Sobfar I've tried mining both ethereum and no ero and finding better profit in Monero same as most people.
Rig setup is 4x Vega 64 on windows 10
Ethereum best results 38.5mhs @ 1200core/1100mem/power-20%/templimit60 u
Using latest AMD drivers pulling 750W from wall. I find one card is always buggy tho and has to run slower than the other 3 so 1200/1085/-10%power. It's not the card however as I've swapped them around and it's a different card each time I reset the system
Monero beat results are 1850hs dipping to 1650hs after one hour cant get the speeds to remain at the higher speeds.
Using 1200core/1020mem/-5/7%power/ temp to 62
That's using blockchain drivers and 2 threads per GPU.
I've found for ethereum the standard drivers are.much better for the cards and profit margins, blockchain drivers on ethereum result in 1100W+ power draw for an extra 2-3mh per card. And the cards run much harder on the BC drivers.
For monero though blockchain drivers are defo the was to go.
Gonna try zcash out next day or two to see the results
If you feel comfortable doing it, the softpowertable mod that's discussed in this thread will allow you to have more control of voltages on the blockchain driver. Sustained 1900+ hash per card at 130-150 watts on monero is outlined a few pages back. |

Picked up my 4th 64 today (craigslist in my area has some real cheap cards). I guess that finishes off that rig.
How low are y'all pushing core clocks?
All four cards right around 1960 h/s at 150watt/card from the wall.
Red, did you switch over to aeon? That looks to be a fairly good profit.

130w on vega use is feasible if you are down to 900mv it would be about normal. The memory goes all the way to 1100mhz for me on this volt and that seems to be the throttle. I'm interested to hear if anyone got their memory to 1150 or higher but it seems not possible at 900mv at least. I think its capped quite heavily beyond that anyway
I've yet to see anything higher than 1100 on mem on any of the drivers |

Hi, I have a weird problem with my vega64. (only 1 card) I use the Vega64SoftPowerTableEditor to edit MorePowerVega64_142_Modded.reg, Changed some value: P1 to 991 / 810 P2 to 1084 / 820 P3 to 1138 / 830 P4 to 1170 / 840 P5 to 1240 / 860 P6 to 1320 / 880 P7 to 1408 / 910 After all settings, my vega64 can work at 1950+ h/s, but voltage is 0.988v in HwInfo64, not 0.910v.  The core / ram clock is correct. Card: Silver Vega64 air cooler w/ stock BIOS OS: Win10 64bit Drv: AMD blockchain beta (Aug/23) Reboot - did. Reset wattman and set to manual and apply - did. What I lost?  thanks. Make sure your "memory" voltage is set at 910 |

Fan settings are important btw. With my settings the cards only hit ~56C while HBM2 mem is 70+. Manual fan settings required. I use 3100 RPM.
Yeah I am positive I can go a bit lower. I wanted a stable base before I shot for the moon. Next iteration on the rig now that I know these settings are stable I was thinking of 910mv.
I had my mem running at 1100 but for an extra like 10H per card I felt it wasnt necessary given the extra heat. I'll be plotting results and optimizing this once I have more data.
A visual would be nice to see. I'm running at 900mv right now at 1100. Seems stable but if its only a 10 hash difference, I may back my memory off. |

Got back around to messing with softpowerplaytable.
Running 3 64's around 1950ish a card right now. I need to bring down the power a bit. I'm currently at 155w per car at the wall.
How low are y'all running your core voltage? 900? 875?

Spent 5 minutes switching over to xmr today before I had to go in to work for a bit. First attempt and it doesn't appear my mem clock set in .reg edit.
But it was doing 1700 per card at 140 watts at the wall.
Hopefully will have more time to tinker tonight

I found this part to be particularly funny :] "No Thanks Anyone at https://bitcointalk.org who instead of sharing and helping demanded payments. " Hahha ya, saw that. Rednow... |

It's not possible to set the memory voltage, and neither additional tweaks can be tried.
Also, one can't adapt the table to a Vega 56 editor.
Still haven't switched over to xmr yet so I guess I will phrase this as a question. While I haven't played with blockchain drivers in a while I assume its the same as 17.9.x where setting mem volt either in wattman or softtable doesn't change mem voltages but does effectively set a floor for core voltage? This is either a bug in 17.9.x or just how wattman/the card is. I've always moved mem volts in p3 to at/the same as my undervolt (0.9mv) on the core to ensure it sets effectively. |

Here's my settings on a Powercolor Vega 56 flashed with the Vega 64 BIOS, Blockchain Driver, v10 claymore doing ETH/DCR to get 37Mh ETH/2150 Mh DCR: https://imgur.com/a/gHxXSbad settings and speed Thanks for the constructive criticism. Maybe suggestions instead of trolling? You say you "don't want to type that much", yet here you are spouting useless info. Hero member my butt. Lol - cool first post. Why don't yall read the thread. It's over 40 pages. Maybe y'all will learn something. |

DonBit, great work. Can you please find some time and post a step-by-step tutorial of your specific settings? I think I seem to be missing something because I am almost there, but not quite. Thanks!
Check out DonBit's post right before yours. Detailed step by step at Overclocker credits to hellm. |

There's a whole thread on Vega Performance that I'd encourage you to read.
This could be several things. Try switching crossfire to off. That has caused some users issues.

Good mod for 44.1 ETH @ 150watt and 1800 XMR @ 100watt But doesn't work for dual-mining, to low voltage set by driver to be stable my mod is slightly different resulting in stable operations in all mining cases with more speed and more power consumption. Wonder if my cough cough comment earlier helped  I'm switching over to XMR next week and will fiddle around with my .reg. Will let y'all know my results. Powerplaytables have been fun to play with. |

Ok, all we know now that we need blockchain drivers to get good speed with Vegas.
It works only in win10 and only if your motherboard is fresh enough to have UEFI bios. With legacy bios you will get BSOD when installing driver.
The problem with blockchain driver is buggy power management.
And you definitely need downvolt to keep your HBM2 cool and non-throttling.
If you have Vega56 you can follow Hellae instructions (respect!) to get good speed with moderate power (~1300mhz gpu, 920-950mhz hbcc, 0.9-0.92v)
But if you have Vega64 his route I think will not work so you need some special hack.
I do have one that can make your Vega64air or Vega64 Liquid to run at 0.9v with ~1400gpu/1100hbm getting approx 150w from the wall with speed 1990h/s xmr.
It is still 0.4 eth )) I'm greedy )))

Definitely looking nice on xmr. Will switch over in about 10 days and give it a shot.

Web wallet down? Every time I go to check it out, it seems to be down.
Are we down to 2 weeks of mining left? Looks like I'm going to have to find a new coin here soon.

I encourage y'all to watch buildzoid's video on undervolting. There's definitely some wattman nuances to watch out for. If you're brave enough, there is also some fun to be had with the powertable mods. https://www.youtube.com/watch?v=z2rQgQZLyOE |

We have tried to use this case in a server rack style allotment and didn't really stand up to what it needed to do so we went with a custom design. But as to why we disliked it, the case as a whole doesn't seem to like letting cool air in or hot air out. No flow through the chassis on a consistent basis. This may be in part due to the foam in the front cover that folds down. It's better for airflow down but still not as efficient as I would like and also with the foam folded down, dust and another sediment can flow into your chassis with open cases. In addition, the crossbars will limit your use of GPU's to an extent but that won't be too much of an issue for many people.
That's interesting. I recently switch to a Rosewill server case and after all my modifications were said and done, I actually saw temperatures drop compared to my homemade open air frame. I did take the foam front off. I reversed all the fans and am using blower style cards. Air comes in the back and out the front. It's been working really well for me. I like these custom 2nd psu mounts. I may have to try that. I have one PSU in the case and one that just sits on top - outside of the case. |

Mining ETH, LBC, Sigt
Almost done with ETH... Going to have to decide about XMR or just smaller coins

Looks interesting. Will definitely being keeping an eye on this
