Flashing the on-board Thunderbolt firmware must be done with care and patience.Hi, I have a fully working Z390 Designare. But I need to flash the thunderbolt firmware due to blackmagic Ultrastudio issues. (It lags by 7 seconds after several minutes of playback all of a sudden, even though everything is word clocked.) Unfortunately, I can't buy another Designare MB since they are not available. I have bought the tools to flash. But I am not comfortable in blowing it up since I can't purchase another MB. Is it really that difficult? Has anyone burnt his MB doing this? Is there a similar board that could replace this one in case I mess up? Thanks for your help
- If you rush, you will fail.
- You must have EXCELLENT nearsightedness. If you are naturally nearsighted, you should remove contact lenses or glasses (which provide far-sight focus).
- You must have STEADY hands. There are tiny surface mount resistors close to the Thunderbolt firmware chip on the back side of the motherboard. A number of folks have accidentally dislodged these components while attaching or detaching the SOIC clip.
- If one of these resistors comes out, Thunderbolt will permanently fail. Attempts to replace the resistor may or may not work.
- The SOIC clip must be attached and detached GENTLY.
- You must work in GOOD LIGHTING conditions.
- Use the 3.3V Arcelli or equivalent device for best results. Refer to Quick Reference spoiler (section 8) for mini-guide on using the Arcelli.
Each person must determine for themselves whether they are confident in the procedure and in their hand-eye coordination abilities. They must also determine for themselves whether they are comfortable with the risks involved. Anyone who feels "clumsy" (I don't use this word in a derogatory way) with delicate tasks should avoid this.
Alternative option is to purchase a Thunderbolt add-in-card such as GC-Titan Ridge and flash the firmware of that card. A flashed PCIe add-in-card will not be as reliable. It will require starting the computer and doing one reboot every time. But if the add-in-card is damaged, it is more easily replaceable.
