content: So I'm trying to buy a bunch of Orange Pi One'shttp://www.aliexpress.com/store/product/Orange-Pi-One-ubuntu-linux-and-android-mini-PC-Beyond-and-Compatible-with-Raspberry-Pi-2/1553371_32603308880.htmlHave tried two credit cards (VISA + Mastercard) and both have been declined for "security" reasons.Anyone else had this issue? I haven't encountered it before.Anywhere else I can buy the Orange Pi One?

content: I had been wanting to try this, so I just ordered two. First attempt and the purchase failed saying "the card does not support the currency". Odd since the price was in Australian dollars and I was using an Australian card. About 10 minutes later, I tried to pay again and the purchase went through.Richard

content: You saw that new one with the Wifi connector? Maybe get that one. The one single USB port on the $10 one with Ethernet is annoying.Also, HMDI support on these things is not great. Maybe I'm doing it wrong, but as near as I can tell you need a specific script.bin for each mode. 1080p is one script.bin, 720p is another. HDMI to DVI is still another.They are cheap though!

content: Is this for your SETI farm Dave?I have about 10 x RPi2 here (repaired ones from TopLoser) that I might press into service in an old PC case with an old 10/100 switch/router and an old WiFi connection.I've also got a <new> domestic solar panel (37v, 250W) - I might make it a solar powered search for ETI. Powered by a star, that's got a nice sound to it.

content: Quote from: EEVblog on May 10, 2016, 02:26:05 amInteresting, I'm curious how well it will perform. I had seti@home running on a couple rack mount servers, pretty grunty processors, but sadly seti@home is more gpu dependent, and even a mid range laptop gpu could have outdone the 800w of servers I had running it.

content: Quote from: EEVblog on May 10, 2016, 02:26:05 amI know these Orange Pi's cost bugger all but wouldn't their very little work output actually make them terribly inefficient?Wouldn't it be cheaper to use a GPU instead at least work done per Wh of power used.There will be a few cheap secondhand nvidia cards in the next 2-3 months with 100's of times more power than a couple of Pi's

content: Quote from: v81 on May 10, 2016, 06:53:56 amThat's pretty much the issue I encountered with my setup too. I had two dual core 3.2ghz xeons, and another 3ghz Pentium running seti@home, and compared to a really crappy gpu it still sucked lolThey would use a whole lot less power though, and I suppose if you are someone like dave, a couple hundred bucks to try something out likely won't make much of an impact on your bank account, plus he can always switch to a gpu later and repurpose the pi's.

content: Quote from: XOIIO on May 10, 2016, 07:05:37 amThe xxx Pi's would certainly use a lot less power, but the power to work output ratio is where it's at.As you said even a single crappy GPU smashes multiple x86 CPUs for performance per watt.Same applies to the PI's (this is assuming the xxx Pi is doing the work and not offloading the it to another device (ie like the ASIC bitcoin miners)I have several PI's and love them, they're just not the right tool for this job.People are running PI clusters for SETI and other distributed computing tasks.This is great for learning about Linux and distributed computing, and if this is Daves goal he should continue with chasing up some cheap pi's.However if Dave, or anyone for that matter actually wants to contribute then a GPU is the only practical solution.Setup is faster and easier too.

content: I've run SET@home on my dual processor Xeon with grunty Radeon R9 card, and also my 3770K with another decent GPU.Yes is chews through the work, but the GPU only shows up as one processor out of the 8 or whatever working on one task. It is faster than the other GPU tasks, but not orders of magnitude.

content: Quote from: EEVblog on May 10, 2016, 11:32:51 amI guess what i was trying to gently say is thatunlessSETI have some magic voodoo it is common knowledge among the distributed computing community that what you're trying to do is stupid and incredibly inefficient.Using pi's or similar is a great way to get a feel for setting up and running a cluster, if this is what you intended, stick with it.If you want practical and efficient results us a GPU, i'm a little out of date re SETI and several gen old video cards, so the other forume members can correct me, but i suspect an nvidia GTX780 might be a good starting point around $100People have done isbecause they canand that's about it.As mentioned above the nvidia Pascal cards were announced a few days ago with a global release on the GTX1080 in the last week of this month.As also mentioned all those whom are super keen will drop their previous gen cards.

content: Quote from: EEVblog on May 10, 2016, 11:37:16 amThe work units give to a GPU are packaged differently to those given to a CPU, also each processor is structured differently.Also the GPU does not reveal each of its internal parallel units like the cores in an individual CPU package.What you should be finding is that the R9 card (assuming it is something middle of the range or better) will be drawing the same or less power than the pair of Xeons and comfortably crunching the GPU specific.Please forgive the rushed nature of these posts and lack of links to supporting data as i need to head to the airport.I love SETI and F@H but my previous research says dont run it on a CPU, too inefficient.I too love the raspery Pi, and the excellent cousins of it that have popped up, have previously read articls re dist computing on them, can be done, not efficient, pity i don't have a link i can throw.Checkout the distributed computing forum on overclockers.com.au for more info, or simply post a thread there asking how to get the best bang/$ for SETIAlso on the side, by chance is the Xeon a dual socket 2011 machine?Facebook recently let go of some server gear and there are Xeon E5-2670's going on ebay for ~ $100 each.8 physical cores per CPU + hyperthreading and 20MB of cacheCould be a cheap upgrade if your board is compatible?Gotta run, will read with interest in a day or so.

It lets you store money in A$, US$, NZ$, Euros and British Pounds, so you can play the exchange rates a bit when buying from overseas. Handy when you want to lock in a price when the Aussie dollar is falling and transactions show up immediately on the website for the card. I have used it in the past with Aliexpress without any problem.

content: Apparently, IP address is one of the reasons for declining a credit card. It can either be because the IP address is on a fraud list or sometimes they check if the IP address matches the country. If you are using a VPN to connect to the Internet, that can definitely cause this problem. With the shortage of IPV4 addresses in Australia, perhaps some hosts are getting overseas IPs.

The HDMI-DVI issues came from the forced on HDCP in default builds by orange pi (no copy protection information on hdmi port, no image).
