Hi, I just changed, voltmod on my 8kha+ from 200kohm resistor to 100kohm pot. My new lowest voltage ~2,2V. Then I Oc my D600 a little more to 1105@2,22V (6.5*170) which is ~95W of heat from 30% smaller core than axp, and with this new block I'm getting 8°C above water temp full load. Which result in less than 0.1 C/W for my watercooling setup
