Don’t know if this comment will go thru but here goes. I notice when work is done with hot air practically noting is shielded. The pieces of a coke can over the memory chips are a good start but doesn’t prevent the hot air going under the chips. When I used to fix laptop video chips I always had a custom shield for the entire motherboard made from folded aluminum foil and aluminum tape around the cores. After many repairs I had quite a bit of shielding templates that prevented unwanted damage to other components and only focused the heat on the chip I had to work on. Would suggest getting into this practice as it’s not hard to do for GPU’s as the core size is always going to be the same, adjustments will need to be made for the smaller 70 series and below cores well as memory chips. Can start with one and adjust as needed but always using aluminum tape around the components as close as possible. This will prevent any errant hot air from damaging other components. Be glad to show pictures of the collection I have on the Discord or DM if you’d like.

@@btwbrand I already said that about the coke cans. Doesn’t matter all of the board should be shielded except the component being worked on. Takes 10 minutes to make something up and saves hours of aggravation when something gets damaged trying to chase down the new problem. It takes very little deviation of heat say attaching a new memory chip or core to melt the solder of the components nearby especially the outer BGA solder balls. No reason to make more work for oneself when it can easily be avoided, remember the laptop case he melted cause he didn’t think the motherboard needed to be removed? 5 minutes of removing a few screws would have prevented that debacle and that’s what happens with shortcuts.

I have information. I looked into this case and made some interesting deductions. The first of which is the fact that the number "1" in the BRSFT column is obviously the norm, while number "2" can be ruled as the odd ones out. Also, the numbers "2" directly correlate with the low numbers ("8" and even "0") on the next column to the right, name "INTPL". Then you can also notice that those low numbers on INTPL show a tendency to occur with pins CA4 and CA5 on the column that goes to the left of the numbers 2.... Now here comes the interesting part; CA4 and CA5 are PRECISELY the pins at the center of the memory chips according to the GDDR6X ballout data. In other words, 4 chips show a low number of "INTPL" with an amazing coincidence in the fact that all 4 chips have troublesome numbers exactly at the center of their ballout. I think this is proof enough to show that the problem is NOT the core, but rather your heat delivery on the memory chips. Your heat is not properly melting the balls at the center.

I made a comment before this one and deleted it. I had jumped into a conclusion. But I still think the power delivery could be at fault even after a second and third thought. There could be a component that got degraded. I know how crazy this sounds, but considering how good you are at reballing chips this would be a great opportunity to learn something by taking that core off its board and putting it on anoher PCB. At least that's what I would do, so that I could test the core with a _known good_ power delivery circuit. If I'm wrong, I kind of waste a couple of hours of a learning session, but if I'm right, I could make thousands from buying "dead" 4090s.

My advice is to not touch chemicals with your skin under no circumstance. Use a brush, do not use your finger. You're poisoning yourself bit by bit by touching it and allowing it to be absorbed through the skin. It is in tiny quantities but if you absorb 1/1000 of a gram for one memory, doing 1000 memory chips would give you a 1 full gram of absorbed poison. You need to re-think your work protocols. Your health is by far the most important thing.

One guy had to wear white cotton gloves laced with lotion for a long time to grow back his subdermal skin layers. It's no joke. Silicone products are the worst.

So the idea of this repair was like this? The memory chips appeared to pass but it was possible they have sporadic issues or under different loads had issues. 2) There could have been a connection problem of one of the pins of the core and the memory. But what was concluded is the core had developed physical damage so that was that?
@northwestrepair

I didn't see any physical damage anywhere. The memory errors were misleading. Information on the internet about the use of NVMT is vague at best and I actually never really bothered to investigate anymore than I already have prior to this point.

I am serious when I say STOP overclocking graphics cards. Rather underclock them. I underclocked my 4080. I lost about 3 to 5fps but my wattage is about 90w to 100w, games fully playable, also temperature is about 60 degrees. If I dont underclock, card easily pulls 180w to 250w, and runs close to 80 degrees. Also, use the support on the back of your card. If you dont have a support, let your case rather lay flat, the stress on the board with this heavy cards causes problems with the PCI Express slot, and card cracking. If the card pulls on the slot, it can short itself per accident, and you lose your core or memory.
