If it boots, try to stress. If it blue screens set it to 1.1v, if that fails try 1.15v and if that fails try 1.2v. You shouldn't have to get much higher than that for 44x.

Edit: ~216 W under load is crazy, play with your vcore and that should come down a lot. As a comparison, I'm hitting ~120W under stress.

While i'm doing that shall i increase the multipliers for 4.6?

I would make sure you can get the temps down with stock settings first, then go up from there. There are more bios settings you should change besides the Vcore if you are going to do a real OC.

P95 took my old 4790k up to 100 in about 3-5 seconds... OCCT never passed 60

Okay after some trial and error.

I got it running at 1.75 VCORE running prime95 at 58-65 degrees on a blend in test. Before this it would either crash after boot during stress or the cores would be locked at 4.0. Now it's working 4.4 at 1.75V at 110W max according to HWmonitor.

This bios is very elaborate.

If i want to overclock it to lets say 4.6 GHZ.

Do i increase the multiplier which is x40 or do increase the multiplier from the turbo boosts which is x44

Besides that what other settings do i change?

I'm following this tutorial now https://www.youtube.com/watch?v=ujCmFYd898U

I dont know all the voltage settings he talks about in the middle of the video.

Theres one he puts to 1.9 ?

Check out this link. It has specific settings for each motherboard make. I wouldn't worry about the power saving settings.

Workshop: How to overclock Haswell processors

I set my VCIN to 2.0v and my ring to 1.050V with a uncore mult of 40x. I then found my most stable core mult and votlage. After you are happy with your core OC you can work on lowering your input voltage and increasing your uncore mult. I was able to get my input down to 1.65v and my uncore up to 42x with Vring at 1.050, you can get a higher uncore if you increase vring, but you wont get much gain performance wise. Good luck and feel free to ask any questions here or in the DC owners club in my sig.

Every 4790k I had on stock cooling hit 100c playing BF4 multiplayer. I've had at least half a dozen. It boosts to 4.4 (depending on the board) using one of the wimpiest coolers around.

Thanks ill give it a read tomorrow.

I think it confusing what voltage to put my CPU RING at.

Also i find it confusing that the CPU VRIN ext override voltage is being set so differently by people.

Why do you want to overclock your uncore? Isn't uncore all the NON core parts of the CPU like the Cache , and Bus?

I just want to overclock my max turbo speeds to 4.6 ( 200 mhz increase )

I was thinking of putting it at 1.2 vcore 1.8 CPU VRIN (intel advises 0.4v higher than vcore.

And yeah.. the CPU ring... i have no idea what to do with that.. ill probably lock it at 1.15?

All these things set, can i now OC my turbo multiplier?

What is uncore overclocking and how does it help me.

Thanks for the answers and the read.

I'm off to bed for now.

Good night

RING is your uncore's voltage. I set mine at 1.050v, some people set it higher to try to get a higher uncore ratio.

Uncore controlls your cache, ram, and pci communications. I would recommend taking it off auto for overclocking and setting it at ~40. You get very little benefit going any higher, and I started getting errors and glitches while gameing with it set over 46.

I think 1.2vcore and 1.8vrin is a good starting point. You may be able to go lower or have to go higher.

just as I suspected, too high of a vcore. 99% of people who have problem with intel chips, comes down to lack of vcore knowledge. I guess you could blame the motherboard manufacturer for being overzealous out of the box with vcore settings.
