nice review sky

meh on the card. i guess the hydrocopper from evga or such will be the real deal.
also curious on how many will go and or take mobo/psu with them once the protection comes off
and or overvoltage occurs(user's faults :D)

Excellent work Sky. could you tell me how to properly interpret your scoring system? Would you give this card an 8 or 9 out of 10? Or like TPU a 7.

I hear people are blowing these things up by trying to increase the voltage to it.

I don't give arbitrary numbers to the conclusions. ;)

indeed, i looked at other reviews and if you push it it does seem to go up in smoke fairly easy.
would this keep folders away,perhaps?

I don't think this will keep folders away. They don't usually push excess voltages through their cards.

What do you make of This TPU comment from their reviewer W1zzard:
Quote:
As a first step, I increased the voltage from 0.938 V default to 1.000 V, maximum stable clock was 815 MHz - faster than GTX 580! Moving on, I tried 1.2 V to see how much could be gained here, at default clocks and with NVIDIA's power limiter enabled. I went to heat up the card and then *boom*, a sound like popcorn cracking, the system turned off and a burnt electronics smell started to fill up the room. Card dead! Even with NVIDIA power limiter enabled. Now the pretty looking, backlit GeForce logo was blinking helplessly and the fan did not spin, both indicate an error with the card's 12V supply.
After talking to several other reviewers, this does not seem to be an isolated case, and many of them have killed their cards with similar testing, which is far from being an extreme test.

According to NVIDIA this should not happen. In their official reviewer driver (which I used), the NVIDIA Power limit is designed to be active for all applications, not only Furmark.

FAQ about the OCP from NVIDIA:

Note on GeForce GTX 590 Overcurrent Protection and Overclocking

I still maintain that pushing things past the 1.1V mark is just asking for a failure.

Except that the GPU should be going up in flames before the other parts.

lol 90% of failures on VGA and mobo are the pwm

The PWM has to handle the excess juice BEFORE it reaches the GPU core. Remember, increasing the voltage significantly increases the stress on the other components through vastly increased power needs.
