    NVidia bumpgate
    by piernov
    Just archiving everything related to bumpgate since most stuff has disappeared from Google. Maybe people will finally take the time to read some of it and stop shouting "reflow gpu" at every occasion but rather try to understand what the real issue is…
    Interesting parts about the failure analysis are "Why Nvidia's chips are defective" and "Why Nvidia's duff chips are due to shoddy engineering"


    May complete this post at a later date with more details.
    Basically issue is a combination of thermal dissipation of the chip with hotspot,...

    Dell Inspiron 7501 / Vostro 7500 (2020) - eDP connector pinout/panel compatibility question
    by pickledegg
    Hello. I have an Inspiron 7501 here, it's the same as a Vostro 7500 in some markets (no clue). I was looking to replace the LCD, the panels included with these models are terrible.

    I have the schematic and it is a 4 lane eDP port on the board but the pinout seems quite weird, my question is if anyone recognises this weird pinout and knows of any other Dell models that may use it or even any compatible panel models.

    How do I find a defective RAM chip

    Korg Kross2 Service Manual and LCD pinout
    by maleksa
    The LCD on my Korg KROSS2 keyboard is cracked and needs to be replaced.

    However, the cost of a replacement LCD is almost the same as the price of a second hand Korg KROSS!

    Does anyone have a copy of Korg KROSS2 Service Manual? I want to see the PINOUT for the LCD connection. Perhaps I can find a compatible LCD screen and not have to spend a fortune on an original replacement LCD.

    From what I can gather, the LCD screen is a COG with serial interface (SPI). Is there any way I can ascertain (perhaps with the use of a multimeter or oscilloscope) the PINOUT by...
