Hi guys i have 2 antminer s1 with 2 500 watt psu but tehy makes me xxxxoxxxoxx i know this psus is too low and cheap for OC . I have in my PC CORSAIR TX 950 watt . What do you think , can one tx950 jandle 2 antminer oc to 200gh/s each ?
Till now i use 500 watt chap psu each for oboth unit.
please answer if better to buy two new stonger psu or just change and connect 2 miners to corsair tx 950 watt

HI
 I run 7 S1. - OC to 200.
  Each on different PSU. I had the same Issue with "xxxx" marks. Biggest help was to flash firmware to new and better cooling (mounted secons fan to the front side of S1 - pulling air out of S1). Now they are without XXXXX.
 But xxxx doesnt mean they are not working. My S1s were marked as xxxx and still hashing well. But it looks bad Smiley
 So now they run about 41-43 celsius and working well.


What psu do you have ? Xxx showing to me after 25 hours, i just restart and again runs well just everiday i has to restart.. when i cout HW errors is really small 0,7 % soo just this restarts every day. I am thinking to buy to psu 750 watt

I use 750's and after 2 days I start seeing X's refresh a few times and they go away.
.7% Hardware errors is extremely harsh, I had one doing .05% errors and it is being replaced as a faulty unit as all my others are .0003% over clocked
~1% is pretty normal for mine at 400MHz. Even the ones kept reasonably cool (20-25C on the temp sensor) still get 0.1%-0.3% errors. 0.05% is hardly faulty. Are you sure you're doing the math right?

I may be grabbing the wrong number I am doing HW/localwork
The machine I declared faulty has 1+ million hardware errors over 4 days where the other 3 have 80,000ish.
the faulty one mines at 190 gh/s where the others sit around 204 gh/s

Generally it's HW/(DiffA+DiffR+DiffS+HW)
Even then, I'd guess at ~200GH/s your number of shares over 4 days is around 16M or so. 80,000/16M is still 0.5% HW errors.

I know I can, but I am looking for lightweight solution I can code on my own, if it is possible... No need to use python + going one step back by using getwork if I can eventually code everything in C for super fast execution and when I will need to scale this to great sizes.
Check the -sp option for the proxy - it will let you accept stratum requests from the local miners not only getwork and for getwork the -nm option will reduce the load on the RPi a lot and you may skip the C midstate extension completely

The proxy will use single connection to the pool even if each miner uses it's own user/pass, but may also be configured to rewrite the credentials provided from the miners with a single one (-cu -cp options)

If you really want to get rid of python and write everything in C, you can closely follow the proxy code logic and just skip the getwork part

this is a fucking joke, and fucking funny shit with the LMGTFY link..  If it cant be explained then the one place I have trusted since i started mining almost 3 years ago has turned to a fucking joke.
It was explained several times and when you ask for an explanation
Someone please explain to me how this works?
It is as simple, as to google for it.

As others have pointed already, your shares for the 21728 round are missing ~20 min and because there is even bigger amount missing (~35min) for the next round it is clear that you had some connection issues for ~50min

Submitting a ticket for cases like this will not help, because it is not a pool problem and similar numbers will have a pool hopper who left the pool and is now cheating to get his lost reward.
I am not saying, that you are a pool hopper or trying to cheat, but there is no way to differentiate the two from the pool's perspective.

Last week in addition to the pool's bad luck i had (just) 5min connection drop, which resulted in 1/3 of the reward for an 11h block, very unpleasant, but not the pool's fault - you either accept, that because of the score system it is possible to have such cases or you choose another pool (especially if you often have connection issues).

I should add to this that despite what's been posted on here before, your expected value doesn't change with the way this pool is scored. It just raises the variability of it. We always tend to focus on the negative outcomes and so we all notice if we have a rig down for a half hour in a two hour block but get almost no reward. By the same token though, I've taken systems down for maintenance/changes and brought them up after a delay, and my reward for that block ended up being essential unchanged compared to if I'd mined constantly. Statistically it works out to the same in the end.

Did the same many times, people hate the maths and are rewarding 'Bragging rights' for a statistically 99% guaranteed prediction. There is still 1% chance the block is found during your maintenance, but if you do your homework you may choose the best time for the maintenance.
Yes, it is similar to pool hoping and instead of maintenance you can switch pools for a while, then come back and loose nothing.

Similar situation when bringing a new miner online.
The new unit was running for about 30 mins and scored about 90% of the value for the entire round compared to the existing miners.

30 mins and scored about 90%
Enough info to calculate the constant for the Slush score system actually Wink

BTW
80k/16m is .005% error
1m/16m is .0625% error

ok real numbers
122,059/(122,059+28,345,368+40,741+0)= 0.0042815448540923
66,338/(66,338+15,905,645+19048+0) = 0.0041484504657642
same with the other so my cranking ones doing 204gh/s are at .004% hardware errors where the one I got replaced was much worse I dont have its numbers anymore but over 8days it had like 2.2million hardware errors and mined at 190gh/s
the 3 cruising ones are 1/14 where the other was 12/13 with a fan that would not exceed 2000rpm so it ran like 4C hotter

BTW

1m/16m is .0625% error
% means 1/100, so you need to multiply those numbers by 100 = 0.5% and 6.25%

Is the captcha really necessary on mining.bitcoin.cz?  What is with this stupid trend to have captcha in every fucking corner of the internet?

Hardly anyone speaks English on this forum.

it stops your btc from being hacked easier...

however this captcha seems to fail 1 to 2 times when I enter it correctly

ok cool... I got rid of the 6% one. It made me edgy!
