Hi everyone!

Would someone please post what speeds and settings they used to get 1TH/s on the r606?

Also if I was to buy a second one, could my rasberry pi run two or more r606s or would I have to get another pi?

Thanks!

Sam pretty much covered the 1TH/s speeds. As for the Raspberry Pi it really depends on which one you are using. I have not tested a Raspberry Pi 4 yet (I receive a 2gb ram version this coming Tuesday 7/30/19 so will be testing soon) however the Raspberry Pi 3 b+ and older units, the gigabyte lan and USB ports all share the same (one) USB Bus. Which really limits what you can do with the Pi 3 b+ etc. I was running 4 Newpacs and 2 R606 on a Pi 3 b+ and the R606 no matter the Mhz and voltage they would not go over 500 - 550 Mhz if I was lucky. The system would detune and average about 650 to 750 Gh/s each. Switching to a dedicated desktop running Linux Mint (just another flavor of ubuntu) and from here I have been able to maintain average speeds of about 900 - 950 Gh/s each.

I do not know why the Pi developers decided to make the Pi 3 and Pi 3b+ all run off one usb Bus. As it becomes a huge bottleneck when you have more devices being used. I originally ordered a Odroid XU4 to replace my Pi 3 b+ however UPS lost my package, so got a refund and picked up the Pi 4 to tinker with instead. I have 2 test projects I am wanting to run on the Pi 4. 1st running these miners as I would like something that uses little wattage and can control the miners, as my Linux box is a power hungry FX-8350. I'm wanting to set this box aside to running Handbrake on media files and use 3D apps to design models for 3D Printing projects. 2nd test project is as a NAS. I'm now using my Raspberry Pi 3 b+ as a small NAS unit with 1TB of total space. Does ok but transfer rates on the network is hitting 12 - 18 MB/s. Again another weak link of the Pi 3 series. So wanting to test the transfer rates out on the Pi 4 since it's now using 3.0 USB ports and also use multiple buses now, no longer combining all usb ports and networking to one bus.

Fun times.

Update. For those new to linux, please take some time to look over some free courses from Udemy. I use this site extensively for both paid and free content. I'm a programmer on IBM I series / Power 9 (running os/400) machines and always love expanding my knowledge in Tech. This site is a pretty useful tool. And there are also courses in regards to the Block chain, bitcoin etc. So not really and AD for Udemy, however they help me out quite a bit so passing on the knowledge.
