I have 3 EVGA 2080 tis, and all 3 of them have memory errors on the first 8 bits of B0 (B000 - B007). Ive replaced the mem chip on 2 of them but they both still fail on the first 8 bits. Do I need to reflow the GPU?, or is there some cap that controls this? |

I'm not sure how the chip works on 20 series card, but on 10 series cards, the first bits of memory are the internal memory cache of the GPU, I heard that you should not pay much attention to errors in the first bits. You need to check mats at least 400MB or more |

Do i need to just check the data lines on the PCB in diode mode to ground? Posted after 2 hours 44 minutes 7 seconds: I just checked all the lines on the bad chip and under a good chip, they all look inspec with around 0.27 V. |

Can you please share your MATS report? |
