Why? Isn't it better to include PSU? Its more neat

1) You can quickly replace the PSU at your local shop if something go wrong with it, without necessity to send it back to China and so on;
2) Shipping cost usually depends directly on the weight of the package, and good qualitative PSU weighs several kg (2.3 for Corsair AX1200i).

Very likely that these are two main reasons. Wink

Thank you so much for the time you've invested to make the S4 more funtional, ckolivas. I'm going to send you a donation tomorrow morning.

I'd like to try ck's new version tomorrow, but I have no idea how to go about updating cgminer. Can anyone shed some light, or point me towards a guide?

Assuming your S4's IP address was say 192.168.1.99:

Code:

ssh -l root 192.168.1.99 (or equivalent with putty)
wget http://ck.kolivas.org/apps/cgminer/antminer/s4/4.6.1-141018/cgminer
mv /usr/bin/cgminer /usr/bin/cgminer.bak
chmod +x cgminer
mv cgminer /usr/bin/cgminer
/etc/init.d/cgminer.sh restart

I think that might not keep across a power cycle though.

Since I'm not packaging firmware as such, I've submitted just the necessary changes so that bitmain can include them if they wish (which I hope they do). To be merged back into mainline cgminer would require far more effort than I'm currently willing to put in, and new firmware will benefit the most s4 users fastest.

It is obvious that the miner should be shipped to buyers without PSU. But it wasn't so obvious for Bitmain when they were developing S4... Why?..

Here's another binary for S4 owners
http://ck.kolivas.org/apps/cgminer/antminer/s4/4.6.1-141018/cgminer

This one works a heck of a lot better on pools that wouldn't work previously, and slightly better on the rest.

Great effort. I sent you a small donation and I don't even own an S4 Grin

On the other hand I think 95% of my rigs run cgminer or clones, so there's that. Much appreciated.

I agree - the Sp10 was horrifyingly loud even at 40% fan speeds. however, if you are able to operate without noise limits they are the best machines for build quality, reliability, and setup.

The part I most disagreed with was it didn't have to be that way, at 40% fans most of the noise was made by the PSU and not the actual miner. Same with the SP30, its exceptionally loud because of the PSUs primarily, which is as a result of them aggressively minimising their products.

i think its more an issue of the PSU - because it requires 40mm fans for its form factor. In the SP30 it would be nice if they used a single PSu with 80mm fan instead of a pair with small fans. would make a huge difference.

IMO thats why the S2 is great, those 140mm fans push lots of air even at slow speed and low noise

Honestly, miner manufacturers should just have us buy our own PSU's and avoid all the issues of fires, cables, CE markings, customs issues, not to mention the extra weight to ship it out. If they want to recommend a PSU and provide a spot in the case for it, so it can be racked properly (For those units designed for racks) great. But stop with the wholesale PSU market, somebody is going to die before too long and that's the last thing we need in the Bitcoin negative news of the week. Just one man's opinion.

Integrated PSU can be a very good option if it is a decent psu and particularly if the miner and psu work well together.

Look at the spondoolies gear for an example - the miner website can tell you the voltage, wattage draw, and many other helpful details about how the psu is operating, and the slim psu being built in makes the spondoolies hardware the absolute best for plug-and-play.

Messing with external psus and wiring can get crazy. A clean solution is the key.

Lets be honest, of everything they do well, PSUs are not one of them. They're so loud that they exclude themselves from any inhabited buildings, where as if they went to a larger formfactor and could use ATX PSUs there wouldn't be that problem.

Did you see the video I posted?

This wasn't a burnt smell only. visible smoke billowing and this was after it had calmed down a bit.

Not to lessen the severity of this issue but that is normal for power electronics. The volume released can be rather impressive. Once released the Majik Smoke (and smell) from popped caps and/or burnt circuit boards lingers for quite a while. The smell in the rack case will last days... Point is any actual fire is wholly contained within the psu case and miner case. Once the power is cut from circuits burning open/circuit breakers opening any actual fire ceases leaving only lingering memories.

Hi... For those using the batch 1 PSUs the burning down thing is a real risk. I just avoided a near catastrophic disaster. The miner wasn't powering on so I decided to try another power cable and it turned on and was running fine and even started hashing. Suddenly I heard the fans going nuts... And when I went into the room a chemical smell was in the air and smoke was billowing out of my psu.

And just so that you guys don't say I am bad mouthing Bitmain here is a video I took right after I turned everything off. The cable is a proven cable and there are no signs of melting on it.

Please kindly let me know what compensation Bitmain can offer. They have not responded to my emails on the psu replacement.

See https://bitcointalksearch.org/topic/m.9207574

Yes have replied to that email when they sent it out but haven't heard back from them. Sad

and the psu failed completely after I replied to them....

As long as the PSU fits inside the unit like the S2 and S4 I'm fine with that. You have to remember that a lot of us, myself included need a rack mount solution. Now for the bad news, due to the rate of increase on difficulty and the amount of chips required in these units, Bitmain is going to be pressed to keep future home miners in these small cases like the S1, and S3. There will be a day where you will need 2 THs as an entry level, that day is coming. Bitmain from what I can tell is TRYING to keep the home miners in the game but more people need to support the form factor of the S2 and S4, That WILL be the future … As I stated months ago, Bitmain needed to STRONGLY focus their R&D on the form factor of the S2… The S4 fit that bill, and I believe that they will resolve the issues… going forward, I suspect they MAY have to look into another controller, or look into a split brain setup of some type… I hope that this water cool unit is a novelty, I don't see it being a long term solution .
