[ANN][Pool][Profit-Switch][Optional Auto-Exchange per Coin][Vardiff] ~ Hashcows

I heard about this recently and decided to give it a try. The profitability charts looked really nice, for example. Anyway, here's my 24-hour review of Hash Cows vs. Litecoin. I'm going to keep it going for another day, but so far things aren't looking all that good compared to other mining options.

"every time they switch coins, my miners all seem to swap over to my secondary pool for several minutes"

did you use cgminer <= 3.5.0?
if not, you should redo your tests.

We had a bad day that day down on the farm. Do a longer test pl

Why is that?

Why is that?

because >3.5.0 has a delay of 5 minutes when a pools fails, thus you loose a lot of mining on hashcows, due to coin switches.
earlier versions have a much shorter delay, so are more suited to multicoin pool mining.

Ah ok. Two questions though:

1) Is there maybe a config switch in >3.5.0 to manually set a shorter delay? If yes, would 1 minute be a safe number to set this to?

2) Are you not sacrificing some other possible benefits when not using the latest GPU-scrypt cgminer (3.7.2)?

Thanks!

1) not that I know of: but you could modify the source; I don't think it's worth because of 2)
2) i heard some people use 3.3.2 o similar because of supposedly better performance; I myself have used 3.7.2 on a conventional pool and seen no difference with earlier versions.

a) A couple of hours of down time will effect results.
b) Some coin is always waiting to mature and be exchanged (you'll be getting credits for about 3 days).
c) Mining involves variance, so any results of a comparison test that is less than 2 weeks, run side by side, is meaningless (imo).

Since last night I quite often gets disconnected and it says failed to connect, after a while it says waiting for work from pool and eventually it resumes, is this normal considering the problems as of late or is something up with my rig?

I also get this as well, hashcow server are not responding, happens on all 10 rigs with various version of cgminer 3.1.0 > 3.7.2

I think the problem is overload on the server with all the new hash-rate the site have had the last cobble of days. So i HOPE that the new server will sort out the problem by taking 50% of the load.

[CoinBuzz]

Could you add Bitbar (BTB) to the pool please ?

It obviously happens only when pool is switching to another coin, and it gives sense. I am still using CGminer 2.11.4 (best so far - I never mention any change with newer versions, it only get worse) and disconects lasts only few seconds.

hi, I am pretty new to mining, just set up my rig today, all seem to go good, but I am getting a lot of Rejected Shared in 10-20% range mining coins like DGC and, wanted to check if this is expected or something is wrong with my rig.

not so obvious since it started happening yesterday evening, never before and it lasts for minutes at a time, not seconds

Getting a massive rejected share rate as well. Currently over 20%

edit - it's dropped below 5% now /wipesforehead

Anything over 3.3.1 and cgminer starts to get worse for scrypt.  You'll get the best hash rate and least amount of disconnection time from it.

I must say I can tell you took the time to write-up a good review, too bad it didn't sound too good for us!

In response, you have been mining here for two days which really isn't an accurate or fair assessment of the pool. We are having issues with coin switches (which you stated in the review) which is causing our stratum to get stuck and even in cases go down for 3 hours per day. We are aware of this issue and hopefully will have some good news on it in the immediate future. Like others have said one way to put a patch on the problem is to download a previous version of CgMiner which doesn't have the 5 minute failover. If you do leave and you are not satisfied, I invite you to come back when things are fixed up and give us a longer test period.

The pool has been pretty stable for the last 2 months and of course with everything in life there will be small hiccups, I know everything seems bleak right now as we have had two days of issues though we can assure you better days are ahead.

[coyote]

I hope I am not tempting fate here but things seem to be settling down again after a couple of very bumpy days.

As far as I can tell the main outstanding issue is disconnects and (decreasingly) occasional stratum failures associated with coin changes.

Whilst a bit worrying I see the problem with the stats and payout estimations are secondary to making sure the mining equipment stays fully occupied.

I'm sure everyone here would appreciate a quick update of what you guys (Atriz & nearmiss) believe to be the outstanding issues and what your priorities are.

Keep up the good work guys - I really appreciate what you have done & are trying to do here.

Ok a few updates on my side. Since yesterday I took out the backup pool. Yes I do lose connection when coins switch however it's brief..~30 seconds or so. Not a big deal. Since I can monitor my home rig via remote desktop I'm not really worried about the pool being down for a long period of time. It's more problematic during the night. If the pool really goes down..I will lose some time. Anyway

In terms of profitability.. according to litecoin calculator if i mine LTC at current difficulty and at 950kh I will be earning 0.31 coins per day. At an exchange rate of ~ 0.035 BTC/LTC... that comes out to be 0.01085 BTC / day. Take out some conversion/withdrawal fees..and I'll probably be left with 0.01..or maybe 0.009xx. Not to mention the time spent to withdraw coins from a pool, deposit them in xchange website, withdraw BTC.
Note: The LTC difficulty recently increased..so maybe my LTC profit calculations are a little lower..however at the previous difficulty I was mining 0.35 coins/day which is the equivalent of 0.012 BTC. However since we all care about the future...LTC difficulty is only gonna go up. Value..no idea.



Now, I've been mining on hashcows since Sunday (Dec . However Dec 11-12 I had a failover to LTC so basically for every coin switch i would mine 5 minutes on my backup LTC. here are my results after all fees.  NET results:

0.00586563
0.01470448
0.00674348
0.01443159
0.00909768

Total: 0.05084 over a total of 5.5 days. On top of this my backup pool generated: 0.162 LTC (0.005 BTC). not to mention the fact that hashcows and exchange websites had problems over the past few days. So overall I would say hashcows is doing pretty well. So far i get the results im expecting. Sure, payouts are not cosntant on a daily basis..so that's why I suggest you mine for a few days before complaining.

For the time being I'm sticking with hashcows. equal or slightly smaller profits but with less of a headache.

Keep it up guys !

Giving an average of BTC0.0134 per day

This is on 800ish Kh/s spread over 3 cards & 3 virtualised CPU machines (I know!)

Yesterday was made worse by me spending some time tuning my card performances & I crashed one of the machines with 400Kh/s for about 4 hours.
