OC i7-7700k to 5GHz, ASUS Z270G, everything seems stable but Prime95 ?

[Kenrou]

I remember we discussing this ad nauseam in other threads, most people have issues with Prime95 because they seemingly have no idea that different versions run different types of AVX. Up to 26.6=no AVX, up to 27.9=AVX 1 (most common, same as all the other stress tests), up to latest latest 29.3=AVX2/FMA3. There was also commands that disables the different types of AVX inside Prime95, file called local.txt, so you can just use the latest with all the bug fixes, i think it was Wingman99 that asked about them in the mersenne forums.

Pointing out that only the most heavy workloads like science/weather/x265 encoding actually use AVX2/FMA3.

CpuSupportsAVX=0
CpuSupportsAVX2=0
CpuSupportsFMA3=0

I found out with this latest CPU that when I'm benching at 5.4 GHz with 1.425v, it can and will set the temp alarm off. Had to do some upgrades to my loop. It happens. It's all good now after adding some capacity.

What's your point here?

HI Trents.
My point being my first intel rig gets hotter than expected on auto config settings.
Also was my first stability/benchmark testing.
Also have not run cpuz yet.

Other than that the system has run excellent on auto settings.
I have not benchmark a comparison yet on scoring example... chinebench15.

yup, i discovered all this info through some google searches as well.

but I'm content where I'm at. I'm sticking with 5GHz (non-AVX loads) with a AVX offset of 1 for 4.9GHz when AVX pops up at about 1.325v. it's fine for me.

definitely super stable. i literally ran this thing for a week straight encoding blu-ray and DVD rips with Handbrake (AVX). not a single crash or hiccup.
ran 12+ hrs of prime with and without AVX

I don't know man..need to find some more guides and mull over it all. seems to be and looks like this decent voltage jump past 4.8ghz... about 62-65c decently loaded with the d14 and pretty botched rigged mounting lol...level of destroyer on AIRRR is terrifying man.

how much voltage are you needing? like i said, Im at 1.325v for 5.0GHz and thats a very reasonable voltage level.

Old thread, but it is worth mentioning that ASUS RealBench does a pretty good job of stress testing. I found that handbrake is pretty good indicator of stability (integrated with Realbench).
