These are crazy power hungry when pushed. Join the discord as others may have some views and experiences to share there in the z11 channel as well... but the trick at that point in your testing would be to see how much power you can pull back out while maintaining a given hashrate. Tuning each board may help you optimize the power draw as well.

Some folk have cheap power and don’t mind the draw, others are undervolting to maintain stock rates with lower power draw.

I, and the quote above were talking about the GPU on board memory.  You could definitely try adding more system memory, but I don't suspect that is the issue.  I think your setup would likely work as-is if you were using Linux, and possibly an older version of Windows.  I also think if you wait a bit and mine something else, the issue will get resolved with a future miner software update.

Seems a bit low on RAM. I would try bumping virtual memory to 40-50GB, disconnecting half of the GPUs, and then re-adding them one at time.

Nvidia 6GB cards and AMD 8GB cards supported. 6GB cards in Windows10 may not work as WIndows steals some of the memory.

Much!

I wouldn't call that a good job just yet.
Admittedly it's probably the best miner for x16/x22i available for AMD thus far but... Think about it, your Vegas are hashing slower than regular 1080's for what... 50% more power?

I've got a 5x1080 rig that hashes at a combined total of 43 Mh/s @ 700W.

No offense meant to andrucrypt & co, I'm not a coder myself. But as long as AMD devs keep using stone age, unoptimised kernels from Wolf0 we're not going to see anything decent.

Oh wait, actually there are decent devs on these boards and they have just smashed it by releasing totally new code for CNv8 and Lyra2z that beats anything that was released so far. Look'em up.
