Core i7-4770k running Prime95 hot. Is it safe?

It probably isn't good advice to tell someone who isn't even sure if he mounted his cooler properly to delid their CPU.

Give us a CPU-Z screenshot. The input voltage is fine at 1.7v, but your core voltage might be running too high. At stock speeds you should never hit 100°c no matter what you run.

+1 on the input voltage, 1.7-1.9v iirc is the safe limit. Check the Haswell Overclocking Thread @OP if you wanna know more!

On Haswell/Devil's chips and cooling...I've had several 4770k and 4790k chips that hit their 100C thermal limit on stock cooling with no OC or adjustments to link core turbo boost, and all it took was BF4 or a CPU stress test (really any of them with stock cooling...). I totally agree with aftermarket cooling at stock speeds it shouldn't necessarily be hitting 100C. Now with that said, I've also had a handful of both of those CPU's not hit their thermal throttle limit with stock cooling and testing...but that also depends on ambient temps, airflow and the stress test being performed.

@OP Also look into trying OCCT, that's my utility of choice for testing the CPU, RAM, MB, PSU and GPU. :toast:

Also when you just use your PC and game, how are your temps? Use HWMonitor for Current Min/Max recordings. :toast:

don’t miss out the complete topic about coolers, OP is running a Cooler Master Seidon 120V, pretty decent for having that processor safe, chilled and on some good temps, and also as far as he said, paste is properly applied, is a decent paste [provided with AIO unit,] so the point here is that something may be miss plugged, or also not working,

we will make a list:

Cooler is pretty capable,
Also thermalpaste is …. and the full unit is supposed to be well installed…
fans, well OP said that are spining, we don’t know so far that mucho about it …

this is all information we know,

So, Fill your specs here! for futher info… we will continue troubleshooting this…

also let us know something more about your cooler, your fans and the current Setup on them,

Regards,

1.95 is save, but over that it can start popping chips.

Kursah · Dec 16, 2015

I've always aimed for 1.65v when working with my chips...not allowing over 1.75v even when OC-ing. Generally I've been undervolting my 4790's with a little success.

For some reason I thought the seidon was air.

My chip will hit 90-95c at 4.4, with only AIDA FPU test which is similar to prime small FFTs, and thats with 240 and 360 rads in a custom loop.

Granted it doesn't hit those temps at stock though.

I already pointed this out, it isn't the input voltage that is the issue, it is the actual vcore. It shouldn't be going up to anywhere near 1.3v under load. My 4690K does 4.4GHz@~0.98v, and my 4790K does 4.6GHz@~1.10v.

That being said, a large part of it is also likely just Prime95 w/ Small FFTs, because even with a H100i, it can cause my 4690K to hit 100°C.

Totally agree man. My chip does like 1.06v at stock under load. So yeah something is wrong with his setup. Because he also shouldnt have to change anything in the BIOS if its been cleared and set to Optimized Defaults afterwards. OP either went in an tinkered with it, or BIOS is setting it wrong for stock.

That's a nice chip. My 4790K needs 1.28v for 4.5, and needs tons more voltage for 4.6 and up. I mean, definitely not all chips clock 4.6 @ 1.1v

Frenzic · Dec 16, 2015

Don't use Prime95, it's a killer. Just use your PC for everyday stuff, that is the most important test. Gaming, browsing, encoding, what ever you do day to day, like Furmark with GPU's Prime will ruin your CPU. Prime will send most CPU's north of 90°C. You could maybe try a general stress tester like RealBench.

Yeah I know, but the point is it shouldn't be 1.3v at stock speeds.

I hate benching , I set some clocks up and some clocks down and always test my settings with some work, gaming or designing some craps.. I avoid to use them, CPU-Z has a benchmark, that will work for testing stability,

Yeah just everyday use is the best and most important test. I don't think anything you do will stress the poor CPU like Prime.

I only said RealBench not for the benchmark but for the stress test that's included with the program. It should give your CPU a good workout like every day use would do and not cook it. If it is running close to throttling temps after that then it may need some attention

CPU's are made for being used... not for being fried....

For all of 5 seconds. 32m test in wprime, all 4 boxes checked in Aida stability test for 30 minutes to an hour, Realbench 5 loops, entire 3DMark Suite, 1+hours of battlefront and couple rounds of 1000+ ticket servers in battlefield 4 is what I do for testing stability. All different and realistic loads on the CPUs. With,varying memory load as well.

Frenzic · Dec 16, 2015

Battlefield 4 will find weaknesses that stress tests etc. won't, that's for sure

No.not with temps like that.
Try Cinebench and Hyper-Pi 32m
If your chip isn't roasted.

burebista · Dec 17, 2015

Guys I agree that for 99% or users running stress tools is useless but in any circumstances his CPU shouldn't throttle with default settings and an aftermarket cooler no matter what test is running.

Something is wrong there. Dunno what yet. Seating cooler, thermal paste, malfunctioning pump/fan, bad contact between IHS and CPU chip.

Hyper Pi? You mean Super Pi. Or wPrime.

Oh a modified superPi. Meh.

I guess you're right, I will try to reseat, and apply thermal paste again. Btw, I used X thermal-paste method on CPU, does it work well? I can't see anything under the heatsink. Other steps are logic but only this step, these were my first tries to apply thermal paste.
