Common RTX 3070/3070 Ti Problems
1. Overheating
Causes: poor contact between the crystal and the radiator, low-quality thermal paste or thermal pads.
Especially susceptible: budget versions from Palit, Zotac Twin Edge, Gigabyte Eagle - they often have simplified cooling systems.
2. Cracks in the solder joints
Sometimes found in MSI Ventus and Gigabyte Gaming OC - especially with frequent thermal shocks (sharp heating and cooling).
3. Memory failure (GDDR6 / GDDR6X)
RTX 3070 Ti often suffers from overheating of GDDR6X memory, especially on boards with poor cooling of the rear part.
Symptoms: artifacts, blue screens, crashes in games.
4. VRM (power modules) malfunctions
Often occur due to poor circuit design or overheating. The problem is more common in versions with reduced power supply from Inno3D, PNY, Zotac.
5. Black screen or no signal
Can be caused by defects in the GPU or memory power supply circuits, BIOS problems, or board damage.
ASUS Dual, Gigabyte Vision versions had rare cases of similar problems when exiting sleep mode.
❗ Manufacturers with problems more often:
- Manufacturer Comment
- Zotac Often saves on cooling, especially in Twin Edge.
- Gigabyte Eagle Budget versions with simple cooling and weak VRM.
- Inno3D Cases of soldering defects and overheating have been noted.
- Palit Simple assembly and frequent complaints about fan noise and hot memory.
✅ Relatively reliable versions:
- ASUS ROG Strix
- MSI Gaming X Trio
- EVGA FTW3 Ultra
- Gigabyte AORUS Master
How to avoid problems:
- Buy video cards with good cooling (three-fan, with copper radiators).
- Check the warranty and reviews before buying.
- Use a high-quality PSU and ensure good ventilation in the case.
- Avoid overclocking on models with budget circuitry.
