ANTMINER S3+ Discussion and Support Thread

[Biodom]

Hey just a quick one - I feel I am missing something here. Maybe someone can enlighten me.

I have an S3 B1, running the following...
antMiner_S320140826.bin
cgminer 4.6

Load is nice and low - but the hash rate seemed to be below what I am seeing on other S3's  - so I was trying to push it a bit beyond to see if I could 'encourage' a few extra GH/s from it.

So SSH'd in and added the following -

option  'freq_value'    '1406'     #256.25M
option  'chip_freq'     '256.25'
option  'timeout'       '15

:wq -> reboot - but it is still showing as 250 in the gui - can anyone confirm if the new 'Advanced Settings' tab under 'Miner configuration' will over ride the manual entries I made in the asic-freq file?

Also - while I am at it...

I have such wide variance in the hashrate of the S3's anyone any suggestions on coaxing the slower ones towards 500. 2 of them are consistently at 505+ but some just seem determined to go slower - like sub 440 and even down as far as 400. Have tried playing around with freq's and FW and different PSU's etc. Has anybody had any solid results with checking/re-applying the thermal paste or even just re-seating the heat sinks, as I have not gone down this road yet?
Thanks

I don't think that after August updates you can change speed by ssh. It seems that advanced config, indeed, overrides ssh values.

Do you know is it possible to add the higher settings to the drop down?

testing cgminer 4.6 again on a single miner now that the DDOS has let up...

It is sitting at 500+ now. I suppose that DDOS that was going on effected my speeds yesterday and or one of those odd blocks that 'seems' harder to work on...

Got 1 of my 2 S3 Batch 8s today hooked up and running. Seems the other one is still out for delivery.

So what freq and hash rates are you seeing?

at stock 225 freq about 457 avg for the last hour. look here for its stats https://www.miningrigrentals.com/rigs/8216. the other one is lost in package delivery land lol.

My 2 b8's came in today. After 10mins stock, I noticed hashrate near 453gh as advertised. Just oc'd both of them, but way too early to tell. I will let them run the rest of day and post back if they are stable. I assume they will run ~500gh, my 2 b6's run stable at 504gh. I may have to move them around and that will require restarting them, so I may not know if they run stable OC until tomorrow.

Finally got the newest cgminer install on both my miners. Thank you twib2 and everyone for their help. ANd thanks to Kolivas for the fantastic job

The problem S3 which I changed out the thermal paste was down about 430 this morning.  I had moved both into the back room last night as after a warm day it got uncomfortable in my living room.  So, I restarted the problem S3 this morning and it has been getting warm in there, 91° 31%rh.  It has been running well since rebooting, the warmer room and low humidity.  6hr50min 440.91GH/s, 0 HW, but utility is 15, fewer shares tho the score seem equal to the other.  It's temps read 47 & 46 while the #1 unit is reading 44 & 42, running at 441.60 HW 160 in 15 hours but its utility is 16.

Having learned the art of building heatsinks for high voltage FETS in the late 1970's, what you want for perfection is two perfect surfaces in contact but since perfection isn't possible you want as little thermal paste as possible filling any air gaps between the surfaces.

When I took the inner heatsink off a hashing board, a good board by the way, the thermal paste seemed applied by machine in 4 rows along the top ASICs and 4 more rows along the bottom ASICs.  It was not well spread, just flattened.  There were air gaps between the rows.  Thermal paste conducts heat less well than the copper on the board or the aluminum.  So, essentially the heat went from the copper plane to the rows of thermal paste to the aluminum on the other side of the thermal paste.  I removed it all and applied an even thin layer of thermal paste to the surface and tightened from the center out.  When doing the outer heatsink I suggest you carefully remove it after removing the 4 spring'd screws but not to slide the heatsink while removing.  If you lift it up and off you won't build up thermal compound on the very fine ASIC pins as might happen if you slide the heatsink to the side.  I'm sure the stuff doesn't conduct but dust might adhere to it at the pins over time.  Big mistake is thinking more paste more conduction.

Also, as you remove the silver thermal paste from the inner heatsink, you may notice a couple or more small lumps of solid thermal compound stuck to the heatsink.  At least that was the case of the bad hashing board that had new paste applied in addition to the original.  No way that heatsink could have been flush, it stood away from the copper plane at least the depth of the hard lumps.

Where are we at with order deliveries guys? Anyone shipped who ordered at end of August?

Also, I haven't noticed any posts from people about the upgrade kits so assuming these are being posted last

My upgrade kit order (48 kits) is "in shipping status" as of late last night (Eastern US timezone for me), waiting for the tracking number.  I expect them to arrive by early next week if they follow the same timing as my B5's.

Edit: for reference, my order was placed 8/14.
Edit 2: also for reference, we went through 112bit.com, not through bitmaintech directly, but I don't think that's really much of a difference.

5 hours in... hashing is slowly dropping. at 491gh/s now. 495 is the the set average for old cgminer.
yall sure I dont need to install the newest firmware?

Discards do not matter. CK said they mean nothing and should never have been reported and tracked in the first place. The "-" you see is a malfunctioning ASIC. It should still be under warranty and BitMain can help you fix it if the chips is bad. I got someone good when I had a under performing board and they replaced it.

Before you do all that "-" is not a dead a ASIC "x" is and even those can come back (I've seen it) power off the supply try moving your PCIE cables around. I assume your only using 2 one on each board, if your using 4 unplug 2 (if no plans to OC) and then power the supply back on. Reboots alone don't always fix S3's. I agree discards don't matter.

im getting a lot of discarded shares with my new s3s as well. people say they don't matter, but it seems to make a difference...

the s1 seem way more consistent.

one of my s3 bounces around 460hg to 400gh with lots of discarded... 2x more discarded than accepted...

other one stays steady at 450-460gh but with 2x more discarded than accepted shares...

Discarded shares don't mean anything on the S3. Ckolivas has confirmed this himself.

[navigator]

So, oc'd 2 b8's for 5hrs and 1 is running pretty stable at 503gh, the other keeps falling to around 480-490 and showing 1 x. It goes away after restarting, but comes back after a few hours. Might try lowering it's clock a lil to see how it runs. Bought to upgrade cgminer on both.

[xstr8guy]

This constant angst over a few GHs is so pointless. Just let these things run and quit wasting your time and energy trying to squeeze out (literally) a couple of extra pennies. Downtime from messing with settings and firmware and reapplying thermal paste is doing more harm than good to your earnings.
