 1702 installed).

At low load, the CPU is automatically tuned down to 1.2 GHz with a core voltage of 0.72. That is pretty lame; simple tasks (Internet Explorer e.g.) show slow response occasionally.

My system seems reluctant to step up to its new maximum settings: with the 3DMark it does go all the way turbo (which is logical) but PCMark8 gives unsatisfactory results for a rig of these specs; it doesn’t switch to high gear a good deal of the benchmark time.

I failed to find the appropriate BIOS setting for switching faster between base frequency and turbo frequency. I overlooked it maybe, or maybe that does not exist. But if it does not, then I would like to pull up my “base frequency” to about 2GHz for a more comfortable feeling on low demand tasks; yet I could not find any BIOS settings for that either!

Believe me: I have searched through your forum first, before posting this message. I could have overlooked an earlier discussion so pls don’t take offense if I am reiterating an unknown earlier subject.

The question is therefore: How can I tune this better?

Thank you for reading!

Hello

Set the Windows power plan to high performance and the CPU speed will not decrease. However there is no reason not to use the Speed Step features with this platform. If such simple tasks as Internet Explorer are slow something else is amiss.

Thanks.
I might just want to increase the minimum frequency somewhat - say to around 1.6-2.0GHz, but I failed to find where exactly to adjust this in the BIOS.
Could someone pls point me to the right parameter?

You will need to do this in the Windows Power Plan advanced settings > Minimum processor state.

Indeed, that did the trick!
Many thanks for your kind reply, that was helpful. 🙂
