To stresstest the CPU I am using OCCT with Medium/512mb/No AVX.
Furmark for the GPU and MemtestPro for the RAM.
Safe voltage: 1.425v when kept under 75C.
Messing around with the Athlon CPU I found that this chip seems to do 3.9Ghz at 1.3875 vCore. 4Ghz needs more than 1.4v which my case and wraith stealth will not keep up with. A bit of a bad chip it seems. Many seem to do 4Ghz below 1.4v.
Since both create a bit too much heat I tested what 3.8Ghz needed and ended up only needing 1.3 vCore.
I haven't tested the stability during high load for hours or anything but I am confident this'll stay stable.
Sticking with that as my CPU OC.
Next I tried getting some more juice out of the iGPU. This was very new territory for me.
Set SoC to 1.2v as it seems to be the standard maximum.
Tested by running furmark for a while and looks like its fine at 1600Mhz.
Tried running both OCCT and Furmark... and it gets too hot but thats a crazy intense scenario. Doubt it'll get that hot in a real scenario.
Running a 3dmark Night Raid stability test passes with much less temperature.
Got both the CPU and GPU at relatively safe overclocks that I can't push more. Time to get the ram either with tighter timings, or faster speed.
I either got lucky or Gskill are just nice. My sticks of ram are B-die. This should allow pretty nice overclocks.
1usmus program is helpful but I either can't read it properly or my ram is not good enough because none of its settings seem to work for me.
I instead tried different speeds on the XMP timings with 1.4v to see how far I could go.
I'm not very good at RAM OC.
3266 @ 16-18-38 is stable and I'll just use that.
Final Night raid results after overclocking.
