The other mistake is, where did you conjure up cgminer 3.7.2? Why would a cgminer version about four years old work with hardware designed last year?

You can find the appropriate version by...

drum roll...

reading the first post!

Note how, in the run syntax, it gives you a sample command line to start. You edit this with your own pool configs. Note also the --suggest-diff parameter. Then note that setting frequency is --gekko-2pac-freq; does it look a bit familiar? Try adding that to your command line but change the number.

And if it still doesn't work, go read a tutorial on command line interface and try again.

Like I've been saying for over a year now, the answer to just almost every question ever asked in this thread is "read the first post".

It is a silly question, unless you're consulting the 2Pac Support Thread.

Nothing about this Terminus is working as well as I had hoped. To be frank, that includes the power brick. I'd hoped by going overspec on the current it'd be able to handle a little better but they're kinda junk. Soon as I have time I'll be tracking down a source for better, and then I reckon if someone's brick sucks it can be returned for an improved replacement.

I guess the "silver lining" is, all these kinks should already be worked out by the time I have a newer better pod available one of these days.

Alright, now factor into that the average cost of 1TH. Four years ago 1TH cost a couple thousand bucks, now it's about $100. I bet the graph gets a lot flatter if you normalize against that.

Too bad searching FAQ section of the first post for "OFF" or "voltage" doesn't turn up references to an illustrated graphical guide to setting the voltage. Also too bad there aren't charts in the first post that give you suggested voltages (and expected current draws) for given frequencies like 250MHz and 150MHz.

The answer to just almost every question ever asked in this thread is "read the first post".

...uh, what?

Is there a way to search for answers to what are likely common problems asked anytime in the 14-month history of this thread?

Yes there is.

A way to search for answers, I mean.

For your question, no you pretty much have to pull the stick. Might be possible if you know which points on the board to short across and jump-start the string, but it'd only work right under certain conditions. Best to just pull the stick and re-insert.

That's great, but tech support doesn't really care. Maybe you should mention it in the sales board.

That's not very many errors. If you think of it as a percentage of accepted shares (all of which are in the neighborhood of 5.3 million) and also as accumulation over 3 full days, it's almost trivial.

From a hashrate perspective, yeah. However, the power systems within the miners are different. The 2Pac has 2 chips in series so the main regulator has to double the voltage but not the current. This means the regulator, which is rated for around 17A, can push the chips well above 400MHz if you can keep them cool. The Terminus is 8 chips in series pairs, so it runs four times the voltage and double the current. The main regulator is limited to 20A, which means 10A per chip, hence why it can't hit the higher speeds like a 2Pac can.

I could have made it faster by adding in more series pairs, which increases the voltage but not the current. The practical top-end here is about 7 pairs (limited by the regulator's maximum output voltage). Adding more chips would require a larger board, larger heatsink, more fans and make the whole thing more expensive. The practical limit for this size miner is 8, maybe 10 chips.

Before shipping out, every Terminus pod is run for 1 hour at max voltage and 200MHz.

On the next one I'll be using a custom main regulator that should be good for more power, and of course it'll have more efficient chips so a much higher hashrate will be attainable. Also it'll integrate software voltage adjustment so people who don't have meters and screwdrivers (which is to say, lame people) can still do the tweaking.

Product-specific questions should probably be addressed to the support thread, now that a product-specific support thread is available.

From the Q/A section of the first post of the Terminus Support Thread:


The "more details" link above gives us:

USB2 or USB3?

Not sure I've come across that one. Not even keyboards or thumbdrives?

The instructions in the first post are about as simple as it gets.

What errors are you seeing?

If it's because of -O2 I'm gonna laugh because I've lost count of how many times someone has made that mistake.

Is it a good enough hint that this is posted in the Bitcoin section?

The error, and to a certain extent its solution, is here:


I bet if you look into cgminer's included README file for that error you'll find some advice.

Or you could check the FAQ section, which includes this little tidbit:

That's one of the small-order price breaks available when ordering direct from laura@gekkoscience.com

The "make -j 2" line is where it compiles the program. Once that line runs, your terminal should be pointing to the folder where cgminer was compiled.

After that, you run the "./cgminer -o"whateverelse line like under the "How to Run" part of the post. With your pool configs instead of the sample ones.

If you're following the directions and somewhere you think you're required to click on something with a mouse, you're probably doing something wrong.

Also what you're doing is not coding, has very little to do with coding, so coding knowledge is mostly irrelevant. What you want to learn is how to navigate a Unix/Linux terminal. Basically equivalent to DOS shell in Windows, just a whole lot better.
