Should I be worried or not?

[Maxstl007]

How many rejected shares one got to be worried about? I'm using NBminer to mine Ethereum on nicehash pool so far I got 78 accepted shares and 9 rejected shares, should I be worried? Phoenix miner latest upgrade lower my hashrate that's why I switch to NBminer, seem more stable, I don't overclocked my gpu and it's temp is below 58°C

I'm new to mining but I've use Nicehash and Minerstat to mine some coins for days now, here is what I noticed, once my internet connection drops from 4G to H+ I will start seeing shares rejected in red color, it shows that your connection isn't stable, check your internet connection

If you don't overclock the gpu too high there is nothing to be worried about, shares getting rejected is very common if you overclock too high or if your internet connection sucks, NBminer isn't bad but phoenix miner still feels better, this is just my own judgement between the two mining softwares

I'll just complete the answer

Reject shares are mostly due to: bad internet connection (the location of pool counts) or too much overclock
If you are not using overclock like you said, don't need to worry

But 78 shares isn't good enough to measure, you have to give more hours, in my experience you need at least 1000 shares

Another tip, you can test another miners and compare the amount of shares in XX hours, there's some miners showing less hashrate, but giving more shares and less bad shares

I am using ethermine pool, i look at pool data, stale shares reflect internet connection quality-ISP and location (use asia if you are in asia, use eu if you are in europe). While Invalid shares can be a really very bad internet connection(getting timed out) or it can be hardware issue.

I found nbminer to be higher in hashrate for 1080ti but with occasinal invalid shares, while gminer has lower hash but with 0 invalid shares..i prefer gminer.

Look also at the pool not just your mining rig.

What's your network latency? If your value is above 300ms, then 10% of rejected shares is ok.
Overclocking of equipment may also be the reason for rejected shares.
But for a complete test, you need to look at the statistics for a few days.

That's lot of shares rejection, you should be having two or three shares rejected after 200 shares accepted if it's pool problem, I'm using Nicehash and NBminer is one of the miners for daggerhashimoto algorithm on nicehash, it's quit stable unlike what you said, pls check your internet connection and also change pool server, EU, US, etc

acceptable rejected shares 1-3% over that you should reconfig the miner or gpu clock setting, maybe to much memory overclock, temp under 70C still stable on many gpus

check vram temp, and the riser or something wrong with os/your internet most likely this wont happen but just check it anyway..move to different server pool just for testing

[Kvalentine]

Internet connection is the only thing that gives me shares rejected warning when mining Ethereum or other coins, check your internet connection or router very well, try to download stuff and see how speedy it is, you shouldn't have any problem with miner setup since you don't overclocked at all

Okay you are mining at nice hash.

They have  Servers

 In California
 In Europe

I think Brazil
and Japan.

So if you are like me in NJ, USA you are not close to any of them.

Some days point to the one in Europe works better than point to the one in California

Right now my nvidia 3090 rig is 9217 good and 74 bad pointed to California 124 to 1 ratio
and my 3 card amd asus rig is  4742 good and 51 bad pointed to California  92 to 1 ratio
and my 4 card mixed amd rig is 24365 good and 251 bad point to California. 97 to 1 ratio

So run you gear a few days and see if  you get closer to 90 good and 1 bad ratio

mine range from 92 to 1 up to 124 to 1

The evga 3090 is 2 days old and maybe is better since it is 1 card vs 3 or 4 cards
It is also on a better mobo with a better cpu a better eth jack
Maybe it is better due to being a nvidia vs an amd.  But all numbers above are good.

If you 78 - 9 continues to 7800-900 it would be 8.6 to 1. which is terrible.  But give it some time to see what it does when you are over 1000 or 2000 shares

I don't mine on nicehash twenty four seven but rejected shares are so limited, server is pointed to europe since I'm from Africa, seems to be the nearest server to me, sometimes I do 225 shares and 2 got rejected, I noticed that those rejections happened when my internet connection breaks or auto turn to 3G from 4G which is the fastest

I started with Nicehash and noted about 1-2% rejected shares (Sapphire Pulse 5700XT).  It was using PhoenixMiner.  I pinged all Ethermine servers (Asia, US, EU - I'm in Canada) and get about 23-25ms...very fast, 300Mbps internet.  I was having the AMD drivers crash every once in a while and narrowed it down to the memory temps.  I'm OC my memory to about 1860 MHz, the rest is 1250MHz, 750mv, 25-30% fan, 52C junction.  

I had forgotten about memory temp as Nicehash doesn't show you that, but looked in GPUz to see it hitting 94C at times.  I upped the fanspeed to 35% and no more crashes, and lower rejected shares, 86-88C memory.

When I switched to lolminer/Ethermine, I rarely have rejected shares and get much better efficiency (0.547 MH/s/W).  Lolminer also shows your running mem temp, which is now pretty consistent at 84C.

can you test your rig  with same settings on ethermine.org then show results?
