ASUS Radeon HD 5870 Overclocks to 1525 MHz
The ASUS EAH5870 MATRIX Radeon HD 5870 card saw an 70-percent increase in core clock speed.
This forum post over on Xtreme Systems claims that community members Elmor and Kinc managed to overclock an ASUS EAH5870 MATRIX Radeon HD 5870 card (2GB) to a crazy-fast core speed of 1525 MHz (core), making a 70-percent speed jump over the default core speed of 894 MHz (850 MHz for the reference card).
The memory overclock wasn't quite as spectacular, cranked up to 1300 MHz, showing a rather pleasant 8.3-percent increase. The overall process remained quite stable at the 1500 MHz point, proven with the use of 3DMark Vantage and scoring P29342 points at the performance reset.
The duo kept the overclocked card cool by using liquid-nitrogen evaporators. The bench also featured an Intel Core i7 980X Extreme Edition six-core processor clocked at 4492.9 MHz, an ASUS Rampage III Extreme motherboard, 6GB of Corsair Dominator GTX DDR3 memory, and an Antec 1200W power supply.
The forum post displays all the validating credentials such as the bench, 3DMark Vantage screens, and CPU-Z screens. "Around 1525-1550/1325-1350 should be possible with more time on this one," the post claimed.

Nice OC, but with LN2, I'm not really surprised. Now if somehow they did this on air, I'd be shocked!
I wonder if you could build large passive heat-sinks to replace the stock fan. I you had them sticking out into the empty space in your case it should cool better right? I wonder if you could buy them or cut some out of aluminum.
Interesting. Still wish there was headroom with air.
I was impressed by this initially. Then I realized it had to be using LN2. At which point I decided it wasn't very exciting.
Meh the Phenom II goes up to 6ghz on liquid helium, but sucks against intel when overclocked on air. So forgive me if I don't get excited for something that 99.999% of people won't be doing and therefore doesn't matter.
Why do I get the feeling that everyone over at Nvidia just
Why do I get the feeling that everyone over at Nvidia just a little?
I thought I smelled something......
I bet it probably still uses less power than a fermi card.

The problem is that there is much more material between the heat and 'gone'. Think of this passive heatsink as a broad river with almost no slope, the active as a narrower one with more slope and a shorter distance. The second will get rid of its water (heat) faster than the first.

If a large passive block wouldn't work (sorry stupid idea), could you have a ducted series of thin fins extend from the processor and have a dedicated 120 mm or so fan blow over them to the outside? with the greater surface area and a powerful fan I would think more heat could be removed.
In other news, nVidia's lab caught fire moments ago. The flames where quickly dispatched by firemen, and no one was injured.
Questioned about the possible cause, one nVidia employer stated that "It all happened very fast. One moment we were trying to push our cards to the limit, then suddenly everything was filled with flames."
The nVidia president said that such an accident was expected.
1525?!? DANG!! Where are them Crysis benches?
@_@
Holy cow. I have seen some impressive overclocks in my time, but that is insane. I want benchmarks!

Maybe in an antec skeleton or Xclio Wind-tunnel with all the fans cranked.... or if you put your case outside in the winter- that might work too.
I thought it was done by air. Anyway, still impressive though.

"We designed them to catch on fire and burn down our labs."
So... When can I buy this thing?
I am 100% sure that in the picture there's a Corsair PSU (you can see the logo shape in the usual position), probably the TX850 judging by the color... where's the Antec 1200???
Asus products has one of the best performance however it has rarely put an effort into its heat management, allowing its product to have less than decent temp.
For normal users they r not gonna use LN2, so overclocking wise it will not go much higher than others due to heat constraints.

It's a TX850 or TX950 by corsair yes. I can't quite read the number in the picture, but only those two have this yellow color.
Holy freakin' crap that's awesome!
LOL, sure buddy. Wait till they start overclocking fermi's with LN2. I'll put my gtx 480 against a 5870 any day.
hopefully it doesn't go nuclear at that point
The psu used is not a Corsair look at the right, the Corsair is not plugged at all to the motherboard.
that's what i've seen with the card... stable core clocks, but memory doesn't really go anywhere...

That's the funniest thing I've seen all day.
"We designed them to catch on fire and burn down our labs."
THAT was the funniest thing I've seen all day. Last post was a misquote.
I want to see LN2 with Fermi...
Maybe then we can see load temps below 90 degC
But seriously though, I'm thinking of swapping my ASUS 5850 for one of these 5870 'Matrices'.
That'll free up my 5850 for my SG05 / i5 750 system too.
So far, even my ASUS 5850 reference card has been fun to tweak, so the Matrix looks like the card for me.
