I did some tinkering with xmr-stak yesterday as well when I put my two 580s in the Vega rig. I just can not get it to go as fast as Cast whatever I do. Turning the intensity up just makes it crash eventually, and running multiple instances doesn't help like it does with Cast. I have switched to OverdriveNTool for setting the clock settings because Wattman resetting them every crash got very tedious. Interestingly now the 580s are in there, disabling and re-enabling the Vegas after a reboot just blue screens the machine instantly which is quite annoying. I have no choice but to manually do the HBMCC switch in Wattman now. Devcon won't work on my rig anyway so not a massive loss, but still a vexing development. I think a separate 580 rig may be necessary when more Vegas turn up.
Interestingly, I tried running an instance of Cast for each of the four cards and it didn't like that at all - performance of the whole rig dropped significantly. I then thought about how Stak can tie a GPU thread to a CPU thread, and it occurred that I only have a 2 core with HT CPU so four threads max. I then tried both 580s in one instance of Cast and left the Vegas with one each and performance jumped quite a bit, and yet the two 580s remained at the same hash rate - 1666H/s for the two, 827 running separately. I see a drop of about 100-150H/s per Vega with Stak vs Cast, but if Stak had less dev fee that may actually make up the shortfall. I much prefer Stak for configurability and reporting. Its timeout settings are much better for when Nicehash gets socket errors too. Slightly unfortunately, 660W of power dissipation is too much for the airing cupboard The cards are all running at 65°C with the Vega's fans at 3000rpm with is pretty noisy so now the challenge is to find somewhere with better airflow where the noise won't be too disruptive. It would work in the loft, but then I lose all the heat. It can't go in the utility room because that's where the kittehs sleep and I don't want 60dB of white noise damaging their super-sensitive hearing, although they might enjoy the warmth. Hmm...

Baikal Giant X10 is available to buy again and Giant B is available as well but prices are not realistic and MOQ 6, last time X10 was $1399 and no MOQ but now see the reply to my enquiry from Baikal below:

Wow. I guess they saw what their kit was selling for on ebay and decided to take the extra profit for themselves. Slightly ironic that Baikal are now doing moq of 6 whereas Bitmain limited the A3 to 1 per account.
4-5 months ROI at that price so I'm sure they'll still sell plenty of them. |

Way too much risk with the B coming in February and partially killing it off. Shame!

I solved my noisy Vegas
I started off with some fan cowls made from a 4" cardboard tube and duct tape. They dropped the noise level considerably on their own. Then, I used the same tube through a 4" hole in the ceiling to get nice cold air from the loft. Finally, I joined them all together with some flexible aluminium ducting held together with aluminium tape and job's a good 'un. The Vegas are now running at 65° with a fan speed of <2000rpm compared to 3000rpm before, and the ambient noise level in the room has dropped from 60dB to just 38! For reference, that's a from a busy office to quieter than the living room with the TV on. The rx580s keep turning their fans off completely as the temperature in the airing cupboard is barely higher than ambient now. Pretty pleased with that |

Nicely done
I'm trying to do something similar with my Antminers, when I get the time. I've got about 20 meters of acoustic ducting and various fittings and adaptors to hopefully quieten the miners while channelling the heat from my cellar into the house. I was thinking ... if anyone was monitoring my high electricity usage, excessive heat generation and purchases of 'hydroponics' ventilation ducting, they'd probably think I was growing weed

Here is XMR-stak with 0% dev fee if you want to give it a try. Just unzip, copy your config files in the folder and off you go.

Smashed his door in....Could they not just knock. What's the liability on this one as he's not doing anything illegal ???
