Any specific Modell or random one?
Whatever is cheapest. Do you currently have one though? Because it appears based on your initial question you don't.

My S3 isnt connecting with the pc , firewall is down the System is Win xp i ve a crossovercabel and the Miner is working

Excuse for my newbie question but i dont know how to Start my S3 !.? I ve also a netadapter 650 Watt Gold 80+ and a crossover cabel and a Laptop WITH Win xP
Do you have a router?  I would invest in a router if you don't already have one.

You're going to need to get onto the S3's dashboard and configure your set-up.  I would invest in a router if you don't already have one.

Then follow the S3 guide here.
Post was answered last page. We need more information to help you. Try the guide and if you still have problems come back with those. If you don't have a router, I strongly recommend one.

anyone familiar with openwrt's implementation of opkg? apparently on the S3's "OPKG Update" isn't working.

When I run it i get the following:
Code:
root@LabS31:/# opkg update
Downloading http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/Packages.gz.
wget: server returned error: HTTP/1.1 404 Not Found
Collected errors:
 * opkg_download: Failed to download http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/Packages.gz, wget returned 1.

I checked the path at http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/ and Packages.gz does not exist.

Anyone have a clue how to resolve this?

LOL i don't look at HW errors. The PSU is Cooler Master V850 80+ Gold and i connect all 4 PCI-E.
I read your result and now i try to hardcopy the page of Antminer and post results.
Thanks.

I thought that you may be under-powering your S3 and suspected your lack of increased hash-rate was masked in the HW errors (as opposed to X on the chips). however, 850 watts is more than adequate to overclock an S3, and as you can see from my results, I only used a 550 watt PSU with just 2 PCIe connections!
Well well, looks like you drew the short straw with your unit, but at least you got the voucher to sweeten that!

My Antminer is Crazy???
I have tested frequecies and my antminer don't overclock:
Antminer S3 Batch 1, time of test 24h each frequencies, same pool, same user:
206,25Mhz - 414,73 GH/s - 1980/1740 rpm - 41/40 C°
212,5 Mhz - 428,08 GH/s - 2160/1920 rpm - 41/40 C°
218,75Mhz - 410,01 GH/s - 1980/1800 rpm - 41/40 C°
225    Mhz - 406,56 GH/s - 1800/1670 rpm - 41/40 C°
231,25Mhz - 393,64 GH/s - 1980/1800 rpm - 41/39

No X on chip.
Is impossible for my antminer run overclocked?
Can help me?
Thanks

I believe the earlier S3's do not overclock as easily as the later batches (and thats why the first batch received discount vouchers I believe).
Aside from that, you mention you are not getting any chips marked with X but you have not mentioned whether your hardware errors. Are you sure you are powering the S3 adequately and what are the hardware errors?

I did a similar test, but on a batch 6 S3 and posted the results here: https://bitcointalksearch.org/topic/antminer-s3-batch-6-overclocking-750220

Bit layout for the freq_value is as follow:

http://s24.postimg.org/ftzr6e7w5/freq_value.jpg

OD can have values between 0 and 3
R can have values between 0 and 31
F can have values between 0 and 127
BS can have only 0 or 1

From page 6 of BM1382 spec (https://www.bitmaintech.com/files/download/BM1382_Datasheet_v3.0.pdf) you get:

NR = R + 1
NF = 2 * (F + 1)
NO value from OD value (see Table 4 from same spec page)

Fref = Fin / NR
Fvco = Fout * NO
Fout = Fin * NF / (NR*NO)

So Fout is "chip_freq" and can be calculated based on valued from above ("OD", "R" and "F"). BS select "high-band" or "low-band" (see page 7 from BM1382 spec for valid freq values for each band).

chip_freq = 50 * ( F + 1 ) / ( ( R + 1 ) * POWER( 2 , OD ) )

For timeout I used following formula:
timeout = 4000 / chip_freq

I suggest to calculate all 3 Fref, Fvco and Fout and make sure all 3 value are in range described on page 7 for the band specified by "BS" value.

Hi folks, given the above, I have thus calculated EVERY POSSIBLE valid frequency and register value. I don't know about the time out, so for that I just used JakeTri's timeout formula to get the time out and then took the integer value:

Assuming:                                 
Fin =   25                              
                                 
Fref   Fvco      Chip Speed      Register Value            TimeOut

25.0   1600      400.0000      0x   0   F   8   2      10

For the above paste, in the interest of space I only presented speeds up to 400.

Note that if the frequency does not show on this list, it does NOT exist, (except for ones above 400mhz) as these values were calculated from EVERY possible binary value of the register, then filtered for valid values based on the criteria in the datasheet.

I do not know the implications of the Fref and Fvco values, so I sorted everything from lowest to highest. For a clock speed of 200mhz is it best to use a Fvco of 800 or 1600? furthermore, within those results, is it best for Fref to be 12.5 or 25? Given BitMain's example in the datasheet, evidence would suggest they want us sticking in the low range bank, with Fref=25. If there's any good reason for that then that reduces the possibilities to:

Fvco   Chip Speed      Register Value            TimeOut

1600   400.0000      0x   0   F   8   2      10

But i imagine people are willing to try other than just these values, since folks are asking for speeds between 237.5 and 250 (the only one is 243.75 but with two options) and i assume 243.75 has been tried/tested by now?

I can post my excel file so people can check my work, and/or if people want to see valid chip speeds up to 3000mhz (i'm pretty sure you will NOT be able to run at 3000mhz! so don't get any bright ideas) Smiley

Qty. 2 - S3+s

As a home miner, I'm wondering if I should set the IP Address to DHCP

or set the IP addresses manually inside the range of my router (or outside the range

of the router).

I know they come 192.168.1.99. So, I will have to assign a different IP to one of them..

My home network range is 192.168.0.1  -  192.168.0.255

Any recommendations on this?

I recently ordered a pair of AntMiner S3+ and looking forward to receiving them in September.  I've come across a possible good deal on a power supply and wanted to share it.  If you're looking for a higher quality power supply Platinum rated, and don't just want a low quality simple one or a used one, check out the Rosewill Tachyon 650w at newegg.com.  They currently have it at $140, but there is a 20% off code available (-$28.00, ends 08/27) on their website AND a $30 Mail-In-Rebate.  This seems like a good power supply for a single S3 (overclocked or not), and it's partial modular also with 4 PCI-e connectors.  I'm currently looking at a computer case that can house the AntMiner pair at my office without it being messed with, anyone do that?  Any suggestions as to a case to house multiple S3's, I think I've found one that can hold 3 or even 4 of them and the power supply(s).



    82 dollars for one unit .  

a lot depends on how many s-3s you use.  if you have 3 s-3's   or 6 s-3's   the evga 1300 watter is  a  very good price point

190  at amazon

drops you down to 175 for 3 s-3's  only 1 power plug needed.    under 60 an s-3


I have this and run 3 s-3's pulling 1110 watts  set at 231.25 -- 231.25 --- 237.5

I am currently using 4 HP server power supplies, and I have 4 dell power supplies ordered.  All are 80+ rated.  I learned how to set the jumpers and solder binding posts from googling server power supplies and RC car stuff.  The new dell PS's are 220/v 1570w, 110v/ 1000w.  

I'm working on doing fan control with in the newest firmware revision.  I'm trying to set the --target and --overheat settings in the general settings tab.  So far I can rewrite the cgminer config file with the --target setting but it gets all garbled up.  The tab shows up and drop down list in the general settings though.  I don't think I'm using the correct syntax.  Is anyone else working on this?  Or have they tried?  If anyone is interested these are the changes I made:

pb = conf:taboption("default", ListValue, "bitmain_notempoverctrl", translate("Stop running when temperature is over 80 degrees centigrade(Default: true)"))
pb.default = "  "
pb:value("  ", translate("true"))
pb:value("--bitmain-notempoverctrl", translate("false"))

pb = conf:taboption("default", ListValue, "target", translate("Target Temperature(Default: 30)"))    
pb:value("--target '20'", translate("20"))
pb:value("--target '25'", translate("25"))                  

I made big changes so I could hear which miner fans were kicking up.

Free shipping too.  The 750w version (single +12v rail is rated at 62A = 744W) would probably be a better choice for a pair of S3's non-OCed, but that's out of stock.  They don't have a 850w version, but the 1000W version might be considered for OCing a pair of S3's because the single +12v rail is rated at 83A = 996W, but at $200 there are probably many other better choices, even Platinum rated power supplies.

I don't plan on overclocking.

I purchased Qty. 2 - Corsair HX650 PSUs for my Qty. 2 - S3s

The Corsair HX650 only has 2 PCI-e connectors

So, as long as I'm not overclocking the Corsairs should be fine, right?
You are fine even if you do overclock to 250Mhz.

Excuse for my newbie question but i dont know how to Start my S3 !.? I ve also a netadapter 650 Watt Gold 80+ and a crossover cabel and a Laptop WITH Win xP
Do you have a router?  I would invest in a router if you don't already have one.

You're going to need to get onto the S3's dashboard and configure your set-up.  I would invest in a router if you don't already have one.

Then follow the S3 guide here.
