HD 2900 XT too hot for liquid nitrogen :)

This is Kinda funny. I have never in my time as a bencher experienced anything this hot. Time to design a new pot

Maybe they should have used this

Amazing!!!!

[Nanometer]

That must weigh several tons lol.

[Shintai]

Now thats just plain scary....One this is sure..it wont have a coldbug then. Because it cant get cold! (kidding)

[theteamaqua]

wow !!! ..

btw with a good pot .. what kinda temp does the head of the pot get?? like -150C?? since Ln2 has temp of -210 to -196C

[WRC]

1.2 ghz core

[dinos22]

anyone else think that GFX card manufacturers are reaching the whole Intel Prescott era and will be looking to bypass the whole MHz race in favour of multiple cores

that would be interesting to see............dual core quad SLI or XF cards

They already made prescott look like an innocent mobile chip.

Also multiple cores? GPUs are basicly like multicores already. Unlike CPUs, GPUs have been parallel for ages. So you could almost say 1 pipe=1 core.

But yes, something like SLI/CF on a card could offset it some. Tho you use way more silicon and cost goes up in a rapid pace.

they are i know but you know what i'm getting at

1.2 Ghz wow!

[RAMMAN]

finally a situation where liquid helium could prove useful .

[Kunaak]

maybe time to design something that cools more then the core of the card.

[NightCrawler™]

That's just insane.... 1.2Ghz and instant tropic temperatures in your room...

[ahmad]

I imagine benching with this thing would waste a LOT of liquid nitrogen. Meaning, you would need litres and litres of this stuff.

[[XC] gomeler]

So what are we talking about, 350watts from the core alone? Current cascades are being tuned in the 250-300 watt range, guess it's time to bump up the requirements

[lawrywild]

What are the temps like with stock cooler? Must be like 100'C load or something?

[sladesurfer]

The card would namely have had managed even higher clock frequencies if it wouldn't have been for the heat; it was too hot! As mentioned, we were using a solid copper container filled with liquid nitrogen with a boiling point of -196°C and yet this wasn't enough to cool the R600 beast. At idle the copper container's temperature rose from -90°C to around -70°C which made it impossible to push the frequencies any further.

I guess the flame decals should have gave us a sign..

maybe they arent decals but burn marks

I have a 8800GTX that I have been runing over 1GHz core on for nature in 3DMark 01 and that was nothing compared to this. I think I used more then 10 liters in 50 mins (not kidding) on one 2900X.

A better designed pot would help, but then it needs to be a lot better.

[Johnny Bravo]

Hmmm perhaps the requirement for a constant feed system has finally occurred. Rather than pouring maybe a system where the LN2 is under some pressure and forced to flow through a block. That "proof of concept" that Chilly1 did springs to mind....http://www.xtremesystems.org/forums/...ad.php?t=42978

I bet you Legends cant wait for R650 @ 65nm.....

I think that accounts for almost everyone, legend or not

Crossfire and a Quad...who thinks 1K PSUs are overkill now???
