The thing that I've learned from this video is: "We don't do band-aids here". 👍

The cat playing the piano had me laughing. Thanks for all the great videos

Thank you for going more in-depth. I have been watching a few different repair channels, you are on another level. I feel super welcomed in your videos, Like im sitting there with you. You have taught me all kinds of things. Your ingenuity is amazing. Thanks

I subbed a few weeks ago to learn more about gfx repairs, and stayed for the commedic value xD I love how he makes it look so easy while having fun in the process.

I appreciate your humor in these video's. Not only do I get to learn something, you make it enjoyable too. Keep up the great work.

Great video. The temps have been fine on my Suprim 3090 Ti but i started undervolting. Great to see much less power being used and only lose a few fps.

I enjoy watching you fixing. thanks for sharing. 👍

you are amazing!!! i saw your videos all this week end and a love how you find solutions for strange issues. cool

I had issues like these with an RX590 after a bad maintenance during the time when I was experimenting with different dissipation mods. The way to fix it in my case was to simply do a proper maintenance. Consider that lowering the voltage also lowers the temperature output, and therefore the difference between edges and hotspot decreases. When the difference is higher, you get thermal stress on the material of the chip itself, causing the artifacts. So evening out the spread of good quality thermal paste could also solve the issue without the need to replace the core.

Lov'n the cat on the piano. Great sense of humor combined with Pro Repair. 👍

Thank you for the video and the good information that comes with it!

this channel deserves more subs.

hi, i'm a recent viewer. i really love your videos, they are very explanatory. I'm not a gpu fixer but I specialize in consoles and find many useful tips that can also be applied in my field. I would like to ask you a question. I've recently been perfecting my skills in reballing processors and bought the right hot air nozzles for this job, so my question is this: what percentage or fan power do you use to detach the core from the board? is it the same one you use to reattach it too? I ask this because I have noticed that my hot air station transfers heat better to the boards when it is at low ventilation rather than at maximum. thanks if you answer

Nice work. love to watch your videos thank you.

Always a great vid to watch!

Impressed it worked. Nice job.

I love your sense of humor. BTW you have lowered GPU Frequency not Voltage in Afterburner.

Keyboard cat got me. Another thumbs up for you!

Thanks a bunch for the help on this one! The card has been running great in my fiancés build.

Thank you for another wonderful upload.

Valley Benchmark is a real way to chill after these very tricky repairs, especially when the fixes are a success

Awesome fix and the music is the cream 😊

You earned a like for the piano playing cat synced to royalty free music

Thank you for the video

Informative Video, thanks. does your instruction implies that if the problem solved by reducing the core voltage/frequency then all fault is due to the gpu and no wasting time on reballing and ram chips?

Great work

2:03 Linus moment

I am fascinated by how easy it all seems. Great work! Keep up the great work. Quick question for you: I have an motherboard that has a bent pins on the cpu socket and I was wondering if it something that you could fix? I don't really want the board back, it could be given to a charity or someone in need as I have a CPU for it and memory. It's not cutting edge but if it could help someone instead of collecting dust here, that would be great. Thanks

Amazing job as always! I wish you could fix my old m/b. It got pcb scratches behind it, so it turn on and off all the time. That's the only fault with it.

Considering how difficult (fidgety and hair-pulling frustrating) working with SMD's can be, you do make it look remarkably simple. I don't know how, but you do and it's a joy to watch. Could you perhaps share with us what solder wick you use? I know Goot is excellent but not always available. Cheers mate! 🤘

I had artifacts like this (a bit more intense even) with an RX470 and only lowering the frequency would make it more stable, but driver would crash eventually and reset everything. It was such a pain.

welldone. wish you 1m subs :D

Appreciate your work. What kind of station you prefer to doing this thinks. aixun t3a or aixun t3b? Thanks in advance for your opinion.

Awesome !

your workshop looks very clean sir, can u make tour video?

Such ASMR just by looking at the motion.

That’s crazy! This is around the time my Gigabyte 5700 xt started to slightly artifact

this guy is awesome

I wish cards could come in the same format as the rest of a computer where you can just socket a GPU in there and even upgrade RAM etc, but we know all kinds of problems would come with it, apart from simply not being feasible and would be quite expensive. I didn't know before watching this video that a core could cause artifacts, I always thought it was a memory problem because every time that happens it's simply a memory replacement that fixes the problem.

The cat piano stole the show for me 😆

I first found your channel a couple years ago i think then somehow I got shuffled to the other North numnuts dude until he started to get on my nerves talking about how successful he thinks he is so I've finally found my way back to your channel. SOO much better, actually subscribed this time!

I love the cat theme song!

That's very nice but how do you move the whole voltage curve in the afterburner?

So do you think that was a bad core and not the solder joints? Whta would have caused that, overvolting and copper migration?

Great Job!!! What is the script that you use on Linux? Thanks

The cat was a blast !

cool channel. Sad I don't live in the US but in Austria.

Tysm

What thermal paste brand do you suggest for a hot GPU ?

Thanks for the video! Very interesting. Would you expect the band aid undervolting solution to fix the symptoms for very long? Or does it only buy youa a bit more time before the gpu degrades further?

Awesome video! What is the purpose of placing that wire near the core when you’re removing and replacing it?

Are you around the Portland, OR area?

I had this issue on 2 brand new out of the box AMD R9 280X, after that I switched to nVidia and I'm never looking back - the "fix" was lowering the core clock by some small amount (~100Mhz if I recall)

KITTY!🐈 Ok. Now you earned the thumbs-up.👍😉

Seems like the gpu core suffered electrical migration where voltage going somewhere where it shouldn't that why undervoltaging works temporarily. Seems to me that voltage to core seems to be the culprit where higher voltage is not shown but explains the artifacts relation to voltage set too high or the core hates the voltage given to it after it degraded over time

Thanks.

Same issue on my catmed 1070ti Meaw was on point

but where can you buy a replacement core? or did you salvage it from a different card?

Just fixed a "dead" as is GTX 1060 6 gb, replaced thermal pads, thermal paste, did 3 x furmark test, all good. Heat dissipation is a must with a gpu.

Can you do a vid just on how to lower the voltage?

Very interesting lower core helps rather then lower memory clocks

I really like the music played by the cat

woohoo..another happy customer

Didn't know the core itself can also cause artifacts, i thought it just works or it doesn't. Thanks for this 🙏 very interesting

I have a 2060 Super NVIDIA card that I've been using in my computer for about 4 years. The past 2 weeks i've started having several issues. I am using duel LG 32" monitors. Sometimes 1 or both of the monitors will go black for a second or so then come back. Sometimes They don't come back and I have to reboot. This has only happened twice. THe need for the reboot. Sometimes the right monitor will display a patch on the screen of artifacting. Usually some straight rectangular black and white lines in a pattern. Imagine a chessboard pattern where they are not squares but rectangles. This artifacting is always the same when it appears. The rectangular chessboard pattern. It happens on either monitor. Is this the video card? Seems like a clear case of a video card hardware issue. What do you recommend for trouble shooting this? Thank you

By shifting the V/F curve down you actually overvolted the core (lower frequency for each given voltage step). Great repair as always!

What's that tool you use to replace GPU core?

Could this issue be possibly fixed by just resoldering the chip? Maybe the old one wasn't really that bad. Idk, you should do a video on it

So what do you think was wrong with the core? The solder joints cracked within the core or it is worn out from age? If it is worn out then if i'm not mistaken it would need more volts to become stable. Lastly could a reball with the original core have worked?

1:08 I never noticed till now that Valley does not report the correct current core clock speed.

I love how you kept the jokes in a video to a tasteful level. I've seen some bloggers especially in the Philippines who overdo it by spamming giggles and other meme sound effects to the point of annoyance. :/

1:08 I think you meant to say underclocking instead undervolting. After lowering that voltage frequency curve, the GPU is now reaching a given frequency at a higher voltage than before.

Lol at the keyboard cat. ❤❤😂

this man goes out of his way to reball cores lmao. im starting to suspect all those hours of torturous reballing by hand has made you like it

If the core is the issue, where can you get a replacement??

Hello, how long can a video card last if the chip is repaired like in this video?

Good job.

Could this not be a supply related issue as well?

But why exactly this happanes ? We know that artifacts usually comes from VRAM but in this case looks like comes from GPU Core (didnt know it was posible) but can you explain why this happens ? Thanks

Ohno, i am having similar issues, but only with few games, and it is only a green variation of the artifacts shown in the video, and that ocasionally show up covering only a line in some part of the screen, usually when i have minecraft open in full screen, and i go to exit it to a brouser or click out of the game, the artifact show up in the seccond monitor, where the game is not at, but when i change the game to the seccond monitor and i try to leave it, nothing happens. in phasmophobia it just happened in the middle of the match, in the monitor where i play this time, but once or twice in all the games i played in TABG, the same artifact show up when i open the "group tab"? and only when i open that, i am honestly confused since these are the only moments when that happens, i tried every single program to find problems, but nothing ever happens there. Should i just find a guy that will change pieces off my gpu? is there something related to temperature? should i test with a specific program? i just want some advice here ngl.

Nice.

im having same issue with gigabyte 6800xt oc, do you think its the brain on the card causing this artifact too?? are they easy to get hold of???

deteriorated memory controller. owner of the card was very luck that you had that core in stock. Good job mate.

Hi tony, would like to ask what solder tip you use and solder wick and if it has a technique, becuase mine won stick the lead , i mean the lead on pcb doesnt sucked by solder wick

my rx 6600 had artifacting since day one, lowering stuff in MSI does nothing, clean driver install neither, as long as i have no driver there is no artifacting. as soon as I install one its back. i dont know what to do

How do you price this fix? (don't have to get into exact numbers if you don't want to) The way I see it replacing the core is like replacing the engine in the car. It's so expensive and there's no easy way to buy replacement cores so most of the time a bad core = no fix.

GPU artifacts *exist* owner: its the monitor, right? GPU: ... owner: its the monitor, right?

LOL love the piano cat

Yo can you tell me whats wrong with my pc ? - i have an rx470 4gb version nitro saphire , -i use atikmdag for driver issues because they dont appear themselves on windows so i have to use this program. - i dont think its because of the driver problem but after the pc starts and gives signal after 1 minute the screen is full of artifacts and then somethimes restart sometime gives BSOD and restarts and sometimes it just goes on worlking without restarting. The artifacts arent individualy showing they appear in a moment and then do the restart thing they are on the whole screen and they are diagonaly out ...

I got an unused 2070 that stops any system it's in from booting. You think it's worth sending in for repair?

What's your opinion on spatula soldering tips to clear up solder on the GPU?

i didnt really understand what the problem is. bad gpu passed through QA at factory ?

hey, got hands on friend's Aorus 2080 recently, which turns instant off(fans max) at about 70´C?, what could be the issue? (me having 850W PSU) thx

WOW this guy is the REAL deal ! Replaced the core! WHAAATTT

Would soldering more vram to a A770 8gb (or another card with a higher vram version) work the same as a card that came with 16gb from the factory

1:10 That is not really "lowering the voltage", you are shifting the V-f curve down, which results in a combination of lower max. clock and higher voltage at lower clocks. At no point along that curve does that result in a lower voltage.

Why didnt u just reheat the old processor? may be it was just cold solder joints

could a faulty/not strong enough power supply also cause this? I recently got a new graphics card and all of a sudden I've got loads of artifacts in most of my games, and It's been a while since I've upgraded my power supply.

Would reheating the original core or reballing be worth a try before replacing?

what did you do to get rid of the artifacts. i dont have money to send my pc anywhere and i get the artifacts in almost every game i play
