Hey Bobben2! Thank you for your detailed explanation. What you wrote will definitely work! I do it a little bit different. I modify the rom in a hex editor and change the voltage entirely. In other words, i do not change the dpm tables, i just lower the entire voltage by -100mV (for example) so that the controller itself will automatically give the voltage that is needed. In this case, a specific clock won't give you issues as the controller will adjust voltage for what is needed. What you did, as said before, will definitely work, but is in a way a little more intensive, because the dpm values won't be set automatic, the controller will use what is set. In some cases this could go wrong, for example, the card will need a specific amount of voltage, but the dpm value associated to that clock won't be able to give enough.  Regarding power, in this case it will use less power in comparison from what i do I'm glad you worked things out! As said before, i'm still working on it, my target is to achieve the same results as the Stilt did with his released hawaii roms from a few years ago. Will keep you posted in this thread as well! Greetings! Hi ldw-com Are you there? I am trying to locate the actual voltage table so I can offset the values as per your suggestion. The evv pointers are supposed to point into the actual voltage table (evv value XOR 0xFFFF I believe will give the offset into the powertable in the bios where the voltage value is stored. Or--?) I am doubting this logic for 2 reasons: byte offset whereas the actual voltage values need at least 16-bit storage. The actual values I find by using the above logic are "all over the place". Suggestions? Hey Bobben, ldw-com is me when i'm at work (just so you know) if you open your rom with atomicbiosreader you'll get a .txt output, just scroll down check under data tables for "VoltageObjectInfo", the offset is there on the left. Open your hex editor and go to that offset. If it's there, it'll be like so 8D 00 "YOUR VALUE HERE" 00 for memory voltage it'll be like so: 8E 00 "YOUR VALUE HERE" 00. To change that value to -100mV you'll need to add F0 where i typed "YOUR VALUE HERE" :p .. If you need extra explanation on how to calculate that, just ask :p In some cases those values do not exist and you'll need to add them yourself. In other cases it just isn't possible to edit memory voltage (like my 390 nitro's) <-- check my Nano thread "last post" Greetings! |

Tried it again thoroughly step-by-step, like youŽd suggested - same result as above. IŽd uploaded my original MSI Nano BIOS here, if you are interested. Maybe you can find any differences. Ok, will check it out tomorrow and will mod core voltage to -100mV and mem voltage to -100mV as well. Greetings. Try this one, this should work perfectly Eliovp/ldw-com- Did you notice any difference in the rom file that you edited for Termie? Haven't found a rom that works with my Gigabyte Nano yet, but I still need to try the -106mV, -112mV and -118mV ROMs. Nope, not really, they're basically all the same. The offset for core voltage vddc, and memory voltage mvddc can't be found in the roms, not my stock rom, not yours or anyone else theirs. I have to add those offsets myself. So it basically stays the same for any nano rom. Further, i have some other news for my 390nitro rom. I tried, and tried and tried to modify my rom as much and as hard as i could (regarding memory voltage). There was no way for me to add that offset, vddc offset is already included in the rom, so editing the core voltage settings is not such a big deal. Anyhow, it seems that MVDDC is fixed on my 390 Nitro's, the MVDDC controller has no data interface so can not be programmed by ROM or driver. I didn't want to believe that, but yeah, Sapphire raped me on this one :p This does not mean that this is so for other 390 brands. I have an XFX one as well and that one is perfectly editable. Anyhow, i changed the vddc value to -100mV and it runs like a baby now Still screwing around to get the same results as The Stilt did with his mods for the 290's. I'll get there! Greetings! |

If you mod the AMD R9 390 memory controller voltage or the memory voltage with -150 mV, how much can you save at 1200 MHz memory frequency?
I will write my findings for the 390 mod later Personal things are taking a lot of my time right now, will definitely report back! Greetings |

Got over 500 Configs/Cards active at this moment. Thx everyone for their submissions! Appreciate it! Keep em coming! Will update the website as soon and as regular as i can. My offer is still open... Oh btw. If there are developers out there that are willing to help, send me a pm. This account or my main account "Eliovp". I'll throw some btc, obviously not much because this is completely ad-free and done in my free time. But looking at the traffic that is generated, this website has potential (4-500 clicks per day) Greetings! |

Without mod, according to the OP:
"My nano rig (6 x Nano) would do around 170Mh/s "give or take" on Ethereum (stock settings) while pulling 6.8Amps from the wall!
So that's around 1500watt."
thanks - need just that confirmation before clicking that ENTER button to purchase some of these Nanos. Btw, I know that OP using Sapphire and that works with mod, would other brands like XFX or Gigabtye, Asus be worth trying out? I noticed there is no MSI for Nanos on Amazon or Newegg. Damn shame, MSI makes good stuff. Hey Citronick, Doesn't matter what brand you choose. They're all reference designs anyway. The only thing that differs is the Sticker on the fan. I chose Sapphire because i got the best deal with them. Greetings! |

usefull information to share with you... I have a lot of GPU (nano of course) that works good with -175mv but 20% works only with -135mv. just one gpu in 6 gpu rig and all system is not stable and freeze. So... start from -135mv always! and than... maybe... lower I lost two nights... I should have mentioned that earlier. I haven't had a lot of those problems though, i must be lucky i guess.. I had a few that were giving me some issues, like 2 out of 100. (I flash my cards remotely and only hook up a screen to install drivers..) |

That is correct Regarding the 390 rom, will update OP this week for sure! "Been updating some other things first.." In posts before you've said that you was able to change memory voltage by software on 290-series card. Did you mean memory voltage or aux voltage (vddci) that can be modded by Afterburner or HawaiiBiosReader? If first could you please explain how did you change mem voltage? Hey Rednow, I was talking about memory voltage, not aux voltage. But i thought it was basically the same as with Fiji, but it clearly isn't I'll post some results later, have had a very busy week. Greetings |

This is great, I really appreciate your efforts.
I hope to pull something together soon and your site is really helping!!
Thank you for those kind words! I have updated the website a bit. Cleaned up a lot of things, not only visual things. For those that have visited or/and still are, you'll see the difference immediately when checking configs. Also, the submission form has been a little modified. (Will re-write that later). As for my to-do list, been finding some extra time here and there, so it'll get there eventually :p Greetings! |

Say maybe ASUS and Gigabyte > XFX and Sapphire?
There is no difference between them, the only difference is the stick on the card and the after sale service. That is correct Regarding the 390 rom, will update OP this week for sure! "Been updating some other things first.." |

Is there any progress with your 390 mod? What is the power consumption after the memory voltage mod?
Still working on that, well, it's ready, but seemed to be having some issues after a while. System froze after 14hrs. Doing a retest as we speak. I updated the op with new roms for nano This time i added -100mV, -106mV, -112mV, -118mV and -125mV memory clock. Core clock is still at -100mV (if you have issues with this (some cards seem to be behaving a little stubborn (Mostly When a Monitor is Attached!). If so, just pump up the voltage with +6mV in afterburner or Trixx or any other tool you use. Link for this package in OP. Greetings. First, thanks for all your great work, and your willingness to share it! Second, have you done anything with disabling ROPs and, perhaps, some of the CUs (I know they are not all needed for the ETH algo)? Disabling ROPs would presume a headless miner, but if you get past a couple rigs, that's probably what you're running (like me, for instance . There may be some nice power savings there! -Best Care Hey, You're welcome I haven't really spent any time on that though. Basically because all my rigs are headless and have never given me problems with that. I can reboot, shut down, restart and they'll run just fine. Regarding the power savings that i could gain with that, maybe, i could check it out and do some tests. i'll report back |

not profitable for me anymore, diff to high and price lower than before
If your electricity price is high, you have to undervoltage and underclock the graphics cards to make them more efficient. undervolatage and under clock will make the mining more profitable ?? I do not think so... You will get less hash for less consumption , that is it So not true.. check my nano rom thread in my signature.. |

Do you think your roms works with Powercolor r9 nano?
Yup, should work just fine! Basically the only thing that's different is the sticker on the fan Edit: Working on my Rom for my R9 390 Nitro's (Sapphire).. will update op as soon as i'm ready and tested it firmly Greetings! What is the model number of your Sapphire R9 390. If I buy it next time, I would like to get the same one. It is the Nitro 1040 MHz. Exactly I'll probably share that rom tomorrow |

New update in OP! Also added read me for beginners etc.. have fun! |

It's kind of like the iOS vs Android vs Windows Phone discussion.. same thing :p (Although that Windows Phone kind of sucks <-- haha) Everyone has his own personal opinion about that, same goes for Windows, *nix and MacOS(yeah yeah based on unix..). Whatever suits you and makes you happy. I use all three of them, Windows @ work, Linux for some of my miners and MacOS at home. Same for Android and iOS, Android at work and iOS at home They all have something i like.  As pallas said, get the best out of it and stop complaining. |

I use 6x nano on a H81 Pro BTC board, also got one with the B95 Anniversary board.
Works perfectly on those x1 slots.
I "had" a few furies as well, also with risers, also connected with risers to a x1 slot (MSI z97 Gaming 5 Board).
Dunno where all you guys find all those issues :p
Riser perhaps?

The AMD R9 nano is the most efficient miners so far. It is even more efficient than the nVidia cards.
yes and it cost 60% more lol Than nVidia cards? No way. The nVidia cards that are on par with the nano regarding hash rate are even more expensive. Anyhow, it's true though, core clock @ 1000, even with a heavy modified bios will still use up to much energy. The holy grail setting (for me at least) is 800 core, 300 mem. Best Hash/power setting. |

Win 10 is rock solid over here, fastest os regarding mining i ever used. No shit with installing gpu drivers when having more than 5 GPU's. It just works.
Have you ever tried installing more than 4 video cards under Win 7? I had a 6 card rig working fine on Win 10 but reversed it to Win 7 in hope of getting better speeds but problems immediately arose when some cards refused to work. Does Win 7 has any limitation to the number of video cards simultaneously installed? Yup, 7 gives issue with 5+ cards. There's a 6gpu mod flowing around, that works but it's not going to give you a speed increase. Well it didn't over here... |

Newest Rom for Nano's. Been Stable for 48hrs. Even more power efficient! Stock Core clock: 800 (perfectly able to set back to 1000 with AB or Trixx) Stock Mem clock: 300 Core voltage -100mV Mem voltage -150mV DPM values changed Timings modified. LinkFor those that'll use it. Have fun! Greetings! |
