Seeking Boardview for MSI 3060 Ti Ventus 2X OC
Hello everyone,
I’m currently working on a repair for an MSI 3060 Ti Ventus 2X OC graphics card (Model #: MS-V390 Rev 1) that experienced a Vcore short to ground. This issue has resulted in a low resistance reading of 2.6 ohms on the 5V rail. After identifying and replacing the faulty MOSFET on the Vcore VRM, I found that while there are no longer any shorts present, I am still not receiving Vcore or Vmem output.
To troubleshoot further, I have traced the problem back to the Vcore FET driver. My current approach involves utilizing a 3070 schematic, which seems to feature similar components. However, navigating the repair without a dedicated boardview is proving to be quite challenging.
I would greatly appreciate any assistance or guidance that anyone in this community can provide. If you happen to have access to the boardview for this model or can point me in the right direction, it would be tremendously helpful.
For reference, here are some resistance measurements I’ve gathered:
– Vcore: ~1.3 ohms
– Vmem: ~15.3 ohms
– Pex: ~7.6 ohms
– 1.8V: 0.971 kΩ
– 5V: 1.085 kΩ
– 3.3V SEQ: 16 kΩ
– 12V PCIe slot: ~18 kΩ
– 3.3V PCIe slot: ~100 kΩ
– 12V PCIe cable: ~18 kΩ
Thank you for any help you can offer!

Hi,
Thank you for sharing detailed information about your repair process. Access to a boardview can significantly simplify troubleshooting by providing a clear layout of components and circuitry, especially for complex VRMs and driver circuits.
Since you’re working on an MSI 3060 Ti Ventus 2X OC and currently do not have a dedicated boardview, I recommend the following options:
As a last note, always ensure you’re working with the latest, verified schematics or boardview files to avoid
