Does anyone live in Belgium or Luxembourg and does know if there are any taxes on capital gains?

Can't find anything on Google about Luxembourg and only one website about Belgium says there is a new 33% tax for gains with cryptos.

How can I change the VDC for my AMD R9 290 / HD 7950 on Ubuntu/Linux to reduce the temps?

The MSI R9 290 Gaming is currently at 92 C with p0 f100 e900 m1250. My first Sapphire 7950 with VDC 1.09 is at 67 C p20 f80 e1040 m1250 but my second 7950 with VDC 1.25 is at 81 C p20 f80 e1040 m1250.



"atitweak -s" shows 0 VDC for the R9 290. How can I get the info about the current VDC for the R9 290 in the first step and change it in the second step?



The (second) 7950 doesn't change the VDC even if I enter "atitweak --set-core-voltage=1.09 --adapter=1"

atitweak --set-core-voltage=1.09 --adapter=1
Setting performance level 0 on adapter 1: core voltage 1.09VDC
Setting performance level 1 on adapter 1: core voltage 1.09VDC

1. AMD Radeon HD 7900 Series  (:0.1)
    engine clock 1040MHz, memory clock 1250MHz, core voltage 1.25VDC, performance level 3, utilization 99%
    fan speed 80% (3631 RPM) (user-defined)
    temperature 81 C
    powertune 20%

Is the "performance level 3" a problem because above it shows "Setting performance level 0 ..."?

P.S. If you have a STILT BIOS please leave a link

My GPU rig is much more stable than in 2014 but sometimes only a hard reset works because of GPU freezes or OS (Ubuntu) freezes and I can't access my rig by remote (internet) anymore.

So what kind of hardware do you use to hard reset your rigs by remote?

I'm running

Ubuntu 15.10
AMD drivers radeon-crimson-15.12-15.302-151217a-297685e
Genoil's ethminer

but I only get 10 MH/s because the GPU clocks only at core 501 MHz (normal 1000) and memory 1400 MHz (normal 1400) and sensors say 95 C / fan 100% (3500 rpm).

I've read there was a bug in 2012 if you run also a youtube video but everything is off except ethminer.

If I change the settings like this

Code:

aticonfig --initial
aticonfig --od-enable
aticonfig --adapter=0 --od-setclocks=1050,1450

the gpu core clocks still at 501 (not changed) and the memory now at 1450 (changed).

If I change the settings like this

Code:

aticonfig --adapter=0 --od-setclocks=400,1250

the gpu core clocks now at 400 (changed) and the memory now at 1250 (changed).

Thanks for every hint!

P.S. Are there any active links to download a Stilt BIOS for the 7970 and 7950?

Hab gerade eine deutsche Seite gefunden mit einer guten Übersicht rund um die Themen Blockchain Technology Bitcoin Geld 2.0 Decentralized Exchanges und ein Bitcoin Interview mit Tim Draper das es echt auf den Punkt bringt!

Weiß jemand, ob es eine ähnliche Übersicht auch zu deutschen Bitcoin Börsen gibt?

Does anyone have experience in building a server case for the KnC Neptune/Titan or knows some links?

I'm wondering why KnC delievers 10000 USD miners in peaces instead of using a professional server case. Their "new modular cases" look so damn dilettantish and are total crap if it comes to colocation.

Does anyone know a Multi Pool Switcher software for Linux like e.g. "Awesome Profit Switching" or "Miner Control"?

Is it possible with a Scrypt-ASIC to get fully automated payed in Darkcoins?

Maybe with a pool who payes the Scrypt miner in DRK (couldn't find one) or e.g. an exchange which would change fully automated the incoming BTC from your miner (many exchanges don't like that) to DRK and sending them fully automated to your wallet on your phone or PC?

I'm pretty new to remote controling computers, so does anyone know the best way to remote control a Xubuntu miner from MacOS with dynamic (changing) IP addresses for both machines?

I've already found some links ...

Ubuntu Remote Desktop: http://www.makeuseof.com/tag/ubuntu-remote-desktop-builtin-vnc-compatible-dead-easy/

XRDP: http://www.youtube.com/watch?v=Ex6SXzjcKb4

Vino: http://www.ehow.de/xubuntu-remote-desktopanwendung-aktivierst-wie_8522/

... but I'm not sure if they support dynamic IP addresses and what someone with experience in remote controling computers would recommend for mining.

Thanks for every hint

I've tried now more than one week to compile ccMiner from https://github.com/djm34/ccminer for Ubuntu 13.10, but I'm stucking since days at the point where I start ccMiner and get the following output.

Code:

[2014-07-16 14:29:14] Unable to query CUDA driver version! Is an nVidia driver installed?

I guess ccMiner doesn't find the installed Cuda toolkit, but I have no idea how to point to the Cuda toolkit directory, except the way I do it in my Howto.

This is my current Howto:

sudo add-apt-repository ppa:xorg-edgers/ppa -y
sudo apt-get update
sudo apt-get install nvidia-340

reboot

sudo apt-get install build-essential
sudo apt-get install automake

sudo apt-add-repository ppa:aaron-haviland/cuda-5.5
sudo apt-get update
sudo apt-get install nvidia-cuda-toolkit

cd ccminer-master
chmod +x configure autogen.sh
sudo apt-get install libssl-dev

export PATH=$PATH:/usr/lib/nvidia-cuda-toolkit/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/nvidia-cuda-toolkit/lib

reboot

./autogen.sh && ./configure && make

Thank you for every hint

I've pre-ordered 4 Viper ASICs from Alpha Technology on 4th of January 2014, payed 6540 GBP with Bitpay on the same day, cancelled my pre-order on 2nd of April 2014 by email, but got neither any answer from Alpha Technology nor the promised 75% (Terms of Order - Cancellation & Refund Policy) of my money back. In the meanwhile I've sent them (customer@alpha-t.net) 3 emails, but till now I've got no refund and no answer at all.

Did someone else experience such fraudulent behaviour?

Edit: Yesterday (June 20) I've received 1 email from payments@alpha-t.net and the refund of 75% after 11 weeks and 2 days.
