Radeon VII performance

Hi Guys,

  Does anyone have any experience with overclocking Radeon VII? My card is not giving me a performance that I am looking for. My cinebencz scores are not great at all somewhere around 8700 on 3D Time Spy and 4192 on Time Spy extreme. My config is as as below:

 

MB: Asus Maximus XI Extreme

CPU: i9 9900K (On custom liquid cooling, 420MM Radiator)

RAM: DOminator Platinum 64GB @ 3200 MHz

Storage: NVME Samsung 970 EVO PRO

PSU: 2000 Watt EVGA

GPU: Radeon VII

 

Currently I am stuck at 356 MHz on Memory clock... is this normal?

With such a bad benchmark scores I am not sure if I have something wrong here?

 

Any help will be deeply appreciated. I tried doing it using AMD Radeon settings utility, global wattman but with no luck, my system completely freezes on clicking save when I try even the Automatic OC mode... Please help it's getting so frustrating...

Radeon Vii, Ryzen 2700x, Asus ROG Crosshair Vii Hero, Corsair AX1200i Watt.

No, not normal. Double Check the metrics in Radeon Settings, does it stay like that through out the session or benchmark? 

Also, is ( Xbox DVR / Windows Game Bar ) turned on in your system.

The utility very rarely crashes on me but only once when I clicked save. I suggest clean installing the driver.

I only used the Radeon Utility. I made a manual Undervolt + Overclock profile. 

Stock voltage 1075 mV, manual undervolt to 989 mV
Edge Temp went down from 75c to 64c
Junction temp from 105c to 88c

^ No overclock + manual fan curve ( max 59% / 2750 rpm ) when hitting 85c Junction temp.

Now, my overclock:

- Core frequency from default 1802 to 1840

- HBM frequency from default (Auto 1000) to 1150

I got about 3-5 fps extra in games but I reverted back to default clocks, not worth the extra heat and fan noise. I can boost the core frequency to 1870, but I have to raise voltage but again, not worth it to me. 

even the Automatic OC mode

Unfortunately, with Auto Overclock, we can't adjust voltage or fan curve. So it's running at high voltages and the last two high points in the auto fan curve settings are, 60% at 94c and 75% at 105c.

For reference, 58% is 2750 rpm.
