Anybody having issues with monitoring the health of their rig ?
I an experiencing continuous lock-ups in cast-xmr (and stak for that matters) when I'm running hwinfo64 or gpu-z to monitor the health of the rig.
It's imperative to know temperatures on the hbm and monitor fan speeds.
4 GPU + single PSU is OK. On 8GPU + 2PSU the lockups are frequent (every hour - two).
Any other options ?
I built a console app to get GPU temperature and fan speed, give it a try  https://bitcointalk.org/index.php?topic=2367313.msg24135706#msg24135706 |

is XMR-stak 2.0 as fast as XMR-stak-amd?

my hashrate is 3.7k, feature request:
add each worker's 1 hour avg hashrate to web api.
show my last 24 hours earned coins on dashboard.
shoe estimated daily/weekly/monthly rewards on dashboard.

I need a command line tool to get vega GPU temp and fan speed on windows, is there anyone?

Hello!
I need a help with power table.
I set 850 mV for P0-P7 and 850 mV for P3 HBM memory.
But in GPU-Z Sensors - VDDC 1 V or more.
Why?
Because lowering voltages past a certain point in the power play table doesn't actually do anything. Use OverdriveNTool to apply the voltages. Also remember that memory voltage is actually core voltage floor, so make sure it's equal to or lower than your desired core voltage. Mythic, do you mean we can change clock and voltage using OverdriveNTool, registry mod power play table is unnecessary? |

very very interesting mobo, bit worried about the space left in each gpu (how to cool them enough? it's tighter than a topmodel's bra!) also where did you find that @$#@# devcon.exe i downloaded from small diy files to the entire visual studio and still nothing...
I get devcon.exe from https://docs.microsoft.com/en-us/windows-hardware/drivers/devtest/devconI've installed visual studio 2017 days ago to build xmr-stak-amd, not Sure if visual studio is required for devcon.exe. |

Guys, I'm still dropping to 1500 per card (two vega 64s with 16GB RAM) after 20-24 hours. Am forced to restart everything to get back to 1900 per card. Can anyone share their insights as to what I might be missing? I have the cards running on a rig I remote into, so no displays attached at all (not even to the onboard video). Maybe I need dummy HDMI dongles? Thanks for any help.
I had the same issue with hashrate going to 1700 and had to restart the miner. I noticed that was happening while i was running anything else than the miner that had to do with the gpu ( HWinfo, afterburner). What i did was to lower a bit the oc settings and i was just fine.. I have similer issue, 2 vega56 with stock bios and identical settings(use registry mod, 1350core@850mv, 935mem@850mv), the first card which is pluged into main PCIEx16 slot keeps 1850H/s, but the second card begins at 1850H/s and drops to 1600H/s after a few minutes run. it isn't due to hige temp, both of the 2 cards are under 53C. Windows 10 fall update, blockchine driver, xmr-stak-amd. |

XMR is more profitable than Aeon via whattomine.
XMR 3700h/s 5.47$/day
Aeon 7400h/s(as you say, Aeon hashrate doubles XMR) 4.25$/day.

I hadn't originally planned on putting this out there, but some other asshole decided to charge a fee for this info. Fuck that guy. Here's how you run 4+ Vega at full speed while mining XMR. Basic Users: 1. Use the Blockchain drivers. 2. Open up your device manager. 3. Open up the "Display Adapters" dropdown. 4. Right click on one of your Vega's. 5. Disable that fucker. 6. Wait a few seconds. 7. Right click on the Vega you just disabled. 8. Re-enable that fucker. 9. Repeat steps 4-8 for the rest of your cards. 10. Enjoy mining at full speed with as many Vega as you damn well please. Probably. Advanced Users: The previously described process is a bit of a pain in the ass. Let's automate it. 1. Get your hands on the Windows Device Console (Devcon.exe). This will let you disable/enable devices from console. 2. Run the command devcon.exe FindAll * to generate a list of all the currently attached devices and their hardware IDs. 3. Search your newly generated list for "Radeon RX Vega." You should find something like this: PCI\VEN_1002&DEV_687F&SUBSYS_0B361002&REV_C3\6&3AAC35E3&0&000000E7 : Radeon RX Vega 4. The part to the left of the colon is what you need. Shocking, I know. Put that thing into a batch file that looks something like this: @echo on
cd C:\Users\Mythic\Desktop\Startup
timeout /t 5
devcon.exe disable PCI\VEN_1002&DEV_687F&SUBSYS_0B361002&REV_C3\6&3AAC35E3&0&000000E7
timeout /t 15
devcon.exe enable PCI\VEN_1002&DEV_687F&SUBSYS_0B361002&REV_C3\6&3AAC35E3&0&000000E7
timeout /t 15
OverdriveNTool.exe -p0Vega0 -p1Vega1 -p2Vega2 -p3Vega3 -p4Vega4 -p5Vega5 -p6Vega6
timeout /t 10
cd C:\Users\Mythic\Desktop\xmr-stak-amd
xmr-stak-amd.exe
5. Run your batch file at startup as an administrator. Enjoy never having to toggle the HBCC switch again. FAQ: Q: So, Mythic, how exactly does this enable HBCC on cards 5-7? A: It doesn't! HBCC Does nothing to improve your hashrate! Turns out the drivers are just shit and are bugged when Windows first boots up. Who would have guessed? Q: But Mythic, does that mean I don't need 16 GB of ram to run my cards at full speed? A: Correct! 4 GB of ram is completely sufficient! Q: If I wanted to donate some pizza money to the broke ass college student that typed this up, how would I do so? A: You ask the best questions! I doubt I'll get anything before more well known people/websites copy everything I just said (with no credit, obviously), but here are some addresses just in case. XMR: 42e8AWjcirkBDzCNnSjPxeGJeht71kFfWcoxxCWsxe8HZqP29NruDsxcvVSjbKw17AUDepopK7ZYCUn mRvcGS9kBT5XWhMQ ETH: 0x74Ed2CA095Dd3aE98D88d5ca1dDb77E752152938 Thank's it's working great. So it's more a bug in the driver with the HBCC option. With this in my batch, i don't need anymore to disable/enable HBCC on each card, i have full XMR hashing speed (1900 by card / 4 VEGA 56@64BIOS) what's your power play table settings , fan speed and GPU temp? |

50k$ means about 20 rigs, it isn't a trivial work to manage so many rigs.

I follew the definitive guide in reddit, vega56 with stock bios get 1850h/s @～190w, 3000rpm fan. with vega64 bios cannot work stable. Some questions:
1. how to check power consumption with software? nvidia-smi shows clearly for nvidia cards, if there is an AMD equivalent?
2.1800h/s is fine, but the fan @3000 rpm is too noisy to me, how to make the card cool enough with lower fan speed, maybe undervolt?
That's good. You can check it in GPU-Z or HWinfo64, but you have to sum up VRM and chip wattage. It still won't be probably 100% accurate. I don't have VEGA so I don't know what it shows. Sure undervolting will give you lower temps also you can add additional fans. Thanks, I've figured out how to undervote it. specs: 8G ram, 40G virtual memory 2xVega56 with stock BIOS Windows10 fall creator update x64 auguest 23 blockchain AMD driver use power play table in registry, core clock 1350@880mv, mem clock 935@880mv fan 2200rpm XMR-stak-amd, intensity 2016/1600 The rig has run 8 hours, very stable, it uses 360 watts from killawatt, card temp is 53C, 3700h/s. |

We are talking about speed 1900-2000h/s and power usage like 130-150watt. awesome, use 64bios or stock 56bios? how to reach 2000h/s? |

looks awesome, I'm a noob on amd cards, I haven't figured
out how to burn bios, overclock, edit regedit, etc. Will try it once everyting is ready.

I have 2 vega56, does vega64 bios increase hashrate?
|

Since you have already a vega56, you know the hashrate and power consumption, calculate ROI in http://whattomine.com |
