If Avalon are willing to stake their reputation on a public claim that their product provides 450mh/s with heroic cooling, and a third party verifies that using a few randomly chosen chips, I'll list them at 450mh/s.
The firmware they ship has a setting for 300 mh/s, so it's safe to include that speed in the chart.
Most miners are using a custom firmware that autoclocks. 350 mh/s is typically about where the autotuning settles for Avalon-supplied boards. I would consider that overclocking, and not appropriate to include in the chart.
To get the chips to go to 450, custom boards need to be used.
And i have some numbers to go with those from yesterday:
Slightly different air cooling setup therefore different temperatures with air cooling. (fan placement)
TL;DL : 450Mhz [9Ghash/s] - STABLE
But at the cost of 94Watts of power.
Air:
431 - 54, 48, 1.30V, 87W, stable
450 - 56, 48, 1.30V, 90W, HW Errors
450 - 57, 52, 1.34V, 94W, slightly increased error rate compared to what i normally call "stable" but close enough
Water:
450 - 54, 32, 1.34V, 94W, slightly less hw errors then with air
