What do you need to know? Everything should be in the README.md file. Debian should be no problem, nor any other
major distro. I didn't mention it because I assumed most Windows users would find Ubuntu less intimidating.
So, here's the tentative plan: 1. set up a new VM with all cores and 4 or 8 GB of RAM 2. install Debian on it, probably a net install of Debian 8 3. run build.sh 4. install whatever coin wallet software and set it up so I can mine to localhost. This is almost what I do with my Windows VM; installed Win 10 on it, downloaded the wallet software, and ran three different versions of cpuminer on it. (I come from the ESPERS thread, there have been 3 versions of cpuminers there I think.) I run Windows Server 2012 R2, so I use Hyper-V on one of my little boxes. I got it cheap, used, something like $600 USD for a dual quad core 48 GB ram rack server. Only stratum has been tested so I have no idea how it will behave if you try anything else. |

Thanks. I'll look into it.
Hey monoxide, when you get the new cpu miner working on a Linux VM, kindly let us know how you ran it, and what distro and stuff. I'm inclined to try it out on Debian (Jessie). If I can bump up my 100 khs to 200 khs that would be fun. I bought my home server because the Xeon chip on it had AES support. I think it's a e5640. What do you need to know? Everything should be in the README.md file. Debian should be no problem, nor any other major distro. I didn't mention it because I assumed most Windows users would find Ubuntu less intimidating. To avoid hijacking this thread you can post questions in my thread, see sig. |

Optimized esper CPU miner released, 56% faster than cpuminer-hmq1725 on
CPUs with AES_NI. See my sig for details.
I recommend using the GPU port at suprnova. The CPU port has a rough start until
the diff settles.
wow 56% faster in mining espers? what would be your average mine now mate if its possible to share and what's your mining rig you got a ggod code over I just don't know or sure if my laptop can handle it. i7-6700K @ 4 GHz, 214 kH/s. Thank you! Would like to test my i7-4790K @ 4.8 GHZ, but don't know how to compile for windows. I'll repeat what posted in the other thread. You can use Virtualbox to create a virtual Linux machine where you can install any Linux distribution you want, Fedora and Ubuntu derivatives are known to work and have all the depenencies in their repositories. If you allocate all CPUs to the virtual machine you can get the same performance as running natively. |

Is there a way to get windows version? You can use Virtualbox to create a virtual Linux machine, same performance if you allocate all CPUs to the VM. |

cpuminer-opt v3.2.4 has added added support for espers with optimizations. It's 56%
faster than cpuminer-hmq1725 on CPUs with AES_NI. See my sig for details.
My i7-6700K @ 4 GH hashes at 214 kh/s.

appreciate your work. Is there a way for a noob to compile scrypt-jane support into your latest optimized cpuminer? Thanks.
cpuminer-opt (see sig) supports scrypt-jane and many other algos. |

is this better than the wolfo version for hodl and esper?
It should be equal to Wolf0 on hodl and esper is not implemented yet. Edit: I'm taking a look at espers and i think I can improve it. |

If you have more than 6 cards,you need powered risers . A 750ti draws 50-60 watt depending on what you mine. So a 16 cards rig will only draw around 1000W. The bios might need to be cracked to support 16 cards, and more than 8 cards in windows is a pain. Have anyone tried 5 7990's in one single rig ? (10 gpu's)
You probobly need linux. Expensive PCIE splitters etc.
powered riser are useless if you have asrock h81 with two molex, i always used ribbon standard risers and they work fine for every card out there, also cost less than powered riser I have to disagree. Although the mobo can supply the power cheap risers sometimes can't. At least with powered risers you're not trying to push 75W through a ribbon wire. It also reduces the overall power going through the mobo. The cost difference is trivial, no more than .05 BTC with risers on all 6 cards. If using two PSUs (not my thing) I believe you need powered risers to isolate them. |

There will be no dual miner. I respect the opensource work of genoil @ co, and I don't have time to rewrite from scratch. But my farm is out of riser cables again, and I will be going private and retire.
cheers.
Not sure what this is about... If he rewrites eth from scratch he can keep his decred private. If he uses genoil's open source eth he has to open his decred source. If he just quits he can keep the tainted dual miner and use it for himself. |

yes, there is no more telnet command in windows 7, so i used what i can  Is that Windows Home? It can be turned on in the control panel of Pro. |

Thanks for the input and suggestions. Well after a ton of trial and error, loading drivers, and updates I think the rig is starting to act somewhat stable and I was able to get the GPU up and running, then added one at a time. Finally have all 6 gpu's connected. Looks like a good portion of the issues stemmed from ASrock drivers issues for this mobo. The included drivers were junk, and the software/online updater fails. So I found the downloads and installed them individually and I think I have everything updated now. Now with the drivers and Windblows updates done it is acting more like it should.
Now the issue that is appearing is that when running CCminer it will run for a while. Sometimes for quite a while and then suddenly it will start screaming:
GPU #X result for nonce $00000000 does not validate on CPU!
Then it will run away and then CCminer will crash. I have restarted this multiple times now and the same behavior keeps coming back. Any input on why this may be happening? Thanks again.
Same GPU? How are your temps? |

Looks like I have to divide my hashrate on those 2 algo's by 1,000.
Which is the pool's fault I think....not sure. It maybe Minercontrol not able to read the high hashrates.. not sure.
I don't use minercontrol but that seems overcomplicated. You don't want to distort the actual hashrate. The scaling
only applies to comparing profitability after normalization. Simply include the scaling factor with your normalization
of the applicable algos. Shouldn't that work?
Correction: Actually zpool is presenting the hashrate in a different scale so yes you must correct it before normalizing unless minercontrol tries to autocorrect. |

i think it's not wise to go with many gpu on a single rig, you need anyway to pay for additional psu, nothing will change for the wattage, and you need to buy splitter that cost a lot, like the other part of another rig, which are cheap anyway
stick at 5 or 6 cards per rig. make a second rig at that point. reasons are simple enough. 1) if one rig fails you are still mining on the other rig. 2) cooling may be easier with two rigs ie use a separate room 3) you can do one rig at each pool 4) cost for the asrock board is under 100 5) cost for windows 7 is under 50 6) cost for some ram is under 40 7) cheap ssd is under 60 8 ) so the net extra is under 250 you get a lot for the 250 9) if a second coin arises besides Eth one rig on eth on rig on new coin Well put. A few comments: 2) limited cable length would increase the card density and heat concentration. 3) hadn't thought of that, a little easier than running 2 instances on one rig. 5) linux is free and has better remote management. 10) No risk rig will overload electric circuit. |

I tend to agree. Once you start needing multiple PSUs and port multipliers it's probably better to build a seperate rig. |

Heres a trickky question:
Is M7M considered a SHa256 algo? >)
What is the context of your question? It is a chained algo that includes sha256 but it's not for the purposes of scaling zpool's profitability estimate. |

Thanks for the replies on this. Everything was on stock settings as I hadn't had a chance to try and tweak anything. So I rebooted the box a couple more times and tried to watch MSI Afterburner to see if I could figure out what was happening. Sure enough when I tried to start ccminer the power, and temp shot to the moon and then crashed the video driver. Not sure why since it was still at the 1060 core speed and 1350 mem speed. So I cranked it down to like 600mhz on the core and turned down the power to 80%. I then started the miner and it would start and run at like 40khs. I slowly put things back to the stock setting in MSI AB. However the speeds did not increase from the card. I noticed on the runs where it was crashing the speed was about 200khs before it crashed.
So now when I try to adjust the speed up in MSI AB it still does not increase the mining speed. So I don't know if I need to unlock these cards or if there is some trick to getting any speed from them. I am still baffled why it would behave this way out of the box and act like it was being super OC'd and crash. Now I can't seem to get it to pick the speed back up.
Thougths? I checked the physical and virtual memory and both are at 16gb so it appears it should have enough swap. Thanks again for the feedback.
Update: I just told MSI AB to reset, then I rebooted, and then tried to start ccminer and it appeared to overload the gpu again and just quit. I did see the has rate increase to 140-160khs just before it hung. So Windblows is updating right now, then I will try a different card to see if the same thing happens.
How many GPUs do you have and what's your power supply model? I think he's trying to get one card working. I think it's a HW problem, GPU or MB, maybe power but unlikely with only one midrange GPU. Maybe a bad PCIe connection, are you using a riser? powered? Maybe a bad slot, try another slot. Swapping GPUs should nail it. intensity problem? Different symptoms AFAIK. Too high intensity usually causes the miner to error out, not the driver to crash. |
