- In this video, we tackle a unique and puzzling case of an Inno3d RTX 3070 Ti that wouldn't get detected, had no fans spinning, and emitted smoke. Upon inspection, I discovered a GA102 Die typically used in RTX 3080 and 3090 GPUs. Initially, I thought the customer had mistaken this GPU for a 3070 Ti. Watch this video to uncover the secrets of diagnosing and fixing this unusual GPU issue. Don't forget to Like, Share, and Subscribe for more intriguing GPU repair stories!

Man!, you are a badass techinician, I love this channel, Cheers from bumfuck nowhere, Mexico.
Thank you 😁
Nice video, thanks man. As for the GA102 variant, it's a version released in late 2022.
Thank you 😁. It took me by surprise.
Interesting 🤔
Apparently its only got 8gb ram... and its slower than a regular ti
Amazing work, I'm surprised it having a GA102 core also, I think maybe it was a 3080 core but defective or did not meet spec so bios flashed maybe to be a 3070Ti,I have a 3070Ti and it uses GA104 (LHR)...I WONDER if that 3070Ti you have can be flashed to a full 3080!
Yes that's what I thought. GA104 is what I was expecting. 😂
I’m pretty sure nvidia disables the the extra cores at a hardware level, in the past there have been chips that they only disabled at a software level and you could bios flash them to a higher tier gpu. Safe to say that lessons were learned and now unfortunately we can’t take advantage of that.
Yes they are dissabled on the core. 😁
@@user-fo3yy7ql8o damn, there go my hopes on a "free" tier-up upgrade. Yet though, do you recon it would be at least possible to solder on a few more memory chips to expand the 8GB memory bottleneck?
@@T3m0xx probably but you would need to find the exact memory chips . ive seen people double the memory in some gpus by replacing the existing ones with higher capacity memory
The " NVIDIA GeForce RTX 3070 Ti 8 GB GA102 " was the ONLY card with GA102 that was put out to the public, I don't know if you can slap a 102 in a regular 3070 TI like my Zotac AMP Holo since its 104 and might not have the power.
I'm VERY interested in how you do the 3070 Ti memory upgrades without messing up the cards, you have fantastically steady hands. Great work and awesome videos!
The GA102 cannot be installed on the GA104 slot. There is a size difference and the circuit is also different. The power requirements are also more. GA102 is too large for the regular 104 slot. The whole PCB will need a change.
I think u missed somthing , in heaven bm the gpu total TDP is only @ 40% , somthing is wrong !
Heaven does not utilise much power. That's the reason I also use furmark to test power. Heavens I ran to check for Artifacts.
Sir i am from india i have a problem in my 1080 ti its power cable get burned 😢 today in afternoon
It's not woring 😢
It's warranty is also over
It can be fixed. I assume the power connector is burnt. It can be replaced. The link to book your repair is in the description of the video.
@@GraphicsCardRepairs-tk7ql ok sir thanku
GA-102 with 8 gigs of memory.... I hate Nvidia so much for shit like this.
I was surprised when I opened it. I did not know they started using GA102. 😁
@@GraphicsCardRepairs-tk7ql I did knew about that, but never actually seen one.
They are very rare and were produced near the end of the production cycle. That GA-102 is so heavily cut down that it almost makes me cry 😢
I have not yet had to replace an inductor gone bad, unless related to core or vram. I have never seen a GA 102 on a 3070 Ti. Looks like Nvidia is just recycling their silicone LOL Very nice video Frazer!
Thank you. 😁. It's a rare scenario to replace an inductor. I was surprised.
@@GraphicsCardRepairs-tk7ql Especially with a GA-102 core LOL Recycling to save the earth I guess 🤣
🤣
Happened to me once too.
I think it's the same kind of inductor, too small to handle the current.
@@northwestrepair I think that's exactly it.
Yes just bought two new RTX 3070 TI with GA102 on them cards, got to replace the thermal paste with bit better. Awesome videos you do all ways.
Thank you 😁
But is the performance of the 3090 there ? Or its just not all 3090 cores and shaders used ?
Very very good! I would never had awaited an open choke. Crazy! Never saw that before! Good work! 🙂
Thank you 😁
I WONDER IF THE ONLY THING HOLDING IT BACK IS POWER LIMIT?
Part of the die is also disabled. It has lesser SMs and cuda compared to 3080. 😁
Hey mate, i have a rtx2060 super and a gtx 1080. i would like to get fixed, but no one in Australia will do it as we don't have any repairers here. Would u be interested in fixing them?
Sure I can fix the GPUs however you will have to consider the shipping cost to ship it to Dubai and back. After you check the shipping costs involved you can book your repair by clicking the link in the video description. 😁
@GraphicsCardRepairs-tk7ql i have checked the shipping. It's not overly expensive. Is there any import duties i need to consider for u to receive them in ur country as well?
There is 5% import duties on product value above USD 250. This is the declared value you will enter on the invoice you will attach. Else the amount is USD 15.
When declaring declare it as damaged. Avoid over valuing the GPUs.
Hi i wanted to ask if the chip is dead is it replaceable?
I assume when you say chip you are referring to the GPU core. Yes the core is replacable however you cannot buy new core. It iss either swapped from another GPU which has a working core and other parts not repairable. This can take a lot of time depending on a donner card to be found. There are alternatives like buying from Aliexpress but i would not recomend this option. 😁
as long as the under chip chamber isn't breached you can soak the chip and move the wax around under the die to get the chip to work again
Thank you for sharing 😃
@@GraphicsCardRepairs-tk7ql shiney part down then roll around after preheating like spreading fluid inside a glass to coat the glass , try the card again , it might even fire up and give a screen. just keep going
do you think you could upgrade ram in a 4090 lmao
No Imao. 4090 already uses 2Gb modules and it has only 12 memory slots. 2Gb i the maximum capacity available.
@@GraphicsCardRepairs-tk7ql thanks for the reply thats what i was wondering
Much like my 1060 with GP104 core. Isn't 1060 supposed to be GP106?
I was totally caught off guard by this card. Its typical Nvidia I guess.
hi sure can you tell me software name for datashate mobo plz
I think you are referring to the MATS and MODS software.
@@GraphicsCardRepairs-tk7ql i mean samone show Schematic circuit diagam
Yes, schematics and boardview play important roles in understanding the circuit. Its not available on the internet. You will have to join a discord server of Richard (Learn Electronics Repair) or Tony (Northwestrepair).
Ask the boss of all bosses to disassemble it next time!
😁
Great work, learning a lot from you
Thank you 😁.
very nice video, awesome skills. thanks!
Thank you 😃
This is so cool!!!! How much would it cost to get my 4070Ti Super 16GB upgraded to 24GB? Is it possible? (i do a lot of AI stuff)
No 4070 ti already uses 2gb module which is the maximum capacity available. As of now an upgrade is not possible on any of the 4000 series lineup.
@@GraphicsCardRepairs-tk7ql Ahh I see. 🫡 to you tho, brother, I love watching your videos. I've been building computers since I was a kid circa 2000 but i never got into this level of repair - I find it fascinating and super cool. I didnt even know it was possible. I wish you continued success!
Thank you brother 😁
Awesome video
Thank you 😃
Great job!
Thank you 😃
some wizard type work man ,earned a subs where are you from
I live in the UAE from India.😁
@@GraphicsCardRepairs-tk7ql yes i guess right, your tone ,kasa he ho waise? mai maharashtra se hu

Awesome Work🎉
Thank you 😁
imagine if he said what the sigma
😁
what is a cost on that repair??
The price of the repair will depend on the GPU. The prices can be found at the link below

hi Sir i need some memory can You please courier?
You can buy it from AliExpress directly. Unfortunately I don't sell memory. 😁
@@GraphicsCardRepairs-tk7ql import from AliExpress is not possible in india sir.
You can try mouser India Website
Where r u from? I hope you are from Bharat..
Bharat!!
Welldone sir...❤❤❤
Thank you 😁
Released 3070ti's with GA 102 in late 2022.....
I did not know that. This card took me by surprise. 😁
But how does it perform ?
I felt it was same as a normal 3070 Ti. I should have done a benchmarking test like in games. That would have given a clear picture. Its a miss.
Nice, can you share the full die label?
Unfortunately the GPU has gone back to its owner. This repair was completed on 20th May. Let me see what I can do. The owner is a nice guy 😁
@@GraphicsCardRepairs-tk7ql no worries would have been cool to do some research on that 😅
Nice bro. ❤
Thank you 😁
Great work BRO
Thank you 😁
It was a GA102 that didn’t pass quality control tests and was binned as a 3070 Ti core.
AMD and Intel do this all the time on bad yields.
Just as a example I had a AMD Phenom II 965 Black X4 which was labeled as a quad core but started its life as a six core CPU that failed QC so two of its cores were disabled then repackaged as a quad core.
Some motherboards could unlock the other two cores which I was pleasantly surprised when selling as I sold that CPU used after two years of use for more money then I paid new for it.
Wow. Thank you for sharing 😁
@@GraphicsCardRepairs-tk7ql Wouldn’t surprise me that Nvidia was having serious QC issues as we all remember the shutdowns of late 2019-2020 so they probably may have just used what was available at the time by disabling shaders in the SOC.
Out of curiosity have you seen a lot of EVGA 3090 Ti failures? They were releases early 2022 so hopefully the supply and QC issues had improved by then.
Thank you.
So far I have not received a single 3090 Ti for repairs. I have received all other GPUs except for this one. Maybe they really designed the circuit that well. Time will tell. 😁
@@GraphicsCardRepairs-tk7ql Thank you for the reply.
Very nice video sir.
Thank you 😁
nice
