GUI mining - updated Dec 3 with 7970 bugfix, also supports Stratum!

The difficulty changes are not unpredictable. You can look at the estimate here or calculate it yourself. Every 2016 blocks, the network (all of the clients) recalculate the difficulty such that over the past 2016 blocks, using the new difficulty would result in around 10 blocks being found per minute.

True but I was thinking of the longer term... e.g. where will difficulty be in 2 months? This seems harder to estimate, as it depends on unforeseeable events, like bitcoin getting a sudden burst of publicity.

Better change ur graphics card if u want to mine.
The investment u make is worth more than u can think.

Mind me asking what you're earning at the moment with your 6870? I am tempted to buy a better GPU. Hard to know if it's worth the investment if difficulty is going to keep climbing (unpredictably as well.)

For the past 4 days mining i got around 19btc, on average 4btc daily, running 23/7

For long term, the next difficulty will be <=70000 , & then after 2 months it will be 23000909.

In 2 months not a single 5970 is enough to mine, u need atleast 2-3X 5970 to mine.
U better instead of mining try buying & selling, that will be easy & profitable.

When I try to run guiminer.exe on my inspiron1520 dell laptop I get this error: "Couldn't find any OpenCL devices."

From guiminer.exe.log:

Exception TypeErrorERROR:root:Exception:
Traceback (most recent call last):
  File "guiminer.py", line 836, in <module>
  File "guiminer.py", line 518, in __init__

Could anyone tell me what I need to do and if my laptop is just too weak to even bother?

What kind of graphics card is in your laptop? You probably need to download an up to date driver for it with OpenCL - assuming one exists.

8600m GT

8600m GT

Download and update your driver from here: http://www.nvidia.com/Download/index.aspx?lang=en-us

ugh I soo do not want to update my driver and potentially fk something up and then having the trouble of trying to reverse back to an old version which I don't even remember anymore where I got

I have a similar graphics card to you (8400 GS) and mining about 0.3 BTC a day at 1.5 MHash/s... so maybe not worth the bother.

[hazek]

Too late for that now 

[hazek]

Driver updated, got the miner running but the status bar says:

Shares: 0 accepted, 0 stale/invalid           4Mhash/s



Is this how it's suppose to read? Do I need to use any flags?

[theGECK]

That looks right. At 4Mhash/s, it will probably take a bit of time for your first share to be accepted.

[hazek]

Yep, just found my first one!  

Thank you very much to everyone who helped me out with this!

In 2 months not a single 5970 is enough to mine, u need atleast 2-3X 5970 to mine.

Oh FFS, rich gets more riches and us poor peoples are stuck because can't do constant upgrading :/

[fizgig]

Anyone know why Quadro FX 1800M running on XP isn't seen as an opencl device?  I installed the nvidia driver a month ago.

edit:  Nevermind.  I didn't see that I had to install the ATI Stream SDK (even though I have an Nvidia card).  All good now.

Don't listen to this guy. Either he was being sarcastic or he doesn't know what he's talking about. I doubt we'll see difficulty increase much faster than the 30% increments we've been seeing.

[fizgig]

I'm still not quite understanding the "Difficulty 1 hashes: X" number and I'm very interested in what it means.  I've read that it tells you how many close hashes you've calculated but what does that mean?  If that number is X, does that mean if the current requirement is for 14 leading zeros in the hash, that I've made X number of hashes with (14 - 1 = 13) zeros in it?

[BitLex]

no,
on pools you work on easy hashes,
means say the current requirement is for 14 leading zeros in the hash to solve a block, you are trying to find hashes with say at least 3 leading zeros.
you'll find and submit hashes with 3,4,5,6,7,8,9..... leading zeros (which all get you a share in the pool) and every once in a while someone finds a hash with the required 14 leading zeros and bang, pool gets the block, everyones happy.

Sorry, by tyoing mistake i added double 09.

[BitLex]

so saying

wasn't a mistake?

Question: Can we run out of difficulty?
