i wanted to add it at first, but couldn't generate any interest. some chatter about devs being scammers and client being broken.

Qt just freezes and shuts down

Ok, I used the backup wallet I had made from a few days ago, it syncs up to block 40319 then I get "system error:CDB():can't open database file wallet.dat, error -30974" and then it crashes and I get "A fatal error has occured.  Gridcoin can no longer continue safely and will quit.  
EXCEPTION: St13 runtime_error  
CDB():can't open database file wallet.dat, error -30974
c:\Program Files (x86)\Gridcoin\gridcoin-qt.exe in Runaway exception"

I was doing a resync and an update a few days back and got these same error messages.  I then restarted the client and they went away so I wrote it off as a fluke.  I think a fresh install and new wallet would be in order, I would love to recover those 6K though.

So basically i am not dedicating any GPU power towards BOINC. Only my cpu is contributing to BOINC projects??

If that's the case then this coin is not energy efficient at all, its just forcing you to use your cpu for boinc while wasting gpu power on gridcoins, i could be dedicating gpu and cpu power to boinc instead of mining for gridcoins.

Hashing speed was around 2400Khs.  I do have a backup from a few days ago.  This is something I SHOULD know by now, but I have never dealt with it before, is it okay to use a wallet backup from before I mined those blocks?

I fall out of sync 1-2 times a day, that 6K was mined over the last 36-48 hrs or so, I was periodically checking the block explorer and rebuilding the block chain as needed, so I know I wasn't forked for 2 days or something.

And why is the .bak file all of a sudden 960kb, about the size my wallet.dat used to be, and now my wallet.dat is 80kb?

I managed to get the client sync'd again, by using the .msi, and ensuring the QT was run as Administrator (this was probably the problem before). I'm still getting the crashing when I try to run Gridcoin at the same time as Boinc, though.

I've triple checked the Boinc folders in gridcoin.conf, and ensured .NET is up to date (there was an update to run).

My gridcoin.conf below..


Any other ideas you may have would be greatly appreciated.

Should the boinc folders have a trailing slash or not? Have tried with both so that's not the issue, but just want to ensure I've got that right.

I tried to give this a go last night. It took a while to get the client sync'd but figured that out eventually, then got BOINC installed and working ok.

When I try to run the QT again to try mining, however, it crashes on startup - every time. Any ideas?

This is just way too difficult to set up.. i'm getting gray hairs already.

I think I'm making progress.  lol

I'm not running an external version of cgminer.  I'm trying to run it within the Gridcoin mining module.

However I have a message on the bottom left of my screen where it should say "mining", it is saying process has exited, so the requested information is not available.  There are no hashing showing so I don't think it is doing anything.

On the configuration screen it shows my GPU and I've enabled it.  I gave it values for worksize, intensity, and lookback.  I did not give it a concurrency value. 

I also set the config file so it would pool mine because I was hoping to get some idea of I was actually mining.  lol

Any ideas?

Regarding some other things that don't look right.  My wallet was in sync but as I was waiting to see if something happened with the miners.  After a while the wallet showed out of sync and showed it was 3 blocks behind and seemed to get stuck there.  When I shut it down and restarted it again the wallet immediately showed it was sync'd again.

Edit:  After the restart it got out of sync again fairly quickly.

one of the biggest chinese website 163.com reports Gridcoin in one article.

Thanks Traderman!  I saw that link and was unsure because of this line in the instructions.  "Download the BOINC 6.6.38 file (current version) and install it."  However BOINC 6.6.38 isn't the current version anymore. 

I'll get 6.6.38 just to make sure I'm on the same version as the instructions.  6.6.38 is almost off BOINC's download page though.  There have been several newer versions since these instructions were written.

Thanks for the reply!

I found Gridcoin when I was grumbling about the lack of information in CureCoin's thread.  Someone in a chat room mentioned Gridcoin so I finally read through this entire thread.  Let me say first off, Rob, you are top notch.  Very responsive and you obviously work your a*s off!

So I will be joining the fray as well.  I really like what you are doing here.  I don't understand the idea behind most crypto-currencies.  There are just too many clones now with new one's popping up every week or even every day.  However, I believe Gridcoin could literally change the world and that is why I'm so excited about it.

So I've got three computers now (not the most powerful) and I will begin working to set them up but I've also got three more in route that are set up with more intense mining in mind.  So I hope to be a contributor quite soon and will join the team when I get things working.  Again I think the development team and overall support is top notch.  I just don't see what else people can ask for.

I am super excited about this project!  Well done!



One quick question and I apologize in advance if this was listed before but there has been a great deal of changes so I want to make sure I understand how this works.  If I'm running three computers do I need to have a wallet installed on each computer?  From what I've read I believe that is the case but I want to be sure because I would prefer to have a single wallet if possible.

Yes,I run Gridcoin-qt by itself , no other clients.But it doesn't work.

I want to know:
If my gridcoin wallet is always out of sync,can I receive or send Grc?
