Gtx 580 Dry ice run

[Lays]

After the 480 DICE session I had yesterday, I figured I'd fire up my 580 Matrix and give it a go as well, with the leftover ~5 pounds of dry ice I had.

Card didn't scale very well after 1150 mhz, added lots of volts to get it to do 1172.  Kept failing 1175+ mhz.  Needs to be colder I think.

Holy crap the ice forming on the back of the GPU PCB!

[Darkman]

Gotta go fast.

 

When are you going to get enough DICE to run your 980ti?

what is the benefit of using dice instead of LN2?

is it like cheaper or easier to get hands on or something?

 

I've noticed you exclusively use dry ice for your overclocking

yeah, that's the humidity in the air, it condensates

10 pounds of dice for me is ~$13 USD and lasts ~5 hours or so of OC on a CPU, maybe 2.5 hours on GPU.

 

 

A "Liquid Nitrogen Dewar" (the thing that you fill with Ln2 to transport it) is upwards of $300 depending on the size / quality, some can be over 500$.

Then Ln2 is around $0.75 to $3 per liter, depending on where you get it.

 

 

Ln2 gets MUCH MUCH colder though, over -100c colder, but the price is really steep..

What voltage did you pump through it?

Ahh and holy shit lol

I would guess getting that could isn't too beneficial (LN2 vs dry Ice).

But holy cow man that's some baller stuff you do.

Na, Ln2 is much better.

 

If I was on Ln2, that 1172 mhz would of been 1300+

I knew that much, it just that I don't see a lot extreme overclocking. Most desktops I see/build are usually out of necessity and practicality.

LN2 is very beneficial, just ask HiCookie about his 7.1 GHz on Ivy Bridge

Not bad for Fermi ehh, I wonder what my Lightning would be capable of since it has an LN2 BIOS.

oh, there was a really great pic K|NGP|N posted on twitter he was running a 3-way or 4-way Titan X on LN2 just after they were released, like all PCBs were fully covered with huge frost blocks and he was doing LN2 on CPU and RAM as well that looked totally crazy

 

yup, found one of the pics:

if you look close enough it looks like the frost build up is pulling one of the capacitors out of the PCB

 

there were more crazy ones but can't get them....

Nice job! @Lays I've always wanted to do a subzero bench myself but unfortunately I don't have any old GPU's lying around

sounds reasonable,

just out of curiosity maybe you know some links to guyz or garlz doing it with helium? is that even a thing?

It looks like one the capacitors got pushed out by the expanding ice.

yup going to the extremes

How the heck do these things even still work?

cheaper is one of the main one, Dice is easier to get tbh, you can order a package of meat and get some dry ice.

Quite the difference alright!

Does the extra cooling make it easier? From a layman's view, the idea of sub zero cooling is very easy, seeing as though there is so much more room for error(?). Not saying it is, but you know what I mean

That is pretty bat-shit crazy fast.

it's just how the semicondutor reacts to the temperature it takes less energy to flip transistors on lower temperature
