RTX 3070 CrossFlash guide for those aiming to push performance boundaries
RTX 3070 CrossFlash guide for those aiming to push performance boundaries
Warning: Flash vBIOS may brick your GPU. If you use the incorrect BIOS, a backup will be necessary. This guide aims to help users maximize their cards that were wrongly limited by fake power settings. Many of these chips are built for higher wattage and can handle 400W+. Cards found on forums often support crossflashing with increased limits. Feel free to share your sources in the comments.
Examples:
- Zotac 3070 Twin Edge OC (240W) flashed to ASUS BIOS (270W)
- Evga 3070 XC3 Black (270W) with FTW3 BIOS (300W)
- Gigabyte 3070 Gaming OC (non-pro) (270W) using Strix (350W)
- Gigabyte 3070 Gaming OC flashed with FTW3 (300W)
- Aorus Master (AUROs) flashed to RTX 3070
- Overclocking tips for 3070 Ventus X3 (220W)
Note: Some cards are restricted by power connectors, especially those using 8+6 pin designs.
I'm experiencing issues reaching voltage beyond around 1.068v. Can you adjust the voltage settings for me?
Well, it comes down to a few factors. My 3060ti has power restrictions because the Gigabyte unit is fixed at 100%, which limits how much the fan can spin. With my OC settings, I can't push the fan above 86% without risking excessive power draw that could hit performance limits in benchmarks. This matters more for testing than for gaming, though it does impact my score results.
you're checking MSI Afterburner? make sure you've verified your BIOS settings for the power limit in watts using TechPowerUp's VBIO database. if you can't locate it, consider searching for unconfirmed BIOS entries.
after using MSI Afterburner, verify these settings are active. To force the card to operate at your desired voltage, use the graph curve and confirm the BIOS is being commanded correctly. If MSI Afterburner doesn’t display the voltage despite other tools showing it, check with hwmonitor or hwinfo—especially since with my EVGA RTX 2060 KO other software works while MSI shows nothing.
Yeah those are enabled. Also can you please direct me to a working nvflash? The ones I found cant override GPU mismatch errors?
did you run the protect off command? i know from what i studied the card list isn't always trustworthy when determining real power limits. this is the right page, and it should show what appears after u upload to the database with GPUz. there are at least two versions: one with a 220watt bios and another with 200watts.
