Well, you know you've arrived, then.

Looks like CL is down.  My rigs autoswitched to another pool.

+1...

Quick question, my one miner seems to occasionally lose Internet connection or switch to my fail over. It gets stuck however when reconnecting and just stops doing anything. Is there a setting I can add to restart the program if it doesn't do anything for a while?

Goes back by itself;)

Good thing that profits are now back up, I hope it increases even more!  

Thanks

CleverMining has definitely reduced rejects considerably but I still find it a major issue.  I have to dial back clockspeed on my cards (lowering my hash a little) and even then I routinely average 5 - 10%.  This is not something I`ve ever experienced mining elsewhere, whether mining currency or in another multipool.  I have just switched from CleverMining to another multipool to get some stats to make a decent compqarison, however for the moment I can`t make a decent comparison other than to say the earnings rates appear similar with the edge going to the new pool.

One thing that is clear however is that on CleverMining I am showing a reject rate in the region of 5% - 10% with no shortage of spikes considerably over this.  On a couple of other multipools I
On the subject of rejects at CleverMining, I took another look at my stats in an attempt to determine just how much of a factor the elevated reject rate on CleverMining is.  Firstly, I appreciate that hashrate does not equal earnings and that ultimately it is the bottom line, the actual returns, that determine successful mining.  Unfortunately at the moment I do not have extensive returns data to make a full comparison to CleverMining in terms of earnings however my experience so far is that I am certainly no worse off and I may be a fair bit better off elsewhere.

The main factor which impacts CleverMining so heavily is the extremely high reject rate experienced at CleverMining. I have mined for a number of months, both directly on pools supporting a wide variety of currencies and on other multipool pools.  I have mined on pools using servers in Europe, the USA, South America and Asia.  Through all of these pools located around the globe I have never experienced a rate anything close to the reported rate at CleverMining.  I`ve never even come close to half of that rate if truth be told.  So whilst BTC per day per Mh/s is how earnings are quantified, if that input is reduced by rejects in the region of 10% then that is a marked factor in profit calculation.

To put some nunmbers into all of this I run two rigs, one running 4 x R9280x Saphire Vapor-X and one running 2 x R9280x Asus DirectCU  II.  Under normal mining conditions I get 750kh/s out of each Vapor-X and 740 out of each Asus for a total hashrate of approximately 4480kh/s.  Before even getting to BTC earnings per Mh/s per day I looked at the Accepted Hashrate that the pools receive from me.  This is where I see a 10% difference in my inout hashrate and so inevitably in my ourput earnings.

Due to the increased reject rate on CleverMining I have been forced to reduce my GPU-Engine clockspeed otherwise rejects rates are considerably higher.  I should stress again that in all the mining I have done elsewhere I have never had to do this previously.  Even with this speed reduction I still see rejects of 5 - 10% although in fairness this figure has decreased and is certainly much better than it used to be.  Nontheless, decreasing overclocking?!?!?  Reducing speed?!?  What madness is this!?!?

Accepted hash on CleverMining is calculated as
4480 - 50kh/s (reduced clockspeed) - (reject rate 5 - 10% 220kh/s to 450kh/s - average 335kh/s) 335 = CleverMining Accepted Hashrate 4095

Accepted hash on an Alternate Multipool is calculated as
4480 - (reject rate under 1%) - 45kh/s = Alternate Multipool Accepted Hashrate 4435

Wilst the difference is not monumental, neither is it insignificant.  In very broad terms it is a 10% overhead not evident elsewhere.  Using an identical config, changing only addresses, I am unable to replicate this reject rate elsewhere despite trying a number of pools (both direct currency mining or other multipools).  Over the short period I have been collecting stats on the alternative pool there has been a marginally better performance than on Clevermining however as stated it would be unfair to attempt any form of categorisation at this stage with so little data available.

One HUGE PLUS for CleverMining which is worthy of mention is how accessible and approchable CleverMining is.  In the form of Terk, CleverMining has an easily accessible, eminently approachable internet presence providing updates and feedback on a daily basis.  Terk is regularly visible and responsive on IRC and often deals with potentially awkward questions with great tact and diplomacy.  For this he should be congratulated wholeheartedly.  Other pools would do well to note this critical facet of the operation and duplicate it.

Anyway to sum up, whilst rejects is not the be all and end all of mining and earnings is the critical measure of success, where earnings are measured in BTC per Mh/s per day, to lost a constant portion of that Mh/s per day is factor people are rightly considering.  Of course individual mileage may vary and as always it is down to the individual to make their own decisions.  However I just wanted to add my perspective to the mix.





 

Hi

for me it is the same....... i recognized a lot of rejects and stales (starting here on monday) and i tuned (cgminer.conf) my 3 rigs (2.5MH/s)
and it went down from nearly 10%-12% to about 6.5%-7%

This night i tuned the overclocking of my card 5% back (saves a little power/here in germany power is expensive)
i lost about 85kh/s and save about 65 Watt/h.
The rigs a running more stable and the temperature will be rising more and more at my side.

and what should i say:

16hours running:

4337 submitted shares
178 rejected (4,1%)
43 stale (1,%)

Now thats  about 5,1%  thats fair for a multipool and not more than on middlecoin or elsewhere.

So please please do not point to Terk (he is doing a great job) just try to solve the problem at your side first

Great to be here................and go on Terk, it is nice to see a pool that transparent like here...............

Hint : Try
 --expiry 1 --scan-time 1 queue 0

P.S.: It is not that exact because this night my rigs switch two times to middlecoin due to the ddos-attack here....so maybee the reject rate would be even better.........we will see
