Is undervolt same thing as underclock?

Undervolting is changing the voltage to a lower voltage. Since power used is based off the square of the voltage, a small change in volatge can mean big power savings.  But of course it can't run as fast.

Underclocking means turning down the speed (clock speed) that the miner runs at.  This can be done usually without touching the voltage.  Typically most people try to run the fastest clock as the lowest possible voltage needed to get them to the desired clock.
In other words they both are ways to increase electrical efficiency of the machines while reducing overall hashrate.

Undervolting will significantly increase the efficiency per watt, you may not necessarily see a decrease in hashrate.

Underclocking will significantly decrease the hashrate, you may not necessarily see a increase in efficiency.
If undervolting would not necessarily decrease the hashrate then why would everyone not do this to increase profitability?

When a retailer like Intel ships a CPU, it has been tested to see what is the minimum power need to run at a certain speed (part of the binning process).  They bump up the power used by the chip just to ensure stability.  A lot of people who are enthusiasts run at stock speed and just lower the voltage.  If you don't like tweaking, Intel sells variants like the 3470S which is a low power version of the 3470 which they have tested to be able to run lower voltage and be stable.

Most miner companies will bump up the power just for stability in higher temp areas.
If using a lower voltage is less stable, wouldn't that mean that the average hashrate (over 1 day, for example) would be lower, while the shorter term hashrate would be the same as not undervolting?

Hashrate would be lower if the voltage is not adequate for performing the compute function without error.  For computers, people use burn in tests like Pi-24 or Prime to confirm the system is stable.  For a miner you could just keep dropping the voltage until it becomes unstable, then raise it a little to guarantee stability.

End users have time to do this, typically companies  don't.

That doesn't make sense. If you limit the voltage, doesn't it automatically decrease in hashrate? Anyway, I'm going to do both to see if there is any difference

Not necessarily.  See my post above.  The i5-3470 and the i5-3470S that Intel sells are more or less the same CPU, just Intel had a higher quality on the 3470S chips and bins them as such.

Since each miner's chip is different, you have to trial and error.

★☆★ 777Coin - The Exciting Bitco
Looks like it will run at a loss in a month or two, at least for people like me who pays $0.20 / kWh.

What then? There should be people around with super cheap electricity who can squeeze a few hundred bucks out of it. But I don't know where/how to sell and what the price shipping will be (Im not in the US).

Using it for heating is an option. But then I need to underclock and get a more silent fan. All those cables etc won't look nice either.

What are your plans?


You could always shut them down and hold onto them in the hopes that bitcoin price will rise faster than difficulty (it likely won't).  Otherwise, your much better off just selling them now and getting what you can for them.  ASIC hardware depreciates quicker faster than pretty much any other hardware on earth that I'm aware of.

I Quantum Leap to different worlds when I sleep...
If your a Gambling man?I would undervolt it and try too SOLO Mine with it @ http://bitsolo.net using it in a pool setting actually gives you a fighting chance too actually find a block since your working off the pool's Nonce's instead of Solo mining on your own Nonce's which is most likely not going to cut it at this hashrate.
I believe the S1's are one of the few older newer machines that  can actually solve a block these days? Many of the older machines I don't believe have the NONCE using capacity too even find a share in the BILLIONS? Like Block Eruptors and USB sticks I think they completely lack the technology and Nonce using capabilities and will never find a block at these levels and going forward?I could be wrong? But I have yet too see any proof that they are even capable? and have read many of the older machines are limited with the NONCE'S they can use and apply to solving a block. But the S1 has proven already it can find a share in the Billions unlike the others like this  https://bitcointalksearch.org/topic/m.6247114.
 It's a long shot still but with a real possibility I would think better odds then any STATE lottery? and Hey worth a Gamble for 25 Bitcoins for a small price of electricity undervolted the payoff could be big Wink That's what I'm going to do Grin

if someone wants to sell antminer at decent price i am interested to buy.. just pm me .. escrow can be accpeted but you pay the fees.. Smiley
where do you live? i'll forward your offer to my friend who want to sell S1 Tongue

Someone should set up a museum of Bitcoin mining hardware. (An online museum would be a good start.) For each unit, show the date introduced, the hash rate, the cost, the profitability, and the date the unit became unprofitable.

It would be cool to have them all in a row - desktop PC, graphics cards, FPGA boards, USB stick devices, the first ASIC-based cards, water cooled racks of ASICs ...

Whatever happened with that "Bitcoin store" that was supposed to open in New York City?

"Bitcoin hash rate will go to the moon!"

Some may argue that the network hashrate is already well past the moon. The numerical rate at which the difficulty is increasing is multiples of the difficulty that was in effect late last year

I think forum user DocZombie has an online museum setup:

https://www.thebitcoinmuseum.com/index.php/

Not sure if there's a Bitcoin store per se in NYC, but there's the NYC Bitcoin Center that's right down the block from the NY Stock Exchange.  They have regular Bitcoin live auctions, get togethers and events, classes, sell Cointerra equipment, and last I heard was adding a Bitcoin ATM pretty soon:
