On a unrelated note.  What just happened in the blocks?  99.9% for 10 hours then one solved in minutes using 44Thps?  Glitch in the matrix?

A 10 hour block can happen, that's just bad luck. The other block took just 1 second to complete. In such extreme cases the hashrate estimation gets way off from reality.

I get the variance, that happens.  What puzzled me was the steady 5.5GHps for every block but the one that only took a few seconds.  It was right before the 10 hour one, and it's (the shortly solved one) rate was 44Terahashes vs the normal 5.5gigahashes..  That's the glitch I was talking about.   It's just a strange thing to see.  Basically it was just a glitch in the matrix in the end.  I wonder what the odds are of solving a block in 1 second at this difficulty.

Hi, I have a Radeon HD 6850 and I tend to get around 190 Mhps, which is O.K. for me.  My problem is that even with my GPU fan at 100%, leaving the BitMinter client on for more than 1 minute will skyrocket my GPU's temp to exceeding 80C.

Is there any way that I can slow down/limit the mining to make it work less, and reduce the heat produced?

(Apologies for possible newbie-questions, still new to bitcoin mining)

Cheers Tongue

I am running an ATI 6670 and an ATI 4850.  Both are running with a monitor attached to each.  However, unless one of the cards is disabled in device manager in the control panel, none of the bitcoin miners will open.  They just crash.  Again, it instantly works when one card is disabled.

Sounds like a driver issue. Try cleaning out the drivers and reinstalling them.

Is this really true? I just started and am wondering if I am actually getting around 200Ghps.
I'm using a GeForce GT 650M with BitMinter 1.3.2

Also, is there a way to optimize the work group size and work interval?

All hashrates displayed on the web server are estimates. When doing an estimate for hashrate over a period of 1 second then the estimate will be off. Therefore the 1 second block's hashrate is wrong.

Is this really true? I just started and am wondering if I am actually getting around 200Ghps.

This is a bug with Apple OpenCL. Sometimes it breaks. It shows crazy high hashrate and never finds any results. Reboot your Mac and things will be back to normal.

Also, is there a way to optimize the work group size and work interval?

You just have to try them and see. 20 ms work interval gives good performance. Set it lower if you want smoother desktop, it may drop performance a little.

I need help understanding the payout transaction fees. Are they a fixed percentage of earnings paid out regardless of how often or is it a fixed amount per transaction? Is there any fee at all charged to the recipients or is the fee paid by the pool? I know there are several recipients of each payout but how does that work transaction fee wise?

Basically I prefer to be paid more often but I can set it to pay out less frequently if it's going to cost me more in fees.

VTC, the new BTC. Sorry ASIC miners.

BitMinter to take 1% fee - still most profitable of top 10 pools

BitMinter has been zero fee for a long time. Unfortunately this is not a sustainable way to run a pool because most miners set their donation to 0%.

We will be moving to a 1% fee on saturday 20th of april.

We are still the most profitable of the big pools, due to low fee, paying out namecoins (6% extra income), paying out income from transaction fees (1% to 2% extra income) and being safe from pool hopping.

What happens on the 20th of april:
- 1% mining fee takes effect (BTC and NMC)
- Prepay perk cost reduced to 1.5% (from 2%)
- Users with prepay on will have their donation reduced by 0.5%. Set it back up afterwards if you like.
- New users will have a 1.5% default donation (rather than 2%)

There will also be more perks coming, but I can't promise any timeframe on that.

Hi DrHaribo.
Could you elaborate a bit more on the last point "New users will have a 1.5% default donation (rather than 2%)". Does this mean that it's cheaper for me to wait until the 20th before joining BitMinter? Smiley

I've been mining with PPS pools for a few months but due to recent downtimes, and more personal dedication to mining, I figured I'd try a PPLNS pool. 

With PPS pools I've always been able to see a steady "24 earnings" metric.   With Bitminter, in my first 24 hours, I'm looking at less than half of the normal bitcoin payout I'd see.  The worker estimates are all over the map whenever I look at the page, varying as much as 50% down from the near-constant value cgminer is reporting, which is stressing me out.   I can't tell if the estimates on the worker page are bad or if it's actually something wrong with work submission.   cgminer has reported a constant rate the whole time, with <0.1% rejects and no HW errors.

What's a reasonable timeframe in a PPLNS scheme to compare to PPS earnings?  I'm a little nervous to continue here if my stats keep trending like this.

No what he means is that currently the donation for perks is 2%.  After the change on the 20th it will drop to 1.5%.  So you can join now without fear.  After the 20th the flat fee will be 1%, and if you want to activate perks you need to bump it up to 1.5%.
Basically right now you could set no fees at all in bitminter, but if you want the perks (Prepay, etc) you donate 2%.  After the 20th there's a 1% fee no matter what, but if you want the perks you bump it to 1.5%.   Current new users are auto set at 2%, but after the 20th they will auto set at 1.5%.  You can drop that down to nothing (which in reality will be 1% after the 20th.)

Over-explained, but hope you get it.

Bitminter is the second client I tried using, and since then I've never looked back. It's a great application that looks nice and is very accessible.

Would you be able to use the information from this thread to improve Bitminter with nVidia GPUs at all? I'm not a programmer by any means, so I have no idea what the feasibility of this suggestion is. Figured I'd throw it out there, though!

Thank you Smiley LTC will be considered soon, right now things are a bit hectic.

I need help understanding the payout transaction fees. Are they a fixed percentage of earnings paid out regardless of how often or is it a fixed amount per transaction? Is there any fee at all charged to the recipients or is the fee paid by the pool? I know there are several recipients of each payout but how does that work transaction fee wise?

Currently there is only auto cash out which is free. That means the pool pays the fees. But you should be aware that a threshold of 0.001 will leave you with a "wallet full of pennies" and force you to pay fees to send those pennies later. A threshold of 0.01 or higher is recommended. I may change the minimum to 0.01 in the future.

Hi DrHaribo.
Could you elaborate a bit more on the last point "New users will have a 1.5% default donation (rather than 2%)".

From saturday and onwards there will be a 1% mining fee for everyone. You can donate on top of that to activate perks. The prepay perk will require 1.5% donation. New users will have a default donation of 1.5% (total 2.5% with the fee) and prepay perk enabled. It's just a default setting - anyone can use the same setup with an older account. If you want you can reduce donations to 0% and only pay the 1% fee.

I've been mining with PPS pools for a few months but due to recent downtimes, and more personal dedication to mining, I figured I'd try a PPLNS pool. 

With PPS pools I've always been able to see a steady "24 earnings" metric.   With Bitminter, in my first 24 hours, I'm looking at less than half of the normal bitcoin payout I'd see.  The worker estimates are all over the map whenever I look at the page, varying as much as 50% down from the near-constant value cgminer is reporting, which is stressing me out.   I can't tell if the estimates on the worker page are bad or if it's actually something wrong with work submission.   cgminer has reported a constant rate the whole time, with <0.1% rejects and no HW errors.

What's a reasonable timeframe in a PPLNS scheme to compare to PPS earnings?  I'm a little nervous to continue here if my stats keep trending like this.

A proof of work ("share") takes a while to be fully paid because it is eligible for payouts from blocks as long as it is still in a shift that is one of the last 10 completed shifts. Your payouts will start small in the beginning as you don't have much work in the 10 last shifts. And if you stop mining you'll still get paid for several hours because you still have work in the 10 last shifts.

Coming from PPS you will probably find the graphs at this URL interesting: http://bitminter.com/stats/rewards

The top graph shows how much each proof of work (share) was paid in the last 500 shifts. As you can see the randomness of bitcoin mining makes it vary a lot. The bottom graph shows how the total cumulative pay for the last 500 shifts compares to expected average for Bitcoin mining.

Bitminter is the second client I tried using, and since then I've never looked back. It's a great application that looks nice and is very accessible.

Would you be able to use the information from this thread to improve Bitminter with nVidia GPUs at all? I'm not a programmer by any means, so I have no idea what the feasibility of this suggestion is. Figured I'd throw it out there, though!

Glad to hear you like it Smiley I could implement CUDA mining, yes, but currently it's not near the top of the TODO list. We'll see what there is time for, it's all a question of prioritizing with limited time.

I've been trying about 7 different mining clients and all of them have heavy fluxations on the MHash rate, is there a way I can stabilize this?

Not sure why that is. Which GPU model is this, and are you running other things at the same time that use the GPU, like Youtube videos?

I did not see any increase in performance vs. GuiMiner. I will stick with that since it doesn't lock me into a specific pool.

What driver are you using? AMD has moved about a year ago (Catalyst 12.5) to separate drivers for the newer cards and 2x00-4x00 cards. I'm not sure that both cards can be expected to work well with a single driver newer than that.

Hi, I'm new here. I appreciate BitMinter having a thread in the newbie section. I recently started mining (again, after a short stint half a year ago in a pool that took my half bitcoin) at Slush's, and when he got a DDoS attack I looked for a backup pool and joined BitMinter.

So far seems cool. It generates for some reason a lot more namecoins than Slush's, which makes it more appealing (not that namecoins are worth much, but still...). I still like Slush's, but might do some more on BitMinter especially if I move to two card mining.

By the way, is 140MH/s on a Radeon 5750 considered good? I'm running at the default clocks.

It's an XFX double d radeon HD 7970. After a bit more research and some trial and error I discovered the wonderful world of firmware based gpu throttling. As soon as the temp even hit 80 degrees it slashed the clock speed in half before even touching the fan speed to try and reduce the temp. I poked around with a few tools and am currently using Trixx's fan control on a curve to have it "properly" increase the fan speed as the temp increases and it's steady at the border of 76 and 77 degrees and hasn't been dropping. I need to do a few more tweaks on the clock setting(it's currently overclocked) as it will occasionally lock up when I'm trying to do mining and another task at the same time. Running just mining it's fine at the current clock settings, but this is my main machine so I'll have to sacrifice some speed for stability. Running at factory speeds I can mine and do other minor gpu tasks and have no issues so I should be able to find a sweet spot after some tuning.

I have a couple other linux boxes running various models of ati gpus at maxx'd settings that haven't been having issues so this one's no biggie. Thanks for the pointers though.

hi i jus done a lil dummy test where i connected to ur bitminter it seems to log on an connect it is mining atm on my cpu as i got a a lame graphics card ( please over look my ignorance i only got into bitcoins a week ago or more)  when it says no open cl compatible does it mean the graphics card in my laptop needs to be different or that i need to upgrade sum software regarding? i'm only doing this to get a feel for it (usin cpu or gpu if possible atm) i knw asic is the future of minning bt we all know thers so very limited availability of asics. however in the future will your bitminter pool work with asics from butterfly( if they ever come) or even other asics. thanks to all in advance for ur help.

Which graphics card do you have?

The pool server already works great with ASICs. There are users in the pool mining on ASICs already. I am working on adding support for BFL SCs in BitMinter client. I aim to have this finished and stable before BFL customers receive their ASICs.


my laptops got a AMD ATI mobility radeon hd 5470 lol i know ryt super rubbish. also any chance ur pool will mine litecoins in future

He's stated several times in this thread that he is considering LTC support, but his "to do" list for improving the BitMinter client is long and LTC support is not very high on said list.  It'll probably happen someday though, just no time table as to when.
