a 300w (max) gpu is a perfect fit for a 3 gpu rig config..like a 900w for 3x card plus system power consumption......a perfect fit for a 1200w psu (1200w is a sweet spot for power-price-density-power efficiency ratio)
Exactly! Three cards, one motherboard, one psu, no crappy risers. Powerful and fail proof setup. i use risers, boards that can handle those 3 to 4 gpus are too expensive or rare etc.. 3 risers will be a lot easier to troubleshoot than finding the bad riser in a 8 card riser rig..shuffling by trial and error, testing your spares phew! haha no the 8 slot boards using 4 cards never break and just run with the four cards doing 200 watts each the whole setup pulls 900 watts against the cheap good deal priced corsair 1500 watts atx psu. My up time has been 99% since sept 2017 with zero psu or gpu or board fails. |

Hey how profitable is GRIN atm? for example 1 vega 56 before electric?

Generally those gamer type motherboards which allow triple SLI ( or triple crossfire) are very expensive and you need a huge tower case if you want it to be enclosed.
Reason why is because the last GPU will need to go in the last slot and that is usually where the PSU sits (newer cases have PSUs sitting at the bottom not top like the 90s)
Its basically cheaper to just buy a regular motherboard, use risers and just buy a server chassis and you can easily run 5 or 6 GPUs without issue.

They are barely profitable before electricity. Had one of my rigs with 3 vegas mining for a few days but they had a lousy hash rate in comparison to the nvidia cards. My 3 vegas did around 9 gps total consuming around 530 at the wall. Not sure if they will get improved upon later on with better mining programs, or if amd cards just suck at that algorithm. |

server chassis or any case...nope, just zip tie those cards in the rack and you have all the space you want to be able to put your two hands where you need it when troubleshooting or maintaining. |

i dunno. i had gpus on risers zip tied in the air and found it more of a pita then i thought it would be. maybe it was just me as i was slowly rotating out my 380/390s and replaced them with whatever as i went at that time, and zip ties and risers sure made that The Suck in my book. once the 8 slot onda d8p came out i bought one from phil and never looked back. no risers, nothing loose, easy gpu changes, take the whole rig outside as a unit to blow dust out etc. super neat and absolutely no problems since i set it up. no risers=less to go wrong imo. |

I hate those damn risers. I just threw away 4 of'em. The GPUs started failing or throwing up error 43's in the device manager. In the end it was a combo of bad board and bad risers.
At least now, if I get this type of errors I know to isolate the gpu, and change the riser as a first instance.

We have been mining Beam on Sparkpool and overall it's been a positive experience. They have translated allot of the site now, so you don't have to rely on Google Translate like it was at first (that was a very "interesting" experience).
@ElderIII, Can you mine to a BEAM exchange wallet (ex: BitForex) on Sparkpool? What mining software have you found to be the best for BEAM? Thx |

I've had issues also with the USB Risers. They were also very difficult to diagnose which riser is good or which is bad without actually using it for a while.
This is why some of my open air rigs still used the Ribbon risers from the Litecoin days. You could visually inspect them for fault and as long as it was 16x - 1x riser it was pretty flexable and you could put them almost anywhere.
However you couldn't use all ribbon risers on a 6 GPU rig, basically the first and last GPU on the rack wouldn't have enough length and you had to use the USB risers for those.

"using it for a while" you say?.....that's why my next plan is build a mining rig composed of old gpus 280x or maybe 290s--->like a testing rig. that will be 100% sure that its running PSU, motherboard/cpu/ram/hdd and risers(including usb cable) are problem free, i will put any suspicious riser,gpu,psu etc.. to work there, see if something shakes off. |

Guys how much are you doing with a Vega64 on Grin?
I'm about 0,42 gps on Grin-31 / Vega64 at about 200W.

That's pretty much where you should be, upper end even. What miner are you using? I suppose it's the Minerbabe distro... I've been using it too and it was pretty stable. The only problem is that its web management platform is grossly unpolished and lacks a lot of features. |

@ElderIII, Can you mine to a BEAM exchange wallet (ex: BitForex) on Sparkpool? What mining software have you found to be the best for BEAM? Thx Gminer is the best for Nvidia, lolminer is the best for AMD in my experience. I think you can mine straight to an exchange, but you would still have to manually withdraw from the exchange once per day. Unless they added a new exchange in the last couple of days I wouldn't trust any of them to hold my coins. I would rather use the Beam wallet personally. |

I am not too technical on the details but what is the deal exactly with ProgPOW? It seems that it will level the field with ASICs and GPUs however the brand of GPU seems to play a factor.
It seems that Nvidia performs much better than AMD, and is the reason for this that Nvidia generally costs more and since it costs more they want to make it more fair in that regards.
For example, say you can buy 2 AMDs for the price of 1 Nvidia. The 1 Nvidia will perform at the exact same speed as the 2 AMDs combined. Is this the point they are going for or is it just the way that the current miners are optimized?

good question. this is me below http://solo-bci.altpool.pro/workers/iG5mxRMZErtXwReBaEvpYam7PQStwgK5hRI mostly use 1080ti |

AMD GPUs consume a lot more power for the same hashrate on compute heavy algos. I am not too technical on the details but what is the deal exactly with ProgPOW? It seems that it will level the field with ASICs and GPUs however the brand of GPU seems to play a factor.

I cannot believe that you are still mining this BCI shit. I know you are mining Grin as well, but ffs brother, if you want more BCI, then buy some. BCI is nowhere to be found on mining profitability lists. # I am not too technical on the details but what is the deal exactly with ProgPOW? It seems that it will level the field with ASICs and GPUs however the brand of GPU seems to play a factor.

It is what the current miners are optimized in. One year ago, AMD was ahead of NVDIA on the GPU race. Now things have shifted a bit towards NVDIA favor. Their difference in performance is roughly 1/3 regardless of the coin. New AMD 16 GB is out. |

No, mining currently has no effect on video card prices. That was like 6-18 months ago. Their prices today has more to do with gaming. With that said Nvidia cards do beat out AMD when it comes to algorithms like progpow and mimblewimble. I think the only algorithms where AMD flat out beats NVIDIA are all the cryptonight variants. Anyways its very cheap now if you want to get into mining, but of course, thats because there's no money to be made. The used market is flooded with people selling their mining equipment. And if you buy new you could probably get some good deals. With that said, spend at your own risk. Crypto doesn't look like it will be going up anytime soon. I'm still here since mining heats up the house pretty nicely during the winter. But once it hits April or May I will have to downsize the farm quite a bit. |
