If the gh-speed doesnt start initially from high value, then miner settles down to lower value. This is strange but perhaps there is some "initial modification" done on cgminer that sets the rate for rest of the session.
Sometimes i have to restart like 10 times to get this "high catch" effect. Its pain to wait in between, because without delay you just get fault 96/97 on vrms. Which means restarting the miner from the page (I dont like to switch off power but had to do that some times)I always wait like at least 45 seconds if vrms have been running for a while to let them cool down.
I've noticed that too, but my unit almost does it every time...if you mess with the spi freq. that can do it i think...cause i just increased mine and it didn't do it anymore...went back to stock and it did it again... well on 251 with oct. jup...thxs to the graph i was able to finally get the hw error down to .4% and 718-723gh/s on cgminer, bertmod says 700w same as 241, but that was before better cooling fans added...have one board at 240a :O hope it doesn't fry..and also 1 board at 200a but its at 42c  Hopefully pool will report higher hash now that i got the hw % down i'll know morrow morning ok 251 is very high for october ? Could you please tell me you spi settings with frequency ? ( screenshot please ?) yes 251 very high...have 10 fans cooling it and still have have amps...my spi volts are 3.3 and the freq is 201442 after running it all nite...pool reported as high 723gh and cgminer avg settled at 714...thinking about trying the next step up or 261 but idk...amps are pretty high on one board You are my hero  1) have you changed the settings of the individual die (more volts ?) ? 2) or just general spi ? (in addition to frequency)? 3) How many amps and watts marks every single day? With a cooler master V850 can set the miner to 251 according to you? Now I have 666 average with 231 setting (3.3 spi and 256 k freq) with october jupiter and 4 45 degrees fans and 1 megaflow yes i've been tuning individual dies since going on 251...been a struggle but Nil's graph has helped me tremendously...just now got it down to .38% and i hope it says that low..might be lower if i could disable the core that get 160hw errors an hr but oh well told you my spi settings...tryed your 256k freq and i don't think it helped, but i might start trying diff. volt n freq next as i think i got the die volts locked in almost 3rd...i don't understand this question...but i'm on a 1000w seasonic plat. psu, but you might be able to swing it if you keep the vrms cool enough |

Hi all, for some strange reason i gave a go for the wizkids version again. Now driven with 315-setting, my wattage on bertmod shows 435 and average hashrate on poolside 470-480gh/s. This is great but I wonder why it didnt show this before. Perhaps i different settings for better for the 3.9.0 and some for 3.8.5, dunno.. Im just happy =)

Does the wizkid's cgminer version work also for october miner? A part from disabling the flushwork entirely, are you aware of what other changes in the code this custom cgminer version contains? |

I found that lowering those values, AFTER adjusting the individual die-voltage settings for optimal performance, resulted in slightly better GH/s performance,better WU, lower HW% and much lower watts! before spi freq/v change: OC: 231 spi freq: 201 kHz (default) spi volt: 1.95 V (default) Avg. Hash Rate:663 Gh/s WU:9216 HW:2.3% R:1.4% Watts: +- 755W after spi freq/v change: OC: 231 SPI freq: 170666 Hz SPI volt: 1.80 V Avg. Hash Rate:677 Gh/s WU:9459 HW:1.6% R:0.8% Watts: +- 715W BTW,having the same Gh/s results with 241, 251,..(and counting) with the only difference: more watts per Gh/s |

@Ghrindy
Is the lower spi value test the same lengh as the higher value? I'll give it a try
EDIT: tryed it for just a bit...think it made my rejects way higher...was upto 2% from .5% Think i'll stick with 3.3v spi still trying 170666hz now thou
EDIT #2: thxs ghrindy looks like 3.0v spi and 170666hz netted the the best results so far...i got .2% rejects n .29% hw gona let this run overnight n see how good it is...getting 700gh/s on 241

Does anyone know how to switch on the other 4 switched off vrms of the 8 vrms oct asic baords? i think the key is to have about 60 bis 68Amps per asic DIE to achieve the 230Gh/s per asic, and 60-68 amps are to much for one vrm: Now Im running 33-34 amps /vrm. Total power 441 watts, 479GH/s  when i understand it right, the nov units have 8 switched on vrms from ericson per asic but not from GE? |

HI all
315 was just too much in long term I think, perhaps the powersupply reduced current or asic itself went to some "protection" mode, I noticed that unit was hashing just 388gh/s and had to reboot. One asic had just 24amps/vrm x 8. I did boot it but this time to get it hashing was tricky as hell (pardon me). Almost every attempt made fault 96 etc. Or some other things. But now its back at 305, with 3.9.0 and going 459 again.
I dont know any code-changes etc. for wizkid version as somebody asked.
I dont know about others but vrms on mine november are bmr464 (or 646 dont recall it) from ericsson.

Hi all,
Seasonic Gold 1250W PSU seems to dislike overclocking.
The PSU shuts down immediatelly after cgminer restart. I think its some kind of overload protection.
So, what PSU should one buy for a November Jupiter? What pSU are you running?
I thought about a Corsair 1200AX or a 1500W Silverstone.

well by far my best result...241 with 696gh/s and .33% and .14% rejects and this has been run for 24hrs so its solid...just in case someone calls bs here is screenshot think i might play around more, but this time i wrote down my settings so least i'll be able to come back to it...I don't think there is room for improvement but I'm hoping for .1% hw wishful thinking i know hehe  |
