Call me worried but, I think I have found a setting that gets me a decent hash rate with temps below 60c. 300 with the current set up that I have will yield 59 and 57 degrees on the blades but within the first hour or so I get 1 hardware error and over the course of a day and a half (36hours) I have 12 hardware errors. Now, I am powering this miner with a high quality 80 gold 650watt power supply.
first of all, are 12 hardware errors over the course of 36 hours ok for the miner? does that seem a bit high? I suppose the cooler I get the less likely the hardware errors will be produced. I am getting two new noctua nf-f12 fans, one at 3000rpm (push) and one at 2000rpm (pull) to replace my current setup as the wife has finally said the miner it too loud and producing too much heat.
I am asking about hardware errors again because I noticed that when I first set the miner to 300 it performed at just over 1Th/s and now it is working at just under 1Th/s. Do hardware errors effect hash rate?

The number of HW errors is not important. It's the percentage. HW errors are a GOOD thing for ASICs. It means your ASIC is being pushed to its limits for speed. Generally there is a tradeoff early on. Going from 0 to 1% HW errors results in a 5-15% increase in speed. and that takes about a hour to even out or become stable.
Future increases generally have smaller gains. Good ASIC firmware will automatically push the clocks up on ASICs to maximize the effective hash rate. but if it goes over a certain % that is bad, for the S5 i think the safe % is 0.388 or some thing like that . mine never go over 0.02 that's for days not mins or hours and i OC with a 750 gold psu or higher on all my S5, I'm not pushing OCing just saying even at 300 i would use a 750 or higher .
I would buy a 750 Watt psu gold . that gives you a lot of head room, but that's me. That may even be why the high temps it's not supplying enough power to keep it cool, when it needs it. I may be wrong . i can't say I all ways over kill on PSUs not to much but just enough that it's not a waste .
I thought about a higher PSU but I couldn't afford the higher psu and well, i didn't plan on overclocking the miner either so I just went with a supply that meet the miners needs, 4 VGA and at least 600 watts. So how to you calculate hardware errors in percentage? so I can make sure my miner does not go over a certain percentage.
