44  Economy / Exchanges / MtGox claim status on: February 21, 2016, 02:00:06 PM
Hello, I just noticed that there's a decision for most of the mtgox claims.
I log on to my account on https://claims.mtgox.com/assets/index.html then I click on the button that says "LIST OF ACCEPTANCE OR REJECTION FOR ALL CLAIMENTS".
But I get the error message on the top of the page "The server could not be contacted or returned an error. This could be due to very high traffic, network issues or ongoing maintenance. Please try again later. "
I've been trying for 2 days but no luck.
Has anyone managed to view his claim status?

51  Other / MultiBit / Change tx fee in Multibit - Possible? on: July 02, 2014, 10:03:21 AM
While Multibit is a great wallet, one thing I don't like is the standard tx fee of 0.0001 or more.
Yes, I know the fee is not for Multibit itself but the bitcoin network (I'm a miner myself).
Yes, I know that if I do not pay any fee for a transaction it might take forever (did once using blockchain.info android wallet and it took 3 days to get 1 confirmation).
However sometimes I just need to transfer BTC between my wallets / online accounts without paying fees.
Is there a way to modify multibit for that? I've read that it was possible for earlier versions by modifying a configuration file, what would happen if I installed an old version?

Πωλείται Litecoin mining rig πλήρες και σε άριστη λειτουργική κατάσταση.
Η ταχύτητα Mining που αποδίδει σε scrypt είναι πάνω από 1700 Khash/sec.
H κατασκευή του βασίστηκε σε αυτόν τον οδηγό
http://www.cryptobadger.com/2013/04/build-a-litecoin-mining-rig-hardware/
και τα περισσότερα κομμάτια είναι σχεδόν ίδια με αυτόν. Όλα αγοράστηκαν από Ελλάδα τον Ιανουάριο 2014, και είναι φυσικά εντός εγγύησης με αποδείξεις.

Το σύστημα αποτελείται από τα κάτωθι:
  • Motherboard: ASRock 970 Extreme4
  • Επεξεργαστής: AMD Sempron 145 2.8 GHz
  • Μνήμη: Crucial 2GB DDR3
  • Τροφοδοτικό: 850W Corsair RM850
  • Δίσκος (USB): Silicon Power Marvel M50 32GB USB 3.0
  • GPUs: 3x Sapphire ATI Radeon HD7950 Boost 3GB DDR5 PCI-E 11196-19-20G
  • 3x VGA dummy plugs (για να μην μπαίνουν οι κάρτες σε idle)
  • 3x PCI-E risers
  • 1x Rosewill 220mm blue LED fan


Τρέχει λειτουργικό Xubuntu 12.10 και ο έλεγχος του γίνεται είτε με ssh είτε με teamviewer (προτείνεται ssh).
Όλα τα απαραίτητα εργαλεία (cgminer, ssh, no-ip κλπ) είναι προεγκατεστημένα. Επίσης έχει εγκατεστημένο πρόγραμμα monitoring για αυτόματη επανεκκίνηση σε περίπτωση που το mining κολλήσει για κάποιο λόγο.
Έχει ήδη γίνει undervolt στο secondary BIOS των GPU για μειωμένη κατανάλωση ρεύματος (περίπου 700W μετρημένο)
Δεκτός κάθε έλεγχος και επείδειξη λειτουργίας. Μπορώ ακόμα και να το βάλω να δουλέψει για σας για λίγη ώρα για να δείτε την απόδοσή του.
Περιοχή Βάρκιζα Αττικής. Μπορώ να το στείλω και οπουδήποτε στην Ελλάδα κατόπιν συννενόησης.

58  Alternate cryptocurrencies / Mining (Altcoins) / One of my 3 GPU does not keep cgminer memory/engine clock settings on: February 09, 2014, 10:56:45 AM
Hello all,
My mining rig has 3x Sapphire 7950's, my OS is Xubuntu 12.10 and I'm using cgminer. All of the GPUs are undervolted to 1081 mV.
I'm having a strange problem: The 2nd GPU, which is between the other two, has a significant lower hash rate than the others!

Code:
cgminer version 3.7.2 - Started: [2014-02-09 12:31:05]

--------------------------------------------------------------------------------

My cgminer settings are
Code:
cgminer --scrypt -o stratum+tcp://stratum.fast-pool.com:3002 -u bomberb17.1 -p 1 -I 20 --thread-concurrency 24000 --gpu-engine 1050 --gpu-memclock 1500  --worksize 256 -g 1 --lookup-gap 2

I tried to change its clock settings from within cgminer, but I see that it is clocked lower than the other 2!
So when I hit 'G' for [G]PU management I get
Code:

I then try to change its clock settings, it changes to 1050/1500 for a few seconds then it goes back to 850/1250!
Any ideas to solve this???

What's going on? Why people are paying so much for them now?

Hello all,
what is your experience/opinions with http://virtualminingcorp.com ?
I was looking at their Fast-Hash One Silver http://virtualminingcorp.com/shop1/index.php?id_product=21&controller=product
which looks like it is available for shipping (am I wrong?)
Only think is that their front webpage says it's $999 while in the carts shows $1499...
