I am currently running stable for the last two days at roughly 455GH/s at frequency 225. From frequency 218.75 (The stock my unit shipped with)
Temperature up by only a couple of degrees.
37 --> 39
38 --> 39
Fan RPM up by about 600
1260 --> 1800
1020 --> 1620

Do you need to connect the other 2 power connectors to OC?

Well good news for you, i got one unit that do not handle any OC and the other one perfectly. (OC to 250 mhz at 503 GH/s) |

And is this secure?? I mean... there´s no risk S3 explodes or something? xD
This has me curious as well. I never did overclock the S1's I had, but I'm thinking of overclocking these dudes. I'm really hesitant, though, on the count of them already needing to clock them to 218.75 stock :| Was thinking of nudging one up to 225, but don't want to risk burning my house down. A few kilowatts really throws the heat in mid summer. Almost wish this was January. I'm terrified to leave the house in case a cable melts and 'POOF!', FD calling me to tell me that I screwed up. My 16gauge cable melted or something random I overlooked while frantically getting them online and neglected the cooling. Soooo hot.. |

I have 2 ant's. Will post more after further testing. One OC's very nice the other default clock speed seems to work best. Both batch one. It seems hit/miss but know it will be better on batches to come since they know the cause of slowdown in the batches they are offering compensation for (coupons/partial refund in account).

Anybody could post high quality pics of the back side of the PCB under the 53355 chips?
I can't read the values on the high res pics from Dogie guide, and it seems it's the place they have put the divider resistors that we'll need for overvolting. I believe I already identified the resistors, but I'll need the value to start the work while waiting for my S3 to arrive..

Found out why one of my units was not hashing and having X's on the chips. Paste was everywhere on the inside. Even the screws holding the heat sink on had thermal paste on them. If you have a unit that is not hashing correctly, I suggest taking it apart and cleaning them.   |

Your image alerts everyone to unscrew the heat sink, clean and put some thermal paste again properly. In your image the paste is not properly placed to exchange heat from ASICs. Do it even if its hashing well if it should be cared more. Else, do it if, the temperature is abnormal or hashrate is lower. |

Isopropyl alcohol works the best, usually for thermal paste. |

Remember to apply a good thermal paste after you've cleaned the original one  The 4x cabling: seeing the paths on the board it look like both inputs are powering up exactly the same (i.e. this is not an additional board/unit, just a duplicate input) so I guess the "use 2 cables per hashing board" requirement is mostly due to possible cable/solder overheating due to high amperage. Has anyone already tried sticking radiators to the R47 elements? does this do the same magic as it did in the S1's? (lower HW which seems to be the issue here) |

Is there a go-to power supply any of you have been going to power 2-4 of these units?
Most seem limited on PCI-e cables, I would love to know.

Strangely on both of mine. their conf is
option 'freq_value' '0982' #225M in comment instead of #250
option 'chip_freq' '250'
option 'timeout' '16'
The 225 settings are (currently using this setting @ 453 gh/s avg from 440gh/s at #218.75M)
option 'freq_value' '0882' #225M
option 'chip_freq' '225'
option 'timeout' '16'
I was looking for the #250 option which wasnt there and then i spotted the chip freq value of 250 in the #225 settings
