Which is these formula?
These formulae were posted by Kano in a KNC thread, they merely allow you to compute your hashrate properly:
https://bitcointalksearch.org/topic/m.3309728ElGabo has:
11213824*2^32/(25*3600+2.5*60)
5.3425410e+11
534 GH/s in accepted shares.
420356*2^32/(25*3600+2.5*60)
2.0026792e+10
20 GH/s in hardware errors for less than 5% HW
72191.*2^32/(25.*3600.+2.5*60)
3.4393565e+09
3.4 GH/s in rejected shares (538 GH/s full hashrate).
Which are outstanding values compared with what many people here, including me, have. Unfortunately it's hard to figure out what factors affect the real hashrates as most people do not post the source of their numbers and some others, like edgar, will prefer to cover the thread in flame instead of making some effort to search the threads, understand and cooperate.
My other question was if temperatures affect the output in your machine ElGabo, and if that affects HW (positively or negatively) but your HW is so low that your machine doesn't seem good to test this. Unless when the temperature is high (seeing that your screenshot shows very low temperatures) your hardware error rate goes much higher (which would be the opposite of what people including Phoenix and DigginDeep just above seem to be seeing). Then we could see if that VRM output correlates. Is that the case?
tunctioncloud: 0.97 is horrible for my machine and many others.
What I've seen about temps: Now it runs in about 22-23C at room, chips between 29,5-41,4C. I have 551-552Ghs, what you have seen on the picture. The HW rate is 3,4%.
I've tried to let it run a bit hotter, I got worse Ghs and worse HW. If I could make 17C room temp and was able to run the whole thing colder, I got 558GHs and less HW.
But then and interesting thing happened, when I've tried to cool it down better, 16C room temp and the chips between 20-28C after a while,when I was monitoring cgminer I saw x core disabled, x core disabled... and a whole chip died. LOL but for a while I got 663Ghs+....
So too moch overcool is not fine, but in my opinion too much heat also.
Unfortunetly I didn't care about VRM outputs until yesterday so I can't tell you exact numbers but now I take care and if I found something interesting I'll write it asap.
The only thing what I've seen about vrm-s is that mine outputs 0,718-0,763V (min-max). I've seen on other guys pictures 0,8 and above but I don't know they are on which firmware.
And yep, I'm runing on 0.96.
0.97 f... up for me. Better WU but more than 10% HW. And we know HW counts in WU here.... My avarage dropped down on the pool to 410....
