Hi to all!

I have a p104-100 (flashed with 8gb bios) not working, on windows i see ti like a video accelerator and when i try to install the drivers i gave a blue screen, if i install it on safe boot mode i give a ble screen at the restrart...
On hiveos it detect it like gp104, but when miner start it say no gpu selcted or supported and goes to loop...

All the voltages present on the pbc, im trying to run mats, but gputest say erro:heatstresstest is not defined, an if i try to run mats -n i give an error say adatper not found with index 1 or similar....

Any help its appreciated !!!

Bios is not fetched by the GPU and by extension by the motherboard. Please check pin 1 of the bios whether you have pulses on the /CS pin. I have such cards which stopped communicating with the bios chip and I can't find a solution. All voltages are in place but bios signals are silent.

Для теста mats - ввести команду -3d_card

1: карту первой
2: монитор в мать, если есть встройка
3: матс400, запуск, до командной строки
4: "./mods gputest.js -skip_rm_state_init -oqa"
5: Enter
6: "./mats -3d_card -e 20"
7: Enter

это с форума инструкция

mods не запустится так как модифицированный биос под 8 гигабайт а стоковый биос - под 4 гигабайта Можно зашить биос стоковой прошивкой и проверить mods

first step - reballing memory, control of date and address lines, Maybe
replacement memory .
second step - video chip - reballing

Then it could be a vram issue?
