You reminded me of this from years ago. Same 'skill', different guy...

Did you ever get to the bottom of this @heretolearn ? I have the same problem but I'm running 3x Sapphire 280x. I believe the advice about VBE7 is the best - cards with older BIOS installed don't seem to have the same problems, as they run around 10C cooler than the same hardware with newer BIOS installed. Basically, any undervolt needs to come from the BIOS and not an application like trixx, or the cards throw a fit.

The other possibility is that the motherboard isn't delivering the right amount of power to the cards all of the time, MSI is not an expensive brand, they are a relatively young company in terms of their competition. I have been having the same issue as you, and my Asrock board is definitely a possible factor.

Does this ring true with anyone else lurking here?

Right. Except its 0.01176BTC/MH/ per DAY, not per SECOND as you have posted, but I'm guessing thats what you meant.

The UK has relaxed its tax rules on cryptos, so there has been a big confidence boost because of that. Its now easier for The City to trade with cryptos tax-free, so the big sales will be mostly from bankers moving profits around. The UK government just found a way to anonymously move money... so expect a lot of movement over the next few days.

Like the guy a few posts back, I joined hashcows about a week before the hack, and have lurked on this forum ever since then, registering today so I could LECTURE and THRUST my half-baked opinions upon you all (as seems to be the trend here), and I have to agree with everything that was said; Whenever payouts have been low (ignoring the general downtrend in alt-trading and BTC in general, its not anyone's job to explain economics to you), atriz and nearmiss have always explained why payouts were low, and if you have the patience to sift through all the whining and butthurt, you can find all those announcements, followed by hilarious sarcasm, abuse and drinking games from that Jedi fella, waaaaay back in this thread...

This last week, payouts have been great, the best I've seen here in a long time - I'm guessing thats from the sites hashrate slowly recovering, and a few good days for alts in general, I've moved all my miners back here and I'm hoping people who were here pre-hack start to regain the confidence that they had when they were praising the cows for paying back coins that were stolen back in December. I didn't lose anything because I'm not stupid enough to trust you with my electricity money, but I want to say thanks, well done and all that jazz to nearmiss and atriz for that one, I would DEFINITELY have been in the 'aaah fuck this' camp in your situation. Cut and run baby, cut and run! You clearly have better morals than I do. Oh and congrats on the baby nearmiss, I hope everything is going well for you, and the bloodbath that is childbirth hasn't put you off lovemaking forever...

Anyway...

Yes, the stats here suck ass. They always have done I think, but I don't mine to look at stats, I mine so I don't have to do what everyone else does; work 5 days to enjoy 2. I think some of the whiners on this page would do well to go and work a proper job and wake up to how easy the income is with mining coins. I used to work 80hours/week in a sweatbox of a kitchen to make this kind of money... "In my day we used to work 20 hours a day mining Cryptos in the fields... In the snow! In JUNE!...." Etc...

I've been getting about 0.013/MH/day, averaged out over 7 days. If you've only tested for a few hours or even a day, you can encounter a shitty few hours, or even just a slow trading day on the pool and is not very representative of actual payouts. Mine longer, do some maths. As for the guys having zero payouts, and level 9000 anger, I would fire a message off to atriz, and then give him a day or two to answer. Your experience of the site doesn't seem right to me.

I'm not going to be stupid enough to say 'stop whining', after all, i'm not your boss, and whining sometimes gets shit done. But please learn to read the posts before yours, even just a couple of pages back. Nobody is going to jump on you for not reading something that was said 3 weeks ago, but the least you can do is read the post above yours before posting, it would save an awful lot of scrolling through endless comments and angry replies, which in turn might even ya know, make a community or something...

Tl;dr  Hashcows seems to be back to normal. Patience is a virtue. Don't watch childbirth. Ever.
