Since I've added '/etc/init.d cgminer restart' to my crontab I've seen my 24-hour hashrate increase from 410 to 480 on my GOOD units. From 398-420 on my "Bad" units.

Some people are more code-friendly than others. chrontab is a bit too much for me right now.
what would be the string of code to put in after sshing to miner and in what directory?
If you don't mind, show us all commands, please.

One blade runs at 37 degrees while the other runs at 41 degrees all on stock 418.75mhz.

Any ideas what's going on before I take it offline to open it up, and lose some of the 440GH/s is generating?

It will be a crapshoot, the front-side heatsinks are not engineered very flat on their contact-side. I think someone said it best when they suggested tightening down the HS like changing a wheel. Alternate the screws between innter and outer.

After some fiddling I was able to get all of my temp sensors reading within 1C of each other and get stable hashrates with a restart routine and heatsink reapplication.

Hi!

Im a new miner from Spain, Barcelona. Best regards for all!

I have two questions. I hope you can help me because i dont have any idea to find the solution of my problems.

I have one Antminer S3 B3 and one is working with 2 PCI Connectors @250Mhz and hashs at 500gh/s but in one hour and a half the hash decreases to 360-380 gh/s. How is it possible? The status of miner appears to be OK, without any "X" or "-"... Somebody knows whats happening? Sad

if i reboot the S3 the hashing push up to 500GH/s but in one hour and half decrease too... Sad

In the status no HW errors and nothing strange. Only i can saw is a Little decrease of temperature... 47-44 grades @500GH/s VS 46-40 @365-380 GH/s.

I observed that my miner works more stable with 2 PCIEX connectors tan 4. How is it posible??

And the second question is for the second S3 B3.

I tested 250Mhz, 237Mhz, 225 and default 218.75 but always i get a lot of HW errors. How can fix the HW errors?? The only speed that no cause HW errors is 212Mhz.
I think the temperature is not the problema because its working at 43-43 grades.

Two S3 antiminers are working with the last available firmware of Bitmaintech and are new. Arrived this week.

Can you help me? Sad

PD:I hope you can excuse my English

Anybody?

The reason no one has responded is because your issues have been covered multiple times in this very thread. Your symptoms are exactly the same to what many of us here are experiencing.

At this time the only things that have a CHANCE of helping are re-pasting the heatsinks and setting up a restart routine.

just an fyi ELIGIUS has been very lucky 13 blocks solved in the last 24 hours.

Ghash has been INSANELY lucky over the past 48 hours. I'm up over 100% in the past 24.

Hey Bitmain, any info on B5 shipping yet, one post of yours said you were shipping a week early instead of the 7th.

did you check your e-mail or order? my b5 got shipped last night.

One simple idea would be to check the heating up board by opening up the miner and seeing if springs got caught up in a burr, therefore preventing tight contact between front heating sink and hashing chips. If they are, maybe tighten them up just a little bit and then check to see what happens. I would not recommend applying new paste because it did not do anything for me at all. Top line of "oooo" correspond to the left board if you look at it from the direction of the ethernet port.

Thanks, that is helpful. I do have some new paste on the way, just in case I decide to go that far with any of them. I'll poke around with a screwdriver and temp probe and see what I find. I'm gong surfing first though, I need a little R&R.

SO has their been any news from Bitmain regarding the s1 upgrades yet or this still a no go. As I see can only order from them for them in pairs of 2s and wanted to maybe buy 3 units and also buy upgrade modules for old s1s that are now beginning to collect dust.

My S1 is still profitable at stock speeds, but you might want to try under-clocking and under-volting, via a pencil mod, as I will be doing in a month or so. This will improve the efficiency of the S1.

What exactly is a "pencil mod"?

you have to read underclockers thread ^^^^^^, but basically you strike small R3 resistors once or twice with BB pencil, the result (once done on 4 sites on both board) is 140GH at 180W. You'll need a multimeter for this and possibly a magnifying lense.

Your are MUCH better offer selling your S1s and buying S3s than waiting for these "upgrades" that may or may not actually happen. I know these DIY projects appeal to us all but financially a miner that is just sitting around is losing money.

Edit: I don't see an upgrade to the S1 coming out anytime soon, if at all.

Don't put too much weight in the accuracy of the temp sensors. Is there an actual performance difference? Till it is obvious that the unit is not working properly I would leave it alone, get another temp reading device like a laser temp or even a simple stick probe and manually check the temps.

It will do 440GH/s at 218.75 but my other machine is doing 500GH/s at 250. The blade temps are the only thing that's different at the GUI, so I'm just wondering if this is an issue I can fix.

I think I have a thermo-coupler to go with my multi-meter. I'll have to break it out when I go to open it up.

I did see that some people had mentioned that, some of the heatsinks where not properly tightened down, so I'll be looking at those too, but I don't think that would cause my temp drop. I'm leaning toward an under performing component or components, or maybe to much paste causing capacitive issues.

Also, the primary reason why some machines work better than others, seems to be as stated by Bitmain, the DC/DC components not being quite being robust enough. There was talk that sometimes manufactures will sometimes push chip tolerances, which appears to be the case with the S3.

Bitmain did offer a rebate on the first 3 batches, then corrected the specs and lowered the price on future batches.

Keep in mind that this is brand new, barely tested technology. If your machines average 440GH/s +/-5% you should be happy.

yeah large variances abound form b1 to b4.

my b4's are stable at 478+478 = 956 freq 237 power 700 watts .732 watts a gh

my b1's are stable at 428+428 = 856 freq 212 power 656 watts .766 watts a gh

I am lucky that the b'1s are in a spot that running at lower freq was in my plan as sound and power use was limited. (a friends office with power at an 84% discount)

For some this big difference would be very annoying.

I believe I will order 2 more on weds or thur coming up. I think I will sell two on ebay along with an evga 1300 watt psu.

do you feel obligated when posting on ebay to disclose 428 gh speed vs 441gh?
