    EVGA GTX 1060 1V Missing (Pascal)

    Okay went through and pulled up several datasheets for chips on the board. As well as double checked resistances on rails and voltages at different points in the card. I'm uploading the photos so you can see everything labeled. I do want to apologize as this is my first GPU I'm attempting to...

    EVGA GTX 1060 1V Missing (Pascal)

    Okay after further learning, reading, and testing. I'm missing vcore voltage. When checking uP9509 (Vcore controller) I'm only getting 0.46v on Vcc. I'm only getting 1.4v on the EN pin for it. This explains why I'm not getting Voltage on Vmem and PEX because of the power sequence the cards...

    EVGA GTX 1060 1V Missing (Pascal)

    I'll have to check tomorrow when I have the card for exact resistance. The datasheet I looked at (https://datasheetspdf.com/pdf/1259305/uPISemiconductor/uP1728/1) Chip Enable/Disable and Soft-Start "The uP1728 features an EN pin for enable/disable control of the output voltage. Pulling the EN...

    EVGA GTX 1060 1V Missing (Pascal)

    I'm not sure why I had informed you the EN pin was showing no resistance to ground. After walking away from the card for a bit I have returned to it and am just going to restate what I know for myself and hopefully as to not give you wrong information again. I'm going to approach this as if it's...

    EVGA GTX 1060 1V Missing (Pascal)

    I don't believe it's a short because my multimeter meter was set to the highest resistance setting of 200M and I actually got a reading. I know when the card is powered on I get 12v on the same measuring point. I also get 12v in numerous other locations that it's expected to be. I do just have...

    EVGA GTX 1060 1V Missing (Pascal)

    Furthermore, I'm not sure if it matters. However, I do not get any voltage to the feedback input pin on uP1728Q. I understand the enable voltage is low but also reading the datasheet that if FB is under 0.26v it will use under-voltage protection to shut off the ic. Do I need the enable signal...

    EVGA GTX 1060 1V Missing (Pascal)

    Attached are some photos of the card with measurements as well as the points they were measured. Being honest I wrote 1.0Ω @ 200M because I know the max resistance is 200million but my brain couldn't process if i was getting a 1 million ohm reading or 100million. To find the converter that...

    EVGA GTX 1060 1V Missing (Pascal)

    I forgot to check resistance to ground before removing the chip. After removing the chip the resistance to ground reads about 1 Ohm.

    EVGA GTX 1060 1V Missing (Pascal)

    After testing with the IC removed, I'm still getting 1.76v to the EN pin. Is finding the fault on this line going to come down to checking with continuity and visual aid? I'm not aware of any schematics available

    EVGA GTX 1060 1V Missing (Pascal)

    Appreciate the input, fortunately have another IC I can use Incase I did fry it. I typically preheat the board before blasting it with hot air. But I'll reply with the voltage on the EN signal after I remove the IC again

    EVGA GTX 1060 1V Missing (Pascal)

    I currently am working on an EVGA 1060. All voltages are present when the card is powered on except I'm missing 1V. The buck converter, uP1728Q is getting power to it. I'm getting VDD- 5V VIn - 3.3v En - 1.76v Mode - 5v Lx - 0v. It appears no power is leaving the controller. What would be...
