Did I just killed my HD7950 with FurMark?

I bought my Sapphire 7950 Vapor-X last week, it worked fine until I attempt to overclock it.
I tried to overclock it to 1050 Core and 1500 Memory with 20% Power, 1.15mV. Then I ran FurMark and boom, screen freeze after 15sec of running. I had to reboot my computer, but there is no POST. My card just dead. My Asus mobo was giving 1 long 3 short beeps, which according to google it means bad video card.

Checked with my backup card 6850 and confirmed it wasn't mobo's problem.
I have also double checked the 2 x 8pin power cord were connected probably.

I read a lot FurMark can kill GPU story and I didn't expect it is really that easy to kill a card...I mean my overclock wasn't that high. And still it dies so easily.:( 

So is there anything I can do about it?

Sorry for bad english.


EDIT:
A little update. I have arranged to have my backup card to put in Primary slot and the dead card in secondary. I was able to get to windows and it reported error 43 for my 7950. GPU-Z gives this:

Well, it does sound dead... If you overclocked with only software adjustable settings, you can RMA the card. I think the default voltage is only 1.031 V, your voltage adjustment certainly wasn't too much (based on other overclocks around the net). I think there might have been a weakness (likely in the VRM circuit) that was just too marginal, and a slight OC might have done it.

Standard voltage should be 1.093V, if I remember. Chances are the card was faulty from the start, and the intensiveness from Furmark finally killed it. It probably would of died this week regardless.

Have you tried reinstalling the drivers?

Other than that, RMAing it should work, although Sapphire have a horrible RMA service. I would return it to the store you bought from.

Why would you run furmark? Next time you overclock run heaven extreme instead

I think that 15 seconds shouldn't be enough to kill a card. Sounds like it was about ready to fail.

In any case, avoid increasing the voltage when possible because it is a big HW killer.

You shouldn't just crank up the clocks by hundreds of MHz at a time. You should take it one small step at a time. That said, there's a good chance the overclock had nothing to do with it.

Fairly certain he only overclocked it by one hundred mhz, not a few hundred. One hundred is harmless, and he did up the voltage to compensate.

I think its good that its broken now, so you can return it back to the store, rather than it most likely breaking in the next three months from general wear and tear. GPU's are designed to be basically, if they are going to fail before the warranty expires, they'll fail in the first month of use.

It's still too drastic, and upping the voltage at the same time makes it more risky, not less.

Plus the Sapphire 7950 Vapor-X has a stock core clock of 850 MHz, so he increased it by 200 MHz.

He has the dual 8 pin 7950 Vapor-X which is the boost model. This has a boost clock of 950 Mhz.

Yeah but that's only a boost clock.
