Miner settings are standart - 2 threads with 2016 and 1800 intensity.

Vega 56 crashes with 1800 on the second thread. That might explain the hash difference.

Currently doing 1850 H/s with 2016+1600 threads.

I tried 1850 intensity for the second thread, got 2000+ hashrate but soon crashed.
2016+1800 seems stable so far

Is it worth investing in Vega for mining purposes, or should one just stick with AMD RX 580 series.

It depends how much you believe in Monero.
Best card to mine XMR seems to be Vega 56, with 1850 H/s @ 150W for only 399$ (good luck on that price).

Assuming 399 and ignoring power bill, at current monero price each Vega 56 reaches its ROI in 4 months.

A Vega64 (499$) with rednoW's secret improvements, reaches ROI in 5 months, and each next month does $8.41 over Vega 56.
After those 5 months, it will take 11 months (100$ / 8.41$) to have Vega 64 netting more income than the Vega 56.

Now... will XMR continue to rise or fall? Some point it as the coin that BTC always wanted to be, and in the Deep Web XMR seems to be more used than BTC.

Ignoring the future of XMR, Vega 56 + XMR is today one of the best GPU/Coin pairs, if not the best, to reach ROI.

I'm new on mining, so feel free to correct me if I'm making no sense somewhere.

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 )))

so i need 32gb of ram for enable HBCC on a rig with six vega 64 gpus?

With the fan spun up it seems to no longer throttle, minspeed 2800RPM, temp @ 67.
A clean install of blockchain drivers made the hbcc slider to pop up.
So card does now ~ 1950 with blockchain drivers.

I need 16gb of ram to get 1950 hash with 56 or not? What power use for one 56 with your settings?

I have 2 PCs with both 2x MSI RX vega 64 8GB both cannot use the blockchain driver, it shows grey artifactes on the whole screen on both PC, a few secunds after claymore miner starts. With only 1 card running there is no problem. Anyone have a fix for this?

Same issue for me. I have 2 Vega 56s with stock BIOS.

1 card works fine with blockchain driver and I get 38 Mhash at 920 mclock. When I use 2 cards 2 I get artifacts on the screen and the system crashes. Also do see that my 2nd cards GPUtach turns green instead of read.

I have three Vega cards at the moment. Two Vega cards work well, as soon as I add the third one, there are gray artifacts after the miner has started and the PC crashes. I am yet to test the non-blockchain driver, though.

You mean the GPU tach turns blue? There is a switch on the back of the card, you can choose between red and blue LEDs. The Vega 64 and 56 cards are identical so I use the LED color to mark them -- e.g. Vega 64 = red LEDs, Vega 56 = blue LEDs.

Very convenient.

Disable the crossfire after adding a new card.

Mine seems to throttle back to 1600H/s. I wonder if tinkering with the fanspeed helps. It stays under 67C.

Its because your HBM temp is going over 70c. Did you get your result on blockchain driver too?

Wonder how did you turn it off without a slider ...

I can also do that, and I can't adjust the HBCC size since I don't have a slider, I had but it disappeared after a driver install. I also have 16Gb of RAM.
Here's 56 with 2 threads, it is looking quite good for xmr.

HBCC disappeared when I upgraded to the latest AMD driver also. I think it will be back some time ? It can help in games also slightly, surprised it helps mining.

I'm currently mining ETH but can anyone give me an idea of the correct command line for xmr-stak-amd.exe
I got 30MH or so with 130w showing gpu-z which I thought was ok, it runs cool too. I think XMR is better suited for mining though

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

These are some interesting tricks for mining XMR with Vega that you guys have been posting the last couple of days. If the Vega 56 ever comes back in stock at it's original price it would be a fairly attractive option for XMR, with a pretty decent RoI at current prices.

yes it looks like you can make roi mining xmr with the vegas.

Thanks for the XMR tips, I got 5xRX Vega on a rig
I'll test XMR mining at the end of the week when I get more time to tweak cards

Double Vega power. Each running 900mV gpu voltage.
Seems that with higher hashrate consumption is also higher - 150W per card.
