Introduction: The Rare and Powerful RTX 3090 Kingpin

The RTX 3090 Kingpin is a highly sought-after graphics card known for its liquid nitrogen overclocking capabilities used by top overclockers in the industry. In this article, we will delve into the repair process of an RTX 3090 Kingpin that suffered from a dead power stage. We will guide you through the step-by-step process of diagnosing and fixing the issue, showcasing the techniques used to ensure a successful repair. So, let's get started!

Checking for Short on the Base Voltage Rails Before diving into diagnosing the issue, it is essential to check for any short circuits on the base voltage rails. By using a multimeter in continuity mode and probing the components connected to the ground, we can detect any shorts that might be present. In this case, the 12 volts and 3.3 volts of the PCI Express slot were tested and found to be in perfect working condition.

Verifying the Voltage Rails of the PCI Express Slot Next, we want to ensure the stability of the voltage rails of the PCI Express slot. By checking the first three pins at the P64 slot, representing the 12 volts, we confirmed that everything was functioning correctly. Similarly, the 3.3 volts were checked by starting at a specific notch and probing four pins to the left, confirming their proper voltage.

Confirming the Voltage of the External Eight Pin To complete the initial checks, it is crucial to verify the voltage of the external eight pins. This graphics card has three external eight pins, and each one was tested individually. The top, middle, and bottom pins were all found to be perfectly fine, indicating no issues with the power supply.

Testing the Voltage Rails Generated by the Card Itself Moving on, we wanted to examine the voltage rails generated by the graphics card itself. Using resistance mode, we began by checking the 5 volts to circuit 5 volts. There are two 5 volt rails in this particular card, and both were found to be within the expected range. Additionally, the 1.8 volts and the PEX rail were tested, providing satisfactory results.

Identifying a Shorted Memory Phase During the diagnostic process, it was discovered that one of the memory phases had a short. This is typically a fatal issue that can result in permanent damage to both the core and memory. However, in this case, it was likely caused by the previous use of liquid nitrogen overclocking, which made the repair possible.

Replacing the Dead Power Stage To remedy the shorted memory phase, the dead power stage responsible for the issue had to be replaced. By utilizing a thermal camera, the short was identified, allowing for a precise replacement. The faulty power stage was changed, addressing the root cause of the short.

Confirming the Functionality of the Replacement Power Stage After replacing the power stage, it is essential to confirm its functionality. This confirmation was achieved by using an oscilloscope to verify the proper wavelength and voltage measurements of a working power stage. The replacement power stage showed identical readings, indicating that it was indeed functional.

Testing the Other Power Stages To ensure the stability of the other power stages, they were also tested and found to be in good condition. This additional step guarantees that there are no hidden issues that could arise later.

The Successful Repair of the RTX 3090 Kingpin With the dead power stage replaced and the functionality of the other power stages confirmed, the repair of the RTX 3090 Kingpin was a success. The graphics card is now fully functional and ready for use. Repairing such high-end and rare graphics cards requires expertise and precision, but with the right tools and techniques, even the most challenging repairs can be accomplished.
