I guess you tried to restart ... check cables etc.
If it's only one rig that give you issues, you might try fresh cgminer 3.7.2 in a new folder.

I've tried restarting, all cables are fine, tried cgminer 3.7.2 and 3.3.1, it has to be server side

there is no reason for this to be on one rig only... try to disable half of the cards and see what happens
BTW in cgminer you can see which card gives you the most rejects... is it one or all?

All 4 on that rig. I'm at 19% rejects now... also, it seems to be fine at night, I'll check it randomly and my hashrate is at or near 6.5+ mh/s, but then throughout the day, it drops.

can you post a screenshot of cgminer?
do you monitor your hashrate at middlecoin or on the rigs?

I will when I get home from work. And I monitor my WU and my hashrate on middlecoin. My hashrate on cgminer is stable for all my cards.

Hey guys, is my rejects rate normal?

Can someone share the step by step instructions for compiling sgminer (not cgminer)? Please don't point to binaries, I simply need the instructions. I ran through one compile and need to make sure I did so correctly as I am seeing some errors.

Very low rejects, good for you! Which server do you use? I guess you have faster GPUs - 290? 7950? My reject rates hover around 4-5%, mix of 7770s, 7850s and 270.

Sweet :]  Probably a combination of fast cards and low latency connection. I'm getting 2.5-3% rejects on USEast (7950/7970/280x/290) so far vs 5-6% on USWest, however, you are doing way better than that haha

Good question. Both EU and US servers at the same time with balance options. I think I'll add all servers and more optimized settings later, maybe even a BIOS flash.

whoa...

First of all, since it's my first time posting (long time lurker) allow me to say hi to everyone. It's great to read all the talk, advice and even arguments around here. I've been mining on Middlecoin since last month and I've gotta say, it's made me get into altcoin mining more seriously, to the point of purchasing a new GPU to improve my hashrate and earnings. I'm still adjusting and testing setups, and basically trying to figure out if I should keep mining, invest more money and resources or just quit altogether.

Up until today I was under the impression I could really pull it off, but since the diff increase today I'm having serious doubts. I'm making around 530Kh/s (7850+5770) and I've gone from 0.8-0.9 shares per minute and 30% efficiency (CGWatcher stats) to only 0.3 spm /14% efficiency today. I do NOT mine 24/7, just around 12-15 hrs a day, so its obvious my balance will drop considerably.

My question to you all, specially to those of you who have low hashpower (I feel kinda like I'm the only small fry posting here :/ ) is the following: Should I keep mining here? I love Middlecoin, and frankly, I ain't had any 'bad experiences' with my payouts, nor with balance or shares. Middlecoin just suits my needs. I point my Miner to middlecoin.com and get BTC, no multiple wallets, cryptocurrencies and trading. However, power bill isn't getting any cheaper, but my hashrate isn't enough anymore.

Is any of you having the same thoughts? Do you think ivesting in a couple of 280x/7950 would make it any different right now?

That looks like a great reject rate, but how much time passed since you started cgminer till you got those stats? (NVM, I didn't see the timestamp the first time i read) I'm myself between 1 and 3% Reject usually

No, its not obvious. The higher difficulty means more variability, but the long-term payout should be EXACTLY the same.

There is no such thing as "enough" hashpower. 

Do you think ivesting in a couple of 280x/7950 would make it any different right now?

Yes, you will double your earnings by adding one 7950. But again, pool difficulty has no effect on payout. ROI on a 7950 is just a couple months right now.

Add to this that middlecoin registers your hashrate as long as it's above 1kh/s, but even below your shares are still recorded. It might take a (EXTREMELY LONG) while to cash out 0.001 BTC with such hashrates but you can always compare profitability by looking at other miners and their revenue/power.

[dgross0818]

Profitability of mining scrypt has dropped considerably from where it was in early to mid December, however, as long as you have cheap (or free) power, you'll probably make ROI within a few months.

Of course, with the variability of the markets, profit changes day by day, however, in my opinion, investing in hardware still isn't a bad deal, as the components still have a value in their utility to others (for gaming/rendering/etc) even IF scrypt mining was no longer profitable.

That said, know that the price of the hardware would probably drop by 35-50% or so if that were to occur... 7950's were going for around $180-200 as recent as early November... and 280x's are only supposed to retail for $300 new (not counting ones with custom cooling solutions)

Just remember to set aside money for your power bill if you do invest in hardware :p Nothing like waking up and realizing (even at $0.085 per KW/h) you owe $450 haha

Still at work, so nothing has changed on my rigs, yet now my hashrate is above 6.1mh/s again with 3% rejects. Has to be server side...

Thanks for your answers, my doubts are almost gone now I really didn't know the diff increase didn't affect share subsmission (yeah... I'm *that* dense :/ ) I'll check my logs to see if there was something wrong with my cards, or my connection.

I'm back to 0.7 spm as of now, and 28% efficiency, and no rejects whatsoever for the last hour.

I'm sure the guy with 1Gh/s+ also thinks there's no such thing as enough hashpower

Good to know, I was eyeing a couple of preowned 7950 for 170 Euros/each (Retail price is around 230 Eur. here) but, man... power just went up 2.3% this year (Electric companies wanted to raise a whole 11%, hah!) so I'm gonna wait until february just in case

Or you finally realize that there's a certain element of "luck" to mining.

the rigs and the server are not the only variables in play. network connection also has some part in it.
you don't really have to change anything for the things to go wrong and yes it might be server side, but when you see too many rejects you should also check other users' rejects to see if there is a server problem. if you don't find anybody in similar situation - it most likely is not server side issue
for example a couple of days a go one of my 280x was constantly shutting down when it get's to it's regular kh... no matter what i do through teamviewer... at the end there was an issue with one of the 12V cables and the card was not getting enough power and it worked for a month without me changing anything

While I don't think luck alone would contribute to such a dramatic change, I think most of us notice quite a bit more variability in our hashrates since going to 1024 diff

Earlier today I was "mining" above my actual hash rate through "getting lucky", however, now I'm under where I should be.  All my cards are still running fine and no network issues... just haven't gotten as many accepted shares in the past few hours.

If you average it out over the course of a day or longer, you should be very close to what your WU's are... if that's not the case then it's a hardware, network, or server issue
