- Compute 3.0 is broken. Need to fix that.
- Also I got a couple of not validate on the cpu when mining x15 on a 750ti. Need to investigate.

Working on Spreadminer 6 for the donators. This will support compute 35 devices as well as being faster than version 5.

Thanks for that sample, I can see there it is 1st flagged in CTxOut line OP_DUP. I dont seem to have an error in that place:

That worked - thanks a lot!! (and yeah - 3.0 - validation issues)

In VS right click on the project, select Properties and under CUDA C/C++ and Device remove the compute_52,sm_52 part (that's for 900-series cards) and leave the compute_50,sm_50. If you also want the 660 to work you need to add compute_30,sm_30 but that might run into CPU validation issues.

Thanks - Question #2: I got it to compile x64 (first time to actually get ANYTHING to compile  ), but I can't get it to compile the 32 bit - I get "Unsupported gpu architecture 'compute_52'" - quick solution?

(Edit: I have 750 Ti's and 660's - so if I could "turn off" the 5.2 and "turn on" the 3.0, that'd be great!)

You can keep your recent driver. But nVidia CUDA installer often changes driver despite the user choice. In that case you will need to reinstall your favorite driver.

Question about CUDA 6.5 Toolkit - when I install this, it wants to downgrade my driver from 347.xx, do I have to allow this, or will it function with my current drivers?

Sounds like it was stale/orphan. Around the "generated 2385.965241" part there should be something about it being "stale". It differs for some wallets but here's an example from a random wallet log:

not sure if I can tell what it is, is there an accepted failure rate, what % is the norm?

Works - partly ...

Can someone tell me which flag I have to set to get it compile with curl ssl support in MSVC 2013 Express ?

When I try to connect I get HTTP request failed, protocol https not supported or disabled in libcurl.

Of course my local libcurl lib is ssl enabled and the one in the "compat" dir also from what I see.. So it is probably an option somewhere ?

sounds low level, but maybe was orphaned block?

 am solo mining DGB in the hope that they go up in value.
I got one "yay" this morning and this went into my wallet which is the official version and I got 2386.045241 DBG
I got another "yay" this afternoon but nothing went to my wallet, I can see things like "AddToWallet" and "ProcessBlock: ACCEPTED" and "generated 2385.965241"  in the debug file for the wallet
I am using ccminer sp version from a few days ago from git which I compiled myself,
My question is what do I look for in the log to tell me what the problem is?
Does my wallet need to be unlocked during mining, although I am fairly sure it was locked when I got the 1st "yay" this morning
I've spent a couple of hours googling this issue and not found anything relevant, apologies if this is a noob question that I should know.

And you know what, its the same since XP and works also on Windows 10 ! :p

The sha256 algo implementation might come in handy because a coin with modified sha256 is coming from earlz no less:

https://bitcointalksearch.org/topic/ann-sup-supcoin-pluck-algorithm-just-launched-mine-now-950084

Install Visual Studio Express 2013 for Windows Desktop
Install Nvidia CUDA 6.5 Toolkit
Download the ccminer source code
Open the ccminer.sln file
Make sure the compiler is set to "release" and "Win32"
Rebuild solution

Then you should see the ccminer.exe in the release folder

Works on 750ti. You can remove compute 5.2 in the projectfile and try to recompile until I find out whats wrong. Or revert to an earlier build

I know, i already compiled a lot on Windows but this one seems to have some strange issues...

Has anyone got build instructions  from source on Windows 8 ?

YAAMP ROUND-ROBIN CONFIGURATION--

The following is a working Windows Batch File for a GTX 960 using the yaamp auto-switch.  The "-r 0" flag allows yaamp to cycle through algorithms until the high-paying algorithm is served up.  The long "password" should be comma separated and have no spaces except immediately after the "-p".  Each line is broken by the formatting process on this blog after the "-p" password flag.  I inserted 1 extra blank line between each 1-line command statement for clarity.

There is no such simple solution on Linux, primarily because BASH does not have a goto command.  Save this text as "looper.bat".  Code follows:

:loop
