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:

Have not seen any posts in quite a while.. I take it everyone is happy with their Radeon VII? I know I still am plus no buyers remorse/guilt. Still happy I bought one. Seen many articles about EOL for it, but of course that is not support (this is still AMDs Flagship GPU for now) which I think will last for quite a few years.

I am also happy with Radeon VII. :)
It is still running strong.
I recently updated my system with Ryzen 3700x and ASUS Crosshair VIII Hero WIFI.

So what's the best water block available for the R V2?

Alphacool block is potentially dangerous and seems to not cool well.
Byski block seems to do ok.
EK block has the same-ish design as the Byski but thinner fins and seems to do ok. Only one with a backplate?

Then there's the Phantek's Glacier block it seems to have a massive active area, but there's not much talking about it. Beside the fact that it's their first Radeon block.

Curious minds...

Good that I cancelled my pre-order for Alphacool back in March. Hearing that this block is dangerous, I am glad that I went for EK block. :rolleyes:

With EK I had so far no bad experience. I used EK also on Vega 64 before with very good results.

I am very satisfied with it on Radeon VII. I have it since April and temperatures are very good.
In the summer where room temperature was in range of 27°C, the junction temperature on Radeon VII never went higher than 78°C.
With original cooler my Radeon VII was hitting 110°C after few minutes of gaming back in March where room temperatures were in range of 22°C.

With original cooler I ran it at default settings: 1802MHz @ 1084mV
Since I have EK block back in April, I run Radeon VII permanently at: 1901MHz @1074mV.

I have no problem at all by running it at this setting. I played many games on it since April. :)

Did any of you ever tried to get CrossFireX working via XDMA with two Rad 7's?

I still am thinking of getting a Rad 7 over the FX 5700 XT mainly that 16MB VRAM buffer can be helpful for long term usage., atm I am using a Sapphire Nitro+ RX Vega 64 LE 2.0 8GB HBM2.
Just a shame that there were no AIB versions for Rad 7, that is the only setback I saw with these cards.
