Overclocking Omen 880-p1xx - i7-8700K? (

[callahan09]

In the Omen Command Center, I am in the overclocking menu.

Here's what I tried so far:

Processor Core Ratio: 45x

Processor Cache Ratio: 45x

Core Voltage: Default

This jumped me from 2207 at defaults up to 2317 on the benchmark rating.

I changed core voltage to 1.200 and the result actually went down to 2297.

What is the max voltage of this CPU?  What is the default voltage?  I guess if I keep raising it until ti settles my benchmark at 2317 that's probably the default voltage, by why doesn't it just tell me what the default is?

Also, I don't really understand what these settings are actually DOING.  What is "Processor Core Ratio"?  Why can't I just pick an actual number in GHz to set the clock to?  What do these settings do, and how do I use them to set a stable but fast overclock on this CPU?

Any help getting this thing dialed in would be great!

Hi, I have the 8700k in my Omen as well and my video covers overclocking here. https://www.youtube.com/watch?v=AnQ4garCyvw

In short the voltage slider does absolutely NOTHING. You are limited by the preset voltage HP allows and the max you will see on all cores is 4.6

Hi FGW

Watching your video.

Very nice explanation on HP's overclocking options using the Omen Command Center.

x8 on the primary x16 slot is an HP, Dell, and possibly other OEM system builder's design choice.

A Z370 Asus Maximus X Hero MB runs one graphics card in the primary x16 slot at x16.

I have checked quite a few Z170, Z270, and H170 MBs manufactured by Asus and Gigabyte using CPU-Z and GPU-Z.

All of these MBs run the primary x16 slot at x16. Two cards in SLI or Crossfire run at x8/x8. Three graphics cards (if supported on the MB) run at x8/x4/x4.

The change in system performance between x16 and x8 is statistically insignificant.

But I am at a loss as to why any MB OEM or system builder OEM would degrade the primary x16 slot when Intel provides the architecture to run one graphics card at x16 in the primary x16 slot.

I have asked HP about this myself a while back.  Still waiting to hear back about it. 

Although I wasnt aware that Dell did this too. Good heads up.
