[ANN][AUTO-SWITCH] Profit-switch auto-exchange pool: CleverMining.com

[TheGrolschFirm]

I gave this pool a chance and mined as long as I was not leasing out my rig. But the very high rejectrate is killing. Lowering my Intensity is not an option, because it will hurt my leasing income. This night CGwatcher restarted my miner twice because of extremely high rejects, 15% is about the lowest I had.

I read you are looking into a EU server. Hope that will lower the rejects for us Europeans. Lag and high-ping could be the culprit of getting higher rejects because a US miner is just a tad faster on those fast coins. 1-2 Hours ago I switched back to Wafflepool and my rejectrate is next to zero.

Keep up the good work, because I really like the site and the pool. When the rejects are under control (EU Server?) I will switch back in a heartbeat.

Pool is growing.
Are there plans for EU server ?

I just started testing this pool and I'm also interested in this. My reject % is a bit high right now (7-8%).

What does "Rejected untracked stratum share" mean?

they are counted in the first row (R:14848), but not in the GPU stats (R:1024).


this are my settings:

This thing has already been applied several times:

When cgminer sends shares via stratum, it does not send the share and then wait for the response as this might slow down the sending of other shares. This means that the response back from the pool is processed separately from the share submission (to make the most of a truly multithreaded environment). However there is never a guarantee that the responses come back in the same order you send them. So cgminer stores a copy of each share as it sends it to the server in its own local database of submitted shares. When it gets a response back about that share from the pool, it deletes the copy of that share. Now stratum is meant to be an uninterrupted connection to the pool, and if you lose that connection, it is assumed that your "session" is no longer valid. So if you send some shares and get disconnected before you get a response, cgminer has to assume that those shares have been lost - otherwise it may end up keeping copies of heaps of shares that it will never get a response to and wastes memory. If you manage to reconnect, sometimes the pool will actually tell you "oh by the way those shares are ok" - however cgminer has now thrown out the record of what those shares were and can only say that the pool said a share was accepted or rejected. Then cgminer just says it's an "untracked share"." (c) ckolivas

1. My rejection Rate is very High bRejected: 83.9 kH/s (13.8%)

2. I am running Sapphire R9 280X. The cgminer show avg 728 KH/s where as on the website 631.7 kH/s 24-hour Average.

3. As per the website  the  BTC per day is 0.01218 BTC/day per MH/s.Based on this calculation the BTC/day for 700 KH/s must be .008526. However i have only 0.00565835 BTC. i e 34% less than pool profitability.

Please advise

How long are you using the pool? Expect at least a day before drawing conclusions. it is true that the percentage of rejected is still high but the values ​​of profitability is not wrong!

I am running it for last 2 days. Why is my profitability 34% less than the pool and is there any settings to be done in CGminer

Search the thread.  This has already been asked, and addressed.

so they are shares that i actually lost? or they may be eventually accepted and i will see that number lowering?

Yes you can decrease Intensity in order to reduce rejected. I'm doing an experiment to see if this can help as it has been reported by Terk (admin) but I was not yet clear whether it actually works. Here you can find one sheet where I did a comparison (still in progress) between I = 20 and I = 17. https://docs.google.com/spreadsheets/d/1B-_UkIrGZYray8jb4K3Jnwx3JgweBHdaTCxgccgtFio/edit?usp=sharing

so they are shares that i actually lost? or they may be eventually accepted and i will see that number lowering?

From what I understand they should not affect your hashrate and are not counted among the rejected, the correct figure is in line GPU0.

[SirGeekalot]

i've dropped my intensity from 20 to 15 and the reject rate has dropped to zero. Unfortunately the Hash rate has dropped so much that the Profitability is now less than wafflepool with a 1% reject rate.

i'll adjust the Intensity until i can find a sweet spot and hopefully end up with a better profitability than Wafflepool.

The other advantage of a lower Hash rate is that the card temp is lower and as such i would guess my power consumption has dropped as well. i'm going to buy a WeMo plug today for some Wattage tracking.

Hey guys,

I just started to use your pool since several hours. Like many other peoples I am not happy with the high rejection rate. Is there a way to see my 24h rejected avarage? I did only find the rejected rate for the last hour. This would be helpful to optimize my miner configuration.

Thanks

i've had a few disconnects from the pool today too. i've had Cgminer up in an SSH terminal due to monitoring the Rejects and adjusting my intensity, i've seen it disconnect at least 4 times in the last hour.

im in the UK so perhaps this is a factor. please add me to the list of Euro users waiting for a local node.

I am not having disconnection problems and live in Italy, close enough to you!

1. My rejection Rate is very High bRejected: 83.9 kH/s (13.8%)

2. I am running Sapphire R9 280X. The cgminer show avg 728 KH/s where as on the website 631.7 kH/s 24-hour Average.

Please advise

Raw hashrate is 728 kh/s. Rejects are 13.8%. 728 kh/s * (1 - 0.138) = 628 kh/s effective. Pretty much exactly what you're seeing.
And I got the same BTC/MH yesterday. Seemed to be a lower-than-average profitability day.

To everyone struggling with very high rejects: You can tweak cgminer to use a lower intensity while still maintaining a high hashrate via the -g 2 parameter. But that will only help if your rejects are actually higher than the pool average. If it's already equal or lower than average, then you don't really need to worry about it because the reject rate is already factored in the profitability calculation, according to Terk.
