Ok, after ~10h, I tried 3 different settings with 3 different rigs:

• Rig #1

(these are the default settings for cgminer)
"queue" : "1",
"scan-time" : "30",
expiry" : "120",

Rejected shares:
4.8%

• Rig #2

"queue" : "5",
"scan-time" : "1",
expiry" : "1",

Rejected shares:
4.1%

• Rig #3

"queue" : "0",
"scan-time" : "1",
expiry" : "120",

Rejected shares:
1.8%


So, I am going to try the settings from rig #3 in all of my rigs and see if rejected shares drop.

Whats your ping? I have around 5-6% rejects with 60-70ms ping

I copied and pasted eu.clevermining.com, but the pings were going to nl.clevermining.com. Below are the results.

and link to stats and screenshot of cgminer would be nice too I bet most of your rejects are "rejcted untracked stratum share" which is not really reject for server, but cgminer takes it like that. Always check rejects per GPU

I tried to attach these last time, but there was no option to attach screenshots in the forum. Will start another run for about 2 to 3 hours and will post some links to screenshots. I usually get worried after 2 hours when my accepted shows up as under 80%.

PS: I just started a new run and I see all kinds of rejects. untracked stratum, job not found and duplicate.

Can someone post me the config for sgminer 4.1.0 using custom kernel.
I cannot get it to work via cgwatcher. I'm using sgminer 4.0.0 without any problems.

I mean on GPU your clocks? 

And how to put "setx GPU_MAX_ALLOC_PERCENT 100" & "setx GPU_USE_SYNC_OBJECTS 1" in config for cgwatcher?

I have warning that i don't have them.

I tried:

"GPU_MAX_ALLOC_PERCENT" : "100"
"GPU_USE_SYNC_OBJECTS" : "1"

But it doesn't start...

Hi Cooba13, you are right. Most of the rejected ones (19 out of 24) are "rejected untracked stratum share". Do you know what this is? Why do I have a lot of these and are these not actually rejected shares?

7970s are running @ 1090 core 1500 mem and you get 770KH/s? :-S

I am running a stock 7970 @ 1065 core 1800 mem and get 740KH/s and an Asus 7970 Direct CU II @ 1040 (higher clocks drop hash rate) and 1725 mem and get 714 KH/s :-S

You use the usual settings? -g 2, 8192, w 256, etc?

This is currently a known bug with the pool's interaction with CG/SGMiner.  Terk hasn't been able to smash this yet.... good news is that it's just a visual issue on CGMiner and SGMiner and does not really affect your work/earnings.  Check the site for the real reject rate or estimate it from the per GPU rate displayed in CGMiner.   Definitely don't go by the CGWatcher or CGRemote numbers, because they'll be based on the bogus reject rate shown in CGMiner.

What reject rate does the Clevermining site show for you?

[sapstar]

I have my rig running with clevermining for nearly 2 hours now. (I had to do a quick restart of cgminer once after the first 15 mins to enable logging into a file). I get around 22% reject in SGMiner. But out of the 122 rejects, now i know 88 are actually rejected. I can see in clevermining that my hash rate is captured as 2.7 Mh/s with 9.9% rejects (0.3 Mh/s) which seems quite accurate.

Now I need to findout how to reduce this 9.9% further.... which still is a lot of rejects compared to what I get with other pools. Any help appreciated.

Reduce the intensity on all your cards to 18. That will probably solve it.

Hi martynw2000, I will try reducing intensity, but this may actually solve the problem of higher rejects, but will decrease the Mh/s. Overall, there may not be any real gain for me. Ideally, i need to reduce the rejects without lowering intensity. I only get around 2.5% rejects with other coin switching pools.

It's about finding the sweet spot... lower intensity and play with other settings to see which gets you the highest WU value.  The lower rejects may outweigh the drop in overall hashrate, but it might not.  Mileage varies per miner.

Also, comparing reject rates between pools is always a bad comparison because they could be working on different coins.  Some coins have very low difficulty are are very "fast" so it will be impossible to avoid all rejects in those cases.  Clevermining has been aggressive in pursuing fast coins while other pools like Waffle avoid it.  Profit algorithms vary among the pools... only the final results at payout per day count.

Try:

scantime 5
expiry 10
queue 2

What card are you using r9 280x ? 7950 ?

try:

gpu-thread 2
xintensity 4
and thread concurrency 8193

Then just have an eye on your WU-Rate (after 1-2 hours)

and before starting sgminer again del *.bin before

[dragonmike]

or try this:

"scan-time": "1",
"expiry": "1",
"queue": "5",

worked very well for me on my 6x R9 280X rig.
Less than 1% rejected in the last few hours and WU rate is unchanged (over 90%).

My rig has 5 Sapphire 7950's. I have been having trouble tuning them. Currently they are running 975 core, 1250 mem clocks. I have under volted to 1.081. Never used xintensity before. the thread concurrency doesn't seem right for 7950??

Running with these settings now. Will let you know how I get on. I have tried the settings suggested in an earlier post, currently they are not producing good results for me .
