That's a nice HBM clock you have there!
With Stak-XMR set intensity to
1008/904, worksize 4 or 8, strided index
2, mem chunk 8 or 16. Should get you over 1500H/s

https://bitcointalk.org/index.php?topic=3167363.0Weird thing with my Vega is that I have to restart the miner several times until the first hashrate reports are above 1500, then it stays like that...
What are the clocks and voltages?
cannot get more than 1400h/s from my vega64 1408/1150 ((
On the same 1408/1100 soft_pp mod.
With BC drivers, I could get past 1500 H/s but wasn't stable at all used to drop to 1435 and with display turned off it hits to 11xx.
Getting 1460 H/s with Adrenalin 18.3.4 drivers and 1475/1100 clocks @ 881mV.
I have noticed that you need to overclock higher than 1408 on OverdriverNTool with the 1408/1100 mod. I think the driver makes adjustment to the clocks. With default 1408/1100 softmod the actual clocks were 1385 for me.
