The SINGLE gpu horse race at e@h

Happy Friday again!

After tweaking the memory clock 11 days ago, the old horse RAC has gone up and passed 3.2M PPD mark for the first time. It will probably take 2-3 weeks more to reach the theoretical RAC of 3.4M plus change.

At one point, I was thinking of pushing the old horse to the max but to hit that max RAC I'll need to run for another month. This will certainly increases the noise, temp and power consumption.

Here is the current instantaneous temp and voltage for the old horse. The power fluctuates from 165 - 180W mostly. GPU voltage at 0.85V, clock varies around 1450MHz.

amdgpu-pci-0300
Adapter: PCI adapter
vddgfx:      850.00 mV 
fan1:        2012 RPM  (min =    0 RPM, max = 3850 RPM)
edge:         +64.0°C  (crit = +100.0°C, hyst = -273.1°C)
                       (emerg = +105.0°C)
junction:     +82.0°C  (crit = +110.0°C, hyst = -273.1°C)
                       (emerg = +115.0°C)
mem:          +74.0°C  (crit = +94.0°C, hyst = -273.1°C)
                       (emerg = +99.0°C)
PPT:         168.00 W  (cap = 250.00 W)

In theory, if I were to use this Radeon VII overclocking guide, it is possible to increase the board power draw to ~300W and clock speed of 1800MHz+. Theoretically, this will push the PPD from 3.4M to 4.22M PPD (+24%) just based on clock speed. Power draw will increase substantially by 67% (180W peak → 300W peak).
