4790K on 1.280 VCore @ 4.7 GHz. How safe is this? - Page 2

Thread Starter 
My god. 1.25V for 5GHz is beyond golden brah. 4.8 with 1.25 is gorgeous!

Also, when you say 1.25V, do you mean the VID, or the VCore at load? Because 1.25VID equals 1.280 almost at VCore with load.

volts in bios. And im not referring to 24/7 stability, because that has no real definition - some people want to be able to pass 24 hours of p95 while some are ok with just being able to play games. I'm referring to bench stable. Enough to run stuff like 3dmark11.

VCore also rises to 1.280 every once in a while during gameplay (once per 2 hours) to keep up with the extra load. Temps get to maximum 83C when stressing and maximum of 70C when playing extremely intensive games (usually no more than 60C though).

I've been told it's okay by some people. But others claim to be running at lower voltages (like 1.250) for safety reasons, and this frightened me a bit.

Is 1.280 safe? How much degradation will it cause? Will it lower the 4790K's lifespan? Are the temps fine?

Please reassure me guys. :S

Pretty sure most submissions in the haswell overclocking thread with statistics (look at the statistics! They're there for a reason!!) are using higher V than that

Hi, New to this forum. Iv just picked up a 4790k and so far Im able to get 4.7ghz @ 1.2 volts stable with XMP set at 1866mhz and uncore at 42 @ 1.2volts. Am able to run a few tests at 4.8ghz with 1.2volts but realy woundering if its worth it seeing as how benchmarks only went up by a fraction going from 4.7ghz. Temps sit around low 80's, cooled with kracken X60. What grade would my chip be?.

Very good, ~4.6 @ 1.3 is normal.

4.7ghz to 4.8ghz on the same voltage should only increase temps by like 1-2c max. Almost all of the power consumption (heat) change is from the voltage change - power rises to the square of the voltage, but only linearly with frequency.

2.1% performance gain for 2.1% power cost would be great. Tuned properly, you'd either need more voltage for 4.8ghz or less for 4.7.

You shouldn't be that hot with an x60 at only 1.2vcore (a low overclock) - what test are you running? Hows your cooler set up (which case position and is it set to intake or exhaust? what's your room temperature like)

4.8@1.2v os well above average, in the 5% top chips I'd say.

Is 1.280 safe? How much degradation will it cause? Will it lower the 4790K's lifespan? Are the temps fine?

Please reassure me guys. :S

Yeah whoever told you that ~1.265 - 1.28v or so was BAD has no clue what they are talking about. For example, my i7 5960X i overclocked to 4.5ghz at 1.3v vcore (have since been able to reduce to 1.28v if i go 1.95v input voltage, but haswell-e is a tad different so consult a 4790K guide about input voltage) for quite some time and its fine. A lot of people run their Haswell-E chips at 1.35v or even close to 1.4v all the time and are usually fine. On Haswell and Haswell-E you are USUALLY fine (as in not dangerous) at anything under around 1.45v. However for "long term" constant use, you want to try and stay below 1.35v or so. If you keep the chip below 1.3v it literally has near no effect on the CPUs lifespan; so at 1.265 - 1.28v range you are PERFECTLY fine.

The temps are perfectly normal too. 83C during stress tests happens, what is your cooling setup? Air? An AIO water? The only reason i'd be concerned about 83C stress temps is if you had a custom full sized water loop with several radiators etc.. on like a Corsair H100i or something or a 212 Evo etc.. 83C in stress if perfectly normal. Intel chips don't throttle at all until they peak over 90C temps anyway.

Rule of thumb, for 24/7 use, try to stay at around 1.3v or lower and 80C or lower max gaming load temps and you're ok. If custom water loop 1.35v is as safe as 1.3v since the water provides lower temps. Seriously though you're fine man.

Hi I'm new to the OC world.

I'm currently running my Haswell i7 4790k at 4.8Ghz max core voltage 1.28V.
Max temperatures recorded were 66C average of 51C.
I'm still trying to go lower voltage.

I have a water cooler H100i v2.

I tried to go to 4.9 and I got blue screen with 1.295V during the stress test.


Do you think I should go for 4.9 with higher voltage?
Or keeping at 4.8/1.28 is fine/safe?

Thanks!
