Intel 9900k.. my findings.. Heat..

[trog100]

this is only applies to my recently acquired example..

in some ways it seems a good example and maybe in some ways its a bad example... good.. it runs at 4.8 on all cores on what i consider a very low core voltage with minus offset of 0.08 it runs between 1.68 and 1.20.. but even at these low voltages it runs silly hot.. 10 minutes of handbrake has it at 100 C and its beginning to throttle..

i have just taken the cooler off and reseated it just to make sure there wasnt a problem there.. there wasnt..

it is a very hot summers day here in the UK room ambient is 27 C.. the system is now idling at 31 C.. a not a lot over room ambient..

gaming wise heat isnt a problem.. gaming temps are around 65 C.. quite clearly games dont load a 9900K much.. the much lower temps reflect this..

heat isnt a problem ether if the chip is set to stay within its intel claimed 95 watt tdp.. sadly the chip throttles down to just over 4 g when in this mode.. not exactly what i bought the f-cking thing for.. he he

wow 100c I don't think ive ever hit that with any cpu in the last 5 years, you might want to try some water cooling.

Are you talking about voltages there? 1.68V would be anything but low.
Did you overclock manually or let some motherboard or software do it automatically?

Edit:
If you did not actually overclock, it is running on some stupid MCE settings with automatic overclock.

1.68V holymoly xD mine is 1.37V @ 5 ghz all cores.

1.68V holymoly xD mine is 1.37V @ 5 ghz all cores.

a typo on my part.. the lower reading should be 1.168 not 1.68.. whoops

at a more normal 1.35 volts 5 g my chip would catch fire.. he he

what i have been trying to do (and having difficulty) is run a modest 4.8 g without it hitting 100 C and throttling when all cores are under full load..

trog

ps.. my 8700K ran hot at 5 g.. 4.9 was its sweet spot... in some ways i am not supersized at the results i am getting.. adding 33% more cores in the same sized package aint gonna come easy and in my case it dosnt..

i am not on some silly auto overclock.. i am very carefully undervoited to the point of instability setting in or very close.. i am running 0.080 offset of what would be something around 1.3 volts auto..

 

[Hockster]

That voltage is way too high. My 9900K does 5.0 on all cores and only hits mid 80"s running Handbrake.

Edit: Saw correction, what cooler are you using?

 

[Vario]

I'd consider returning it for another one, the heat seems unreasonable. If it hits 100C in workloads, then the heatspreader is defective, probably bad solder job. Remount the heatsink again to be sure of course.

If his system specs are accurate - Dark Rock TF .

 

[FreedomEclipse]

I personally see that CPU cooler as inadequate for an overclocked 9900k. Its no DRP4

1. Idle temps do not matter, really. CPU sensors are more accurate the higher they go (closer to max).

2. Gaming temps are typically MUCH lower than any stress test or handbrake. That is quite normal to see 20-30C+ differences. Thus is common for any chip.

3. That cooler isnt great in the first place. In fact it's nearly 15C off from top notch air... that's a ton. If you want 5ghz on that cpu, get high end air or a 2x120mm AIO.

be quiet! Dark Rock TF Review

Can a mid-height downdraft cooler keep up with our overclocked Haswell-E CPU? We put the Dark Rock TF by be quiet! through our tests to find out.

4. Where are you getting your vcore reading from? Cpuz? HWmonitor64? Coretemp? You may want to confirm your running voltage at the same time. Perhaps post a screenshot of where you are seeing this. Yes, I saw the (still uncorrected) typo in the first post..

Be sure to artificially limit it after you resolve the heat issue. "He he"

This. That cooler loses to a 92mm tower cooler...

With the 9900K, you either have to go extreme high end air cooling or at least 240mm AIO if you want near 5GHz under full load. Also, if you use an air cooler, you better have some damn good case airflow, otherwise that thing is going to heatsoak pretty quickly.

i get near the same results at 4.7 which dont consider an overclock.. my cooler is okay or should be for what i am doing with it..

let me be clear here.. i have been doing this for years and do have a vague idea of what i am doing..

i am also surprised at the results i am getting.. firstly how low i can get the core volts and secondly how f-cking hot this chips runs even at a very low core voltage..

one other thing to note.. the higher the core thread count the greater the temp difference between software that used them and software that dosnt.. in my case with this chip a good 30 C difference between division 2 65 C and realbench 100 C and throttling..

i aint doing nothing wrong here and have spent quite few hours in and out of the bios trying different options.. where i am now is about the best i can get..

keep in mind i am not trying extreme overclcocks.. just something i consider usable and lucky for me i dont do much video editing..

to repeat i dont want 5 g.. would be happy with 4.8 or even stock at reasonable temps.. currently my case has both sides off i am still fiddling with it.. my ambient case temps are the same or very close to my ambient room temps..

please read whats already been said folks before chirping in with irrelevant comment..

my TF cooler blows air down on the motherboards hot bits its also augmented by a pair of case side fans which blow directly at it.. .. it works well and is as it is for a reason.. it work better then a normal side blowing tower cooler.. i have tried them..

Theres like 3 people AND a link which tells you otherwise. Denial is not just a river in Africa.

let me be clear here.. i have been doing this for years and do have a vague idea of what i am doing..

Operative word in bold.

am also surprised at the results i am getting.. firstly how low i can get the core volts and secondly how f-cking hot this chips runs even at a very low core voltage..

please confirm your voltages. What software? Did you run handbrake at stock and see the load voltage?? Temps i'm concerned about your process and what voltage you are actually running...post screenshots... confirm with other software listed...

Your refusal to even consider other people's opinion is incredibly off putting. If you dont want to listen, dont post in a forum and start a blog instead.

 

[TheMadDutchDude]

Yep, that cooler is sadly the issue. It's good, but not good enough for the 9900K with an OC.

 

[newtekie1]

For someone making passive aggressive remarks about other's reading what has been said, you sure didn't do it yourself. I said NEAR 5GHz. Please read whats already been said. 4.8GHz is near 5GHz.

currently my case has both sides off i am still fiddling with it.. my ambient case temps are the same or very close to my ambient room temps..

The fact is, this is an 8-core chip. It doesn't matter if you think the cooler is adequate. It isn't.

well...

If you have years of experience. Know or can guess whats going on why are you asking for people's help and/or opinions when you are pretty much hell bent sticking to your own deductions and ignoring others?

Anyway - youve had multiple mentions about the cooler - threw that opinion out the window in the rudest fashion.

I hope you manage to get to the bottom of all your woes. Im out of your threads.

 

[Vario]

You should check the other voltages as well. Some boards like to overvolt these and that would also be additional heat not to mention diminished lifespan. Intel specification is 1.05 for VCSSA (system agent), 1.0V VCCST (cpu sustain supply voltage) and .95 for VCCIO (memory and cache controller)

 

[trog100]

let me make another thing very clear.. i am not asking for help.. simply reporting my findings regarding my recently acquired 9900k chip and how its behaving for those that maybe thinking of buying one are who are simply interested.. google does produce some very conflicting results i have pretty much read them all before posting my own results..

this pic shows very nice voltages but f-cking terrible temps.. under volting laptops is common practice to avoid excessive throttling.. with intels latest 9900k it seems careful under volting is required even on a desktop.. the pic is after five minutes at full all core load.. it wont run much hotter but its at its throttling point..

[TheMadDutchDude]

Your CPU at 4.8 GHz and 1.2v has >220w of TDP, fella. No wonder you're struggling...

Your cooler is not adequate, as mentioned.

 

[EarthDog]

.....and do other pieces of software agree? Why not run hwmonitor and capture mins and max and confirm.

Also, handbrake uses AVX iirc, so voltage when running it will likely be higher. Why you showed it with a different app is beyond me........

I'd also check the other voltages like was said above. If you enable xmp, chances are it raises those which could save a few degrees...

But in the end, your cooler just isnt up to the task as we said initially. A 9900k runs hotter than your previous chip. If you want to be "near" 5ghz, you'll need a better cooler.

Your CPU at 4.8 GHz and 1.2v has >220w of TDP

Do tell how you came up with this.

 

[TheMadDutchDude]

I just used one of those PSU calculators with only the CPU info configured.

There is a formula for it, but my link/knowledge is just lacking on it right now. I tried an old-school one, but it came out at 133w, which is massively wrong.

 

[dorsetknob]

Do tell how you came up with this.

Scientific Accurate Guesstimate.??
Its a Known (not Rumoured) Hot Running CPU
go 240>280 AIO or full Loop Otherwize this heat will drive you loopy

Not with proper cooling. Mine didnt...

....and neither does my 9960x with all c/t running 4.4 ghz. It's all about the cooling. You are also overclocking with all c/t that high. Have you tried at stock? I bet it still gets toasty... but better.

Get a more appropriate cooler for the job (4.8ghz).

 

[londiste]

What do monitoring tools actually report as power draw?
Handbrake is probably AVX2 load. Very-very heavy if you run without offset.

first of all your chip is not my chip.. as i said right at the beginning my findings can only be applied to my chip.. as for your comments about getting a proper cooler.. rubbish for what i am trying to do...which is run close to stock at very low core voltage setting my cooling set up should be ample..

i have tried running this chip with hyperthreading off.. gaming temps are about the same which does kind of show games dont use much more than 6 threads..

all core full load temps come down massively i can run 5 G with HT off quite easily with temps less than 80 C..

oddly when i saw the core voltages i could get away with i thought a very good chip.. when i saw the temps on an all core load i thought differently..

having said all this.. this does all fit a logical thought pattern.. the 8700K 6 core 12 thead chip runs hot.. it figures adding 33% more cores is gonna make the 9900k f-cking hotter still... nothing comes free..

soldered on heat spreaders or not.. the intel claimed 95 watt tdp is also an out and out lie... what puzzles me is how they get away with it..

at a 95 watt tdp the chip throttles right down to about 4.2 gig.. and remarkably enough the temps dont go much above 60 C ish with full all core load..

i can post a 95 watt limit example and an HT off example if anybody wants to see them..
