The fan rpm is a good indicator, my guess would be "silent" in mining terms ;P

The VRMs shouldn't generate that much heat tbh so when you have a efficient way of cooling them they should run quite cool, a few watts can easily create a 100C hotspot if there's no efficient way for it to dissipate.

Such a teaser, I want to see that S3 naked :<

Let's change PoW so that anyone with moderate amount of capital can attack us, sounds like a great idea! Both cpu and gpu minable chains would be an easy target at this point when the economic target is as big and hated? as BTC. You sit here and worry about BU miners trying to kill a minority chain in case of a fork and want to trade that for gpu miners (who many are heavily invested into alt coins) and/or bot net owners. I guess the BU miners wouldn't mind since they would win by default when the core chain self destructs on a new PoW.


If you want some tinfoil this is how I would take over BTC on a budget and couldn't just 51% the current network due to my inability/unwillingness to spend the needed funds.

- Get cosy with lead devs.
- Push for PoW change to something supposedly ASIC resistant.
- Develop ASIC solution in advance for when switch happens (can be on shit node and somewhat low cost, use mining profits to jump to bleeding edge asap later) This would cost a fraction of what building hardware to try and take over current network by building hardware (more than factor of 10-20x). This might even be within reach of a wealthy early adopter *hint*, a couple of mil is enough to do a mass rollout on say 65/40 nm.
- Easily keep CPU/GPU miners at bay due to them being unprofitable, doesn't even make it apparent anything strange is going on (someone just have cheaper power and more cards duh!)
- Reap majority of all block rewards.
- Stay cosy with the devs and push for any and all changes you want to do, congrats you now own the network without anyone the wiser.
- Even if competition starts developing their own ASICs its something that takes months to get working hardware out of and even longer to mass produce.

So I guess Bitmain decided to not learn from BFL then, trying to go cheap on PSUs meant for 24/7 operation with close to 100% load is not the brightest idea.

One order I got was labeled as "PC GAME" and got slapped with another 10% import duty due to their sloppiness, also had problems due to them not stating a shipping cost and inaccurate weight. The problem with writing "Bitcoin miner" is that it's not a recognized customs category for goods and 99% of customs worker wont know in what category to put it (hence delays and complications)

Meanwhile labeling a shipment of chocolate chip cookies as chocolate chip cookies is not by the customs standards either, but then 99%+ of all customs workers can figure out what category it belongs to.

TBH, Intel is barely making stuff on 14nm ;P

Someone needs to work on their math skills, if one ant is unprofitable then 1000 of them will be as well as long as the cost of running them /ant stays the same.

what's the dip switch used for?

You could probably find some cheaper design alternatives at those loads however, remember they only used half the VRMs for most of the October units. Then again why would anyone bother trying to get these on boards even if they were given the chips for free, considering the hardware will be obsolete by the time you have something working. Wouldn't mind one for a key chain though!

Got my October Jupiter running at 535GH/s@550W (at the wall) for the last 2 months

Or the neptune chip is pin compatible.

if 100GH/s@1W/GHs is worthless on the 20th of sept then the S3 is almost as worthless as well, might just skip buying hardware altogether then!

Not to mention you are throwing away 105-110~GH/s@1W/GHs per ant that you upgrade if you were under-volting. So for 0,46BT what you get is
a 350GH/s@250W upgrade compared to just keeping the S1, might as well just buy a S3+ instead.

The "smartphone" era is far away in the future for crypto, we have barely evolved away from this

I guess some poor employe at Bitmain turned them the wrong direction after being kept awake for a week straight assembling 100xx ants. As long as both of them are mounted "wrongly" it should be just fine.

From my testing they don't seem to show this behavior if you keep them cold, and I mean cold. I stuck a unit that would do 250 for 1-2h and then started falling in performance in front of a portable AC and got the load temps below 25C, it seemed to be just fine at 495GH/s+ under those temps (12h~ of testing) but not really worth it with the AC costs ;P

Or maybe it's just random behavior and it will drop the has hash rate despite the cooling given enough time, someone will figure these out eventually :/

Make sure to keep that beast cool (sub 35C pref), they really don't like getting warm when you run them at 237/250MHz (hash rate starts dropping and you might get and x or two after 10h+ of running)

CPU performance scaling is limited by other factors than just process node, if you want to compare performance progression over node history take a look at GPUs since they are more similar to mining gear (can just add more cores for improved performance so much better scaling with node shrinks). Beside Ivy and Haswell are both on 22nm and Intel was mainly focusing on performance/w and GPU performance.
