"starving" what now? Whatever it is you're thinking is likely not the case. They're all tested at 200MHz stable for at least 1 hour before I ship them.

Each node has a small testpad for measuring voltage. The voltage between ground and Vc3 will give you the full string voltage, or you can measure across Vc pads to get node voltages.

It could be that the brick is garbage. If you can power it off a known reliable 12V source and the resets go away, let me know and I'll send you a replacement brick.

Let it be known, I'm pretty disappointed with the bricks I bought. 200MHz draws about 3.4 amps, and these are 6A bricks but still crap out to often. I'll be getting better ones in the future.

The voltage knob works just like a volume knob, or the knob on the 2Pac. Clockwise means higher.

They're getting choked out somewhere. That's about the speed one would expect from 200MHz. Try setting them at 200MHz and see if it stays about the same or goes down.

My guess is, you'd have to divide them amongst two controllers or something in order to get full throughput (and about 107GH) to all devices.

Do a bit of searching. That question has been asked and answered more times than I care to think about, even spawning at least one entire thread on the subject. Since I don't run them for fun I don't have any actual recommendations. Also since I'm a cheapskate with skills, so when I need something I just go make it (or in this case, "upgrade" an $8 eBay hub).

By the way - an update regarding changes to the Terminus sales process.

So, announcement.

Terminus pods are still available and in stock. 2Pacs and power supply boards (both DPS800/Common-Slot and Dell 750W) are also in stock.

However, starting here directly, Laura will no longer be acting as a sales rep.

That job, though mutually beneficial, was created for her in order to help meet her needs. She's recently found a great job doing what she loves so the necessity is no longer present, and that job is taking up a fair amount of time and energy so she's no longer able to keep up with the flood of emails.

If you started an order with Laura, she'll see it through to the end. But any new orders need to go through sales@gekkoscience.com instead.

Laura gladly took on and handled well what I consider to be the worst part of business, so if you get the chance to drop her a line, make sure you say thanks for all her work and wish her good luck in the future.

That's what I figured. It started mining at 100 (the stock setting) then ramped up, and once power got too high something dropped out. Now you need to figure out if the limitation is your core voltage setting or the USB port.

Check the first post, specifically the power charts. I'll bet that'll give you at least a hit toward what's the problem.

Yep, my test setups drop out a lot with the same type errors. Kinda surprised me the first time, since I had one pod running on a clean build for a couple weeks without any trouble.

Yes, it's a hardware issue and needs warranty repair.

Speaking of which, everyone who's sent pods back for repair, they're fixed and being tested and will be return-shipped no later than Friday.

I don't think suggest-diff will have any effect on traffic between cgminer and the miner itself. That only changes the threshold for returned shares to the pool.

I asked Eyeboot about it, he's gonna send me some samples to play with. He says they aren't as good, won't clock up as high.

No, bare PCBs.

There's a rough picture of the topside of the circuit board on Eyeboot. Looks a lot like they changed the layout and a few parts but it appears to be roughly 95% 2Pac. Different 1.8V LDO but the same PLL source divider. It's got level shifters which means it's a 2-chip, and they even copied my clock line shifter (which is different from how Bitmain does it).

If VH's driver isn't friendly with 'em, I guess at least that means they didn't steal my CP2102 product strings.

Wow, that looks quite suspiciously like a ripoff of my design. A few parts are different but not, you know, a lot.

The Compac was supported by Icarus driver sometime mid/late 2016 I think, because the original driver was built off the U3 code from Icarus. VH's custom driver for the 2Pac was built specifically for the 2Pac, and made flexible enough to be backward-compatible with the Compac and, with minimal modification, forward-compatible with the 8-chip Terminus pod.

When cgminer 3.7.2 was "current", I wasn't even thinking about making miners let alone had a product on the shelf. So native support for anything of mine by Icarus driver is impossible with that version - with the exception that the single-chip Compac might technically work if cgminer thinks it's a really slow Antminer U3.

Test boards arrived this morning.

I got plenty, and you know how to get 'em.

I've never successfully run one above 275MHz, and I built the thing. 300MHz, unless you get lucky with the chips and can tweak the voltage down (or keep that regulator module cold), is probably unattainable.

If you see an unexpected drop to 200MHz that means the string locked up and reset, which took the chips back to default speed and cgminer started ramping it back up to your setpoint.

The first thing I consider is that people aren't so great. That assumption is usually valid. I mean statistically, half of people are below average. Maybe the first post instructions aren't so great, but maybe it's because they assume a basic competence that apparently a whole lot of people are lacking.

*.7z files open with 7zip. That's not difficult to find out. Cgminer 3.7.2 is freaking ancient by crypto standards, so there's no reason to assume it's pre-compiled with the custom driver written several years later. That's also not difficult to find out.

So, what you do is, you download the proper build from the first post. You get 7Zip and open up the 7z file so you can extract its contents. Then you run that command line from earlier, except you use --gekko-2pac-freq because you're running a 2Pac and I bet it'll work.

I reply sarcastically to noobs not because I'm full of myself, but because I'm a really big fan of self-reliance and I hate when people take the easy way out instead of spending the extra five minutes to solve their own problems, especially when the answers are, for the most part, already collected in the first post.



That said - hey VH, you might want to mention in the first post that 7Zip is required for extracting your Windows pre-builts because not everyone recognizes it.
