I Really like the PCB breakdowns on your channel! You do a good job at going in depth, explaining things, while still being easy to follow. 10/10
why 360p quality o mighty buildzoid, WHYYYYYY?
I have a cracked L14 in a Tesla M40 card (very similar PCB). Any idea on what is that and what could be have caused that? It burned my motherboard VRM. Looking forward to maybe repair the Tesla. It also have DrMos 4 from bottom to top missing unlike this card. Card was detected properly by driver setup program but after a while burned my motherboard VRM. 12v PCIEx in the socket reads 3.9 ohm to ground. So seems something is shorted.
Hello friend, I have an evga GTX980ti that is missing several components, could you send me the photo you are seeing? from the top. Thanks for your help
Care to help a fellow novice guy like me? I have the exact card which was recently given, dead on arrival! The owner said it has the classic symptoms of not turning on, my guess something is shorted out. Visual inspection doesn't reveal much on the pcb, looks clean. Do you have the pin out for the PCI express slot,? looking for 12v lane. Any tips on trying to diagnose dead mosfets on this particular card? Is there a difference with SiC -789 AF T542 mosfets? This is what I have instead of 6823A Thanks, Cheers.!
hello, where's the bios chip on this titan x pcb?
And the Tesla M40. Ought to add that to the title lol
sorry but CC is on and sound is muted. and you know why !
If you could find the time, to even do a VERY brief overview of the G1 Gaming GTX 980 Ti I would be eternally grateful, kind sir BuildZoid!
I have never hard-modded any GPU before, but there are some things I would REALLY like to try, also - I am that kind of insane that where I start wondering about something, I CANNOT stop until I find my answers..
I am on my Tablet right now, but if you want some high quality 1080p pictures BitTech.net has them all, IF you require something more detailed? Well I would gladly yank my card and snap some higher quality pics - what does the Note 5 have, 12 MP IIRC.
980 ti xtreme .... explaning the ln2 would be great
You should start doing MXM cards. I guarantee there would be a lot of views for that. A notebook forums would be here in a second. First card would be the MXM 3.0b that has the notch on it MSI 1070 model is MS-1W0V1
Send me more messages about this
Hello, first of all thank you for the in-depth analysis of all the pcb's out there, amazing job!
Now my question is, i have a founders 980ti with apparently a broken vram voltage controller (havent measured yet) am i able to shunt over it? So would the shunt bypass the controller to feed the vrams the required voltage? My 980ti runs and core warms up so core voltage is not an issue, the card is not displaying any image. Any advice on measuring the controller chip?
Awesome video! Please do a reference/XFX 390X/290X
+Jose Adorno 290X reference is on my to do list. The 390X is only a little different but I'm not sure if I'll do a video about it.
Please make a video about the 390x reference; even if it's a little bit different, we'd like to see what are those differences :x
Regarding the current sensing pin; If you have fine enough tips and tools, and steady hand, could desoldering it from the board pad be an option? - Then cut a sharp/narrow wedge of kapton tape, lift the pin so it does not press against the PCB (without plastic bending it), and jam that capton tape wedge in between the leg and the pad...
What happens when one of the R33 inductors is missing? I had a card that works but crashes when pushed. I replaced the R33 and it looks like it works better. Less likely to crash.
My R33 blows up. Where can i buy a new one?
ĐΔNĐELĬƟN Thanks
thanks, this is the reason I put up my post. was what I needed to find.
Toan Ho Mine was missing one aswell? And my card is crashing pretty often. I have a broken gtx 780 so i’m taking off one of the r33 inductors and replacing it, wish me luck haha.
not luck. near half have r33 blown.
My EVGA 980ti just went up in smoke while gaming - literally. One of the the memory VRM inductors fried (lower R33) the R33 above it looks golden over heated and 1R0 got so hot it melted the solder and started to slide down the PCB and is on an angle. The shunt resistor just below the fan header is also bubbled and crispy. _Question:_ what happens when the inductors fry? Is there a chance my card is salvageable if I replace these components or is it likely other components are now fried too?
Honestly that sounds like you might have to replace the entire VRM. There's too many parts that failed.
Thanks for the prompt reply. If I had a "parts card" laying around I could pillage I would give it a go but it doesn't seem worth sourcing one at this point on a long shot. I got a _really_ good deal on it when I bought this card from a friend who just sold his last 980 out of his old 4x 980ti SLI rig which I now own and I'm bummed I have to spend over $500 on a new card to match its performance. And yes, 4x SLI is nothing but trouble :P
A Fury X/nano PCB breakdown happening or?
Eventually
What you think about the 980ti Classified PCB? I guess what I mean is did EVGA use good components?
Did you ever look at an EVGA 980 FTW? There was some speculation that their non-reference VRM design didn't quite work well, because relatively lot of the owners had stability issues.
nope and I'm pretty sure it's a reference PCB
The smaller 980's other are reference PCB, the FTW is not. Somewhat similar, but in the end, not:
forums.evga.com/FindPost/2292536
More inductors, for sure, others stuff I can't make out.
Nevermind, thanks for replying, though.
what is IC number in Green cross CHIP(Memory voltage CT)?
What is a crystal oscillator? My 780 ti has a problem, it gives image while using Windows for youtube or Netflix with a stutter from time to time but the real issue is in games and sometimes it just opens the menus from certain games but I can't ever manage to run any game or benchmark and when it fails it freezes the whole computer please I would really appreciate if anyone could give some info on what could be the problem and with who I should try to get it fix
Hi i need some help, I got titan x and fan don't spin at all. I think it must be the fan so I buy a new one but the new one also doesn't spin any idea what component clued be dead ,or a where I have to search on board.
My GTX TITAN recently died. I have checked the pcb and measured the power rails, gpu chip vram etc and they were fine, except the inductor that is next to the buck converter (down on the right side of the pcb. I normally should get around 2k ohm but i get straight 0. I removed the ic chip and i still have the same resistance. Do you know what other components are connected to that rail. Or what component can cause this?
can you explain how the voltage controller generates a pwm signal and what happens then ... mosfets gets the pwm and send voltage to the coils ? where are the inputs and where the outputs this wuld be very helpful to analyse defective cards and repair them .... actual i got a 980 ti with no voltage at the coils output for gpu core and memory :(
Greetings
I have recently acquired Gigabyte version of this card as non workable. It shows the picture, but when on load sometimes it gives BSOD. Also the LED was stuck at green all the time. I was able to fix the LED, it was faulty cable. After testing numerous drivers and software fixes i finally was certain that it is a hardware issue. After removal of the heat sink and and close inspection of PCB board i noticed that one resistor seems to be knocked of the board. I am familiar with electronic repair and i have hot air rework station so to replace this resistor shouldn't be big of an issue.
i have found online the picture of the PCB for this card and confirmed that resistor is on the board normally. It is also here on this PCB from Nvidia, that whole section is the same. It is resistor R77 on Gigabyte version and it is located just below the GPU. in between GPU and PCI contacts. Look at this image: www.dropbox.com/s/w1l1k5o7f6qjqez/R77%20Location.jpg?dl=0
This is the closeup of that area where the resistor is knocked off: www.dropbox.com/s/fq4vmbkxvnyoaux/IMG_20190216_173300.jpg?dl=0
I have measured the nearby resistors to be R78 and R79 around 36 ohm and R76 is 2.2K ohm.
So my question would be, if you still have this PCB form this video, can you measure this R77 equivalent resistor?
Thanks.
I've been struggling with a Titan X maxwell overclock (Tesla M40 actually) I can get the core to 1500Mhz, and the memory to 8000Mhz, but if I go above 1400ish on the core (with higher voltage) the memory can't even get over 6000mhz. I have the power limit raised to 300w, and the card is generally only pulling 250. Core is water-cooled, temps around 48 C. If anybody has any ideas I'd really appreciate it!
I have the eVGA 780ti SC model which doesnt accept bios hacks. If I short those shunts you showed in this video will that allow me to bypass the Volt limit?
awesome again. thanks
Doesn't many SMD components like resistors, diodes etc - especially large ones (like shunts here) - have end/contact caps made of aluminium and tin? ^^
Can you tell me what the component located at U16 is (mid right side)
Late to the game, TLDR, does populating the 3rd 8-pin do anything on the reference 980 TI? I unfortunately have the PNY blower 980 TI, which has the lowest set power limit in its BIOS, looking to flash that at some point cause I finally got a water block for it
I have a question about this PCB. My EVGA 980TI has blown itself up last night while gaming. I haven't overclocked it and it has descent cooling from the original heatsink and fans. Now that I opened it up, I saw the damage that happened. Now I'm scared that it could have damaged other parts in my PC like the PCI E port or my monitor that was connected with the DP output. Can you tell me by taking a look at some pictures of the burned out parts that collateral damage to the mobo is in fact a likely scenario? I can't test it with another gpu because I don't own a spare one.
what parts burned ?
I have gtx 980 ti and it restarts my pc under heavy load (intensive games works for around 5-10 min), is not psu or mobo , tested in another pc .
Is VRM broke ?
can i attach a temperature probe for my loop to the 2 prong header?
6820a
Can i use Asus Strix GTX 1080 ti heatsink on msi gtx 980 ti reference?
What is the component L14? and how it works? to me it burned.
does Overvoltage make ANY sense at all with maxwell and aircooling? On a GTX 980?
970's pcp breakdowns nowhere :( hope this will do.
Can u give me Evga Gtx Titan memory voltage control Driver ic number
the first or second from the top "core votage' things that you highlights caught fire on my 980 ti... is there a way to fix it... it won't turn on and i bet if it does it'll probably just caught fire again.
It probably is repairable but it's going to be really hard to do.
Lets say one of the mosfets on a 980ti got removed. Would it still function with the other 7?
Back from the dead lol
Yes, it works for low power (
A little late to the party, but does anyone know how much power the "GEFORCE GTX" lighting strip requires? Would like to repurpose it from Titan X cooler. Thanks, great videos man :+1:
Do you know where I could get the electrical schematics?
For the PCB? Probably impossible unless you know an engineer at ASUS or some other big GPU maker.
I was afraid of that. I have a "friend" not a friend, he posted in a forum for help, and I always try to help. he his board pissed on by his cat. he said it won't even start. I'm trying to walk him through the repair process online since he doesn't live near me or I could do it. That is where my microscope helps for this stuff, makes soldering those tiny pins a cakewalk. But I digress. I told him to probe the mosfets. for voltage input, and the pwm signal on the gate. I think the issue is in the pwm circuitry. but idk yet because he hasn't gotten back with me yet. but it will just be a pain in the ass without the schematic. it can be done but it isn't fun without a schematic.. I offered him my gpu repair services if he doesn't want to repair it. have a board to measure for reference, microscope and oscilloscope, and smd rework tools. will make this easier for me. I'll dig a little more the the schematics, I know there out there somewhere but as you said, probably impossible to find
Thanks for the reply, man.
Thanks a lot. Very helpful. One more question how much volts do you recommend for 24/7 usage on air?
(Im currently running 1.274v 1500core and 7980mem)
+xXsch3ricXx temps don't go higher then 71 C at the moment. (so would it shorten the lifespan a lot if i go higher?)
+xXsch3ricXx 1.3V should be safe however based on what I've read there is a good chance you won't see an increase in OC headroom.
+Actually Hardcore Overclocking Ok thank you.
1500 on air! Wow.
Hey man, I'd really appreciate if you could help me with my problem: I have a "GTX 970 Zotac AMP! Omega", the one with orange stripes and 2x8 pins and I have a few problems with it. By the way, I wanna watercool it. 1 Problem) My card clocks itself down for no significant reason other than being above 180 Watts, even though it has somwhere of 250 watts just by the 2x8pins. 2 Problem ) In my Stock Boost Table theres some Clocks where there is 1.28 Volts on the core, but my measuring points measure only 1.24 max, is there any way to fix both of these issues?
Really would appreciate it! (Theres high-res pcb pics on the internet)
The voltage going from 1.28V to 1.24V is probably just vdroop and you need to either get LLC settings(not possible AFAIK) or just raise the core voltage to compensate for the drop to 1.32V(doable with a custom BIOS or hard mod). As for the power limit you could go with a modded BIOS or just short out the shunt resistors on the card(from the 1 pic I've seen there is 1 shunt right after each 8 pin connector). BTW I haven't touched a single 9XX Nvidia card so I'm no expert on them and I'm just going of things that I know generally work.
well my problem is, that even if i put everything i need to volmod the card to 1.337 volt (see what i did there?) my multimeter still only says 1240mV
Any suggestions?
You're using software voltage control?
No in the voltage table of the .rom i edited every necessary voltage to 1.337 volts and I patche the bios rom with nvflash
And that's outside my capabilities on Nvidia cards. A physical volt mod would almost certainly work but I'm guessing you don't want to do that.
things get crazy when you take a look at what gigabyte did with their board design - cdn.overclock.net/0/03/03fa3cec_front_full.jpeg - i love this card i got, shame i don't do anything fun with it besides a general overclock of 1520/2000 @ 1.268v with gpuboost disabled
Can you do a short video on high bclk overclocking. like very high 5+ and how can I achieve that on a 5 phase vrm? design
+Mohammad Ali why? what mobo do you have?
+Actually Hardcore Overclocking gigabyte z170-HD3P with a i5-6500
+Mohammad Ali unfortunately I don't have any skylake stuff on hand. However from what I've read you need a non-K overclocking enabled BIOS. Do you have one of those?
+mr.cleaner yes. I am running my processor right now 4 ghz
+Mohammad Ali Unfortunately I can't help you with that since I haven't used skylake at all. The only thing I can think of that could be limiting you is that you aren't underclocking your RAM but I guess you already know about that.
