This is a good spot to start.  When you express things like "include VARDIFF and this pool will be better" then you are expressing a fundamental misunderstanding of how mining works.  Your hashes are not part of some global race to a solution, they are each individually capable of winning the lottery (aka share/block reward).  

Higher difficulty causes more variances, but if you are mining for more than a day or two, everything evens out and some days you will have lucky days where you get more shares than you should have with any given hashrate.  This stays the same whether the difficulty is 1 or 10,000.

Oh, I use r9 280x, so all my gpu's are set to -I 13. Terk, and other people, said that if you use I-20 normally maybe it is better to lower the intensity a little bit(one or two points). I can not comment over this because I didn't need to do it.

According to cgminer readme -queue is the number of work that your workers have downloaded to the server and didn't just started, hence the name queue.I had previously set it to 1 , because 0 didnt make sense to me, but a guy who appeared very knowledge on the matter said to put it to 0 a few pages back. I did and it certainly isnt hampering the performance, I hope it is helping but I cant really be sure because tweaking can be a tiresome procedure so I didnt follow a cientific approach to it: Change something, leave it running for X hours, see the result, start again.

People that have a absurd ammount of reject:

Something is wrong with your config , internet or something else.I live in Brazil, so I think it would be fair to say I have , in average, the same ping from you guys in EU and I dont get absurd ammounts of reject.Maybe I cant get 100% perfect tweaked config but I have been averaging 5% rejects in a 24 hour window for some time  and my reject are in 70-80% of the time lower than the pool's,as seen on the stats page. Just for a comparison my pingtest to a server from california averages 200 ms

I saw this fight before in MC thread, In theory it should be equal, But if you take reject shares as waste of hashrate, it makes difference.

-I 13 --queue 0 -g 2 -w 256 --gpu-powertune 20 --thread-concurrency 11200 --temp-target 75 --temp-overheat 95 --temp-cutoff 97 --gpu-fan 40-100 --auto-fan --gpu-engine 1020 --gpu-memclock 1500 -o stratum+tcp://us.clevermining.com:3333 --scrypt -u 18MEFUcfHiQdEDMe3GKfW16FTAFhX6WhBA -p x --failover-only -o stratum+tcp://middlecoin.com:3333 --scrypt -u 1MbyxkJGxQzpzPCWa6dXnQYJvtNei1h9ny -p x

This is a exact copy of thje config on my r9 280x windforce(gigabyte), my shappire works on a similar config but I have a his r9 280x that need --cpu-engine 920 to give an average decent hashrate(650).

p.s.: dont forge the max_gpu_aloc and the other things

You should be getting 730kh/s out of that 280x.

Try --thread-concurrency 8921  --gpu-engine 1049

Is there a way i can see my rejected percentage on the website, witout scrolling until i find my address?
A Search function?

On GUIminer-script, I can't see the difference between stale and rejected?
And the Stale shares pays out, correct?

Sorry for all the noob questions! 

You can find the search here:

Hopefully Terk can answer this, or someone else.

So I have invested in the new gridseed dualminers, they are the first scrypt asics on the market and in the wild.  I am just curious if all scrypt coins are the same as far as memory requirements, and if any scrypt coins pose a problem for me mining on Clevermine?  I know we don't have a list of the coins that the site mines so there is no way for me to tell if there will be any conflicts with my new mining hardware.  If anyone has any input, or can tell me if they suspect that I will have conflicts sending my hashing power towards this pool that would be appreciated.  As far as I am aware there should be no difference between the scrypt coins, but I know that some newer coins are asic resistant and my hardware would not work with them such as Vertcoin with the adaptive-N-factor.  

Thanks in advance,
Poopy
