which app for overclock

[rolic]

I plan to overclock my 8700k

 

Is realbench good for cpu stress test, heard prime95 is too much

Use blender and render the bmw's? wouldnt it be too short of a test?

[Firewrath9]

i use aida64 for stabilty, cinebench for benchmark. aida64 overnight w/ fpu is a great burn-in, and stabilty, and creates a shit ton of heat, although i've heard 95 is better.

what is max temps stressing under aida64?

yes and prime95 is fine, download prime95 26.6 version. in 26.6 use these stress test settings: min and max fft size: 1344 / select run fft's in place.

occt is great as well

Linus has stated that their be all end all test for cpu stability is blender

rendering bmw image or what image, i dont know much about blender

[TahoeDust]

Prime95 w/ AVX off, OCCT, RealBench, Aida64....in that order.

[Cyracus]

I believe he name dropped bmw and classroom, and maybe barcelona.

but dont those rendering last only around 5 to 10 minutes?

See my post above.  Those are what you need to be running.

Blender can loop renders. But Prime 95 is the best for all out thermal and stability testing.

 

If your system is stable on an all-night Prime 95 run, it is stable.

im scared about the temps on prime95, i hit 94C in 15 minutes

Then lower your OC. Clearly it's too much for your cooling.

but in games i have never hit passed 72C, playing for 12 hours straight

 

i mean i am using version 29.4 if that matters

Yes. Because your CPU isn't under 100% load in games. But if your OC isn't comfortable in Prime 95 you probably shouldn't be running it there, even if you will never pin your CPU usage.

 

I have my i5-8600K at 4.5 All Core (100MHz bump over single core turbo, iirc). Hits 80c after a half hour of Prime 95, stays ~50-60c in game.

 

Now, I play GPU bound games. My CPU isn't used much more than 40%. I could run it at 5GHz rather easily (I know because I did), but it hits TJM (Thermal Junction Max) almost immediately in synthetics.

Download v26.6: https://www.mersenneforum.org/showthread.php?t=15504

 

It was the last version before adding AVX. 

 

Then run:

OCCT: A good CPU stress test using AVX with manageable temp

RealBench: Stress test for CPU and GPU at the same time.  A good test for thermals and stability.  Also uses AVX.

AIDA64:  Another CPU stress test using AVX that is pretty good at picking up memory errors.

 

If you can run those for at least an hour each, you are pretty damn stable.  After that, I like to let prime run for 12hrs overnight as a last catch all for instability.

I agree, to an extent.  When Prime95 hits small ffts with AVX enabled, it is more like a power virus.  Unless you are running Matlab or a few other science specific programs, you will never see a load like that.  I still run it, but I don't blame people that don't.

 

If he can run the stuff I listed above with reasonable temp (mid 80s) temps, he should be fine imho.

Well... I actually use Matlab, so I may be advising cautiously. I also validated my OC with Small FFT's+AVX

ok, i will do this but before i do this, can you tell  me what settings to set for each of these as i am still pretty dam new to these programs.

Run "Blend" in Prime95, "Small Set" in OCCT, set the memory to what you have in RealBench, and defaul in AIDA64.

I don't use Matlab, but I do run Small FFTs+AVX...because I am a glutton for punishment and I like to push my hardware.  I actually was just running it about an hour ago.  9900k 5.1GHz no avx offset...I fired it back up just for you. 

 

262 watts and not throttling is a win in my book...lol...

o, so no small ftt's for prime95, and whats default for aida64?  cause theres like stress cpu, fpu,cache

Blend will still run small ffts, it just will not hold them there indefinitely like when you select to only run them.  Run the CPU test on aida.

AIDA64

Tick  CPU, FPU, CACHE, RAM

All together.

Ram will fill to 90-95% and let it sit here using 100% of all CPU subsystems in a sense..

 

Also. Side note.

Something never mentioned. When AIDA64 Stressing, RAM is ticked, and now full... Detick RAM and watch CPU temps climb a little further.. Something Youtubers either miss or don't mention yet I've seen it do this on multiple systems.

Interesting.  I am going to test this.
