Factors of 1000 aside...it still seems like 13.5¢/kWh to me.

A couple good rules of thumb:
The fewer connectors the better. Every splitter/extension/etc. adds another point of contact which means more chance of extra resistance and/or arcing and therefore more chance of fire/excess heat
Never use SATA power for anything other than SATA disk drives. Use molex or PCI-E 6-pin to power all of your risers. Stick to one molex chain for every two risers.
Now as far as using splitters to split 6-pins into 8-pins, and 8-pins into dual 8-pins, etc, you should keep a few things in mind. Every 6-pin is good for up to 75W and every 8-pin is good for up to 150W. So let's say you have two cards that each draw 125W. Let's say they are getting ~50W out of the powered riser. In that case, each card needs an extra 75W. You could split one 8-pin into two 6-pins and rest easy. If you split a 6-pin into two 6-pins then you could be loading the cable 2x over spec. This should be no problem for the PSU itself as long as you have enough amperage available on the 12V rail. You probably have a single 12V rail anyway, so as far as the PSU is concerned, it's not working any harder. The difference is that you are going to have double the amperage running through the wire between the PSU and the video card. Now a wire's amperage rating depends on a lot of factors including diameter, length, and how tightly packed/how much air flow it is getting. If you have short, individually-sleeved wires running in front of your intake fans you are probably fine. If you have long, lower-gauge wires with extensions, all zip-tied into tight bundles packed up against other current-carrying wires or bundled into mesh sleeves you are going to have higher resistance and bad airflow - so that's bad. Basically, as long as the wires stay cool enough, you're fine.

In a day I will release new version. More speed. About 200H/s on stock Nano. Hope it will finally stop this crazy speed racing.
have the rx 480s and the r9 390s reached the max.  Yes, what about your favourite 390 cards?  So I reached 100H/s on my favorite 390 cards but it can show even more speed.

Just got a sudden random burst in speed on my two modded 290s for a minute lol They were normally doing 140-145 and then this happened  Then I realized I had just LOWERED the core clocks on them to 1100 cuz I saw a couple non-new-job-related rejects (was running at 1125 before). Watching it now I am still getting some spikes up to 165+. More tweaking must be done... |

Too early for these two since v5.0 isn't published yet. But it will happen, no "worries".
Linux version doing 120 sols/s per RX470/480 with very little power draw (~100w per gpu @ the wall). Good luck matching that. 👏👏👏👏👏 pound that chest!! Ermmmergerd I've got the fastest miner. I'm gonna get an extra 100% on my 3$ a day for the next 12 hours 😂 Competition brings out rare sides of people. Ugly if you ask me. But as "they" say it's good for us. As far as an example on how not to be humble this should prove worthy! SilentArmy anything but! More like whinymilitia if you asky me. BR What did you expect from a user with this track record (see below) of calling Claymore a thief and whatnot. A Linux marxist on top of that. Worst combination. Examples: This makes you wonder how much of other people's code Claymore steals without giving credit.
Other of his binaries are "packed" to avoid disassembling. Gee, I wonder what he is hiding.
If i had to guess, either the licensing is being fixed or code functions are being rewritten or binary is being packed to prevent further auditing. Take your pick  After throwing this at Claymore, I am wondering what this guy is still doing here? He also said this about Claymore: This isn't a question about the fee. This is about outright stealing other people's code and not giving credit where it is due.
Sounds good, right. A person driven by principles and fairness, or not? Oh wait... * The ability to remove (or share with the XMR dev fund) the (5%) Claymore fee (by appending ":Claymore" to your workers)
EG: ADDRESS.PAYMENTID.WORKERID:Claymore (Personally, i think that one is quite important as the XMR dev fund needs help)
5% is daylight robbery!
Hey, Hotmetal, so you POS really proposed that miners and pools should defraud Claymore of his 5% dev fee for the XMR miner in 2014 by stealing the funds mined to his worker? You seem to have no problem stealing Claymore's money for his hard work. And you accuse him of theft? GTFO of here. Who's next?! I'd like to know what miner he is using to get those hash rates. Obviously he is not using Optiminer since it has a 15% dev fee, and 5% is highway robbery. It seems I must be here all the time, as soon as I decide to take a break, something interesting happens Ok, I did not check this new Linux miner, but it seems it's faster than current version of my miner, at least in Linux. So in a day I will release faster version. - Why you release faster miner? ? ? ? ?  Now we all must pay more for electricity and we will all mine same coins anyway, so much less profit!!!!!!!!!!!!!  Don't update speed, now power same as eth miner , you earn more in 1-2 days and pay more electric forever because everybody will update miner then profit is still same Nailed it! |

Why you not work for free so I can make millions too?!?!?! You are a thief!!!!!!!!!!!! - Why no Linux version? ? ? ? ? ? You could make millions with big farms which all use Linux!!!!!!!! LOL!!!! New invasion in 3... 2... 1... There is just so much fail in this post. Where is that Star Trek dude Face palm gif I think he was being sarcastic and predicting the whining coming to this thread in the near future. EDIT: Also, this...  |

I think in terms of speed claymore and sav5 are almost the same, but with share finding, I can conclude that claymore does find more. I tracked all the shares with SA5 and compare it with the logs on claymore miner and the difference is 27% for 24 hours.
 I'm seeing the opposite. |

Tried out SA V5. On R9 290s the Sol/s seem to be the same, but it is more consistent (staying between 290-295 instead of fluctuating between 285-300 across all 3 cards). Also no dev fee. There is hardly any CPU usage, either...and the GPUs are also running about 5° cooler. Seems to get max performance with instances=2 SilentArmy V5, I=1 https://i.imgur.com/AMhUwBb.pngSilentArmy V5, I=2 https://i.imgur.com/jv0hhNx.pngSilentArmy V5, I=3 https://i.imgur.com/woOeyFT.pngCPU Usage Comparison  GPU Temperature & Usage Comparison  GPU Memory Usage Comparison https://i.imgur.com/UNlnWPh.pngWhen will we get mentioned nvidia version by Claymore?
SA V5 works with nVidia. They are getting about 70S/s on a GTX 1070. Only works on Maxwell and Pascal cards. |

Don't be so wrapped up in Sol's that you waste power and actually make less money with more hash. Unless of course it's mid-November in Canada and you would just be running the baseboard heat anyway (and getting no Sols for it) |

Confirmed issue with rejects if you specify different values for "-i" parameter, for example, "-i 1,2". Will be fixed in next update. Speed improvements will be included too  |

What cpu should I buy to improve my solrate?
I have now celeron g1840 and my best rate is with -i 0,
with -i 1 is less and with -i 2 my rig freezes.
Higher "-i" have no impact even if I choose only one card with -di parameter :S
i have rx 480 rx 470 and r7 370
I have observed the same scenario and would also like to know the answer. Will Pentium help? (I guess no, but maybe latest skylake?) Will i3 be enough for 6, 7 card rigs, or we have to go i5? I haven't heard anyone with an i3 complaining about 100% CPU usage, so an i3 is probably ok...i5 for sure. I would stick with haswell socket 1150 chips though so you don't have to spend extra on a board and ram...just drop it in! My friends has i5 and his rig with rx480 hangs too on -i 2 intensity.. Which gen? And how many cards? |

@Claymore
looks like some sync related bug - I've got a mixed rig here: it has 370, 470 and 480s.
If I run different intensity (2 for 400 and 1 for 370) I get about 15% of shares rejected.
If all is set to "-i 2" - no problem, rejects below 1%
What rates are you getting for your 370 and what clock settings? It hashes 38-41H/s I'm now running stock 985&1400 (since v3.1 it became extremely unstable on higher freq, was running 1080&1500 before) Try 1375 on the mem. The range from 1376 - 1500 uses looser timings, so it's probably worth the 25MHz drop. |

Any 290/390 mem straps modding easy to follow tutorial around? too bad there's no mem straps editor like polarisbioseditor for hawaii Hawaii BIOS modding looks like a bit of a clusterfuck. I just modded my Gigabyte with Elpida ram, and it went from low 80s to high 80s. I also have two XFXs though with Hynix memory and they are already doing 95-100 without any mods. I'd like to try modding those too but I still have questions and I have been researching this for about a day now. Only place I found any info though is here and it's not exactly straightforward: http://www.overclock.net/t/1561372/hawaii-bios-editing-290-290x-295x2-390-390xThere are some premade BIOSes from the Stilt, but they are for reference cards only. I'm not sure if they are locked into specific core/mem speeds, or if you can still tweak with afterburner after flashing. It's not very clear. http://www.overclock.net/t/1561904/mlu-bios-builds-for-290x |

Does anyone here know how to get past the opencl error 0 #101 issues? I'm running a pair of older 6970s, and with every version so far I've had these errors pop up, one for each gpu. Then the miner proceeds to sit there and do nothing at all, or BSOD my system.
Sure, you just need to solder some more RAM chips onto your card and you're good to go! Seriously though, it's time for a new card. http://www.anandtech.com/show/4455/amds-graphics-core-next-preview-amd-architects-for-compute/3Wow that was some really easy shit to say just now, yet that info was so very hard to find. So to be clear: ONLY GCN cards are supported. Got it! Thanks.. Cryptonight, I'm comin home baby :-D Actually, he says it right in the OP and in the readme ...
This version is for recent AMD videocards only: 7xxx, 2xx, 3xx and 4xx, 2GB or more.
...
That said; I did see a post on the zcash forum I think where someone managed to get a 6990 working, but it was only giving him 2Sol/s, per chip. So it is possible to get 1GB cards working, but not worth it on anything pre-GCN. There is hope for 1GB 7850s (and maybe even 77XXs), but again...not supported. |

-i 2 uses more VRAM than you have on those cards. Use -i 1 |
|
|
|
Those cards seem a little warm, don't you think? How did you get 9° on the CPU? Is that your ambient temp? |
|
|

can some one with 7850 or rx 460 or r7 370 post results with claymore latest build please ? did they got also increase in hr or still stuck at 30 -38 h/s ?
Here are my results from an R9 270 @ 1000 core / 1375 mem, using -i 1  |
