hello guys, I need to help on a gtx1050ti, the card does not have Vgpu voltage, follow the information in the images, I would like to know what is the red circle ci, because I believe it is the reason for the failure, there is no voltage present in none of your pins.

Can you read the marking on red circle IC? On photo it is unreadable. Also which IC pins are 0OHm-to-ground? The only IC that I saw on GPUs in TSOT23-8 without a choke/coil near is up1801 - "programmable high-precision reference voltage". Вложение: UP1801-reference-voltage.zip Its top marking is N21. It was near PWM controller, but the card was another: high-power AMD 290/390. There is a lot of TSOT23-8 voltage converters, but thaey are always near choke/coil
Is there a small choke/coil on the other side of the board near that ic? |

Hi, Team, I will add one more question regarding same ASUS GTX1050Ti board. I have dead VRAM voltage FBVDDQ formation chip. Its marking its "6X=4E A2B" Its 10 pin chip possibly ground pin under it. I did not able to find it on google, aliexpress/ebay or China manufactures chip markings database. Can anybody recognize this chip. I did found on MSI 1050TI schematic similar chip uP1537 but pinout is not as per Asus PCB. Thanks in advance. |
