It wont fall further, there are very large buy walls already in place. Someone is clearly trying to dump the price, but that just means loads of cheap hyper, and im buying all day long!!

The key is temps. They must be held to a minimum at all times. Also dont EVER run them over 300mhz. They will run at 325mhz for months, but then fail. Havent had a failure yet at 300mhz.

I didnt think twice when the weak hands were dumping. I didnt buy enough when it was 50k about a year ago, so when it dumped to 70k and 80k, I quickly scooped up a few thousand. We will see 180k again, easily.

the chips were getting so hot that it discolored the machined edge on the copper pipes used to make contact with the chips Ya, many of the failures are from the wafers getting so hot, the solders balls scorch and lose contact with the pcb. I may have to look into a reball machine. Problem is there is no stencil made to my knowledge for this chip. Vegas |

Ive supported this coin from the beginning. Glad I did. Coin just needs more time, more people to find out about it. There are very few honest devs left, and Dev Jay is one of them!!

Just got a pm saying that another round of DPOS will start today. They said its DPOS V3.0. Ive never heard of DPOS V3. Not sure what the difference is.

AWESOME!!!! As always Grampa keeps his promises!!! Ill post on my site and get the word out!! AWESOME!!!
Ill be buying loads coins first through.. LOL

You can order a precompiled firmware with no donations. Look in my signature for the order page. Thanks for testing the security system  Vegas |

Guys this is his first coin and he is a respected member, so cut him some slack. He wont be pumping out a shitcoin quickly like newb devs. This will be quality and well worth waiting for. Patience plz.

Hey vegas are one of these on the hashing board? tps65217
I would think thats for the FPGA but double check.

If you remove the LCD screen, thats a 6th port to add a 6th cube.

As im finishing testing everything, youll see how serious I am, as I am going to amass large amounts of Ros on a daily basis to get ready for the swap. This proves how serious I am. I have no other reason to buy Ros than to have the largest possible % in holdings. There is no inside information or tricks. Im accumulating massive amounts of the ROS , so I can have a larger percent of FLY. Its fair game.

HAHA! Figures, well it must have a remote temp sensor somewhere. Would have to trace the traces... which being a multilayer is impossible.
I bet the sensor is somewhere or in the actual ASIC package.
It would be super retarded if KNC just put that there and the sensor was close but all it did was measure ambient, lol Id wanna burn their farm down then, oh wait I already want to...
A schematic might help.  |

ok location of LM75:  close up of LM75 (you can hardly read it, I had to use a magnifying glass) :  |

agreed, and I think you might be right. I found this. Its old but might have some helpful information. https://bitcointalk.org/index.php?topic=307055.0. So are you saying in the advanced page , the temps to the far right are the vrm temps? If thats true, and I think it might be, where are the temps of the 4 cores found, or do they average it on the status page? I think the next update might need clear labels on these numbers , as KNCminer gave us temps, but for what!!? Everything is not labeled in the miner, and its needs to be to clear up all of this confusion. Vegas The pages are already correctly labeled LOL! DCDC = VRM's ... loosely interchanged to refer to the same thing. The temperature column on the status page grabs those temps directly from a LM75 sensor... I dont know where this sensor is on the board, could u inspect the underside of the board perhaps? maybe there is 1 LM75 sensor mounted beneath the ASIC package. Its reading temps through the board, or maybe somehow the LM75 is integrated within the ASIC package. But there has to be one LM75 sensor somewhere on these damn boards. Either way, I suspect its an external sensor for the ASIC package. It functions to readout external package temps which are usually a good 10-30C less than actual die temps. Out of curiousity how much did your temps change by when u slid the HSF around? I have 2 theories, 1. when sliding HSF around this could potentially change airflow caused by your hand etc... and therefore the DCDC's were being cooled more or not depending on that airflow aversion. 2. If slid the HSF caused temperatures to skyrocket for a short period the dies may have went into a limp mode to avoid being blown up. I suspect there is no on die temp sensor, otherwise we would see it being used. We arent. Hey vegas, w/ ur thermal sensor thing, can you read temps from atop the base of the HSF while its hashing? Actually, if u could aim the laser at the package underneath the heatsink as its hashing, that would be really telling. If its close to the readout of TEMPERATURE on status page then the ASIC is using a single external package temp monitor. (thats already my suspicioun anyways, but it would prove the theory) What I wish we knew was the TDELTA between the dies & the package temp sensor. If I knew what that DELTA was on average, I could code it into the firmware to reflect the correct average temp of the dies. Ok I can run it with plate only and give a readout of what my temp gun says and what "temp" says on status screen. Ill let you know. If these are within 1C +/- I would like to see it reworded "average die temps" on status screen. There is no chips mounted under the pcb, Ill check the layout of the board, and post a screen shot too and see if we can locate it. Vegas |

GenTarkin that's how I think about it too, HOWEVER I have seen when the thermal paste is applied incorrectly then gets a bad temp reading and when fixed it improves the reading on vrms?? why I don't know, since they are physically separate
maybe the temp reported in dc/dc is an avg of 2 temp sensors, 1 on the chip the other on vrm?? so replacing thermal paste and applying heatsinks to vrm will both improve the temp readings??
Well thats odd. Either way, in the source code, the 2 temp fields are derived from reading the DCDC's internal temperature register. The temperature shown in status page under "Temperature" column is derived from LM75's temperature register. Is LM75 the FPGA?... Im not sure but after seeing this: http://datasheets.maximintegrated.com/en/ds/LM75.pdfIf that is identical to what our LM75 is ... then Im inclined to think the LM75 is some sort of external temp sensor that maybe sits as close as they can to their respective places around the dies? I dont see anything labeled LM75 on the picture u showed, are there any surface mount pieces on the bottom side of the PCB? Maybe LM75 is integrated into the package somehow, doubt it tho. Im just guessing tho =) I am not sure, everything is running fine at 325 MHz, so I don't want to think about it too much lest they get mad ... Just dont make eye contact  Vegas |

Ok found this and Tarkin looks like you are correct the 8 temps in advanced page are temps for VRMS. https://bitcointa.lk/threads/swedish-asic-miner-company-kncminer-com.100083/page-1804So It would be nice to label that properly as VRM Tempretures. I also agree 2 vrms per 1 die. But if its possible I would like to see the temps of the 4 dies displayed indvidually if possible on next release as seen on earlier link. Its probably from a jupier or neptune, so I hope we can do it on the titans. Vegas |
