I forgot to mention above. I am using Thermal Grizzly Kryonaut for thermal past.
The back side of the card is covered with EKWB black backplate which contacts a number of components on backside of GPU with thermal pads to help with cooling.
As mentioned in above post, my Card's default setup: 1802MHz @ 1084mV
With this setting, average clock frequency after a run of Firestrike Ultra Stress test is 1768MHz and average full system power consumption of 410W.
Maximum Junction temperature 73°C and max GPU temperature 43°C. Room temperature 22°C.
Stability test with default setting:
I went up with the Frequency to 1901MHz @1074mV.
This way achieving a stable overclock while still in under volt condition compared to default setting.
Average clock speed after a Firestrike Ultra Stress test 1860MHz.
Boost clock going often to 1880MHz and sometimes up to 1900MHz.
Average full system power consumption during Firestrike Stress test 425W.
There were a couple of power spikes in range of 470W during measurement.
Peak power spike recorded was 499W but this was only recorded twice during the whole Firestrike run.
For me these are not a problem. I have a Corsair HX1200i 1200W supply, but these can cause PSU to enter into overcurrent protection shut down if somebody has a week supply.
My Vega 64 used to have such spike also.
Maximum Junction temperature 74°C and max GPU temperature 44°C. Room temperature 22°C.
For 15W of more power, I get around 92Mhz higher average clock.
If you compare the stress test, my Radeon VII seems to be more stable having 99.7% frame stability at this overclock compared to 99.3% at default settings.
Next I will do some gaming to check that this setting is also stable in different games.
Playing currently Metro Exodus.
Firestrike Ultra Stress test for 1901MHz @1074mV.
TimeSpy Score for 1901MHz @1074mV.
Firestrike Extreme score for 1901MHz @1074mV.
Superposition score for 1901MHz @1074mV.
