never said anything about running crap windows  squeezed a few more MH out if it with some BIOS hacks   Interesting.. What clocks have you set? I assume you expanded the last strap to be able to run in a higher timing than 2000? 14.04? Greetings! Edit: just saw your post in the other thread. Guess i need to test on linux ;-), thx! |

Yep...running custom BIOS on ubuntu 16.04..29MH @ 120 watts.
Let me step in here. There is no way to pass signature check 'yet' .. So a "custom" bios <-- Not possible (yet) Reference: HereTrust me, i've tried.. several times, thought i'd cracked it but no.. it's not yet possible. The only thing that is possible is to modify the amd drivers to be able to go higher than 2250 mem. Which i have done and which i have proof of. Here:  I would love to see some proof of that 29+ Mh.. Greetings |

Just for the sake of it,for 5 390x and one 380 card he wanted 0.38 BTC.While i appreciate his work and probably his miner is good there is no way to justify mining 1 month just to get this miner(electricity is not cheap here) . 1% fee would had been a better approach in my opinion.
Whelp, looks like we won't be doing business with you again. You gave us a list of cards - I gave you an estimate. You did not state electricity was an issue; some clients don't pay for it. You didn't even try to negotiate. You just said 'no'. Fair enough. You move on - you don't come to a public forum and bitch and moan about it. No, we won't be doing the 1% fee. In the future, please refrain from broadcasting the details of private PM's. For others: the price is tailored to your farm size, your current cards, and other factors. If you're interested in a quote, message Wolf0, or myself, and we'll get back to you as soon as possible.

Does he charge a flat fee or based on the number of GPU? Maybe he does not want your business so charge higher fee. Currently, it's based on the number of GPU's for the Eth miner - however, many things factor into the decision. Return-of-investment, electricity, farm size, current budget, what cards, etc. People who are polite and kind and are long-time customers get a deal, too. Just a small thing what directly popped up in my mind... What's from stopping people to say: i have 6 GPU's, while they have 600.. 0.35btc is peanuts for a farm with over 200GPU's.. Just saying..  |

Ok. New rom release, tighter timings. Tests have been done on 15.12 drivers which i find are the overall best drivers available. Also done a test on 16.4.1 and that's also ok. 16.1.1 & 16.6.* not. So if you have these, speed won't be the same. Before, per card @ core 800 , speed Ethereum: 22Mh Now, 23.5Mh. Power draw, exactly the same. Included a few roms in the package. Link: -Here-Greetings! |

Anyhow, got a new rom, 1.5Mh speed increase per card for Ethereum at the same power usage  , in my case, that's 8Mh extra per rig which is a lot will release it soon! Greetings! Hi Eliovp, How's the status on the new rom? Just wondering... Oh yeah :p i'll share it tomorrow, forgot about that |
|
|

yes and it does 222MH, which is almost 2 eth? no... so what's your point?
aside form this it was 132-135w at 80w each nano, which is 480 plus system, here we have 222MH at 840w plus system
Hey Amph, I modified that rom even more, it's 140Mh or 23.5Mh per card at the same rate(wattage). Further, you said, and i quote with pascal we can kill the diff for another month or two, so no need to worry
1 rig full of 6 x 1070 is currently earning 0.037 a day, and consume only 900w or less which is better than anything else at the moment I guess you miss typed there? 0.037 eth per day is nothing.. to get that you would need only 5Mh.. So yeah, you must have miss typed Anyhow, 222Mh for a 6x 1070 rig? That's around 37Mh per card. It "could" be true, but i seriously doubt it.. haven't seen any proof of that on any forums.. But again, i could be wrong. Btw, especially when only using -900watt.. if that would be true, those 1070 would already be sold out until the end of the year.. Greetings i think the nano is just a special case, it's really impressive that it can perform so well, but remember that there are other profitable algorithm, and i dobut you can do so well outside of ethereum? what about neoscrypt or lyra2v2 with the nano? that earning is in bitcoin, not ethereum, i forgot to say 0.037 btc here the proof http://forum.ethereum.org/discussion/7780/gtx1070-linux-installation-and-mining-clue-goodbye-amd-welcome-nvidia-for-miners#latestyes you can say "i don't believe it" but why he should lie? you think that he is pro nvidia, he don't care, everyone here is for the profit, also it make no sense for him to post such a guide and lie shamelessly he say that you can even push it even farther than 37, a little bit more i also contacted him and he tweaked and fixed the instability problem, so it's possible to have it stable at those rate Hey Amph, Thx for that link, i must have missed that! A quote from that post As you can see here i am doing +200 on the clock and +1500 on the memory, some notes you might find handy:
single card: +285 & +1800 is the max, single card pushes you to 37.19MH/s with Cuda or 32,66MH/s with OpenCL
multi card: + 275 & + 1775 is the max, but not stable (read: 6 hourely crashes) and pushes 4MH/s per card
multi card: +200 & + 1600 semi stable, needs more testing but this might be better and pushes another 3MH/s per card
again, these settings might not work for you, but gets you in the ballpark. So basically, he will do around 30 per card, which is still very impressive to say the least! Anyhow, you asked me for another algo for my nano's? i think the nano is just a special case, it's really impressive that it can perform so well, but remember that there are other profitable algorithm, and i dobut you can do so well outside of ethereum? what about neoscrypt or lyra2v2 with the nano? Well.. Siacoin is doing very good.. My 390's do 1200 (avarage) Mh at default clocks. My 290's do around 1100Mh My 380 does around 800 with a slight memory over clock. My nano at core clock 650! does 1100Mh as well. Consuming only 70 watt! If i crank that baby up to 950 core, it will hit 1650Mh and at around 1100 core it does 1850Mh. Haven't tested neoscrypt or lyra on my nano's tbh, Ethereum has been to profitable for me to even try.. Thx again for that link, i seriously missed that post.. Greetings! |

First of all i want to thank Eliovp for the sharing of knowledge and all the thread participants for the added infos. I'm on the -175mV rom since 4 days now and all is fine but headless boot won't work. I need to plug hdmi to monitor and it boots fine at the moment i have two nanos on usb risers and one on motherboard, one 700W PSU mobo is H81 Pro BTC and i'm booting lubuntu with claymore's on thumb usb @Eliovp: i think i have read u have the same mobo and same cpu celeron g1840 did u have issues on headless booting? also i'm on 312w reading on killawatt for mobo+3nanos with your stock -175mV rom audio and sata's disabled is that good? i thowght i'd go lower with 75watt for each nano i was expecting. i'm going to try -200mV stock soon. Thank you again good mining to all. You're very welcome! Yup, headless booting is an issue as well, but i don't really need it tbh.. Should be around 75-80W per card. It is so over here Anyhow, got a new rom, 1.5Mh speed increase per card for Ethereum at the same power usage , in my case, that's 8Mh extra per rig which is a lot will release it soon! Greetings! |

Legendary finally  CONGRATULATIONS! -- Now what? Full Legendary Almost the same register date as me i'm going for legendary with the same amount activity as posts. Don't think that has been done before Congratulations none the less! |

A couple of noob questions here.
a) Does down volting the memory system effect hash rate or just power consumption ?
b) Do ULPS settings matter ?
Thanks for sharing.
A) Power consumption (for some also stability) B) ULPS (Ultra-Low Power State) You can compare this to your television that you turn off, it goes into stand-by. So basically for mining, pointless. Greetings |

Will release a big amount of roms later this weekend. (100ish..) Greetings For which card? Nano? Mostly nano yes. Will have a bunch with different offsets. You'll see.. Will release a big amount of roms later this weekend. (100ish..) Greetings Do you have the XFX 1050 or 1015 MHz Roms. Will be interested to know how you reduce the memory timing/latency. I have the XFX 390 DD w/ backplate yes. (1015Mh version). I'll add that one as well. Will release a big amount of roms later this weekend. (100ish..) Greetings Looking fwd to MSI-R9-390 (with back plate) rom mod please.... Don't own that card mate. Don't have a register dump of it either. Won't be simple to make one
I have managed to get the -175 rom to hit 1060/300 pushing nearly 31MHs.
Anything more, reduces the MHs lower, so I stopped at 1060, and let it stabilize.
Flashed a 2nd nano to join this system, and so far so good averaging 30.xxMHs
Tomorrow, I will add more to achieve 6 x Nanos.
I hope this batch of Nanos make it to -175 rom mod.
Looking good Mine run 1050 core without any problems, haven't gone higher because i didn't want to tbh.. Good luck further! Glad you're having fun |

The new 480's could perhaps consume only 100 watts with a under volt and reach a close to similar hash rate most likely around the 23 mh mark to speculate. If things turn out to be good I will seriously consider switching over my gpus to the 480 and further build dedicated rigs on that card as it seems like it will be pleasure to do so.
Also keep in mind that a card like this shouldn't in theory cause a change in hash rates as its not providing a jump in hash rate and farms only have so much space to place the cards. So it seems like the biggest win is for the hobbyist being we pay the highest rates on electricity vs. farms. Those farms wont really want to buy this card being it could reduce their net hash if the farm is maxed out on space and their electricity is cheap enough to where they would lose more by switching over.
Just so you know, i i already pre-ordered one. From the moment they're available i'll be getting one. (one to start with). First thing i'll do, is check out that rom and see what i can do, from the looks of it, and what i've read and heard, it seems that it's fiji-like, so i will probably be able to crank it down even more regarding power consumption So this could be a huge winner.. If..... and also if...... How much did you pay for that? Haven't payed anything yet, i contacted my supplier to get one for me as soon as they can. And they will. All depends on when they can order from the main suppliers.. |

All next big gpus will be similar in memory bandwidth So perf will be similar (we will know when polaris is tested - I dont know if i can but I think i'll get it before launch - maybe around 20th of june) So its just the matter who is early and what is the price But its not pure memory bandwidth question as you all know - fury x is far from 60mhs - am i wrong? The furyx is 40MHASH in copyspeed, and you will never reach copyspeed. uhu, Fury X does around 32-33Mh (stock), correct me if i'm wrong.. |

A few more Nanos coming in today - so I will try again the elusive -175 and -200 mods - it could be batch issues - will let you know results. The -175 mods is really the one that I would like to have for these Nanos.
Btw, do you have the link for the 390 rom mod? Will it work on MSI-R9-390?
Sounds great No mate, read my post a few pages back. Only for Sapphire 390 Nitro w/ Backplate. Greetings! |

Using -150mV rom mod on Sapphire R9 Nano
Results: Clocks:800core/300mem, 657watts, 2.67Amps, 132.5 MHs, temps=59-61c, fans=19% (mining ETH mode, CDM 4.5)
Current system: Win8.1, Cat-16.5.3, ASrock H81-BTC, 1840 Celeron, 8GB RAM, 120Gb SSD, USB3 Powered Risers, EVGA1600
Notes:
1. Big saving$ on PSU - now can replace it with smaller PSU.
2. Cranking up to core clock to 1040mhz/300Mhz memclock, gets to about 176MHs but wattage and amps will increase too 1348w and 5.4amps. Temps will also rise to 76-77c and fans 49%
Next project 2nd attempt on -175mV rom mod.
It worked well on 1 x Nano (see my previous post)
When I got all 6 on same rom mod, I had issues bringing up safe mode to apply DDU. I may have given up too soon. Will try and get this going after I see how stable the -150mV rom mod runs after a few hours mining ETH only with latest CDM 4.5
UPDATE: 1. Looks like -200mV is not for me.... after flashing, power off, DDU etc.... installation of of Catalyst 15.12 or latest 16.x.x hung halfway at 12%. Rebooted cold or reset, blank screen. 2. well.... the -175mV rom did not go well too.... after reflashing, DDU, install of Catalyst latest drivers... Launching CDM goes silent after identifying the Nanos. Tried qtminer, also no luck. 3. Decided that -150mV is probably best mod for now until Heliox gives a few more ideas on how to fix issues above. Citronick, I have 3 or 4 cards that have been stable with the -200mV since i released it. the others gave up after a while as well tbh. For now i have 3 cards that are running the -150mV as they kept failing after a while as well. All the others (90pcs) are running with the -175mV rom and are stable for over a month now. A few rigs even longer, 40+days non stop. I can't explain why some seem to have so much issues with the "tough" roms as it all goes smoothly over here. Maybe it's because i have an early batch? Dunno.. What hashrate do you get with this rom?
Currently running @ 1220 core clock @ around 35-36Mh/s. 1260 gives me 39 but temperatures rise to 85degrees because it's getting hotter every day here. greetings! |

Edit, i see you edited your post.. "the programming of the kernel code" The bios is perfect. But the kernal is suboptimal... I picked up 13 r9 nanos and I think I can boost them on low clocks.. Well, no one is stopping you My next stop, shedding those rops.. "although that it seems to be a difficult job, if not impossible.." time will tell. Keep me informed about your progress Greetings! |

Keep modding. The code is shit. The competition is reducing the power/cost in the programming...
Oh, looky here, sp in my thread Welcome! The code is shit? I hope you mean dagger? What do you mean by the competition is reducing the power/cost in the programming? I could have kept this for myself, i would have (probably) be one of the few that was mining at a very decent hash rate at a rather low power usage.. (especially with nano's...) But oh well, i'm still a "You give some and you get some" person.. Edit, i see you edited your post.. "the programming of the kernel code" |

Just an extra here In case of stability. Almost all my rigs have been stable for over 40 days non stop.  As you can see, 970 hrs, over 110k shares This is with the -100mV VDDC, -175mV MVDDC rom. Picture of temperatures.  So far, amazing investment! Greetings! |
