My current rig has: 1 x Vega 56 blower 1 x EVGA FTW2 1070 3 x RX580 Nitro + 1 x RX580 Red Devil It’s nice and I can mine either Ethereum with the hybrid Claymore miner or ZCash (albeit I still need to tune it because it crashes). Unfortunately, the airflow is messed up: Vega blows towards the rear Nitro+ blow towards the front The other two are OK with no discernible preference. So, I thought of adding fans to build a specific airflow, but I’ll need to build…read more
Following my writing, I’ve rearranged my rig to have the Vega card on one edge (where the intake fan would get “fresh” air from the room rather than heated air from one of the other cards). Results are quite epic. With the settings: Frequency % = 0 Voltage control = manual, with the last 2 entries at 1100 mV Memory speed = manual. set at 950 MHz (new) Memory voltage control = manual, last entry set at 950 mV Performance profile = custom Fan speed = manual, between 400 and…read more
TL;DR: Keep your Vega cool if you want high hash rates! Recently, I’ve got a AMD Vega RX 56, to see for myself how good it is on mining. If you ignore the power consumption, it’s quicker than my RX580 cards. I’m getting 33+MH/s consistently: At the beginning of the session I even got 36MH/s, but, as temperature rose, the hash rate dropped to 33+ stable. Unfortunately, my setup is less than ideal: No decent linux support and I haven’t got the time to tweak a vanilla Ubuntu install with…read more
I’ve decided to join the recent trend of mining cryptocoins with GPUs. First, I got a GPU (an EVGA 1070) to complement my 970 and stuck it in my desktop. This is nowhere near profitable because I’d have to block an I7 machine to mine on 2 cards, and also get annoyed because I can’t use it. also, rather than my previous attempt few years back using a couple of cards stuck in a desktop PC and having all family complaining of the noise, I’ve decided to build a proper…read more
I’ve decided to put in a knob to control the volume directly on the box itself. It will be controlled by volumio itself via a plugin, much like the GPIO Buttons plugin. Since this is really a development kit approach, the hardware consists of: A KY-040 rotary encoder and A screw-based prototype board Both are relatively easy and cheap to find and buy. Rotary encoder The encoder is straight-forward cheap version, with a push button too, just in case. It’s even mounted on a PCB and has pins too, so…read more
A while ago I’ve decided to try my hand at replacing my Sonos system with a DIY version of a sound system. I have two reasons to do this: I think it’s going to be fun and I have a bunch of FLAC files at odd resolutions which are not really playable by the Sonos system. After giving it some thought, I’ve settled on the following configuration: A Raspberry Pi A sound card for the Raspberry Pi. For starters I’ll be going with a Chinese clone An amplifier A couple…read more
The past few days I’ve been struggling with the unknown of how many pins from the GPIO interface are actually used by the HifiBerry sound card (or my clone). Fortunately, I’ve found the used pins: As you can see, there are quite a few pins left for other things, which means I won’t have to use an arduino to control things anymore :) HTH, A little experiment: If you find this post and ad below useful, please check the ad out :-)
My stable configuration file for Volumio looks like this now: Basics:
|
1 2 3 4 5 |
initramfs volumio.initrd gpu_mem=16 max_usb_current=1 disable_splash=1 |
Sound card:
|
1 2 3 4 5 |
dtparam=audio=on dtparam=i2c_arm=on dtoverlay=hifiberry-dacplus dtoverlay=lirc-rpi:gpio_in_pin=26 |
WaveShare screen:
|
1 2 3 4 5 6 |
max_usb_current=1 hdmi_group=2 hdmi_mode=87 hdmi_cvt 1024 600 60 6 0 0 0 hdmi_drive=1 |
Network:
|
1 2 3 4 5 6 7 8 9 10 11 12 |
auto lo iface lo inet loopback allow-hotplug eth0 iface eth0 inet dhcp allow-hotplug wlan0 iface wlan0 inet manual wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf post-up ifdown eth0 iface default inet dhcp |
The only more convoluted configuration is the networking, which allows me to connect to my wireless network. Once the setup will be stabilised, I will be able to connect it via ethernet, making the whole last section obsolete. And the wpa_supplicant.conf file looks like:
|
1 2 3 4 5 6 7 8 9 10 11 |
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 network={ ssid="ssid" psk="passphrase" id_str="Home" proto=RSN key_mgmt=WPA-PSK pairwise=CCMP } |

The other day I’ve got a Chinese clone of HiFiBerry, a PiFi DAC+ v2.0: Here are the steps to configure it with Volumio. First, you need to install Volumio 2 (2.129 at the moment of writing). You need to configure it to e.g. connect to the network, index songs. Note: Back up your config.txt (and wpa_supplicant.conf) Once you’ve got it up and running, select the Playback menu: … and select the Hifibetty DAC Plus for the Output Device and *DAC Model. Make sure you enable I2S DAC: For the options,…read more
TL;DR: My solution was to just set the DVMT (Dynamic Video Memory Technology) to 64M. YMMV though… Yesterday I decided I want to start building a hackintosh to replace my old mac mini. My system has the following components: Asus Maximus Hero VIII Alpha 16 GB of RAM I6700k Some SSDs, HDDs and a NVMe I chose not to get a graphics card since the nice ones are both expensive (600+ for a GTX1080) and unsupported (there are reports of RX480 working-ish). So, for the time being I’m stuck with…read more
