Disconnected the iGPU and used the 30W gained to decrease the power limit to -18% from previous -20% on the 3 Vegas.

Each Vega 56 is now at stable 1850 H/s, for 5610H/s @ 570W total system on the wall.

you mean iGPU in BIOS ?

Yes. I was with ~1800 with -20% PL but had the iGPU active due to other tests, consuming +30W. With it disconnected I decided to keep using those 30W by increasing PL to -18%.

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.

do you guys think these high hashrate can be achieved with 4gb Ram systems ? (in my case , 1 or 2 vega cards)

No. Currently you will even not see HBCC slider if you have 8 or less gb ram.
Don't even know if 12gb is good.
All positive reports are with 16gb ram

well you're right, I have no slider with 4gb.

I was between 1200 and 1300mh/s with my vega 64 and wattman finally installed.
As I don't have the HBCC slider, I tried to turn off the feature per curiosity.
And I'm achieving 1800mh/s with the 2 thread trick, both @ 1900 intensity.
Don't know yet if it will be stable.

I have to think about : is it worthy to buy more ram now ...

I have no slider, I have a box to tick.
It's written "hbcc memory segment" and I can enable or disable.

Can someone give a hint about ETH miner that can run with 2 gpu threads on 1 card and is compatible with Vega?
Claymore 10 cannot do that.

Try to run 2 instances of Claymore miner

I doesn't work (( 0 speed.

HBCC is Vega-specific at driver level, correct?

Yes - it is AMD new technology appeared with Vega Frontier and RX Vega

Guys I don't get it, your screens show one vega running at 1000h/s not 1900h/s.
This is mine at 1585h/s.

It is only 1 Vega at the screen running 2 threads

if anyone has problem with wattman not working, I almost solved it by plugging a HMDI dummy, as suggested few post above.
It didn't like to be blind, wattman seems to want a monitor.

(but it still often crash)

Blimey that's not so bad after all.
Do you need a given amount of ram to get these hashrates, i.e. A minimum of 2x hbm? What if you use several Vega GPUs?

As far as I know 16gb will be ok for RX Vega rig.
For Frontier edition my guess is 32gb ))

Guess Frontier Edition with 16gb can do 2.5 khashes. But one will need 32gb of system RAM ))

2 Hellae

Miner settings are standart - 2 threads with 2016 and 1800 intensity.
HBCC set to 14400 mb, gpu-z can sometimes drop speed so need do reapply HBCC settings to fix it. Or not to use gpu-z ))
Power tuning is private yet, sorry.
