Now you got me thinking if a resistor was blown on a parallel I coudnt pick it up individually , I have to remove and test individually ? Start measuring amps and voltage drops ?

I will look into an Aoyue thank you. The reason I am assuming the Bios chip is strictly because of what I read on the wiki page. I'm not thinking its its a cap, pcb, or gpu die because I can not find any sign of physical damage from temps or anything melted, When I try and follow the...

I've never diagnosed a gpu or attempted a repair on one before. I dont even have a rework station yet. any suggestions ? all the reviews say they blow up and catch everything on fire.

Thank you so much for your response. I feel I know just enough to be dangerous Because of my low resistance. yes i think there is a problem on my 1.8v rail. The Pascal wiki points me towards the Bios chip for a lucky cause of low resistance. and its a easier chip to pull than the 1v PEX rail...

Found this for a diagram here : https://repair.wiki/w/PEX_Rail_on_Pascal_GPUs.

if i power up the test bench and sit in the Bios would that be less risky for my GPU without a cooler ? or would it be under just as much stress as sitting on windows desktop ?

Please dont laugh, but I rigged up a test bench to power this. I found all voltage present but the 1v PEX Rail. also during this as you can see. while seating it in the x16 slot , capacitor C163 fell off. I think board flex ? shows markings of : 330 2R0 H36 I think its a 2V 330uf tantilum...

My 1.8v Rail resistance looks low to me. im going to go poke around again, also see if I can find any more information. what is strange is all the resistors on the 1.8v line I measured on the bad card at 342 ohms. all measure 896 on this card. the C264 , C266 , C270 , C272 resistors and the...

Here are the results from a proven good EVGA 1080 FTW ( Rev 1.1 / Chip 1639A1 ) ------------------------------------------------------------------------------------------------------------------- Pcie : Pcie 12v pins : 52.30k ohms pcie 3.3v pins : 25.83k ohms...

Alrighty ! Today I thought about what I should do next. those readings arent terrible , but after the hard drive wipe, and riser cable incident im nervous about plugging this card into my systems. I decided to set up a test bench. to power this card I will need to switch out the mining rig...

Alright. so ive been working away gathering everything to start again. With the negative probe attached to ground through my DVI housing I measured resistance at the following : 12v Rail : I noticed the resistance started at 1k ohms, would rise pretty fast to about 6k ohms, then jump to 30k...

Im going to start over since I got no where.

Thank you for reaching out to me. Ok so early this morning after looking over my findings and checking between pins at the U3 bios chip. I found that pins : 3,7,8 had a resistance of 0.0 ohms. after checking this chart that makes sence since they all connect to the 1V8 AON line, I didnt find a...

after thinking about this for a little bit. I think if I could verify those readings against a known good card and the numbers are the same it would mean the 1.8v circuit is ok, and the problem is in this chip.
