Haswell Stress Test

[tuberolector]

I just got a Core i7-4790K, and before I start overclocking it, I need to know how to stress test it.

I have heard that you should not use Prime95 with Haswell, so what should be used?

Thanks for any help you can provide.

[Katsu-K1L]

Use prime95.

and i suggest you use intel extreme tunning utility, here:

intel burn test.

[i_build_nanosuits]

you could use other stress test than intel extreme tuning utility but if you do make sure you are on MANUAL VOLTAGES for your CPU, the other stress testing tool all will apply additionnal voltage and sometimes A LOT more than what should be applied and your cpu will run too hot and you might even kill it if you,re set on variable voltage...

Use prime95.

No, don't use Prime95.

 

Use intel burn test.

I used prime95, terrible idea. My bios does not seem to be able to manually lock my voltage so prime overvolts it dramatically. Use intel extreme tuning utility. It will not overvolt your cpu and it is very reliable as it made by the same people who made your cpu

exactly this, Intel XTU also has temps and volts monitoring built in...its really a fantastic tool, you can even test your ram stability with it in a separate test...it's awesome.

So the Intel Extreme Tuning Utility won't apply additional voltage, no matter what the setting is in my BIOS?

@tuberolector

i use XTU or OCCT 4.4.0 for haswell. monitoring of temperatures and voltages is

really kind of nice, instead of having 5 other appz running doing the same thing.

 

no need in 24/48hr burn in. a simple 15-30min sample and then real-world usage.

yup, thats how i do it as well...i run 15-20 minutes of CPU stress test in intel XTU and then 20 minute RAM test in intel XTU, and then i use cinebench i run a couple of pass... if no failure then i play games and use computer normally and see.., but its usually stable if it wont failed intel XTU and cinebench a couple pass...

Using XTU, how high can my temperatures be before it is considered too hot? I know that for older CPUs the could use Prime95, around 85 degrees was as high as it should go, so is it the same when using XTU on Haswell Processors?

i would say if you get in the 80's with the intel XTU CPU stress test then this is your max...the memory test will run you some degrees more...but usualy anything bellow 80c is fine because when you play games and do normal daily stuff on your PC it never gets that hot anyway...but 90c is hot for real and 95c is when the CPU start throttling itself down.

 

Personaly i run a core i7-4770K at 4.4GHZ with 1.2volts on the core with only a air cooler (hyper 212) and XTU run's at about 65 to 68c max...th 4790K being an improved 4770K it should run even cooler...unless you pass 1.35v or more through it or use the stock cooler i won't think you'll have any heat related issues.

[airdeano]

it is just me, but i use a threshold of 90° for bonsai clock runs. for stability testing use

an 85° core cut-off. in RW usage, it'll never get that toasty so it builds in some heating

headroom for security.

 

instead of multi-searching, i'll run up the voltage to 1.35v (stock multi) and see what

the temps are in that scenario (using aftermarket cooling, NO STOCK COOLERS).

if the temps are too warm, back off the voltage to what you consider acceptable.

once you find that "voltage point" then move the multiplier up.

 

highest multiplier and unstable, back multiplier to last known stable run and reduce voltage

till unstable and retest last known good voltage and now you have an acceptable temp to

voltage overclock.

I would say don't pass 85C on the intel burn test, you only need to remember that whatever a burn test does to you cpu temps wise you will probably only reach 90% of the temp in real world usage (so roughly 77C) And personally launching multiple games at the same time was my real test. I could run games all day but I would crash when launching multiple games until I made a slight voltage bump.
