  1. Yep. Sorry if I came out snarky, guidol's right, it's an easy mistake to make. Still impressed you managed swap the ram chip.
  2. Actually, nothing is wrong. You got exactly what you should expect. The K4B4G1646E-BYMA is a 4 gigabit ram module. BTW: impressive that you can resolder a BGA at home. Congrats.
  3. I'd recommend keeping Kobol's option of the little clear window w/mounting holes on the front panel for the OLED status display.
  4. It's a nice idea if you have all the hardware already and have cheap (school/makerspace/etc) access to a laser cutter. I'd be concerned that you're pushing data for 4 HD's through a usb hub to one of the Pi3's ports, which is also an (internal) usb2 hub... which is shared with the ethernet. The Pi3B+ ethernet can do ~300 mbps if you're not using the USB for anything else. Half that bandwidth will be used pulling data from the disks, so you'll be lucky to get ~150mbps. If you're dead set on a pi, I'd recommend considering the Pi4, as the ethernet is no longer shared on a single USB root port.
  5. And I need to find a way to migrate my current install. I turned 3x 8TB into a 16TB raid-5 BTRFS array, and am somewhere around 8.5-9TB in use. I thought I had a lot of headroom, but if the tools won't work...
  6. Oh <edit: expletive actually deleted>. umm, do you have a source for that?
  7. I wonder if it's more a matter of where are the sensors mounted relative to the fans. The sensors only tell the story at a very specific point in space, after all. The helios board itself is placed in the back half of the enclosure. With reversed (intake) fans, you're blowing external cool air directly on the board. With standard (exhaust) fans, you're pulling internal air that's been preheated by the HD's, across the board.
  8. OrangePi 3 uses the Allwinner H6 chip... and the issue is, basically, AllWinner (deliberately?) messed up the hardware implementation. From the wiki: http://linux-sunxi.org/Linux_mainlining_effort#Status_Matrix
  9. Yeah, no tracking number here either. My order just appeared via local courier on Monday. They said they'd have an OS image up by (last) Wednesday, but nothing yet.
  10. FYI, the Kickstarter rewards are starting to arrive.
  11. 5.1 RC4 just landed. The release notes have all been pretty calm, so I'm going to guess it'll only go to RC7 Figure 3 more weeks for 5.1, a 2 week merge window, and potentially 8 weeks for 5.2... so ~3 months puts us end of June / beginning of July
  12. heh, sorry, I mean that the neo2 has no wifi. It's a ethernet-only board, and (without breaking out the pin header) only one usb-A port soldered. The neo plus 2 might be closer to what you're looking for, but it's not a board I have. Should be very, very similar in performance though.
  13. Sorry, I missed the part about where you need wifi. In that case, I really can't recommend it unless you're using a USB dongle with proper antenna.
  14. I'm running wireguard on a pair of nanopi neo2's, and iperf is giving me >200mbps throughput at ~40% load
  15. I think you're looking for the h3consumption tool that allows/allowed you to turn on/off various peripheral support to control power usage. The issue isn't that it's tied to the version of userspace (eg. stretch), but rather that it only worked with the legacy (3.4.x) kernel
