Hi. Good evening. How are you? So I am having trouble getting the r808 to connect. I have compac f miners too and can get them to run on windows and the raspberry pi. But when it comes to configuration of cgminer vthoang on linux it always fails, the installation. The compac f software on the pi and windows recognizing the r808 but it either goes zombie or off. So now on windows. I tried cgminer 3.7.2 and cgminer 4.12.0, a special one meant for the r808. So set that up today. Using zadig to put the winusb driver and also have the frequency at 25 to start. When it 1st started it kept saying failed usb. It accepted 2 shares and then said off. No matter how many times I restart cgminer it recognizes the r808 but goes straight to off. No white light flashing. Just a solid blue light. I am using my power supply 6 pin connector to power it. So can anyone help with this? A version of cgminer pre compiled that works? I also have evening connected to usb 2.0. No usb 3.0 at all. Any help would be most appreciated. I wish to have the r808 mine solo with my compac f miners. Thank you.

still looking for someone who will do diagnostics and repairs on these. I have one that powers up and the cgminer sees it but it wont hash the lights flash a bit different too.

Hate to toss it and would rather see it get back up and running unless its stupid expensive to fix.

Yes, I think the PSU is good...have tried a few. I do think it is a bad unit. Looking back in this thread I saw that a lot of these were RMA'd and repaired. Was curious what the repair was, and whether any of it was doable by a regular person without specialized equipment.

I'm going to assume you've got a suitable PSU as you seem familiar with gekko products. Only thing I can say is that its a bad unit. Was it sold as working?

Sidehack will have to chime in but I believe the fault is the Vcore regulator feeding the chip. I have a proto of one he sent me that can only run at a low freq.

Hey! Thanks for replying!

I will have to look into the command line detect you mentioned. Tell me a little more about how that could be better than letting cgminer autodetect the r808?

I have also tried this with the new build for the CompacF's (4.12.0) and get the same result...starts out finding zero chips like this:

Off thentop of my head is there a flag for command line to detect the R808? Not sure just throwing it out there. Also have you tried running the new kano-cgminer (see the Gekko Ferrari thread)?

Got my hands on a Terminus R808 v0.4.3...love vintage stuff like this, but having some issues. Getting the "no chips detected/GSE 0 failure, disabling" messages. Tried this on two different RPIs and one Windows machine with a few different hubs and known good PSUs including an HP server PSU. I am able to run Gekkoscience USB sticks on all of the machines, but not the R808.

Voltage across reset pins is 1.42V and every 2 seconds or so voltage goes to zero, then comes back to 1.42V. I think this is the reset loop described up above in this thread.

On CGMINER windows 4.11.1 here's my log:

Any thoughts? What can I do? I appreciate it!

Were you in business when the R808 was around? I'm pretty sure I didn't send you a demo unit. Also pretty sure you're thinking of the R606 but this is the thread for last year's model.

I thought they were 80mm fans? I put a noctua fan on the back end of the demo unit from pre release a while back. Not sure how wide the stock internal fan is though.

There's links one page back.

Of course there is. Embarrassed

It didn't come up in the search and obviously I did not read through this entire thread. Thanks. I'll just order those Cooler Masters from Amazon. I've had good results with Cooler Master fans on some computers I've built, so I'm sure they will do nicely.

I got a bunch sitting in a box if you want replacements. Though really you'd be better off with upgrades. They're a pretty standard 50mm fan. I think someone around here probably posted a listing for better ones than stock.

I tried searching the hardware forum for r808 fan and the only post that came up was your OP on the r808. If anyone still has that listing for the upgrade, please let me know. If not I could buy the ones you have sitting in the box, it doesn't matter too much since I plan on giving it away anyway.

Does anyone know the specifications for the fans or the part number? My fans died and I put an old cpu fan sitting there but it doesn't work as well and I have to reduce frequency. I know it's not worth buying the fans just to run this thing, but I'm giving it to a teenager for a project and I at least wanted to have the fans working for him.

Hi,

i have a issue with my Terminus R808.

I tried to connect to my RASPBERRY PI 3B+. But i can't receive a signal from the Terminus.
The blue light is on.
Also i tried to connect to Win PC. Also no signal.

My New Pac works great with both plattforms.

I hope you can help me.

Which USB connection on the R808 are you using for the communications? The mini USB is for controller communications, the 'regular' (rectangular) USB provides 5V power, no data communications.

With how Bitmain distributes work to its chips, timing is very particular to keep the buffers filled and it only gets worse with higher hashrates and more devices. Different chips have different internal work buffering mechanisms, and the particulars of ASICBoost also change that dynamic, so non-AB Bitmain with multiple chips is pretty much a worst-case scenario for timing requirements. Barring unforseen disaster, I likely won't be using their chips again in the future. Leastways not anytime soon.

If you can get ASICBoost working on your NewPac setup, the timing is relaxed by about 3/4 on them. That means if you can handle two R808 on a Pi, you should be able to handle about three times the hashrate worth of NewPacs. Should be able, I haven't fully tested that exact setup yet.

I think that's an issue I ran into earlier when I was trying to run all 4 of my pods off a pi. Never could get it working and I had to split it between 2 Pi's.

Anyone know if there is a way to figure out bandwith from both internet usage (I use a wireless connection) and USB traffic to calculate where I would get into trouble? I don't like doing it by trial and error and realizing I have to buy new equipment halfway through.
