It doesn't matter as long as the PC is off. Just hold it down for 5 seconds.

They're from bodily fluids.

I have replaced the thermal paste with thermal grizzly kryonaut. The washer mod achieves the same thing as filing down the posts, more mounting pressure. The SOC voltage limit is set as 1050mv by default but the max I've achieved is 0.934mv, also the max SOC power draw is only 9.725w so lowering it further would only give me a couple of watts at most. My max core voltage is 1.058v which is what I have set in Adrenaline, it's the lowest voltage that the card is stable at a clock speed of 2637mhz.

What kind of a design is it? What are you going to make it out of?

I have a 6600xt that I have overclocked, under high load it becomes power limited even at +15% power limit and clocks down. I cannot increase the power limit any higher as the GPU hotspot temp reaches 99C in games and I don't want it to go any higher. It was even worse before, the difference between GPU temp and Hotspot temp was 60 and 110. This was due to poor mounting pressure as MSI's tolerances for the cooler are garbage. I filed down the main four screw posts to increase the mounting pressure and now it's much better. I also took off the plastic blanket called the backplate. I know it can perform a lot better, if only I could push more current through it. To do this I want to mount a ducted fan to blow air on the back of the card. Maybe a 50mm EDF for RC aircraft. I want to know if this would significantly affect the core temperatures of the card and will it allow me to give it more power.

So you must be willing to run games at 720p 15hz right? In which case you are grossly overspending.

I finally managed to do it after trying a few things. What worked was setting the SOC voltage on the main "tweaker" page to auto THEN going into the AMD overclock settings and changing the SOC voltage. The cpu (SVI3 TFN) sensor on HWinfo and Ryzen Master both now show the correct SOC voltage and the motherboard sensors show about 30mv above that. Also I may have won the silicon lottery as I managed to lower the SOC voltage to 1v flat, boot into windows, run OCCT memtest and get errors. Right now it seems stable at 1.05v.

I just set the SOC voltage as 1150 in the AMD overclocking menu but HWinfo is still showing it as 1.2v and so is Ryzen Master.

Got it, will try that now. I am on the latest BIOS.

Should I try setting a negative offset for SOC voltage in the AMD Overclocking menu in the BIOS?

After setting my memory to the EXPO profile, I manually set the SOC voltage in the BIOS to 1.05v fully expecting it not to boot. Planning on gradually increasing the voltage until the system was stable. But it booted into windows straight away, the memory running at EXPO speed. In HWinfo the motherboard sensors show the SOC voltage at 1.08v and so does the BIOS but the CPU sensors are showing the SOC voltage as 1.2v and so does the AMD Ryzen master software. So what is my actual SOC voltage?

The second pair was just running at the 1.2v non XMP profile, if you have now set the voltage to 1.35v set them all to the faster 16-18-18-38 timing, should work.

Only change the CAS latency, Trcd, Trp and Tras. Leave everything else to auto, when you start your PC it will reboot a couple of times, give it anywhere from 2-15 minutes and let it reboot, it will be training the memory and trying to figure out the rest of the timings.

Just change the speed and the timings manually, if you put in the part number of your RAM into google it should lead you to a spec sheet where it shows the default and XMP profile timings, speed and voltage.
