What is the point of this video?

[MrTomnus]

So I came across this video on youtube and it intrigued me. I watched it and then I thought "what was the point in that?" They didn't show any thermals at all, what clock speed the card was running at and voltages etc.

 

Am I right in thinking the video was simply to showcase the defrosting properties of A HOT GPU?!?! 

 

I still don't get it.

Just marketing to show how advance their GPU is.

Isn't it really bad to let water vapour condense and then freeze on the circuitry on the card?

[s3ns3]

yes that looks a showcase of the cards defrosing properties under LN2

[flibberdipper]

So you can keep the GPU cool and the memory moderately warm when you're doing Liquid Nitrogen OCs.

But who has access to liquid nitrogen?? I'm certain its quite expensive and you'll have to keep applying it to keep the card cold...

That kinda makes sense. So this is just a video to make people who know nothing about GPUs go "WOW...." ?

Pure water itself doesn't conduct electricity. Only when there are mineral ions in the water (such as calcium, copper etc, commonly found in tap water) does it become conductive. The condensation will do nothing to the card. The freezing may do, since freezing water expands. So I suppose if enough got into the circuitry then it could blow them up... I don't know

To let extreme overclockers know this feature exists and to let those who aren't extreme overclockers know this option is there. *meh*

Surely water vapour from the surroundings would have ions in it. Isn't that why they use paper towels on mobo's when doing extreme overclocking?

It is to show how the GPU can defrost the memory on the card in case of cold-bugs, as stated in the description.

I probably just heats up the VRAM so the system wont crash when LN2 OC:ing, the cold isn't a problem for the GPU core so that is left as it is.

 

Basically a VRAM warmer feature.

I think it is actually quite cheap it's the bottles that cost, refilling is cheap as well.

[qwertywarrior]

why just add plado or vaslin ?

[s3ns3]

no. this is for extreme overclockers who keep trying to break world records

[_ASSASSIN_]

when doing liquid helium or other forms to overclock, you want to have it cold but not too cold.

[MrTomnus]

Um, I haven't seen that kind of thing being done myself... But I guess the water vapour does have the potential to have some ions in it. Generally if you are evaporating water, any ions with it will not be taken as well - that's how distillation works. I wouldn't have thought it was a huge risk though.

Okay, can you explain what a cold-bug is? I think that might be my problem.

I didn't know this was a thing... I haven't known anybody to overclock a card and run it under liquid nitrogen. Is there any point to that? Or just for e-peen?

[UnknownEngineer]

I am not entirely sure, i think it is when the ram simply freezes, it becomes less responsive, that's all i can think of.

BRB googling.

EDIT: All i can find is that the cold causes bad contact in some places due to a bad solder/sodder. This is just a cut wire in essence. Basically the wiring on the PCB gets so cold the when it's size changes (by an incredibly small amount) it stops making contact in areas were there are small defects.

I am not an extreme overclocked so this is all i can give from searching.

Anyone else have some input on this?

100% epeen. It's not convenient. The only convenient of way of sub-zero cooling I know is phase-change.

That would be a problem... That's the opposite of what caused the YLOD on my PS3 So by heating the VRAM is attempts to expand the connections to their normal size. But how is this not an issue for the GPU? Because the internals aren't soldered?

Thank you for searching by the way

Haha, okay, I didn't think it was. Just makes me wonder why people go through the effort really...

Water vapor condensing from air is pure water, so it doesn't conduct electricity well. 

Dust, however, would make it conductive, and dust is pretty much everywhere but a clean room.

That's because normal people don't do it. Even average enthusiasts don't do it. This is literally for the 0.0001% of PC builders that push things to their breaking point, and it's never for actual performance gains. Pure e-peen. 

If there is someone out there who runs their normal rig with LN2, he has too much money and free time to care what others think.

 

[ericlee30]

Its a defrost mode for people that do LN2 cooling, pretty neat technology if you ask me.

[LogicalDrm]

You can get that for free at out Unis Dept of Chemistry If you have own canister for it. Now dry ice... thats expensive.

[Faa]

The main reason of this technology is because you can't use a heatgun on memory modules. When you drop LN2 on a cpu, temps get around -120° orsomething and it would barely post so you just use a heatgun to get it somewhere around 50° or whatever you like, gets hot again drop more ln2. CPU's can handle a heatgun since they use metal covers
