BITMAIN Antminer S1 support and OverClocking thread

[jusu_plus]

Hi everybody (my 1st post)

I have an Antminer S1 and I tried to find the right frequency settings for over 400MHz clocking. I have a seriously modded Antminer pushing at ~205GH/s with an HW error rate of 0.025%.

I know the 400 setting is

option 'freq_value'   '4f81'        #400M
option 'chip_freq'     '400'
option 'timeout'       '35'

but I am looking to overclock to eg. 410MHz --> 425MHz --> 450MHz

Could someone tell what the freq_values for these settings would be.

Much appriciated

Thanks, I tried to push the miner to 425MHz but 2 chips failed immidiately, or reported that they do not work. So I setteled with your settings 406MHz and so far it seems stable with temps @ 24C and 25C, ambient 17C / hw= 0.22% ...

Would really like to know what is 410Mhz and 415Mhz...

Update 20.9

Seems that 412.50 MHz is too much, 2 chips went offline and 406.25 MHz seems stable... All the hassle for just ~3GH/s... well you win some you lose some...

e: HW error rate seems to be around 0.25% ... Not bad at all...

What kind of power usage are you seeing at 406.25MHz? That's amazing how your miner is stable there - none of mine seem to be stable even at 375MHz.

I've got one that can run at 406 but the power draw is around 420w. I run it at 400 and another at 393 and together they use just over 750w.

That's not actually too bad, I thought power usage would be higher. Considering my S1's do 180GH/s @ 385W, 420W is very reasonable.

I was wondering if someone can tell me how to look at the 'real time load' graph.
I mean, what are those numbers telling me; what is the unit for those numbers ?

thanks in advance,
TurboDuck

those are the router stats. the S1 uses a tplink router module and openwrt software, similar to Linux. the load values you see are the system load values from the Linux kernel.

Hi sorry for the delay in my answer.

I have a power meter before my psu, and the power draw seems to be 450 ~ 457W. The powersupply is an Fractal Tesla 80+ 650W and it seems to work fine with the miner, with all the added cooling fans, and with added cooling heatsinks over the chips, condensators, and voltage regulators.

I used the following picture to analyze where to add extra cooling

http://cryptomining-blog.com/wp-content/uploads/2014/01/antminer-s1-btc-asic-miner-thermal-1.jpg


Also I rotated the setup of the miner so that the aluminium standard cooling sinks are on the outside with fans blowing into them at full speed (yes the noise is terrible)...

Hi all!

Can a single blade be powered at the same time, from ''power supply socket'' and 6pin vga connector, same psu?

thx

I think my 6pin cables are a bit to small in diameter, they are a bit warm at touch...

I have powered it with 1pcs of 6pin and then I have a molex -> pci 6pin adapter with 2 molex inputs. The cables get a bit warm but it works fine... But I would really recommend that you power the unit from 2 different cable sets, like I have.

1 - 6 pin pci adapter
2 molex --> 6 pin pci adapter and both are from their "own" wiresets.

[mavericklm]

I have 1psu/blade...

Got a 650watt psu with 1 6pin connector + splitter(sold with the psu) to 2 6pin connectors. Did work fine this way on both blades, but the main cable was getting hot.
Added a second ''700watt'' psu to the secondary blade and let the 650watt power only the main blade. And overclock it!

The ''700watt'' i believe has lower diameter wires because they are warm when touched...

Looking at the error percentage 0,05% i think i can give it a little push to 406.25 but already has weird behaviour like x on asic status, hash rate down to ~150, restarts.

Sorry if this was already asked, I just couldn't find it anywhere.  But here's my question:  Are you able to clock the Antminer S1 at a frequency that isn't something like  350, 375, 400, etc.  Something in-between those numbers.  I recently received an Antminer S1 and had it clocked to 375 because my PSU doesn't have enough watts on the 12 volt rail to go to 400.  I want to get the most out of my miner before it becomes non-profitable though, so can I clock it to something like 380 or 390?  I think I remember someone doing 389.9 because it ran better than 400, not too sure.  Thanks and sorry if this is a stupid question, I'm new to Antminers a bit.

Here you go:

Code:

        option 'freq_value'    '5f05'  #393.75M
        option 'chip_freq'     '393.75'
        option 'timeout'       '36'

        #option 'freq_value'    '5e85'  #387.5M
        #option 'chip_freq'     '387.5'
        #option 'timeout'       '37'

I have a question regarding the  '5f05'  What is this value used for as mine is set at 4f81 and clock #400M time out 35 and chip freq 400

I have a question regarding the  '5f05'  What is this value used for as mine is set at 4f81 and clock #400M time out 35 and chip freq 400

The 5f05 is 393MHz chip frequency and somebody calculated that in a normal setting it is the most efficent frequency as HW errors are under 0.1% ... but it all depends on your ambient and how well you have ventilated the device...

I'm trying to make some small adjustments to balance out the HW error rate on some of my undervolted S1. I'm shooting for a frequency of 265.00 . I've searched and it isn't in the frequency table:

I went through the thread and found I needed to check the antminer U1 user manual that has the formula for calculating frequencies. It is also in this post: https://bitcointalk.org/index.php?topic=348327.msg4549088#msg4549088 I understand how the numbers work once you have a hex value, but that is the issue. When I input the hex value of 265 into multiple calculators online I get a hex value of 0109 and a binary of 000000010000101. Those values worked out do not follow the Fout rule and I wind up with a frequency of 12.5. If someone could point me in the right direction of figuring out a frequency value for 265 it would be greatly appreciated.

Im having a issue here now to overclocking my s1. When I open PUTTY and type in vim asic-config I never get to see actual stats in here. Its just a black screen that says
"asic config 1/1 100%" that's all. Why can't I log in through PUTTY like I see everyone else? Am I missing a step?

The commands are:

cd /etc/config
vi asic-freq

You don't need the m in vim, just vi asic-freq .

PS: Someone post the info for frequency 265.

[Convicted2008]

This does not work. I get the same message that I stated earlier. I do not get the info that everyone else does. Its just a black screen with asic-freq 1/1 100% at the bottom of the putty screen.

cd /etc/config
ls

Post the output of that here.
