I recently bought a new graphics card (MSI 5090 Suprim SOC) for LLM. I've never undervolted it before. Can anyone verify if I've done it correctly?
It was showing around ~590 watts at stock.
After undervolting, I got ~550 watts under load, 0.9 mV at 2900 MHz. Memory +2000. Max Temp 78C
I can lower it to 0.875 mV at 2800 MHz and get ~520 watts.
But I like the current performance; I'd like to push it even further. But I'm worried about cables and melted connectors.
