I have a Biostar TB85 with 5 gpus and have had zero problems with it. Only had it 6 months but mines 24/7. Don't own the Asrock board you mention but have had several others without issue.
I see that motherboard has 5 pcie 1x slots and one pcie 16x slot. So a total of 6 slots. Can you use 6 cards on that board? Also do you need dummy monitor adapters on those cards? |

does cpu power matter or do you just get the cheapest cpu the mobo will support?

UPDATE: I've tried the Mnemonic Code Converter, unfortunately I was not able to find any of my address from that wallet. Definitely I will try other settings for that tool tomorrow. Thank you all who involved.
Don't do that. You shouldn't be entering your seed on any sites! Your seed should always be kept secret. Please open your restored wallet in electrum, press ctrl+A to bring the addresses tab into view and then tell me whether there are any familiar address listed there. Also what version of electrum did you use to originally create this wallet? 2.7.18? Did you increase the gap limit of your wallet? |

You probably have created a wallet with two-factor authentication, where transactions are cosigned by Trustedcoin.
An extra fee is charged per transaction, with a discount if you buy prepaid transaction.
Click on the Trustedcoin icon in order to see the billing options.
Thanks. This was the reason. Now i got another question: When i want to send another transaction, over 80% of my balance. It increases the dynamic fee to 0.0021 , which is really high, it comes even with a warning by electrum. Does this have to do something with the fact that i have coins on 3 different receiving address so it costs more fee to transfer them all at once to another address ? It depends on the number and size of inputs too. Have you received a lot of small amounts from say faucet sites? Those small amounts cost a lot to spend. On newer versions of electrum you get a slider on the send tab that allows you to lower the transaction fees at the cost of slower confirmation. In my experience even with the lower fees you get pretty fast confirmation. So perhaps you should upgrade to the latest and greatest electrum  ? |

Hello,
So here is my transaction: 432251090ecb7f0b18f69d1854981dae60269b55649ac2fb9a0b337556a7b83d
I've sent some coins and yesterday the transaction was marked as "Verified". My balance was 1.09077109. I had the terrible bad-luck to find my PC is not booting anymore as my SSD simply died. So no backups of my wallet.dat or anything else. Just my seed on paper.
The first thing I've done is trying to restore my wallet using my seed. And as some may know already, I found that my balance is 0.
Is it any way to get those coins back to my wallet? Any help will be much appreciated.
Thank you!
p.s. Electrum 2.7.18. Multiple address change were enabled. Dynamic fees as well enabled.
OK you can try a few things: - In case you haven't already done so enable multiple change addresses in your restored wallet too. Tools > preferences i think. - Change the server you connected to. Tools > network. See if that fixes the balance - Run the following command on the console tab and tell us what it outputs: wallet.is_mine("1HtDHigRkCPs1Ux6MPhXZ3N85i6ASnm1uA")

No you have misunderstood. If you look at that github issue I've linked above then you can see that breadwallet supports bip32 (HD wallets) and 39 (standard for seed mnemonic/wallet words/passphrase to seed conversion) but not bip44 (key derivation standard). Wallets that use bip39 and 44 cannot be restored in breadwallet simply because the derivation path (bip44) is different from what bread wallet uses. That is what he meant by this comment on reddit. The phrase itself (bip39) is not the problem. There is nothing in the phrase that tells you which wallet it came from so if you support one bip39 wallet you support them all. |

I deleted my post above for a reason. I was not sure what i was talking about I read somewhere on the forum that the seed is effectively 124 bits after all the entropy loss due to the seed version/checksum. But then I read the code and I saw that it generates a 132bit random number. Then it keeps incrementing that number until it gets one that hashes to the correct seed version. To answer your question is the entropy loss from that hashing worth 8 bits? Sorry IDK I'm not a cryptographer. |

According to the developer Breadwallet doesn't allow you to recover all possible bip39 compatible phrases
Where does he say that? bip39 is not the same as bip44. |

Hi there. In my Electrum wallet that i imported from blokchain.info.
When i try to send max amount it show me wrong number . for example.
i can see .013++ as my whole balance but when i try to use the max option when i am sending it show me only .012
Why i can not use my whole balance in electrum?
Is the money in your wallet from lots of small payments? Like from faucets? |

I have created an offline wallet on an old phone.
I can create an unsigned transaction with the corresponding watch-only wallet and show it as a qr-code so it can be read by the offline phone.
With the offline wallet I go to "send" and read the qr-code (the unsigned tx). Then I can see the unsigned tx on the offline phone (as an info) but i cannot sign it or do anything useful with it (despite showing it as a qr-code again)...
You have to use the load transaction option not the send option. I'm not familiar with electrum for android so all I can suggest is that you look for a load transaction option. |

Abdussamad: I used the Console ismine ('XXXX') on the address that I got when I decrypted my Private Code and it returned "false". But I initiated the Sweep from Electrum.
I have the Transaction ID--can I use that to help track this
Again--Thanks
A sweep does not import the private key. Look up the transaction ID on a blockchain explorer (or post it here) and look where the coins went. Check again with that address. Yeah I meant the target address that should belong to your electrum wallet. |
|
|

To bring the addresses tab into view press ctrl+A. Alternatively you can switch to the console tab and use this command to determine if an address belongs to your wallet: ismine('the address you swept the coins to')
If it returns true then the address is in your wallet. |

look at the orb icon in the bottom right. is it green or red? if it is not green thenclick on it and select a different electrum server. you can also do this via tools menu > network.
btw the difference between 34mbtc and 33.9 mbtc could just be the transaction fee. a sweep is an on-chain transaction so there are transaction fees involved. if you see 33.9 in your electrum wallet then you already have all your coins there.

Okay thanks a lot sir was really helpful . One last thing tho . what would be your advice import the BC.in in the electrum ? or just make new wallte in electrum and and use both?
If you need the addresses used in Blockchain.info, just import and remember the seeds. If not, I would recommend you to just create a new wallet in Electrum and use only Electrum. Blockchain.info is far too unstable IMO. Yes I agree with this advice. |

I have blockchain.info web-wallet that i want to import to Electrum desktop wallet can i do that?
Also i am kinda newbie . Can i ask what is the best way to use Eletrum safely .I only have one pc that is always connected to the internet.
How to save my Electrum on an offline usb ?
If you don't know how to get your private keys in blockchain.info, just create a new electrum wallet and transfer all your funds to it. Getting non-imported private keys from blockchain.info is a tedious business. You'll get much less headache by doing that. That is really a good option . but can i have a link for how the steps to get blockchain private keys . just for learning. note that it is not a good idea to mess around with the private keys of an HD wallet like bc.i or electrum. ok THanks sir but if i did this can i still use my wallet from blockchain web wallet to ? or once it is imported in Electrum it will be removed from blockchain?
You can use the wallet in both places. |

Use file > new/restore to create a new wallet if you already have an existing wallet. Otherwise just run electrum and it'll show the new wallet creation wizard on first startup.
Select 'standard wallet' type. Then 'I already have a seed'. Then on the seed entry screen click on 'options' and check 'bip39 seed'. Enter your blockchain.info wallet seed words. The rest of it is just clicking next, next, next.
You can use electrum safely on an online PC. Cold storage and such are only for advanced users and people with lots of bitcoins to secure. Since you are just starting out running electrum on your own PC is enough.

edit: I missed some posts Why not use addrequest in combination with getaddressbalance? if an address has a balance then it's used and you get a new one with addrequest. |

That's actually a very nice outlook. People like you force us to look deeper and everyone learns something new from that. So yeah ask away Well thanks a lot, I was about to close this thread and then boom! someone who understands me  Now that we know why we are talking, is it possible to calculate encrypted key on a calculator on some thing like this: https://asecuritysite.com/encryption/PBKDF2zPBKDF2 is not an encryption function. I explained that above but it's also explained on that page: this is used to create an encryption key from a defined password, and where it is not possible to reverse the password from the hashed value.
A hash function is not an encryption function. Electrum uses AES to encrypt your seed: https://github.com/spesmilo/electrum/blob/59ed5932a859fd807232960404764b8686355830/lib/bitcoin.py#L119 |
