Re: Gridcoin (GRC) - first coin utilizing BOINC - Official Thread
what kind of gpu do you have and what are your settings? I can mine fine with mine with no decrease in hash speed so it is definitely something on your end.
When I use an external cgminer, I only got ~105KHPS.
I thought Scrypt Sleep is already required.
I was getting 570KHPS earlier on Friday. Ever since I re-sync on Gridcoin with a loss of 7K GRCs, I started getting 105KHPS.
So I suspect this must be something related with Gridcoin client monitoring the GPU usage and reduce it accordingly due to BOINC credits.
Other than that, I can not think of any other reasons.

Scrypt sleep is not functional @ the moment. Try an external gui-miner and see what kind of speed you get.
I am using the embedded cgminer downloaded along with the Gridcoin client. I used to get 570KHPS. Now it is 90KHPS.
My daily credit is about ~1600 these days. Not that high. My Scrypt sleep level is at only 69% currently.

Are you mining with with guiminer external to Gridcoin, or internal miner?
BenHur and Traderman, thanks for the reply and help.
Yes, I tried rebuilding the blockchain after blowing away the Roaming directory, reinstalling the client etc. but it did not help.
I went all the way back to early march and found one wallet which can be recognized by the client without the "salvage failed" error.
However, after syncing up, it did not retrieve all the coins I had from Friday. There is a difference of 7K coins lost.
I suspect that I was in a hard fork somewhere and kept mining without realizing the fork. I just don't understand why the 7K coins were accepted by the network just fine. Yet when I sync again, it just disappeared.
Now I started mining again but found out that my hash rate dropped to ~100KH. Many times the miner is disabled automatically.
I suspect that this is caused by the Scrypt-Sleep algorithm but am not sure.
My Leaderboard Posistion is ~100. 100KH is just too slow and I don't know how many days will it take to solve a block.
Can you guys comment on the new Hash rate? Should I accept this hash rate or there is something I need to tweak to improve it.

Try that, that should work!
Have you tried to rebulit the bolck chain?
You can delete the files in "C:\Users\your PC user name\AppData\Roaming\Gridcoin" ,only leave gridcoin.conf and wallet.dat.Then run the wallet software Run as Administrator,the wallet software will restat and update.WHen the update done,it will download the blocks chain.
Hope it works.
It seems Rob has updated the gridcoin.us back to 2.1.0.7. I downloaded it and was able to sync.
However, I kept getting "wallet.dat corrupt, salvage failed" errors.
I tried all my backup wallets and all with the same error.
Also tried "gridcoin_qt -salvagewallet -rescan -reindex" with no luck.
Anybody has better idea on how to recover the wallet.
I was running 2.1.0.4 earlier. Could that be a problem?
Does anybody have the 2.1.0.4 version so that I could try whether I can recover the wallet?
Your help will be greatly appreciated.
