Geforce GTX 590 brinner i SweClockers testlabb – drivrutin boven i dramat

It appears that some of the first NVIDIA GeForce GTX 590 video cards to ship come with Forceware 267.52 drivers and they don't prevent the card from overheating when overclocked and overvolting

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

Overclocking the ASUS GeForce GTX590 with more voltage on the GPU proved to be rather tricky. When we first added more voltage to the card and overclocked it up to 743MHz on the core with 1.1V our 3DMark Vantage score dropped like a rock from ~X21780 to ~X1800. The GeForce GTX590 was using too much power and was being throttled. We lowered the voltage down to 1.01V, turned the fan up to 95% (the highest SmartDoctor would allow) and put some cooling fans in the room and once we did that we were able to get some runs completed at 753MHz on Vantage with a score of X22243. This still has some throttling going on, though, as the scaling isn't like what it was prior to the voltage increase to get past the 690MHz wall we hit with default voltages

We noticed that the card would run short benchmarks like the game test in AvP with minimal issues when overclocked, but longer tests where the card got hotter or drew more power didn't do too hot. You wouldn't think overclocking would increase the power draw that much, but we were seeing an additional 109W at the wall when overclocked with a voltage increase on the core. With our system running at 803MHz we saw 591W flash on the power meter during the same benchmark, so it gets power hungry when you crank up the voltages. This video card has the ability to run at over 800MHz, but it is not possible with the NVIDIA reference cooling solution without losing performance. We tried everything and even got the room temperature down to 65F on an open test bench with fans on everything
