Hello,
I have this PC setup:
Ryzen 5 3600x
AMD 6700XT Hellhound + RTX 3060 Asus Dual-fan
Asus B550 Tuf Gaming Plus
Corsair Vengeance LPX 3600mhz
ADATA XPG SX8200 PRO
Corsair CX750M CP-9020061

When I run mine with two cards, the Nvidia performs at half its hashrate. I used the old drivers 470.05_gameready_win10-dch_64bit. I can achieve full hashrate when running solo, but pairing it with the 6700XT causes issues. I installed the drivers using DDU v18.0.3.9 and did my best. When using two 6700XT cards, everything works fine. I adjusted the BIOS settings without success. Any suggestions? Could be an AMD-Nvidia compatibility problem?
Thanks!

Monitor CPU and GPU performance using Task Manager. Focus on two sections: Processes and Performance. Identify the differences between the original GPUs (6700 XT) that achieve high hashrate and the new mixed GPU setup leading to lower hashrate. Note: Download GPU drivers directly from the manufacturer, reinstall, and adjust settings as needed. No third-party installers are allowed.

Use Resource Monitor to track system performance with the various GPU setups mentioned in your original message. Compare the "no problems" rate of the 2 x 6700XT cards, the individual GPU performance (per card), and the combined operation of the two GPUs.
PSU: Gather details such as make, model, wattage, age, and condition.
Check previous heavy gaming or mining activities.
Skip DDU.
Download drivers directly from the manufacturer's site, reinstall, and reconfigure for your PC.

PSU: Corsair CX750M CP-9020061 750 Watt 80 PLUS® Bronze Certified Modular ATX PSU
Recent model, excellent condition.
Used only for mid-range gaming.
Performed a few DDU installations and even set up a fresh Windows copy.

Do you have another functional PSU available for replacement in your setup?
Even if the PSU looks intact, its internal parts and wiring might be compromised.
If you possess a multimeter and understand how to operate it (or someone does), you can perform some checks on the PSU.

This isn't a comprehensive evaluation since the PSU isn't operating at full capacity. Still, any voltages close to or deviating from specifications should raise your concerns.
A single GPU might be okay with one PSU, but using two could stress it further and accelerate wear over time.

Hi,
I've tried it with two power supplies. Combined a Frankenstein monster with one connected to the main PSU and another using cables from a second PSU on a different PC.

Did, did and did. Im starting to be quiet sure that his is a drivers compatibility issue

It might be helpful to revisit using Process Explorer (Microsoft, free).
You could explore various GPU configurations to see which combinations cause issues.
This process is expected to require time and effort, as you'll need to analyze multiple scenarios to find a consistent pattern.
