Hello Guys.

I really need help im done .

The Card is new and i bought it from Alternate.

1 XFX 16GB RX 6900XT Merc319 Limited Black / SN: 1 x WXV041045 - Is the listed document from Alternate.

So my problem is, the Card does not boost Properly, like the Card boosting very inconsisten and i think it got the Wrong bios, cause when i Put GPU-Z on it says that:
So GPU Z Shows me this card: https://www.techpowerup.com/gpu-specs/xfx-speedster-merc319-rx-6900-xt-black.b8675
but thats not the limited black edition, but the limited edition bios is like fucking up my perfomance.

(LITTLE QUICK INFO - IF I PUT THE BIOS SWITCH TO POWER IT SAYS THIS BIOS VERSION: "020.001.000.060.000000"
IF I PUT THE BIOS SWITCH AWAY FROM THE POWER CONNECTORS: "020.001.000.046.000000" )

I Switched Bios and it was a bit better but way under the Perfomance what it should like, it just draws a Power usage of like 250 Watts, normally its like 330-350.

Whats wrong with my Card? i think thers a Bios problem where the card really dont know anymore when to boost or maybe its the wrong Freq. cauz its throttling. With my main bios sometimes i have like in Farcry only 80 Watt usage and poor performance on the Normal Bios which goes to the Power Adapter.

Little info to my System:

Asus TUF X570 Plus WIFI
Gskill 4000 Ram - running on 3800/1900.
my GPU as above.
AMD Ryzen 5800X3D
Running on Windows 11 with Rufus optimized. No Secure Boot. No TPM

Those 2 cards (black vs black limited) have a different gpu core. They are not the same card. One has the Navi 21 XTX chip and the other Navi 21 XTXH. One bios you have is for the XTX and the second for the XTXH. If you bought the card recently and was described as brand new, return it and do not reflash it/open it etc. If you can't return it, you need to find out what variant it really is so you might need to open it to see the engraving on the chip.


The engravings:
XTX variant: 215-121000167
XTXH variant: 215-121000247

I hope there is an easier way to tell them apart like cooler differences or the number of power connectors but I don't know for those 2.
