Newbie Vega 64 Question

[TerpFan]

Hello Everyone,

Setting up my second rig, this time with AMD Vega 64's. Last night, I installed my first card, started up MSI afterburner,
and then started test mining XMR with the .bat file included with Cast XMR. 1780-1800 h right out of the box with no parameters set, other than fan curve in MSI.

Then I set it to mine some Graft Coin, (same V7 as XMR) with the same 1780-1800 result.


Tonight I come back to add second card, start it up and run it just for the hell of it (before adding the 2nd card). and all I'm getting is 1250 h!

Any ideas? I changed nothing in the bios or Cast XMR. I wanted to run this by someone before continuing. By the way, I'm using the Blockchain Drivers.



Thanks for any help you can give!

Mark

VEGA is glory fabulous VGA, and it quite different settings than other RX cards.

DO IT! Step by step.

Thanks!

I found my answer at Vega.miningguides.com last night. Seems these drivers need to be reset every time you boot-up by disabling, and then enabling each card in Device Manager.
Seems they have script to automate that. It did fix it and I was back to 1800h.

Now, I need to find out why when I installed the second card, the computer wouldn't see it!

Yeah I have devcon.exe enabling and disabling cards every time I run the script (or it reruns itself). Enable and disable cards -> OverdriveNTool.exe to tweak the settings that were also reset -> mine.

change the lane speeds to gen 1 in bios and check if the risers are faulty

Thanks guys!

Followed all your advice, and I now have all 6 Vega 64's running! Now on to the next problem. Fans!
All the fans want to run for a while, then stop momentarily before resuming, all at random moments (not all fans stop/start in unison, but they all do it).
I can't seem to just get them to run continuously like my Nvidia's. I'm guessing it is some software issue.

Also, I now want to work on some power reduction as it's running full bore at 250W per card. Is this what the soft power tables address?

I'm reading and searching like crazy, and there is allot of advice out there.


Thanks again!
