Hi there,
First of all, don't rely too much on Prime95. It creates unrealistic loads that you don't need to pass without crashing for a full use of your rig. I now prefer to use ADA64 for 30 min at a time as it is a lot closer to normal use and have no problems ever.
I am also using dynamic voltage by setting VCore to "Normal" with an DVID offset of + 0.080 but that gives me VCore of 1.320 V, +0.085 gives me 1.322 V, and +0.090 gives me 1.392 V (you can keep going up to see what yours gives you. But that's more to save on the voltage in comparison to static voltage.
This was a long time ago, but here are some more of the settings I recorded. There might be something in there that will get you forward... worth the trial ;-)

=====================================================================================
Try running OCCT, as said above, Prime95 might not be the best utility for stress testing CPUs. If you really want to use it, I'd recommend editing the files and disabling AVX instructions.
Using hwinfo to monitor temps , got 4,6ghz at 1.395v now testing with occt , temps on cpu seems good - max
75° , but there is a temp called
VRM that goes up to
125° when testing OCCT large data set , is that normal ? At 1.215v 4,2ghz goes up to
105-110°.
Also if i let
vccsa and
vccio set to auto they go up to
1,35v which i read is way too much , that maximum safe voltage would be
1,25v.
My bios settings are :
[1] - CPU Core Ratio: 46
[2] - FCLK Frequency For Early Power: 1 GHz

[27]-CPU VCCIO: 1.10v
[28]-CPU System Agent Voltage: 1.10v
[29]-PCH Core: Normal
[30]-DRAM Voltage (CH A/B):
1.320v - HWINFO says max 1.308v
[31]-Internal Graphics: Disabled
Also testing stability in Aida , wich test should i check? Stress CPU , FPU , CACHE , System Memory?
Just finished 30 min of Aida stability test with cpu , fpu , cache , system memory checked , no problems , max cpu temp 69
° and vrm 94
° .
On other hand occt large set is crashing after 8 minutes or so , and detects 870 errors.
