Wallet

 Please backup your wallet.dat file before doing anything if you are having trouble accessing your QT wallet. The wallet.dat contains your private keys for each address, without those you will probably lose access to your Ravencoin.

Symptoms:

Restore wallet

Quick restore guide

Same steps as Wallet does not sync just put back your backup wallet.dat instead.

Full restore guide

This guide assumes you are starting fresh on a new computer.

  • Start by installing Raven-QT wallet follow General wallet guide if needed, skip encrypt and backup for now.
  • Once you have Raven-qt running and fully synced, quit raven-qt and wait for it to fully exit.
  • Open your Data folder, the default location is shown below this guide.
  • Move the wallet.dat that is already inside your Data folder (Raven) folder to another location ie. desktop, and put your backup wallet.dat here instead. If you used a memorable name for your backup wallet.dat we need you rename it back to wallet.dat now.
  • Launch Raven-qt and you should see your funds available.
Windows: %AppData%/Roaming/Raven
Mac: ~/Library/Application\ Support/Raven
Linux: ~/.raven

Note that " ~/ " is the home folder for linux and mac, not " / " root.

Wallet does not sync

The first thing to try is to re download the blockchain.

  • Close raven-qt completely, wait for shutdown window to disappear.
  • Open %AppData%/Roaming folder and move Raven folder to desktop.
  • Launch raven-qt and wait for blockchain to sync completely, then shut down completely.
  • Move wallet.dat from your old raven folder on our desktop into the freshly created Raven folder in %AppData%/Roaming/.
  • Launch raven-qt, and all should be well.

There is a guide on the Community forum, and here Fixing no sync.

Crash on start up

The first thing to try is to re download blockchain. Follow same steps as Wallet does not sync

There is a guide on the Community forum.

Transaction stuck

Try deleting the downloaded blockchain, and resync.

Extra amount of rvn went missing when I transferred coins out of the wallet

Try from within the wallet: Help / Debug Window / Console: and write

listaddressgroupings

This will list all your addresses and their balance. Check for the "missing" amount.

This appears to be a display issue that happens rarely.

Change data location

Registry location

\HKEY_CURRENT_USER\Software\Raven\Raven-Qt\StrDataDir

Or you can start raven-qt with the flag below, to have it ask again as per initial installation:

-choosedatadir

Transaction to large

When the wallet has too many small transactions to a single address, it can cause a issue. wallet groomer Ravencoin fork by Brianmct

Mining

All miners

Symptoms:

Crash on startup.

Check if Antivirus/Windows defender has deleted your miner.exe file, check if the .exe file is still in your folder. Fix by setting an exception.

Crash/reboot after some time

Check the power limit for the cards, 65% - 85% is common. x16r algo spikes the power draw so we need headroom in available wattage. Remember that the TDP for a card is an average draw of the card and in short spikes the total draw can be much higher. This is why the GPU manufacturers recommends much higher watt PSU than the TDP listed wattage of the cards would otherwise suggest.

Naming you Rig on the pool

On yiimp type pools you can use the password field like:

-p c=RVN,TitanV  

,a comma is used to separate arguments, do not use special character or spaces in your rig name. Other pools usually set name by WALLET.rigname like:

-u RT2r9oGxQxbVE1Ji5p5iPgrqpNQLfc8ksH.titanV


When troubleshooting it is helpfull to have pause at the end of our bat file, so you can see the errors from console.

ccminer -a x16r -o stratum+tcp://miningpanda.site:3636 -u RBjAZ4fgoXfMC1ujzs7XKreMxJAL1r9fhT.titanV -p c=RVN,titanv -i 20 -N 600
pause

Suprnova gives error on launch

Check that you have created a worker on their webpage and supplied a password.' -u LOGIN.worker -p x ',also check their getting started on rvn.suprnova.cc start page.

Hash rate is changing/low

This is normal as the x16r algo is changing 16 times in each block, determined by the last 16 bytes of the last block. We need to look at a 2-3 hour averages at least to get a better average hash rate to compare, try adding ' -N 600 ' at the end of your bat file, it increases the average reporting time (default is 30).

Getting a lot of "rejected" shares

A rejected share means 2 possibilities:

1. The submitted share was invalid (bad hash of good data). This is caused by a GPU error on your end.

2. The submitted share was stale (good hash of bad data). This is caused by latency or lost data over the network between you and the pool.

If you're tweaking your GPU a lot (customizing power/frequency/voltage/etc.) then try backing down a bit and see if you get less errors. You should also check to make sure connected to the closest pool possible (e.g., don't connect to a pool in Europe if you live in the USA).

Nevermore / ccminer

Symptoms:

Crash on startup

Check .bat file that name miner at the start is the same as the miner in your folder. Nevermore uses 'ccminer' 2.2.5 might be 'ccminer-x64'.


Sgminer / Avermore

Symptoms:

Crash on startup

try adding

--gpu-platform 1 

or

--gpu-platform 2 

Brianmct has a good Getting started wiki on github

Long startup time

First time sgminer starts it compiles a kernel for all the cards, it can take several minutes.
