7950 Sapphire dead after furmark? - Page 4

post #31 of 73
1.25V is a completely safe voltage for 7950. Most of the new ones come @ 1.25V by default, AMD is not stupid to overvolt their cards this high if it is dangerous, unless they want queues of people with dead cards knocking the doors of their AIB's departments.
Also 1150 MHz if your temps are low (less than 75 C) is a very safe OC, it is not even high like some people claim in this thread. That's only 100 MHz above 7970 GHz Edition.
It just appears you got a dud, nothing more, nothing less...

It just appears you got a dud, nothing more, nothing less...

+1 I completely agree with you. 1.25v is not as high. One of my 7950 Vapor x has a stock voltage of 1.25 V. it was just his card has been pushed to its limits. Heck even if you put 1.3 volts it wont hurt cause the card will just throttle it down.

Its just so happened that OP's card was dud like headless mentioned. And I know furmark doesnt really kill cards.

I used furmark to stress test whenever I received a newly card..... Thats the first thing I do, so if died, its only a day since I received. I start furmark, first stock setting, slowly and once I got Card's Max Limits, including power limit +20 and max 1300VDDC, I stress test it like 1 hour ^_^ even more sometimes... so far out of the three cards Ive done, 3 cards survive thumb.gif

What does OP and dud mean?
And that's why i was really putting a questionmark on why my card died so fast, within a few seconds.. I have no idea why. It runs and the fans are spinning, and it loads the windows 8 display, and stops there.. I'm sure i can RMA it, because there are no physical damage etc etc. But i just haven't really got an explantion of why it just died. It's not more than 2 months old aswell.

OP basically means thread starter, in this case you. Dud means bad/defective, in this case your card was a dud (bad unit). If your card has a button or switch on it to reset the BIOS I advise resetting the BIOS before you send it back.

Theres a button on the card with an "S" on it. I've pressed it a couple of times since i had no idea of what it really was/did. When i pressed that button, i could get into windows etc. Does that mean i resetted it? or is there anything else i had to do?

Oh well, sometimes it didnt work, so i had to restart and push again. Had to do that a couple of times before it could boot on that 'boost bios'. But yes i did manage to boot, and it did light up. Is it resetted then, or?

I've had both my 7950's past 90 C on the core in games, same for the VRM. I actually think I hit 100 C on the VRM once, but not sure. You know you're pushing it when your room starts smelling like hot electronics... Anyway, no problems for me so far, my cards usually top out around 80 C in games after I fixed my side intake.

Gigabyte's stock voltage is 1.2 V on these cards BTW.

i dont know what dew means about resetting.... can you confirm that you can boot up with the boost bios switch on or lighted? because if you can you need to only reflash your non boost bios... that happens to me...

and that only means card is fine..its only non boost vbios is corrupted... can somebody confirm this? i am no expert...
