This necromancy is super impressive. GPUs are some of the most complicated devices inside modern PCs, basically minicomputers themselves. Love this and the motherboard/gpu breakdowns the best.
BIOS chip failures are common for old hardware. I've had two identical MB fail in different ways two years apart. They were from 2012 IIRC and one is still in service. Flash looses data over time if it is not refreshed and these chips typically don't do it. One board would apparently not do proper training of DRAM, which would result in strange incompatibilities. All those were fixed after a flash and the board is fine. The other was your regular black screen. Also bought an AM3 board from ebay, sold as good, which didn't boot. After a while BIOS posted requesting I help it recover... I put a file on USB and the board has been used for two years after that with no issue.
I had a failing mosfet literally melting solder to one of those 330nH memory inductors. And, like, 2 sec after power up, not like after 15 min of kombusting. I didn't think of using through hole inductors that would use an alu cap as a heatsink lol :D Btw, same card, 980ti from inno3d, awesome three fan design. I wonder if we could get away with simply bridging the tabs, should we run out of inductors I mean, 330nH, that's like wire wound up 3 times around a pencil.
Still on my trusty old EVGA 980ti ref card. Unfortunately, both the DVI and Display ports have packed up, so HDMI only now. Time for a new card I think!
G'day Buildzoid, I love your repair videos especially when you make them your own with quirky fixes like the VMEM Inductor V-Twin pattern you did here, 🤔maybe you could add some BZ/AHOC Graphics & sell some of the multiples you have fixed "AS IS" even without a cooler. I'd love a BZ Sculpture on my PC desk. I bought a Power Color PCS+ HD7770 from England, I did my best to make so it could acclimatise to being down here in Australia by turning my Testbench upside down but while listed as working 😢sadly it doesn't (with H55 Test Bench Fan spins + Single Post Beep, but Black Screen). I took the Cooler off & it has blown a Q801 chip next to the 2R2 Choke (Bottom Right when held with PCIe to bottom), I did get a full refund from the seller with no trouble but would really like to get it working for a C2D E7500 XP PC I have. I haven't repaired a GPU before but have done lots of soldering over the years as the GPU was basicaly free do you think this would be a good first GPU project? also I have some random dead GPUs like a 650 to practice Desolder/Solder plus some other Dead GPUs like 4x Sapphire RX480 + 2x HD7970, GTX460SOC too with plans to work out what is wrong with them & maybe get 1 or 2 working.
BZ you do know that those BIOS chip flashers are only about £12? Well that was the price I paid when I managed to fix one of Gigabyte's infamous 'dual BIOS' motherboards. I mean I hear what you're saying, but chances are at some point, you will buy a dead GPU where someone HAS done something dumb with the BIOS . . .
I have had a 1060 get a bad bios chip, one of the bytes would always fail and wouldn't zero out when I tried to blank it, it got memory errors on all chips and I thought it was a write off
Not really. MATS is for all nVidia cards, I don't remember what is used for AMD cards and I don't think anybody has made anything for Intel yet. But you wouldn't use these tools through Windows, you would boot into them.
I have a gpu thats goes black after installing a driver in windows, thank you for try this video I will try this. Any tips for locating these resisors? The only idea I have is to search the right pin in the datasheet of the uC and then search for the resistor with 0 ohm connection to it. Is it a good idea?
Ok, thank you for response, btw from what I remember I tried multiple bioses (also the "original" one), so maybe it's not the bios fault (however I might have a different issue) @@ActuallyHardcoreOverclocking
Huh, you actually mentioned the driver, I think I also tried multiple drivers, but not sure. Maybe Windows power plans are also in the play, but I think I will stick to the solution with the highest amount of heat
17:20 Usually the point of doing these things in software is that it's supposed to be easier than tricking the power monitoring chip or whatever other hardware wizardry ur doing haha
@@coccoborg yeah documentation is the most important part of PCB troubleshooting, i fixed a 1070 in the past and without schematics its not worth the time
once again forbidden arts of GPU necromancy with buildzoid !
BZ single handedly saving old GPUs from the scrap bin one SMD at a time.

I want to say that I truly have NO idea what you're talking about 90% of the time but you're really pleasant to listen to.

23:23 - BZ having a chuckle is the same energy as IT Crowd's Maurice Moss laughing at a circuit board.
Time for bullzoid to go into GPU reballing !
And here I am, proud of myself for repasting my gpu for the first time last week lol
Watching this via my EVGA 980 Ti on my old gaming rig.
I was literally just thinking i haven't seen you in years and here you pop up on my feed. CZcams algo be reading minds now.
hit that bell babe

preheat-er would solve your problems , with hi temp , I solder mem chips with 180 - 200 C and board preheated to 180C
Despite being a decent modern card the 980Ti and 900 series of GPUs are on the chopping block to have their support dropped in the mid to near future.
Interesting fix! Always learning.....

Will we ever see extreme OC from some of the budget gpus you have
H e y BZ, at least you had fun fiddling with the card!🎉😅😊
don't you have any back heating?
I have had a GTX 970 that i was able to repair by replacing the BIOS chip, I'm pretty sure those do die at times.
My 980ti kpe started to throw artifacts after nvidia update on the benchmarks lol. Before updating it ran fine

I still have waterblock for 980ti\titan x with a black plate. I had 2 but sold one, just say if you need it.

transfer the core to strix pcb, that will be a good one
isnt a power stage failure (12v to core short) guaranteed dead core?
GPU cores tend to survive Vcore VRM failures. The memory controller and memory chips on the other hand don't tend to survive Vmem failures.
Hey, do pro GPU repair.. should help you with the channel + earnings. And you can keep on doing what you love to do.
Is there a universal tool on Windows testing vram? Like TM5 but for gpus.
Not really. MATS is for all nVidia cards, I don't remember what is used for AMD cards and I don't think anybody has made anything for Intel yet. But you wouldn't use these tools through Windows, you would boot into them.

that's pretty much how I found these resistors. From finding the pins in the NCP81172 datasheet.

At least is a ref pcb
I'm not really aware of any 980Tis with a PCB worse than the reference PCB.
