inquiries regarding OC i5 8600k aorus gaming 5 mbo
Hey guys!
So the last few days i've been oc'ing my cpu and i'm having some trouble finding the right settings, this is my first time oc'ing and i'm getting stable clock's but still not sure about the few settings.
I'm having a stable overclock at 4.8 ghz @ 1.315 Vcore with prime blend test temps not going over 78C for around 2 hours ( going for longer periods after some advice). Uncore ratio 45!! AVX offset 2
While testing my vcore voltage goes as high as 1.31 and 1.14 lowest. underload the vcore is around 1.20.
Now the thing is i have a setting in my bios called:CPU Vcore Loadline Calibration /cpu internal AC/DC loadline.
I have notice the CPU internal AC/DC loadline doesn't do anthing.
The CPU Vcore Loadline Calibration on the other hand does alot to my Vcore spiking and i have Auto/standard/high and turbo settings.
Now the thing is when i put that setting on high i can put my CPU Vcore voltage to 1.28 and be stable...BUT my voltage spikes to 1.34 and doesn't go any lower then 1.24 ish..
BUT my Temps are going way over 90C and max 97C...
So even tho my overall voltage is lower my temps and spikes in voltage are still higher.
Now the gab between 4.8ghz and 5ghz in voltage i find way to much.
When i wanne aim for 5ghz(Uncore ratio 45!!AVX offset 2) on the cpu without the loadline calibration i have to put Vcore about 1.37 to let prime not give me erros withing few minutes, now again when putting the setting to high or tubo i can be ok on 1.3 Vcore but temps are just redicelous..
All the other power saving features on my mobo are all on auto..speedshift and all the C stuff....
VT-D disabled
Could it be that my psu is underpeforming or my mobo is just bad?
Or Should i just stick with my 4.8Ghz settings?
Specs:
GPU G1 Gaming gtx 1080
Aorus gaming 5 MOBO.
CPU i5 8600k Be quiet dark rock pro 3 cooler.
Memory G.Skill DDR4 Ripjaws V 2x8GB 3200.
PSU G650M Cooler master.
Case is Phanteks enthoo Pro M
EDIT: I have now stable 4.8ghz overclock with different setting.
I have the CPU Vcore loadline calibration on HIGH .
cpu 1.230V 4.8GHZ uncore 45 AVX 2
Vcore MIN 1.18 MAX 1.25 under load 1.19-1.25
temps max 80
So with these settings i have now a lower overal Voltage but a light increase in temps.
But having a lower overall voltage is in my opinion the better option?
Cheers.

When AVX applications aren't necessary for rendering or transcoding, setting an AVX offset isn't worthwhile just to ensure stability. AVX can be turned off in Prime95 versions after 26.6 by adding "CpuSupportsAVX=0" to the local.txt file. But since core temperatures remain the same, it's simpler to stick with 26.6. If you run AVX applications, configure your AVX offset so that Vcore, Power (Watts), and Core temperatures in P95 match those without AVX. A 4 or 5 might be required to keep core temps stable. Refer to the sections listed.
When evaluating your CPU with Prime 95 it is advised to perform small FFT tests. The Blend test mainly checks memory performance and does not accurately reflect the stability of your CPU overclock. It is also suggested to use Prime 95 version 26.6, just because AVX instructions are absent.

thanks for the answer!
i've been running bot versions for 8 hours without any issues.
current clock is 4.8ghz at 1.230v llc high (second highest setting).
when using Prime 95 version 26.6 my temperatures only reach 74, while the other version gives around 83.
for the 5ghz clock i don't have the right settings yet, but with avx version in Prime 95 I'm seeing temps above 90 at 1.30v (still not stable), though maybe i should try Prime 95 version 26.6 first.
i'm using both overclocks: avx 2 and uncore ratio 45.
what do you think?
