I only know this because someone on another forum has a 5850 that isn't doing this and they were getting performance issues with it clocked at 157MHz (default for single display 2D), so they had to use ATT to manually set 2D clocks to 400MHz. He didn't report any heat increase with the clock bump but he's running on water so that's a given. I think the problem may have been fixed since then.
Anyhow although this is relatively less of a clock increase when compared to GTX 4xx, it shows that the increase is necessary, unfortunately.
Yeah I can see the need for an increase, but, logically, x2 the pixels = about 2x the clock, right? ATI goes from 157 --> 400, thats a little more than double, but ok. So, why does NV need to go from 50--> 405? More than 8 times the clock? I'm thinking its just a bios issue but then they would have fixed it by now if it was, so I donno.
