Grabbed a Powercolor version of it and put it to work folding to test the card.

Have some tuning to do, it did crash while doing this but almost finished it (94% completed).
Temps overall since have dropped some as if the factory TIM is breaking in with the card.

I completed the build with EKWB on the Radeon VII. :D

Started working on the optimization of performance versus undervolting.
My Card's default setup: 1802MHz @ 1084mV

Currently I was able to tune it to 1870MHz @ 1052mV.

Below is the Firestrike Ultra Stress Test.
During Stress test maximum GPU temperature 44°C and Junction Temperature Maximum of 74°C. :peace:
Considering that mine was hitting 110°C on junction all the time where it started to throttle. This is really great.
Under normal GPU loads the junction temperature stays below 70°C and GPU temperature below 42°C.

GPU frequency was staying most of the time between 1820MHz-1855MHz going time to time to upto 1870MHz with an average of around 1838MHz.

More result will come in the next days....

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:
FireStrike_Ultra_Stress_Test_Default_Setup.JPG


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. :D
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. :twitch:
Next I will do some gaming to check that this setting is also stable in different games.

Playing currently Metro Exodus. :rolleyes:
