It is possible to find out whether the card was overclocked, but as far as I know, only if the voltage(s) were increased.
The problem is that it isn't easy and it's time-consuming, so most people can successfully RMA their cards even after extreme O/C.

Also, you can't RMA oc'ed cards. Or you can, but you'll just end up paying shipping and not getting a new GPU in return because they test cards.
Overclocking and running non-stock voltages voids the warranty.

Saphhire just RMA'd my 5870 that I toasted. I didn't touch voltages but I certainly OC'd(980) the hell out of it. Best part is that it was only at 70c with .5amp fans blowin on the backs and front of the cards.
These "you can't rma an OC'd xxxx" is just a myth the manufacturers keep putting out because I doubt they CAN test the card. I'm sure it's some chinese guy who throws the pc part into a machine, the machine goes "it's busteded" and he go's ok! And sends a new one back.
Yes, TriXX
Hard to say what's wrong with the symptoms you describe without knowing more or having it in my hands. Take the card apart and visually inspect it closely. If there are no signs of damage then not much you can do unless you learn how to test individual components on the pcb. The fact that the card died so quick means even at stock it would have died within a short amount of time regardless. Poor quality on the manufactures part for that particular card, it happens to any though once in awhile. What means did you use to able extra voltage? TrixX?
You asked for the symptoms - it acted like the computer's PSU was dead, until I removed the 5830, then the computer booted normally. (the lights would flick on for a second, and every fan blade in the system turned about 1/4 turn and then it went dead again)
Basically I'm assuming the overcurrent protection was kicking in.
As to Jack of Diamonds - if running a card at 1.2v instead of 1.163v with 100% fan really was the sole cause of it dying in 2-3 weeks, then I submit to you that it would have died on me in a month or two at stock voltage. Also, it's not a "small increase in hashing rate" , the card was producing ~305 MH/s instead of 240-250

They can probably measure if OV was applied to the voltage regulator or GPU chip, nobody's going to be sending them working cards so they obv. have tools to inspect dead ones physically
I have some 58xx cards that run at 1.0xxx instead of 1.1xx, was basing it on that.
You based everything off assumption's or wrong information.

That's likely a trade secret to deter RMA fraud. Still, you can google warranties being denied even by just removing stock coolers, or fans (that should just be 3-pin connectors not transmitting data at all).

20% increase

Doesn't matter how high the fan speed is, you are driving 20% overcurrent to the GPU chip and overloading the VRM's. Not worth it for the small increase in hashing rate.
1.163v to 1.2v is not a 20% increase, more like 3%
2.) could VRM temps be how I killed my brand new Sapphire 5830? I was running at 1.2v with 100% fanspeed, and it died after two weeks

Reference, mcw60 block, stock plate w/80mm fan mounted in vrm location.
Crippled one already awaiting new smd capacitor for repair. Didn't have fan mounted on it. Considering piggy backing some capacitors for longevity.

That's a good idea, didn't really think about cooling the back side of the card to attack VRM heat. I am using 2 120mm fans ziptied to my Twin Turbo over the stock plate; waiting on some thermal tape to come by so I can replace the flakey stock stuff.
Live by the hash, die by the hash. You guys are asking for a fire.
1. Not all pcb's have vddc phase temp. sensor's. You can always buy an IR gun cheap.
2. Could be, best to visually inspect the board.
3. The red square in the picture I posted shows the missing smd capacitor. It was originally still there cracked along with the solder. Card still works at stock clocks with 1v.
What exactly is wrong with the 5830, symptoms?

Wow, that's quite impressive. What kernel were you using for that? If it wasn't the one that bitless updated several days ago, you can still get +3% performance out of it, and there is a newly optimized one that will be posted in a day or two that will add an additional 1%
Several questions:
1.) how do you check the VRM temp?
2.) could VRM temps be how I killed my brand new Sapphire 5830? I was running at 1.2v with 100% fanspeed, and it died after two weeks
3.) I noticed you said you were going to repair a broken 5850, how do you know what went wrong with it and what to replace? Do you think my 5830 could be fixed instead of trying to RMA it?
Thanks for beating the record I thought I set LOL

1.2375V! That's pretty serious.
How are you cooling your voltage regulators?
Is this a reference 5850?

make popcorn on the heatsink ?
Haha pretty much. I'm almost think I could craft a poop chute for the popcorn to fly out into a bowl
