ASUS Demonstrates New ROG 290X and 780Ti Matrix Feature: Memory Defroster For Extreme Overclocking

[KakaoDj]

ASUS ROG article (not really any info, everything is in the video)

 

So this is basically a feature that defrosts your memory when your card is under LN2 to avoid any bugs that comes from cold memory (i have no idea). You plug in a molex connector and turn a switch on, and then the card gets heated up around the GPU, but not the GPU itself of course.

Not really for the average user or gamer, but a cool feature nevertheless. I have gotten my hands on some cheap LN2, and i would love to test it on a GPU, but my 560Ti is not really my ideal test subject  :lol: Good thing the Matrix cards have this feature if i deicde to go for it 

 

The video contains super epic music, so strap your hard hats and pants on. (That freezing sound effect doe)

I will pass thanks! Oh and your source link doesn't work

[Shd0w2]

shit..

What is the point in defrosting the memory?

[minimalist]

That's.....beautiful.

This was posted earlier, sort of.

Wouldn't the memory produce enough heat to defrost itself? (I guess not )

I might not get frosty like you see in the video, but it would still cause a problem.

Tho my knowledge a cold bug occurs when the soldering loses contact (due to flex caused my large temperature difference.)

How about instead of putting in features that only .01% of the community will use and doing it for only headlines. They focus on things that matter like a better cooler

[consoleconvergence2pc]

EPIC

[wtfxmitchell]

i like it when he takes off the cooler that there is not thermal paste

[brownninja97]

yeah, no.

[nicholaswillems]

Yeah maybe they should sell coolerless cards for overclocker competitions but it's kinda pointless to have when you're not putting liquid nitrogen on your card until it dies.

[AHaskin14]

for those balls to the walls days when you overclock the hell out of your card.

Didn't you read the OP?

This reminded me of Crysis for some reason.

+1 and to be frank I'm pretty sick of manufacturers including liquid nitrogen 'features' on consumer boards. NO ONE USES THEM. If people want to use LN2 they don't need a beastly air cooler or backplate etc. They just need a graphics card, all bear and naked

[Alandesu]

Wait, as it defrosts, doesn't it melt and change into water? Doesn't water short any of the circuits?

That's like the first thing I noticed lol.

Don't by the matrix cards then. They are really only meant to be bought by people want to overclock the shit out of them, not for people who are going to put them into a normal system and look good. They still put the nice cooler on the thing because it makes it easier to sell to idiots who don't know any better and just by the most expensive thing or what looks the best.

[Ruijin97]

wouldnt there be moisture created on the pcb doing this?

I want to know the truth

[mooommo]

I want to know the truth

the idea is you turn it on before your gpu freezes

[sTITh]

no,

the idea is to keep the space around the memory warmer than the area around the GPU.

 

normally, working with LN2, you have to put gum-like material all over the place, to protect your circuit from shorting out due to condensation.

 

That video were for marketing, not to make a true bench-session with LN2.

 

And to show the effect of this new feature, they let the water condense and freeze, and than melt again, directly on the card.

Because you are using LN2 to test or to compete in benchmarks doesnt mean that after that you throw the card in the garbage... so if you like to return home and play a game with that card or just power up your pc that doesnt have onboard graphics you need the card to be able to work without LN2 as well also you may want to sell the card.. who whould buy a naked card? well I suppose some people but having it fully autonomous will increase the market margin.

No atleast not pure HO2 (clean water) its not a good conductor... water from your kitchen fridge etc isnt though pure HO2 and has also some other stuff in it that make it a good conductor.

The problem with ice formed from the HO2 molecules taken from the atmosphere is not its conductivity its that some parts of the pcb (like resistors or capacitors) do not perform as they should in lower temperatures  and thus they affect the graphics card as a whole.
