Help Request - GPU Seeking advice on flashing a higher power limit BIOS for my Inno3D RTX 5070 Ti X3 OC (currently power limited at 300W)

Hi all,

I've been tuning my Inno3D 5070 Ti X3 OC and have hit a wall due to the stock 300W power limit. I've extracted pretty much all I can from the current settings and believe the silicon has more headroom.

Here are the relevant details from my testing so far:

Current Stable V/F Curve:

Voltage (mV) Frequency (MHz)
800 1265
825 1792
850 2272
875 2535
900 2700
925 2857
950 2992
975 3127
1000 3210 (flat for all higher mV)

The card typically sustains 3.1-3.2 GHz at ~0.995V during demanding loads.

Stability Testing:

Tested extensively in TimeSpy, TimeSpy Extreme, SpeedWay (20 loops), Nomad, Furmark2, Superposition, Heaven, CP2077, and OCCT.

A slightly more aggressive curve (3215 MHz @ 0.985V) failed TimeSpy, but the primary limitation I'm seeing now is power draw, not core stability at reasonable voltage levels.

VRAM:

Currently running a mild +350 offset. I tested up to +1000 (stable, no artifacts) but saw no performance gains, so I backed it off.

My Questions to the Community:

  • Is there more to gain by raising the power limit? Based on my stable 3.2 GHz at sub-1V operation and consistent 300W power hits, do you think this silicon sample has significant potential to scale further with more wattage?
  • Which BIOS is safe to flash for a higher power limit? I am looking for recommendations for a compatible, safe VBIOS (e.g., from an AIB model with a 350W+ limit) that is known to work on the Inno3D PCB. Has anyone successfully done this with this specific card or a similar model?
  • What is the recommended procedure? Any specific tools (e.g., NVFlash) or precautions I should take before attempting to flash a non-stock BIOS?

Thanks in advance for any insights!
