I was thinking that GPU crystal wake up the last. So i should check voltage to crystal? Yeah 38ohms is vram...

Zotac gtx 1060 3gb missing one rail
Hello everyone, i have zotac gtx 1060 3gb, and it has missing one rail. I think its 1v but I'm not sure. This rail has 34 Ohms, but after test on on my testbench, it drops to 2ohm, after some time it back to 34 Ohms. Next to this coil is up1727q. And there are 3,3 on vin pin and 5v on vdd pin. I changed this chip with another one but it didnt help. When i tried Short circuit test, core didnt heat up so maybe its still alive. I dont have thermal camera :/. I dont have boardview and schemstic for this GPU too. What should i check next? Or maybe its just dead core?1 Photo

Re: Msi R7 370 4gb not detected
You right. Here is photo with fan connector. There is weird voltage on gate i mean 2.8v, i changed capacitos under this gate, and voltage calm down, but 2.8v still exist.

On second video was 11.80v, card was warmer, so maybe it was the reason for lower voltage than these picture.
When i get this card from my friend was like that (i speak here in polish). Fans restarting like voltages rails

Re: Msi R7 370 4gb not detected
On The coil 12v, 3.3v and 12v lines from pcie arent shorted. Volts are in. Restistance on 12v in ~100K Ohms, on the 3.3v line 2.6k Ohms. I
think this card has problem with initialization now, because all lines are working(i think). I dont know how to check communications between bios, core and motherboard. Crystal is getting warm when card is power on, thats why i use small cooler on it to measure voltages when working. I dont have osciloscope to check signals lines. Thanks for advice!Last edited by Grucha98; 11-15-2021, 03:46 PM.
