I think ever since the network hashrate increased to 100 mhash there are a lot more stales now. I think because there is a lot more people hashing there is a greater chance that someone else discovers the block before you do. So if someone else beats you to it, you get a stale. I think the sleep algo will improve that because instead of competing so much, you can do Boinc work while there others are hashing, and then when your turn comes you won't get as many stales. I think that is the way the sleep algorithm for Gridcoin will work.

did you try work size 256? I suggested that in one of my previous posts. Why is gpu2 running @ 750?

I have been running all my stuff in Win7 and so far no problems. I have never used win8 so no idea what the situation is there.

Try installing Gridcoin and Boinc into c:\Program Files folder. There may be some permission issues for folders.

I run my stuff on Win7 64bit, so I do not know how things will behave on XP. Xp is very old so there might be some kind of comparability issues that may be causing such behavior. I suggest you get win 7, you will not have any problems.

What intensity and concurrent threads are you running? Also what is the temp of the gpu under load?

I had an issue with scrypt mining on one of the rigs that had 3 7950. I had 4 gig ram and once I upgraded to 6 all gpu were running full speed. I am not sure if that is the same issue as you are having. You can try and it and see if it works.

I think I had that once, but once I ran it as admin it seemed to work. What dir did you install Gridcoin in?

How much ram does the system have?

You can join the cpu mining pool, that would porbably work for you.

Are you running client as Administrator? Did you specify the boinc install and data dir in gridcoin.conf ?

We are gonna need a lot of power to make it to the top 10.

Let's see what happens.

What was the gist of the conversation?

All the other coins are just clones of the litecoin/bitcoin with different parameters. So that client has been proven over time and there is no bugs in the code. Gridcoin is radically different, there are so many changes to the code of the wallet software. If you are running an exchange, it is a big risk to be taking to run a wallet that has a lot of new stuff that has not been thoroughly tested in real world conditions. So if you think about it, it is wise for them to wait for everything to be proven reliable by the community before adding the Gridcoin client on an exchange. About a month ago there were a lot of synching issues with the client, can u imagine running this on an exchange and having these kind of problems. It becomes an absolute nightmare for the operators of the exchanges. That is why these new coin clones are quickly added because it is a cut and paste job for the operators of the exchange and they know they won't have any issues with the client. Gridcoin has to be proven reliable over a good period of time before any of the major exchanges step up and add it. This is why I think Gridcoin is taking so long to be accepted. Keep in mind the scrypt sleep function will be added now, so there are a lot of things that still need to be done for development of the client. So everyone in the community is gonna have to be very patient, this is a complicated project and it needs time. This is not just some shitty clone coin.

I think exchanges are waiting till everything is complete. they see a lot of changes happening and maybe they want to wait till everything is set in place.

I always make backups. That is the #1 rule in dealing with anything computer related. Also make backups of the backups and store on different media. dvd, usb etc..

That block should be in your wallet. I have never had a found block that did not register in the wallet. I use guiminer scrypt and I run it externally to Gridcoin.

Do -salvagewallet and you should be fine. Always worked for me.

You mean 800 kh/s
