I9 9900k overclocking stress test questions

[BerserkHealer]

Hi all,

 

So i want a few questions answered, y is it that i can get a stable overclock with a lower voltage using aida64, then when i use prime95.

 

Aida 64 i can get 5ghz at 1.3v but i think i could get but still testing... all my cores are 100% and staying there and no crashes... and avx is at 0 and temps are about 80-84 max on 1 core 

 

When i use prime 95 i have to put on a avx offset at 2 and my voltage is about 1.34... to get a 0 avx i have to go higher and my temps are round the 95- 100 mark

 

What i want to know is whats the best way to make sure my system is stable for gaming i dont do anything on it other then game and watch films 

 

Are these temps to high? And i want to know if there is a way to get my temps down and still have the avx at 0

 

And i want to know is it better to have the oc stable from prime or aida?

The CPU has a TJ MAX so at once point usually around 100c the computers shuts off so the CPU doesn't die.  The TJ Max if Im not mistaken is like no higher then 110c on any cpu let alone a premium CPU.  Your reaching temps where the computer will shutdown, and your getting lucky.  What can we do to lower your temps to 70's c when gaming ?  What cooler do you use ?

I use prime 95 26.6 for stress testing, because it is the last version without avx

[BerserkHealer]

I am using a custom loop, 2 240 rads and 2 140 rads.

 

And i just used intel burner and my temps was about 55-60 ... lol 

 

But for some reason to have avx at 0 on prime i need alot more voltage... 

 

Do i need to get my system stable on this? To class is as stable?

Ill give it a try thanks

And atm just running aida 64.. on 1.275 volts... gonna see if i get a crash... but 100% on all cores

At the end of the day Prime95 is a synthetic test and your real world temps will be at least 10c more with it, compared to Aida64 stability or gaming for that matter.

Last time i was messing with my oc i got my voltage down to like 1.29v with aida 64... but then when prime 95 it took me way high did think it was odd... just trying the version mephi said and its going good so far on 1.275... ill keep trying to lower it... temps atm 76- 84 max

Might be wrong, and totally my thing to do when OC'ing,but I only take Prime 95 to do a quick check if the voltage / temp is okay and no core gives up. 
Then i test my OC with multitasking, gaming and stuff, cause that's what I am using my PC for. 
For example OC'ing my 5 2600 i opened some youtube tabs, started streaming, started Itunes and played a few rounds of BFV and ApexLegends.
That kind of testing works for me.

Using prime 95 26.6 i have gotten my voltage down to 1.235 v and temps 75

for gaming only i'd use cinebench/aida temps (under 85C is good imho, personal preference), if you are getting 75C in prime it's probably the wrong test (but it doesn't matter either way)

You really need to use non-avx prime 26.6 to stress test your CPU, it's load is beyond what regular avx apps put on the CPU, or simply use Aida 64.

 

I think the 9900k got such a bad rep because people are testing it with prime 95 avx, which is Ludacris. Even my 6900k is getting over 90 degrees on prime avx, while during regular avx tasks, I'm at 75 (package). So please people, don't use prime 95 with avx.

 

Don't even try to run prime 95 avx with x299 CPUs, they'll hit 100 degrees easily, worst offenders.

No he's doing fine. People are running prime avx, which is not a realistic workload. It'd avx instruction hammers the CPU beyond what regular avx software does. Prime 26.6 non-avx is the best real world avx tasks because it already stresses the CPU at an avx software level. Prime 95 with avx is just there to kill your CPU with a load that's utterly unrealistic.

non avx is even lighter than real workloads, and avx small fft or max pow is too hot

Lighter? I've never had that issue and I've been encoding Videos / working with Pro Audio. I think people generally overvolt the 9900k and with that run into instability. Well, I guess I wouldn't want to go beyond 5 GHz anyways because the merit vs temperature and power consumption is too damn small. But as soon as someone sees people hitting 5.2 GHz, they want to have it, even if that means 1.4 volts but complain about high temps. They can't compare it with the older chips from 3 years ago, so can't you the x99 with x299.
