For anyone who has a 4790k running hot, here is the fix that worked for me

[digmeahole1]

I am not a novice and this is not my second post. Miserable site made me change my user name when i registered a new mobo.
I just put together a new rig with a maximus VII formula and was pulling my teeth out trying to figure out why my new devil's canyon was hitting 80c at stock clocks and a fixed vcore.

I had to manually input the turbo watts as asus bios auto setting is WAY out of line for this cpu. photo is below and cured my issues. fully stressed for 1 hour on an older corsair h80 vcore at 1.150 volts 4.6 ghz high tems of 64-69c now. Also vcore was jumping up even though i had llc disabled. I had to set the FIVR to balanced to get rid of that. The values are CORRECT asus for some reason multiplies whatever you put in the field by 8X! :mad:

Credit to koroziv for posting this on the intel forum! TY:D

hope this helps anyone who needs it. & Asus...you need to fix your bios for this cpu. Posted all over the net....

heya folk,

i fixed that overheating for my 4790k!

Installed 1600mhz Ram that running with 1.35v instead of 2400 with 1.65v. Since that i can run Prime95(28.5) without hitting 80C(before 100C with throttle). The power consumption dont pass 6watt now, before i it was over 30w under load.

And i dont think there is any reason to fear power drain, because its doesnt matter if you use memory with 7.5 nanoseconds or with 10ns latency.
Typically industrial liars.

I'm surprised that lower voltage ram gives such a big difference in cpu temp.

I was struggling to keep my 4970k below 80C under full 8-thread 100% load with an H100i. It was very stable, but the heat concerned me. I had the fans and pump speed pegged at those temps and it was annoying to hear it moan with any blip in load taking it to 65-68C

I will need to go look at the settings this thread suggests, but in my case, it was simply a matter of setting the core and cache voltage to something other than auto.

I set them both to 1.3 and then walked down to 1.290 to find the minimum to remain stable.

4.8GHz Core @1.290v
4.6GHz Cache @1.290v

Peak temps are now 72-73C under 8 thread 100% load and ~65C for 4 thread 100% load. Real compute jobs doing actual work are typically more like 45-50C - it runs quite cool now - on par with my 5930.

It seems auto is downright dangerous when you get up there in clock speeds. I am running linux on this machine, so I don't know how high it got.

Very interesting find guys. Wondering if this would work for my 4770k??

The settings? idk^^

To replace your current RAM or reducing your timings/voltage should work 😉

hello digmeahole1 and all other users, :rolleyes:
you have an vii formula mobo , i have vii hero (you can see in my specs).
is this valid to set it on my mobo? i has never looked at this. my i7-4790K runs in default-mode with 4 ghz and turbo 4,4 Ghz. i changed from air-cooling to
water-cooling (liqmax II 240). my Temps on cpu (main temp) are not so high i thing , at 69-70 degrees @ full.
i can test it again, i not mind about the settings. maybe i should control the mobo-settings, but its not funny when you can't confide asus ,that they
have made correct default settings

to me its helped nice

Hello, after one year I stumbled also on this thread. I was curious about these settings and I've tried them and the results are a bit mixed for me.
While indeed now the temps at 4.4 GHz do not go over 35-37 C, the pc now feels sluggish, and much slower . For example with all settings as till now on AUTO
at login the rotating dots took one rotation and it was in desktop, now it takes at least 5 complete rotations to reach desktop. Any ideas?
Best Regards
M.

You need to verify that your bios have this flaw. My first thought is that you've entered these values in a bios which doesn't have the multipliers and your cpu is constantly throttling. Which is exactly what will happen if you set the TDP numbers to low.

I have finally found this and my pc can finally boot into windows.
Finally after about 6 months thnx
