i7 9700k thermal throttling at 4.5 mhz

[Abraxas8900]

Hello Everyone, since I built my intel computer the cpu had been overthrottling on anything over 4.5 mhz. I have a noctua nh-d15 chromax black cpu cooler I've change the thermal paste and resinstalled the cooler and i get the same results. the pc case that I'm using is a fractal design focus G with 2 corsair  140mm AF fans in the front and 1 corsair 120mm AF fan in the rear. The cpu over heats on any frequency over 4.5mhz. I don't know what could be the problem, maybe I didn't win the siliconlottery or maybe the cpu cooler is faulty or maybe I just need to change the fans to SP? Here are my pc specs asus tuf gaming plus z390 motherboard, Cooler Master MWE 750 Gold Full Modular, 80+ Gold psu, Samsung 970 EVO SSD 1TB - M.2 NVMe, Toshiba X300 5TB Performance Desktop and Gaming Hard Drive 7200 RPM 128MB Cache, 2 8gbs corsair vengance 3200 ram, nvidia dual 2080 oc gpu and i7 9700k cpu. can anyone here please help me to fix this problem.

Ghz I hope. What are your case temps?

What does this mean? What temperatures are you getting idle and under load with your CPU at 4.5Ghz?

[Abraxas8900]

on my ai suite shows ratio: 45   4500mhz with cpu cache ratio: 46x  the cpu vccio voltage is at 1.30v

[Abraxas8900]

in idle I get 36.c and at all cores i get 100C

[Abraxas8900]

I don't know how to measure temps in the case,

At what workload? 

Ambient temps ? What cpu voltage?

I would suggest dropping that down. 

And why is your chache ratio faster than your core ratio? 

[Abraxas8900]

my first time overclocking so I was just matching the cpu cache with the cpu frequency . what voltage do you recommend on the cpu and for the cache ratio?

Intel runs hot, dial back the overclock if you don't want to damage your CPU

[Abraxas8900]

I benchmark the cpu using the intel extreme tuning utility.

Vccio at 1.3v? 

Are you extreme overclocking this thing?

 

Lower this to like 1.1v

Cache overclocking brings nice additional performance. Mines usually 4.7-5.1ghz depending on what benchmarking I'm into that day. More = better there for sure.

u shouldn't do that, i dont have the chart anymore but iirc it's 1.15v for 4.5ghz for ALL 9700k, and the cpu cache should be 200mhz below the cpu frequency, all 9700k should be capable of 4.7ghz at 1.3v vcore, my guess is the vcore ur cpu is actually getting is too high hence the 100C. check it with hwinfo and post it here.

 

u dont need 1.3v on vccio unless ur ram is at 4000, 1.25v is enough

 

if u end up sorting out the issues, i recommend a 5ghz oc with a 4.8cache, there seems to be a big jump for me from 4.7 to 4.8 in performance.

[Abraxas8900]

i lowered the voltage to 1.1 what you recommend on the cpu cache ratio

Yea. But not necessarily Better than frequency overclocking. Which is still better than cache overclocking. In terms of performance benifits.

No the cache "shouldnt" be below the cpu frequency. That doesn't hurt anything except adding a little heat. 

 

Vccio at max 1.2v. 1.1v should be plenty.

it's proven that cache at the same ratio as cpu can cause instability, only 5% of cpus can do cache=cpu freq

 

depending on his ram 1.1v might not be enough, this isnt zen, max for io is 1.3v for everyday use

Oh? 

I really need to re consider my overclocking I guess lol.

 

Nah brah. Cache overclocking is real good. Most chips up to 5ghz. Some 4.9. Some 5.2.

That's silicon lottery. 

 

You'd be surprised the performance from that cache overclock.

I dont have these issues like you describe them

 

Mines 8700K. Try looking at the sig a little more closely.

[Abraxas8900]

so what should i use on 4.5 with the cpu cache

i would love to see a chip getting 5.2 cache, doesn't happen, steve got a chip that couldnt even hit 4.8

use cinebench r15/r20 or blender instead for everyday loads, if ur just gaming ull never hit those temps.

Who's Steve? 

 

I've benched mine at 5.1 and 5.2ghz is a little rocky, but I'm sure to pull off a screen shot.

so what should i use on 4.5 with the cpu cache 

Vccio and Vccia both no higher than 1.2v

 

Be sure your board if these on auto aren't pushing 1.4v like mine does. Way to much. Not needed.

[Abraxas8900]

so what do i use for a cpu frequency of 4.5 on the cpu cache ratio?
