I've just soldered completely different memory to old 7600GS (half capacity, but can overclock to higher frequency) and it's shock for me that it normaly booted to windows with no artifacts and I was even able to install drivers, I soldered only 1 of 8 modules, I am just trying what it's gonna do. It's the worst 7600GS (500 MHz DDR1 and no oc is possible) but I have one broken GF6600 where those DDR1 modules were able to go up to 700 MHz and it was a massive performance boost to OC it. These old DDR1 modules have still those oldschool contacts, I don't really want to play with BGA chips, I tried it several times and I mostly damaged it.
Hello, firstly congratulations on the work. You have to take into account that this batch of Micron memories where it starts with "8" came with a factory defect and all need to be replaced to lote "9"
good work. would it be possible to use this technique to upgrade a Tesla P40 from 24gb to 48gb. I realize it would have bandwidth issues, but I'd like to load very large models on them, even if they run a bit slower.
For some reason when ever I try to remove a memory chip the solder does not melt. I have been hearing one up as I am writing this comment for like 10 mins and at 713f and it is still not moving. What am I doing wrong?
Temp and airflow for re-balling with paste? The stencils always bow and bend up when I try to reball with paste and stencils. Even as low as 250C. Nice work.
hi mate what program did you use to determine witch of the vram is bad? got rx 6700xt here so would be amazing to find out what to use to see how many to order :D
Hello friend, what brand and type of paste solder do you use? I'm from Brazil, I usually do the reballing of memories with solder balls, but it's more laborious, I still haven't found a brand of solder paste that works well for reballing. Thanks for the video!
Hi, is there a way to know what those little components on n17e-g1-a1 are ? My predator helios 300 GPU has one left, but dont know if it is a transitor or capacitor or what... can you help me?
That would be because it is extremely variable based on your station, air speed, ambient temperature, size of nozzle, and even less obvious things like angle of hot air and aim. It is best to practice on donor boards to see what temps melt the solder yourself. In my case, I set my station to about 460c with pretty high air. But I haven't actually measured the actual output temp so that doesn't really mean much for the next guy.
Some you solder wick. I don't use that for this application as I don't think it is necessary here. Yeah, I just 'clean' by flattening with lower melt solder.
Hi, I have only recently started my interest in reballing gpu components and diagnosing gpu problems and I was wondering what and where can I get all the equipment required for this kind of work?
Are you using _flux_ to melt the old chips off? Liquids conduct heat a helluva lot better than air ETC, so the flux drastically helps speed things up, keeps you from toasting components and cleans the oxides off the connections for a reliable electrical/mechanical bond.
@@TEAMCREAM_96 the PCB board _IS_ an "insulator", both electrically and thermal too! Try soldering connector fittings on the ends of really heavy coax for amateur radio towers.

You can see it twitch usually or you can start to see solder pads around it starting to liquify. The way the flux bubbles also kind of tells you. Mostly I just know now because I have been soldering for years.

I don't tend to buy extra equipment when the methods I have already work fine. Some people like to have a lot of equipment, but I prefer to work with what I have. Just preference though.

Good job mate 👏
What about upgrading VRAM on a 4070ti? With the price gouging from NVidia...
Phew, for a second i thought you were replacing with more 2018 micron. Thank god it was 2019. Lol
do you still do GPU repairs? My EVGA RTX 2080TI got the imfamous Error Code 43
do you think its easy to add more VRAM by swapping the old chip with new model one or maybe increasing the frequency?
Possible but difficult, should mod the bios as well.

How do you determine the balls on the BGA have reflowed ? Are you looking for self alignment as the meniscus pulls everything into alignment ?
hi mate what program did you use to determine witch of the vram is bad? got rx 6700xt here so would be amazing to find out what to use to see how many to order :D
Do you use a preheating pad when removing memory modules or just preheat the board using the hot air station first ?

I don't have any specific brand I like and will just use an 183c temp solder paste I can find for this
Hi,
Was wondering if you accept a gpu from other country for repair?
Hi, i want to ask,can dual gpu from radeon 6990 or Similar can be replaced by 2 gtx1050 no pin chipset or similar ? It will be good experiment .
reckon you could put little comments on what stuff you're using
Hi, is there a way to know what those little components on n17e-g1-a1 are ? My predator helios 300 GPU has one left, but dont know if it is a transitor or capacitor or what... can you help me?
what temperature you are using when you desolder?
thats what i wanna know too
I was near max on my hot air but I don't remember specifically. I adjust depending on if things are melting or not.
tons of videos on internet, and still not find anyone talking about temperature of air station
That would be because it is extremely variable based on your station, air speed, ambient temperature, size of nozzle, and even less obvious things like angle of hot air and aim.

But I haven't actually measured the actual output temp so that doesn't really mean much for the next guy.
Alex from Northridgefix uses 500 degrees with max air pressure
I use 200c for pcb heater and 400c for hot air but my smaller hot air needs to be at 450c, every station is different.
@@iBoardRepair esque je peux trouver une personne comme vous pour augmenter la Vram de ma rtx 4070 de 12go passez a 24 et a quelle prix
what is the name of the paste that you used at 8:39
MONSTER 👏👏👏👏👏👏🔥
Plz tell which direction I need to place my chip to install I was confuse
Can you fix the ram? or always need donor vram?
Hey aaron I replaced the Vram on my 2080 super and now I have more errors than I did before on that same memory. How can I fix this?
You might have bad memory, you might have replaced the wrong one, you might have not soldered it on well, you might have a dead core. Who knows.
Are vram chips reversible or is there a specific way they have to go onto the board? (Im talking about the rotation of the chip, sorry bad english)
They are not reversible. They have a specific orientation. There is a dot on the chip and a mark on the board that specifies orientation.
So do you use flux and solder again to clean off the pads? and ive seen some people use what is called a wick to do that
Some you solder wick. I don't use that for this application as I don't think it is necessary here. Yeah, I just 'clean' by flattening with lower melt solder.
What is the name of that thing you spray? is it blowing air only? Hehe
Where can I buy new memory chips? I got a faulty 6800XT, pretty sure is a VRAM failure

how can i tell which chip is bad?
What do you have the heat on your air set to when removing and replacing the chip? Thanks for the video.
I don't remember, but it was close to max. I adjust temps as I feel I need to rather then working with set temps.
@@iBoardRepair thanks
How do i actually get another chip though
What was the Issue on this gpu?
How much would this repair cost me?
Yes same as well, would like to know how much for the reballing?
Do you repair original ram chip or do you replace from a Donor board
I replace with a donor
what temp do you use for the soldering of the chip
?
It is individual for each station. I actually don't remember though. Probably 450 - 480c
@@iBoardRepair thanks 😊
Was it giving error 43
I need a vram replace on my gpu. Anyone know of a mail in repair man?
Im trying to do this but i just cant get it hot enough to melt the solder

@macgyver5108 yeah i was, i ended up having to heat the board up with a toaster oven. I ended up saving two 2080tis

What kind of solder paste are you using ?
Just some leaded solder. 183c melting temp iirc.
