I found a way to lower memory clocks with MSI Afterburner, even when this feature is disabled in AMD driver, so, we need:
1. Run MSI Afterburner and check that "Unofficial Overclocking Mode" is currently DISABLED
2. Set desired memory clock setting (for each card if they're different in your rig) and hit apply, save these settings at the first profile and check "apply overclocking at system startup" box. Now, if you run GPU-Z, you'll see lowered clocks at the "Graphics Card" tab, but if you check "Sensors" tab, you'll see that memory clocks remain the same, nothing has been lowered actually.
3. OK, go back to MSI Afterburner, go to Settings and ENABLE "Unofficial Overclocking Mode" without PowerPlay feature and hit OK. Now your system should restart automatically.
4. When everything booted up, you should accept terms and agreement in the popup window, and then you can check with GPU-Z, your memory clocks are really lowered now to the numbers you've entered with Afterburner earlier and will not raise to factory settings until you want it.
5. ATTENTION! After these manipulations you won't be able to do any over/downclocking with MSI Afterburner actually, if you want so, you'll need to disable Unofficial Overclocking Mode and restart your system, but in this case memory downclocking will be lost.
Worked on each of my rigs (have 12 of them), each of them have the same card models onboard (but different manufacturers), especially tried on 290x and 390x.
Gald if this will help somebody.
wow nice info, did you gain lowered temps and power usage by doing this ? what mem clocks do you have now for your 290x and 390x cards ? and what is the new hash rate |

Nvidia - no. Failover - yes, in next release.
Finally got sick of ehhminer constanly dying and crashing my miners on the regular and tried this miner out and wow ! Im in love , now getting 180mhs for my six 390 card rig that i was testing for a while thats with an undervolt of 100mv cards are running about 5 degrees hotter but each card hashes at 30mhs no lower. Also it seems this miner is smarter if one card dies the miner does not hang it just keeps mining with the other 5 cards this is good so now i can play around more with undervolted bioes going forward etc. -two things 1) All i need now is a way to use it with the solo mining proxy https://forum.ethereum.org/discussion/3513/ethereum-mining-proxy/p12) do your commands for lowering memory clock really work ? in MSI afterburner yo ucant really lower the memory clock . i mean it lets you but the clocks do not go lower when you apply the settings. For ethreum we can get better power usesage and temps if we can lower the mem clock and a leave the core alone at least for newer AMD cards. |

I got PM'd about a lawsuit against ltcgear. Does anyone have any news if one is actually happening? PM me if you know. I want to be sure that it is legit before I respond.
Not heard anything. Did you get it here or on litecointalk? If they are asking for money could be a selective scam. It was on litecointalk before it went down. I thought the hack might have been related. I'm interested in getting involved in a lawsuit. My lawyer said that for the amount that I lost it wouldn't be worth my time unless there was a class action suit. So if there is one happening right now I would like to join it. I just don't want this fucker to get away with it. Litecointalk went down...damn. There have been a number of calls for a lawsuit so I'm not sure they are related. Chris seems to bank on the 'not worth it' vibes. I am sure he will get away with it like they all do. I don't know how they can live with it. I hope he CANT live with that what he do. I lost ony under 1000k bucks. I can live with my loss..but i think some other guys invest more and now have problems  Some people lost insane amounts of money. I don't think Chris cares. Sociopath. personally i lost close t around 30grand on this scheme but i know there are folks that lost hundreds of thousands ! one guy have close to half a million shares which equates to close to 300k real cash. Not to count those that paid for hardware shipping and also the mining fee when he pretended to come back. A true Robber Barron this guy was puts the barons of old to shame. |

Hey, i use HxD and a calculator to modify the values. After that i use Fiji Bios Editor to fix the checksum  Greetings I would like your bios but its hash rate is a bit too low for me I have around 8 saphire nanos I notice on afterburner you cant reduce the memory clock on any cards not even 390s You can reduice voltage a max of 100mv of course and power tune and core clock. would this tool work on the R9 Nanos and the 390s to reduce voltage and Memory clock ? https://github.com/OneB1t/HawaiiBiosReaderor can you provide a new modifed bios that hashes at around 150mh/s rather than 130ish leaving 30 mhs on the table seems kind of a waste. |

Well i'm @ -150mV at this moment and still running stable. Will let you know when i hit bottom..
Srsly? i had no idea this could run that stable tbh and thx for the little movie ~CfA~ what tool did you use to mod your nano ? |

The Claymore new eth miner is about 3-5% faster than the ethminer. Is that also faster than 1.0.6?
I have only tested 1.0.7 against claymore's on a 7950 in ETH only mode. 1.0.7 has a different kernel but shouldn't affect speed on AMD that much. My miner showed slightly higher hash rates but that could be due to a different way of calculation. Is your 1.0.7 faster than the previous versions of 1.0.6 or 1.0.4? Do they use the same mining kernel? It's a different kernel but not faster on AMD. I had a stab at trying to bring VGRPS usage down to 64 but didn't succeed. As a nice side-effect though, I managed to make it faster on Nvidia GPUs, almost as fast as the CUDA kernel. That can be useful for people who have issue compiling the CUDA kernel (i.e. OSX, Fedora). so is 1.0.7 faster on gtx 970s ? |

using worker-name as password is better - SOME shares were counted.
But after 15min I realized something is wrong:
- PC1 (1x290), 11 shares reported from miner, 1 share from DP
- PC2 (2x265) - 4 shares from miner, 2 shares from DP
And waiting another 15min (miners stopped) didn't help - no new shares counted by DP
I'll try it on coinotron this evening as well |

and please watchdog option that would help allot. use nnCron, Create a 2 macro : 1 Kills miner process every 30 minutes . 2 Check whether the miner started every minute and if not then runs it . In the end, it turns out that every 30 minutes a miner will be restarted . Thats a waste of time , if its an issue it needs to be fixed by the the developer , I mean hes already taking 2% why should users spend time hacking together fixes for know bugs. |

I think the best thing to do now for someone that want to try mining ether is by leasing a rig (let me explain why). You invest much less to get some mining return, VS having to build a PC and try to find GPU that are NOT OVER valued. Also, when renting, you are not contributing at upping the hasrate, and then the difficulty, because these rig are already mining ethereum when they are not leased.
The biggest rig leasing place is the nicehash, but you cannot lease hashing power there. Is there another one? dont waste your money with cloud mining either mine with your own hardware or stay out think about it why would they lease you hashrate and not make a profit off it ? That in turn eats into your profits from the contract and you end up snake eyes. |

The Claymore new eth miner is about 3-5% faster than the ethminer. Is that also faster than 1.0.6?
I dont know if its verifed that this is for sure 5% faster unless mining pure eth ? also it does not work with stratum and worker name password so keep that in mind |

A dumb feature request:
- set DAG location (like genoil's -R option)Damn I have to read more carefully  Awesome job btw. I was hoping someone will "crack" the original etereum algo and implement it "proper way" even if this happens i dont see what difference it will make since everyone else will use the same algo and mining gains will be the same unless its a private kernel. @Claymore I prefer coinotron for my pool so i really cant test this miner unless i can use it over my proxy with worker name password thanks for working on those changes. |

I don't know why you guys are comparing power when clearly ETH is so profitable that power shouldn't be an issue currently.
You are right, it isn't issue anymore. But if someone suddenly finds a way to cut power costs 30-40% without losing performance on 18 months old platform... Hmm not sure how this statement makes sense. Unless youre a professional miner with a large warehouse you have a hard limit on how many MB/GPU combos you can install. say you were to invest 5k for instance you could buy 33 ($150each) R7 370s that produce 16mhs each for total of 528 mhs drawing 5k or so watts. 15($330 each) 970s that produce 22mhs each for 330 mhs drawing 2k or so watts 15($330 each) r9 390s that produce 28.5 mhs for 427.5 mhs drawing 3600-4000 watts I dont list the 280s and 280x and 7 series since you can only find used ones now. most folks have a finite amount of space and power i.e 200AMP service so if you planed to go big you could fit in far more 970s than the AMD cards since you use far less power. For the normal small miner the 970s seems to be the way to go but if you're a professional miner with lots of space and amperage the 390s seem to be the sweet spot and they are readily available. Normal small miner should go 970 way, power efficient and really good 1080p gaming card. Easy to sell. About that power statement, I can mine ETH with 5 x 970 from 83MH@600W to 110MH@1000W. Thats a really bad hashrate for 5 x 970s and the power use seems low as well. I get 80 mhs with 2 good and 2 crappy 970s ( EVGA scs ) Total power use for the rig is 720 watt what version of ethminer are you using and what OS ? |

Much of the original point I tried to make has evaporated in light of ETH >.015 BTC (.017? .019!?! .02!!!), electric costs should be a non-consideration for most. That said: But that extract fan power consumption is due to the mining as well. So we have to take that in to account.
100% GPU TDP on 970 = 145W Do the math, break it down, here's the numbers: Overclocked, maintaining <70C core temp (high fan profile): gpu1 (incl. fans on card): 108W (75%TDP) gpu2 (incl. fans on card): 115W (80%TDP) 4 case and 2 cpu fans, hdd, mobo/cpu: 50W (case fans ramped to 60%) Total so far: 273WPSU loss: 55W (80% efficiency; 0.2 * 273 = 55W) 273+55 = 328W, or basically what I've monitored on the UPS 42MH/s, 7.8W/MH (total system), 5.3W/MH (gpus only) Stock, maintaining 75C core temps, stock fan profile, both @65%TDP: gpu1: 90Wgpu2: 90Wcase fans+hdd+mobo+cpu: 30W (silent pc mode) Total so far: 210WPSU loss: 42WTotal system: 264W36MH/s, 7.0W/MH (total system), 5.2W/MH (gpus only) Something I'm going to try is disabling Windows Aero. Even though it's a headless system and it's not doing anything, some have mentioned it stealing GPU power all the time regardless of use, therefore decreasing hash. I've seen weirder things, especially on Winblows. God, I've got to roll Mint or something.I've seen the "my 280x will do xxMH on yyyW with zzzV undervolt" before, I still have no clear idea because so many things play a factor in pushing the limit. I've seen people today who own multiple rigs, running mixes of 7950 and 280x, undervolted/clocked/tweaked/whatever, drawing over 3KW to get 350MH/s (9W/MH!), and they're happy with that. To each their own, ETH's at .02 BTC, electric ain't much of a matter no mo. I think I'm done with this particular thread.    Yeah i keep hearing that electrical costs should not be factored in but say the price was to crash down to proper levels at some point those with effecient miners can keep going while others will be out of luck. I expect the price of the AMD R9 hardware to go up anyways as supply drys up 970s will be very competive soon. Right now you cant find any 280x's anywhere, next card to rise is probabl the r7 370s |

What is going on with ETH right now is CLEARLY NUTS!!! Its like 2013 all over again with LTC going from $1 to $50.
Those who mined in Febraury and held must of made a fortune.
I mined a ton like 5k but only held like 500 really mad at myself |
|
|

the hashrate is clearly displayed, you can see 40mega, 40.721.398H, if this is with two 980, it's relly bad, because my single 970 is doing 22M
what version 970 do you get 22mhs with , I have two EVGAs and an MSI and they get 20.9 , 21 and 18 respectively |
|
|
|
You don't have to worry about ASICs coming in and start mining ETH.
You should worry about the GPUs that everybody is buying right now and increasing the hashrate or that price won't crash.
you should worry more about those with cheap electricty, those are the real plague that promote centralization, gpu or asic Yeah mostly the Chinese, at least ethereum is still profitable with high electricity costs right now |
|
|
|
|
Even if your theory was sound eth is only POW for the next 12 months even if we see delays in serenity which is the pow fork you're talking 16 months max , there is no where near enough lead time for anything more than maybe fpa development ASICs are out of the qestion
