Difficulty settings dictate what level of difficulty the miner will accept and send to the pool.  Higher difficulty means higher rejects.  Diff 16 means harder hashes, but every hash counts as 16 shares.

Why does higher difficulty mean higher rejects? (Does it really?)

I think what he means is with the higher worker diff rate it just appears they have a higher rejection rate only because you need to take your accepted shares x worker diff then divide by your rejects to see what the rejected % is.

I never bothered to understand pool difficulty before.  When I started out with GPUs last year, the default suggested difficulty on my account/worker page had always been 1.  When I switched to ASIC last month, it stayed at 1 because I didn't know any better but in spite of this, BFGMiner indicated diff at 13.  Reading the recent posts on here prompted me to edit my worker just now and picked 17-32 GHash/s range.   My account/worker page now shows a suggested difficulty of 16 and BFGMiner diff is also 16.  What exactly happened here and what is the significance?  Is this the right/optimum setting?

Edit:  BFGMiner now shows diff went down to 10 (I'm confused).  BTW, since I made the changes, my Rejects went up form .08% to .21%, if that is even significant.

Difficulty settings dictate what level of difficulty the miner will accept and send to the pool.  Higher difficulty means higher rejects.  Diff 16 means harder hashes, but every hash counts as 16 shares.

Thanks for the explanation.

I have 3 GPU miners each with a single 7950 card. One of the cards suddenly is going extremely high in temperature reaching cutoff within a minute. Fan speed shows as if it's spinning at normal rate. This is my first GPU issue since I started mining a couple of months ago. Can anyone tell me what I should look for?

I have since turned it down too  750MHz GPU speed and temps are steady at 87C - and this thing is doing as much hash rate as a USB block erupter, which is a shame.

Any help is appreciated.

When you physically look at the fans - are they both spinning full speed?

I'll see it today when I'm at the site but thanks for the pointer, sensor could say one thing and fan could be off. Are they easy to find and replace?

Always wait a few days before looking at new difficulty projections, they're VERY inaccurate at first.  Right now BTC Guild was running at 150%+ luck for the last 18 hours.  That effectively puts the network speed projections at +175 TH/s just from BTC Guild.  If any other large pools had a similar lucky streak, the estimate is completely thrown off until that luck evens out.

I am pulling my BF from Slush's. Sad
From BitFury page I am hitting 36-39GH/s (running 24/7 obviously)
Lately there have been to many instances where BF is reporting 36Gh lets say ans Slush's is saying my reward is not what is should be.
My only temporary fix for this was to restart my miner every few hours or when I catch the rewards levels drifting off to where I know it's a problem somewhere.
(I am going to test a few days with Bitminter to see if any difference. The last 30min it's been 37 to 40Gh.)

Let the test begin.

Nothing wrong with using a utility as a currency exchange.
The higher cost is just the premium the utility is charging you to convert one currency to another.

Interesting.  I try to present a similar concept when I get asked about operating expenses (hardware, power bill, etc.) versus BTC mined.  For example: if mining one BTC ends up yielding a negative bottom line of -$100 (technically a loss) after all the operating expenses are applied, it can be argued that it is akin to buying one BTC at $100.  Therefore, based on the current BTC-USD average exchange rate of $138, it would then be an excellent buy.  It's all relative.

It turned out to be one of my high cfm fan controller going bad and stopped a case fan that was directly pushing air onto the card. This was also at night time so there was no air conditioning, hence temp jump. I removed the controller and all is back to normal but noisy as hell because this fan does 260cfm and sounds like a vacuum cleaner going.

In that case, you hace counted the coins' value twice.
Unless, of course, "if mining one BTC ends up yielding a negative bottom line of -$100" does mean you have counted costs and not subtracted the coins value yet.
But with a GPU, you definitely use way way more than 138$ on energy per coin you mine.

The "i convert currencies" explanation is perfectly fine, its just interesting that some trade a BTC for 300$ using the GPU, which is loud and hot in your room all the time, instead of buying from some guy at 138$ Smiley Not paying for energy could be one good reason, but there are stories where the miners found out these kind of deals can easily get cancelled when they start consuming way more than before all the time. The only explanation where i dont feel someone is really mis-calculating, is "its my hobby, i have no problem with my hobby costing money".

My example is just that, an example.  I didn't specifically say that GPUs would yield a -$100 loss per BTC.  Just in case you didn't get the gist of it, it's just a different way of looking at it (hence I stated, "It's all relative").  Why would it be counting the value of coins twice?  Please explain in detail.  What part of "after all the operating expenses are applied" makes it "counting the coin's value twice"?  I reiterate: if I ended up with a -$100 (loss) after all the expenses are subtracted, it stands that I have one BTC that cost me $100 (debit) which is actually worth $138 or so in the market.  Doesn't it mean that I'm still ahead $38 if I exchange that one BTC for $138?

Same here. I restarted the mining proxy to fix it.

 What part of "after all the operating expenses are applied" makes it "counting the coin's value twice"?  I reiterate: if I ended up with a -$100 (loss) after all the expenses are subtracted, it stands that I have one BTC that cost me $100 (debit) which is actually worth $138 or so in the market.

Expenses are subtracted from what amount?
If you subtracted from the coins value, like:
1 BTC: 138$
minus energy 200$
minus value decrease of hardware 38$
= -100$

than its not a coin which cost 100$ and is a good buy, its a coin which cost 238$ and is worth 138$, thus a bad buy which made you loose 100$.


If you just list all expenses and get 100$, thats not a 100$ loss, its 100$ costs, and if compared to the BTC price, you end up with a 38$ win.
If you did it that way, you calculated right, and i was just confused by the terms u used.
But the point of my initial post was to say that there is really no way for energy costs alone to not exceed the value of the mined coins by far.
So what i want to say: If you mine BTC with GPUs, even when not considering hardware costs, you will always end up "buying" BTC at a very very very expensive rate.
