Yeah but if you got 10A out of one of those bricks it'd be because there was something terribly wrong with this miner. The Vcore buck would peg out at around 65 watts output.

That one-blade S9 is basically a 400W S7.

Actually 275MHz makes a theoretical max of 121GH. It might be pushed further, and I'm considering upping the max voltage, but the ~3.1V/275MHz is about the peak hashrate from 60W DC. But there's no good reason to limit it to 5A brick power since some people have 8A bricks or PCIe PSUs. The stock fans and heatsink will only handle so much heat, but the final version has a temp sensor and overtemp shutdown for that reason.

275MHz ran stable overnight. I restarted it this morning on its own worker for ease of tracking.

Yes you would. The driver's the same, and 2Pac and Terminus have different speed flags.

(I just thought it especially funny that a guy called "the searcher" would ask such an obviously easy question without searching to see if it had already been answered a hundred times. I like to help people, but mostly people who at least try to help themselves first.)

275MHz/121GH, 12V 4.9A from top core voltage. Let's see how long it runs stable. That looks to be top speed off a 60W brick, unless it'll run stable at 300MHz at a bit lower voltage. Which should be doable, but it'd help to have the auto-reset firmware on there. Which my firmware guy says will be ready in a couple days.

That's good, because PCBs are already on order.

Well you know, someone could organize a group buy.

Is SHA3 mathematically identical to Bitcoin's algorithm?

That wert, art and evermore shall be the answer to every question of the form "Can you mine xxx with this?" And henceforth that question will never again be answered except in this extremely sarcastic manner.

GPUs have been irrelevant in BITCOIN mining for four years. You've already given that advice in this thread and it's still just as irrelevant.

The only part that's not relatively straightforward is the ASIC itself. Let someone with millions of dollars do that part, then talk him into selling you some. And then make a miner around 'em. It's not too bad if you have a background in electrical and computer engineering and a good programmer or two at your disposal.

Well that's good. The options were either some kind of multipool or some kind of scam, good to know it's the former.

The stick has a 10K pot on it, which gives you about 1.2 to 1.6 volts. The buck driver is good up to 2V and if you can supply it with enough power without ruining the USB jack, the circuit should output up to 17A.

Cool, you created new ASICs built for other algorithms and made them both signal- and pin-compatible with the BM1384 and then swapped them onto the stick and got it working? I bet that was difficult.

I gave him an F not for not understanding the formula, but for sucking at algebra. Dropping variables, losing signs, not terribly encouraging.

If you want to know what Resistance sets a particular Voltage, you wind up with R as a function of V. So the formula was R as a function of V. That's 8th grade level stuff. It's part of my character to not do people's homework for them; if you ask me for help I'll help you but I won't do all the work for you.

Spot on.

My inner teacher says, "F".

Also I forgot to specify, this gives the answer in Kohm. But that doesn't change your grade.

R=(9.8V-12.4)/(2-V)

No it wasn't hard, but I could have sworn I saw someone discussing that earlier this month. I didn't find it when I went looking, in both this and the Compac thread, so either the post got deleted, or I dreamed the whole thing, or there's somehow another thread folks talk about how to use these sticks? Someone was asking about exactly what you're asking about and was advised to use the --usb flag to limit the number of sticks per instance so he could divide them up into high and low spec sticks. Within the last couple weeks.

Although I do like that it's mentioned in the first post. The answer to at least half of people's questions is "read the first post".

Couple corrections - Compaq is a defunct PC manufacturer, and the S5 used BM1384; BM1382 was the S3's chip.
