Great thread!
I have 16 S1 boards in the UK if anyone is interested in buying them.
Topic: [DIY] - Reward $100 | Antminer S1/S3 Blade on Raspberry Pi - page 9. (Read 82134 times)
current info: running time - 15 minutes
GHS: 473.69
Watt: 469 at wall
when i start it up several of the blades produce a lot of errors, but it equals out over time...
i will post stats after 6 hours again
tried that => cgminer.exe --bmsc-options 115200:60 --bmsc-freq 0881
I see all the chips been set to the new freq then after that boom process crashes.
Initialization of the boards look all good.
Very strange.
EDIT: restarted using my old command line => cgminer.exe --bmsc-options 115200:55 BOOM they all run to 57 GH/s
EDIT2 : Switched for 60 ms. still around 56-57
that is strange...
do you have a linux box to test on?
I got my Raspberry Pi, but i still need to buy an usb hub.
mine sucks
EDIT: I also run the your compiled version for Windows
EDIT2: anyway, no big deal. i just have to set the freq to the boards, process crashes after the freq part. Restart it without the freq and i'm all good. I guess i have to do it for every power shutdown on the boards tho.
EDIT3: running for the last 9 hours or so
0: AMU 0 : | | 59.11G / 57.30Gh/s WU:800.5/m
1: AMU 1 : | | 57.67G / 57.08Gh/s WU:797.5/m

well, got my ant blades down below 1 W/GH
254 GHS vs 241 W :-D (5x ant s1 blades) = 0,949 W/GH
254 GHS vs 241 W :-D (5x ant s1 blades) = 0,949 W/GH
Cool !
What is the voltage and resistance ?
measured resistance is aprox 1.85k, voltage 0.75ish, but each bank has been finetuned for optimal performance, so they all vary, and they run at 200 MHz with timing 60
Mine are at around 2.75K / 0.84v doing 49.2 gh/s timing 55. I'm surprise you're doing better with less voltage.
what bmsc-freq are you using?
default, so 200
try these instead:
option 'freq_value' '0881'
option 'chip_freq' '225.00'
option 'timeout' '60'
option 'freq_value' '0981'
option 'chip_freq' '250.00'
option 'timeout' '55'

Use UTP solid wire to connect and make them as short as possible.
Its noise thats your enemy.
I dont quarante but should improve things

@ Sobe-It:
Grazie, mia S1 lavorare dal 32 Chips! (only if the -IT does not stand for Information Technologies ;-)
Thank you, i measured the 0.843V and did a link between the capacitor's on the positive
side, so there is no need to scratch the PWB. First i checked the volatge on the TI to not get in
conflict with a internal shortcut. What should i say, it works.
I also looked into the datasheet of the TI and in my case with the undervolt (Resistor add in through hole, not smt) the TI got reserve.I try to add some Pictures of it later that evening for making it easyer for all.
I also think about the value of chips and the chain, i can do both Linux & Electronics, so i keep you informed.
Edit: add Photo's
Repair of my S1
Undervolt mod with normal resistor
Measurement of current after the mod.

so i finally got around to soldering 2 boards into one. i took off the 1st and 31st chip. so in total there is 61 chips. when i go to set freq all chips seems to report back. it hashes 80ghs-90ghs for a little and then slowly drops, it shoots alot of hw errors. im thinking its a timing/clock issue.
You are the man!Yes you are right, it is a timing issue as the timings are for a chain of 32 chips. I'd hazard a guess that if you set it to a fraction of the timing you have for the frequency you are running at, then you'll have less HW errors and a hash-rate improvement.
Once again, YOU are the man and well done for taking one for the rest of us mere mortals!
EDIT: Any chance of photo's of the mod on both boards? That will be super.
Also, (and I am sure you can handle this), but if you want some input on the timings that you can try, could you advise what freq you are running the boards at?
my experience was that at lower voltage/frequencies, timing needs to be higher or yout et a lot of 'x' chips (seems to be the chips further down the chain in my experience). Of the 4x S1 units i have, if i set timeout to 70 or greater theres no hashing and the unit beeps. 55-65 timeout is most effective for undervolted gear

i would suggest to try at half the timing your using now, then work upward with a jump of 2
