overclock question

[kousant]

i have i5 6600k

asus z170-a

16gb ddr4 2400mhz

 

through asus ai suite it auto overclocked to 4.4ghz with auto vcore(max 1.280) and max temperature 60c after 3 hours of cpu-z stress test

the uncore ratio is 35 should i increase it to 43 ?

(the cpu downclocks when it is not used at 100% , does the uncore ratio downclocks with core ratio ?)

Don't use AI SUITE III. Delete it immediately. My PC keeps restarting because of it. Overclock it manually. Overclock it in BIOS like everybody else. Set voltage to 1.3V and increase core clock until temperatures are not right or until you crash. If you crash lower the voltage. Repeat until you reach comfortable temperatures as well as core clock. I'd guess you'll easily be able to get 4.6Ghz.

I wouldn't use AN overclock in suite to overclock. Just overclock through bios. What cooler do you have? With something like a corsair h100i on your CPU, you can easily achieve 4.5-4.8 GHz. Push your core clock up till you get a crash, then push up your voltage by 0.025 volts, with 1.3 volts being the MAX I recommend. Once you up the voltage, keep pushing up your clocks. Rinse and repeat until your thermals are bad (I recommend no higher than 80 degrees Celsius) or until your system is unstable no matter what you try, then go back to your last stable settings. As long as you don't push your voltage past 1.3, you shouldn't screw anything up. ?

I wouldn't set your voltage that high unless you have a proper cooler. An h80 or h100i is about right for that voltage.

Thanks for the responses , I am using a raijintek themis 

Except from cpu-z stress test , is there any other free program to check the stability ?

Look up Intel Burn Test, run it at maximum (It will use all of your RAM or most of it) for 10 passes or more (I usually do 20). If your CPU didn't crash, it will be stable in everything else. Do note that Intel Burn Test runs super hot (It's brutal on the CPU), pretty much any normal workload (even at 100%) will run cooler than Intel Burn Test.

 

It might crash on the first attempt starting the program and windows will bug you that you need to install a older runtime to run it, after installing the needed runtime, Intel Burn Test will work just fine.

I enabled xmp , oc my cpu to 4.4ghz with 1.250 vcore max temperature 50c 

And oc my ram to 2666mhz 

Is the oc safe for my ram and cpu?

I have the Kingston hyper-x fury 16gb 2400mhz 

 

I have left core cache ratio at auto should I change it?

It sounds safe, but what matters more is that you need to make sure it's stable...have you run Intel Burn Test?

i used realbench's stresstest for 30 minutes , max tembs was 58c , at cpu-z and hwmonitor the cpu was running at 4.4ghz but at task manager it was showing as 4.34ghz

Yeah, I wouldn't trust task manager for clock speeds, it's been crazy off at times for me. I think you should run a stress test for a few hours at the minimum.

I have 6800K. I can go 1.4V. My old 4790K ran at 1.3V 5.0Ghz.

1.4 volts is actually above the pay-grade of 14 nanometer transistors. be careful! You're significantly affecting the lifespan of your hardware and risking electric interference with such a high voltage.

I like prime95. It pushes your CPU to the absolute limit. It is synthetic, so if you overheat in prime95 it may mean nothing, but if you don't overheat in prime95 you're definitely golden.

Nah it's fine, temps are okay and core clock is also pretty good.

although the temps are fine, that much voltage will physically damage the CPU if you aren't careful. Your CPU will not last nearly as long as a CPU at 1.3 volts would. I don't speak from knowledge of the X99 platform, but I speak from an overclocking knowledge standpoint. Out of curiosity, what clocks do you get at 1.3 volts?

Please look up overclocking for 6800K.

 

I was getting 4.1 / 4.2 on 1.3V.

That's very interesting. Actually seems pretty common among 6800k's. Should I be worried about sending my 4690k up to 1.4 volts? I wanted to push to 5 GHz but could never get it on 1.3 volts.

1.3V is what I call maximum on quad cores. Six cores have more cores and they're not as powerful as quad cores so the temps are lower, therefore I can go little crazier with voltage.

 

Overclocking allows me to match quad core speed, but with 2 extra cores, so multi threaded applications are 30% faster for me.
