The problem here is the memory bandwidth - you are going to see the same for 480
So hitting this limit you can ether go dual miner way and utilize the board to its max or drop GPU voltage and/or clocks to see if you have same hashrate
Basically you can hash at the same speed with less power used
So it was all about that 512 against 256 mem band? I guess there will be no cheap 290's anymore... Not exactly - of course raw bus make an impact but its also dependent on algo - I think dual miner will be better for nv vs amd - we'll see if it happens in near future |

So the target for the 1070 mining is not to increase its hash rate, but to reduce the power usage and higher efficiency.

well in the end i'm a bit disappointed about the consumption, all those new gpu should run at a level lower than 100w, not still around 120-130w which is the same of some old gpu if undervolted
i hope that with the correct undervolt they might run at 60-80w
Had pre production board tested just now - at 100w in nvismi (it won't go lower in linux with that pre production board) it does.. the same 26.7mhs So there you go - hopefully we'll see windows driver at release with support of 2mb tlb fix and will be able to underclock lower - or utilize the perf for dual miner |
|
|

smi-tool should work on linux as well.
Found where you can set it in linux but dont have a card anymore - maybe next week - but im sure you can lower power draw with reasonable loss in perf |

Ok folks - I have a bad news and a good news - we won't see 40mhs on 1080... but I've tested 1070 today and for some reason - it does at 125-130w... 26.7mhs - so overall its very reasonable to buy if you consider price and resale value - its definitely better then fury nano (considering other algos
The only problem its in linux now and I dont know when they get wddm 1 driver working and whats happening with july release of Win 10 and wddm 2
oh finally a good news, so 27 at 130w, do you have proof of the wattmeter? 27MH at 130w is very good, but apparently the nano is doing somehting like 20-22 at 80w, so it's not worse at all... still they will be pretty expensive, so i would avoid buying right now, you can buy a 970 for cheap(230 euro, used) that does 20.5MH/140w Its nv-smi - didnt have time to catch with wattmeter - but thats stock - i think you could go lower with power target as you do with 970 can you try to set tdp at 60% with msi afterburner? not sure if recognized yet, and then measure again with smi smi is pretty accurate, but there is a 5% error, for example in my case it say 135w mining ethereum at 20.5MH per 970, but it's actually toward 140-145w maximum vaulter, MSI afterburner 4.3.0 beta should have support for 1070/1080. Any chance you could try it? I can try it but not for ethereum - this perf is on linux only - there is no fix for windows yet (low hashrate) And i dont know how to change power target under linux But comparing with 970 i do get 140w with the same settings where i get 125w on 1070 at stock settings |

I'll post an undervolted one later
Thanks a lot! can you also post the number are you getting with these in terms of hash at clocks you use and power draw - if you did measurments |

Someone had a review unit they posted some ETH hashrates on - it was..... VERY VERY underwhelming, a 970 outhashes it.
Not sure how much of that is "new drivers not optimised for OpenCL or CUDA compute yet" and how much of it is "archetecture changes made it work WORSE on Ethereum than NVidia cards already do"....
they perform surely better on any other algo, due too low consumption and better hash, so i think it may be true that it is just a matter of bad optimization, or lacking of something necessary genoil said that their potential could be around 40MH, for the 1080, which would be an instant buy.....but anyway, still too pricy for my taste The maximum of the 1080 is 40MH, just like the max of 290 is 40MH, because of the bandwidth of 320GB/s (simply divide by 8KB/hash). I've heard through the grapvine that Pascal will be able (but does not yet) support (TLB) page sizes of 2MB and 8MB. When this would be enabled, we might finally see hashrates up to copyspeed (40MH) on NVidia. What we've seen with current drivers is much less; 650KH/s on Win7, 6MH/s on Win10 and 24MH/s on Linux (OpenCL).

Can you tell us a bit more, about the rom?
+43.75mV VDDC. Maximum TDP has been raised Power limit has been raised TDC limit has been raised Fan profile adjusted Slightly different timings. So what is this rom exactly in terms of parameters - I thought it was undervolt one?
Check above.. Nope, this is not an undervolted one. With an undervolt it is impossible to reach +32-33Mh, let alone 38-39.. (Ethereum). Do you have a version of this Bios that will work on a Asus r9 390 strix?
Your work is much appreciated!
Sorry i don't, as i don't own that card  Hi Eliovp,
I tried your ROM but it shows the same effect. I was able to change the core to 900mhz but once I started claymore's miner, the whole system crashed.
I really wonder why no other experiences this issue. What's your program to display your remote desktop? I use ultraVNC. I somehow suspect that the system still uses the GPU to render the remote desktop and causes the issue. Again, once I use internal graphics, no core/mem clock is shown in afterburner and I can't change the core to 1000.
Before I flashed the 75/75 rom, I just let it mine with the -100mv mem@800mhz bios and it worked @ 22mhz. Of course, I want to reach the 30mhz...
Do you think it can be due to asics quality?....
Talan, From what i read there. (System freezing) You have a power issue. I've got over 100 Nano's, there's isn't a single one that can't handle 1000 core @ -100mV VDDC. Obviously 800 core will run fine, it consumes practically nothing :p If you raise your core clock, your power usage will go up. And not by a little, it will go up a lot if you compare it to 800 core clock. So again, you're experiencing power issues. How many nano's was that? 2, 3? What kind of power supply do you use? How did you connect your PCI power cables to your PSU? (2 on the same rail can cause it to crash..) Have you tried just running 1 (1 connected to your motherboard "without a riser")? What kind of motherboard is that? H81 pro btc? Molex connectors connected to the motherboard if you use non powered risers? Or if they're powered risers, than don't connect those molex connectors.. I can sum up so many things.. you'll have to figure out where it's going wrong mate.. Greetings! Can you mod for an undervolt one - that is especially important for this power hungry r9 390? |

Talan, Thx for that register dump. Now try this one. LinkFlash it, completely shut down your system (Turn off the electricity!), completely remove driver (DDU), reinstall driver, remove Afterburner profiles, run afterburner and slightly go down on the core voltage (steps of -6mV) This one has -75mV VDDC and -75mV MVDDC. so basically you can still go to -100mV if you lower your core voltage in afterburner to -25mV. Your system will be already booted and won't be going crazy like it is right now. If this works, let me know, i'll lower the memory voltage until you hit the sweet spot. For all you other guys out there. Here, R9390Nitro With Backplate modded rom that i'm using. This rom will make your nitro into a power hungry beast so please be careful. First run stock clocks(after the flash), if it's ok, raise your core voltage with little steps (+6mV). DO NOT flash this rom on any other R9 390 brand. It will definitely screw it up! So ONLY R9 390 Nitro with backplate.  LinkAlso. This is a modified bios. Yeah...
This will void your warranty.
I am not responsible for a failed bios flash or damaged card resulting in the usage of this bios.
By downloading this you are agreeing that you take full responsibility for using this bios and hold no liability to me or this site.
If you feel uncomfortable, than don't.
If for some reason you do brick your card, because you probably didn't read my instructions to careful :p and you can't afford another one, than don't..
If you're happy with everything as it is right now, than don't.
If you're like me, and you want to get the most out of your GPU's. Than yeah. go ahead..
This goes for every bios i share.
Greetings! So what is this rom exactly in terms of parameters - I thought it was undervolt one? |

Decred sp-mod #9 does 3.3 ghash on the 980ti. 2.7 for the 1080 is low
yes but with what consumption? 1080 can do 3300 with oc too, but consuming only 180w, the 980ti will consume like 250 or more Sources? Hypothesizing is fine, but mark it as such. Don't state something as fact unless you have sources for it. mmmmm 1080 nice
is the above run at stock?
wondering what the power draw is ? if you don't have a watt meter, what is the percentage of TDP that the card is averaging ?
it has double the hashrate of a 970 with the wattage of one for decred, which is really good, but it cost 3 times more, not worth it for the moment, also decred is bad to mine versus eth Decred is so bad right now that it makes less profit than mining lyra2v2 with a 750Ti or quark with a GTX970, that bad  Yup, still getting hammered by the Claymore AMD miner... If only Nvidia had something like that. Real test is going to be what a 1080 gets in Eth with the fucked up memory issues since the 1080 uses a different type of memory and bus. this guy is an insider, he tested both 1080 and 1070, they perform better than any gpu right now on any algo minus ethereum and this without counting optimization and proper drivers Not sure I believe 'all at 180w' unless they have a watt meter. A lot of people thought 970s wouldn't go over TDP or close to it. Doesn't show clock speeds or TDP either. Currently I hear the 1080 throttles in games too at stock speeds, doesn't mention whether or not the fan profile was increased or if that happens under prolonged mining. 970 it's actually under tdp, those that have it above, don't know what power limit is and how to use it on msi afterburner, and or they are buying 8+6 pin gpu with again PL at 100%, which push the wattage to unnecessary level i'm now at around 125w for 19.5MH with a 970 There isn't a correlation between power connectors and wattage besides on 750tis which generally don't come with a external power connector. I have some 6x2 EVGAs that use less wattage then Asus cards with a 6+2 connector. It's all based on how they're binned and that has nothing to do with power connectors. You can't trust reported numbers on the PC itself, you have to use a watt meter. They've been proven wrong time and time again. i have used both, and wattmeter display the same thing, unless now you want to say that even my wattmeter is broken actually the wattmeter will report only the full consumption, including the whole system which will drain an additional 50-70w, so it's not that good to measure with the wattmeter the correct wattage of your gpu result are the same 135w at 20.5 mega and 125w at 19.5 mega for each 970, the smi thing got boosted, it's pretty accurate now What are your exact settings for 970 (including afterburner and cuda intensity for miner)? |

With GPU Pascal ( gtx 1070 - 1080 ) ccminer work on windows 10 in future ? .
Already works fine with win 10 I use 80 build (but not cuda 8 - that gave poor performance results) with following results - 32mhs quark and 16mhs lirare2v for 1080 and 24mhs and 14mhs for 1070 So ~23%-26% increase from 970 to 1070 assuming OC. That's pretty poor so far. We still have a piece missing, power consumption vs the 970 or kh/power ratio. right now in ethereum my rig has 145KH/W if hash/power ratio worth it i will consider buy some 1070  I didnt try 1070 on ethereum but as fro the 1080 its 120w at 23mhs on eth as for 1070 I think it will be the same or less for eth in terms of power and i think it will be around 22mhs for 1070 as for quark its 130w at 24mhs lira was 120w at 14mhs |

Claymores Dual Miner.
Thanks I will check it out. CDM mines ETH and DCR together. I use the ETH only mode, and CDM can push the 390 to near 30MHs. I used qtminer before this because of the Stratum mode, now it's all CDM for my 390 rigs (149.5MHs@5x390@1290w-1350w@-100mV/1028Mhz/1500Mhz). Quite slick this miner, and its has many bells and whistles like failover, monitoring, solo-mode w/o proxy and it's Stratum compliant too. I will be attempting Eliovp's Nano mod for my first Nano rig (I am still trying to get an afternoon off to do this). And combined with CDM, I think we have a winner for the highest hash at lowest possible wattage, amps for ETH mining. Have you tried to mine with 1200 memory frequency. For my XFX 390 cards, there is no difference between 1200 and 1500MHz with 1050 Core. WI'll try it out. My 390 is MSI so I think no issues in underclocking the memory mhz. Thanks - works like a champ! Try 1125, 1200 is a weird number in case of your timings. 1500 or 1375 or 1250 or 1125 is more like it Eliovp.... done -100Mv/1050/1125.... 5x390=151MHs. Do you happen to have a ROM mod for R9-390? Btw, I have my Nanos in, I haven't spent time on the applying your mod yet. My first attempt gave me an error "GPU not found", when I ran the atiflash command with the parameters in your guide. I stopped there and will spend a longer weekend to do more reading. Any ideas? https://bitcointalk.org/index.php?topic=1424132.msg14946664#msg14946664Will comment on that later mate, or perhaps help you out, but gotta go now, already late again for a meeting. I have a rom for a 390(reference "hard to find") and will share another one that's running on my nitro's as soon as possible! Greetings! Hi there - can you share the r9 390 sapphire nitro rom with us - that will be useful Thanks in advance! |

Paper launch is NOT "available" - though NVidia paper-launching the GTX 1080 less than a month before actual availability (presuming they meed the announced May 27 "available for sale" date) was semi-impressive.
I agree, I only wanted to point out that we will know by 1st of June for sure I have a feeling that top Polaris will still outperform 390x. Hoping for a nice 480x. According to the following link, "480x" is just 5% faster than the 390x. http://videocardz.com/60253/amd-radeon-r9-480-3dmark11-benchmarksI think we might be a bit surprised that new amd polaris parts will look similar to 970 in terms of mining perf 390 and nano will look better in memory dependent but will they be good from price/watt/perf standpoint - 1070 looks definitely better from resale value - so overall might be a nice part but yes - end of year parts from both vendors will definitely outperform current parts in pure perf but perf per value - that is the biggest question... |

Numbers for 1070 (maybe there will be some improvement but dont expect much with optimization)
all results are without overclocking
Quark 25000 at 140w
LiraReV2 14000 at 120W
Decred 1900 at 130W
Dont have ethereum yet - but expect 20-24mhs at 120W

windows 10 is okish too for those card with the right drivers?
No, you can't mine etherum with windows 10. Im on windows 10 x64  , It will never be possible mining ethereum with windows 10   . Should be fixed after July win 10 update |
|
|
|
Genoil is it really only 24Mhash for 1080? Cant be  It is 24mhs at 140w that is for 1080 - the big question is 1070 that will be better choice for mining anyway (or even other cheaper Pascal based GPUs) |
|
|
|
so someone bought the 1080, for testing how the hashrate is in all the algo?
Neosrypt and etherium needs clarifying - maybe will be bound to linux on release - cant tell the numbers yet Not working at all ?! Working - but for neoscrypt - I need to test linux - and for ethereum its linux only - performance is low on windows at the moment... |

For 1080 Decred 3200 Lyrarev2 16000 Quark 32000 Neosrypt and etherium needs clarifying - maybe will be bound to linux on release - cant tell the numbers yet All is at 180w 1070(maybe it will change a bit) Decred 2300 Quark 23000 At 120w good, this of course is without all the tweak that need to be done, and not to mention proper drivers, i can easily see 40mega on quark for a 1080 and 30mega for a 1070 those gpu with those number on decred, can make it once again profitable with lower consumption, pretty beastly, i can not wait to make a rig with those Dont expect much more with quark - overclocked it was 35000 - maybe with private kernel it might be more overclocked |
