Note, it's probably float glass, not tempered. Tempering glass introduces warping as it rolls on/sags between ceramic rollers. Float glass is extremely flat because it's suspended.

[off-topic] but just saying there are shampoos and other products that reverse grey hair.. I found it by accident. Basically you need supermarket hand sanitizer that has ethanol, Vitamin E, and Aloe Vera... your greys will turn into browns on the fly :) Doesnt work with white hair, you need to pull those out and regrow back into brown.

Considering how long biso said the lapping process takes and the amount of precision required, I wonder if it wouldn't just be simpler to make a jig to hold the card in place while you do it? If you can keep them parallel you should be able to get away with just a weight on the lapping abrasive and then you can pull it back and forth or even use a motor or something to help you do it. Then all the work would just be the initial work holding and changing out the abrasive every once in a while.

@mromutt Жыл бұрын

I was picturing like a plastic holder/tray that has perfect holes and cutouts of every component so it fits it like a glove and then you use that in a sled. I imagine if evga was still going to make cards they would have eventually gotten to that stage. I wonder if 3d printing could be accurate enough for something like that (that you could buy non commercially).

Awesome video. A trick I learned doing some guitar luthier work may be very helpful here... Instead of using an adhesive pad, apply slightly oversized masking tape to the glass with a vinyl squeegee, credit card, etc. so it's perfectly flat. Then quickly apply a fairly even amount of super glue so a thin layer will cover the majority of the glass area. Any super glue will work if you're fast but low viscosity cyanoacrylate with a slower set time is ideal. Now place a piece of sandpaper approx. the size of the masking tape. Lift one side while firmly pressing it down to all edges of the glass with your palm (a roller is better but shouldn't be necessary). The pressure will ensure the entire surface is covered and since both the sandpaper and tape are slightly oversized, the glue shouldn't leak out unless you used wayyy too much. Finally, just trim the excess and you should have perfect coverage with no lifting edges. It should only take a few minutes with a little practice. The magic of this method is it can be removed in seconds leaving no residue by simply peeling the tape off. Then just repeat the process with your next grit. This is significantly cheaper than big adhesive pads with even less compression. The other advantage is it works on basically anything. I've even used it on a sharpening stone (which are typically very flat) to lap a vapor chamber surrounded by mounting posts (don't ask). Bonus tip... it's even easier to remove if you use low-medium tack tape and fold a little excess over one edge before applying the sandpaper.

This approach Is not flat enough

@JJFX- Жыл бұрын

@@laughinginthe90s How so? The only difference is thin tape and glue instead of an adhesive pad. The most variance will still come down to the sandpaper itself. EDIT: I can see why people visualizing this would assume it'll lead to a compromise in flatness but I suggest giving it a try first. You might be surprised how well this actually works when done right.

@pino_de_vogel Жыл бұрын

So not to be a prick but a honest question. How do they make sure the actual sandpaper is 100% flat? It ultimatey is paper with glue on it and a sanding dust coats the glue. In my mind there is no guarantee thnat is 100% flat by itself. And you can take this further. Considering the sandpaper is 100% flat. The glas it lays on does not have to be flat depending on manifacturing tolerances/process. But even if the flass is perfectly flat who says the table the glass lays on is? Glas after all is a amorphous solid making it not 100 solid and can flex to the curves of the table. Sandpaper + glass factory tour next ?

Huh? They did do that... on the Kingpin PCBs. Which they don't make anymore, because they don't make GPUs. The KP 4090 we saw was a hand-made sample, which is how they have to figure out what to put on the final retail samples. They're not making retail cards anymore. That's why.

Sanding down a die substrate is rare? I thought it was wide-spread and think about doing it sometimes. It could be a huge temperature and power saver for a very hard working home/game server - I mean think about it. I also think about the thermosyphon CPU cooler just so that I can have a friggin HUGE air cooler. Having both must be crazy.

@gnextras Жыл бұрын

You would never sand down the die's substrate, just the die (just clarifying in case someone tries that, haha). Yes, it is very rare, of course. If millions of people buy GPUs a year and fewer than 100 sand it, it is rare.

@stoneymahoney9106 Жыл бұрын

I don't know if you missed the part of the video where they explain why they sand the die down - it's not for a temperature improvement, it does nothing for the actual operating temperature of the die. Nvidia deliberately don't make the die perfectly flat when it's sitting at ambient temperature because once it heats up under normal use it warps, so they make the die very slightly convex so once it's up to temp it becomes flat, so *lapping the die would actually make temps under regular use worse with ambient cooling* as the die will become concave and you'll lose all your contact surface area. The reason XOCers need to do this is because they use LN2 to chill the card down, effectively causing it to warp in the opposite direction, becoming a LOT more convex and causing the frozen thermal paste layer between the LN2 pot and the card to fracture. They then have to tear the whole setup down, get everything back to safe temps, repaste and remount the pot, and start again, wasting lots of time and potentially not getting as good a pot mounting as previously. Die lapping is purely a practical consideration, not an overclock performance one.

@Mom19 Жыл бұрын

If you aren't extreme overclocking, its useless. It's only beneficial if you can actually go full pot because the Die architecture can withstand these kinds of low temperatures. But the paste etc doesn't, if you loose contact because of the die warping, your paste could crack. Loosing surface contact, generating hotspots and loosing performance. For daily usage under any normal temperatures, this won't help you anything. Atleast for GPUs. For CPU dies I would say it does help you a little bit but seriously you already gain so much more by using direct die + LM for cooling that this minor difference isnt really worth risking your silicon
