The madness continues ...

HWInfo broke my system, had to reinstall the drivers and to apply mods again.
How are we supposed to do any monitoring with these s*** drivers? Any click anywhere outside the console breaks things, random timed out session of Team Viewer breaks things. This is very very f** up.
I really want to see how the hot card is working, but can't really do that with XMR STAK, as everything breaks too easy.

Anyway, I've seen ppl having issues with HBCC. I seem to have one too. Two of the cards are hashing at ~700 & 650. They had HBCC enabled before, now after the driver reinstall I can't even enable the thing.
But even enabled, I still had these 650-700 H/s on these threads, so I don't think it was actually working.
Rest seems to be OK (right now all of that is at 1800/1600). The change from 1600/1600 was a cosmetic +50-100 H/s total, so I see no point in pushing it more.

Can anyone help me solving that issue?
I have 8GB Ram, 64GB Virtual Memory, 6x RX VEGA 64 (Air).
Is 16 GB RAM going to solve this? My HBCC Slider says ~ 11666 MB. Is that the same number for you guys?

I managed to only get 4 cards with HBCC actually working. They sliders show up for the other 2 cards but changing any settings has no effect on the slider and the hashrate reflects HBCC is not working. I even added other AMD cards like an R9 290 and RX 570 later on and it dropped it to only 3 cards with HBCC working

Same with 4 cards only working with HBCC. The other 2 do not listen to their HBCC settings. See https://bitcointalk.org/index.php?topic=2201970 for as much details as I can provide.

The worst is that 2 cards also ignore Soft Power Table settings in the registry. Also a major clue I am sure as to why this is happening.

FYI it seems you need 8GB Virtual Mem per card. My rig only has 8GB of RAM but I tried with 16 and 32 and it did not change anything regarding the HBCC issue on more than 4 GPU.

A major clue recently was that plugging in a dummy hdmi connector to one of the problematic cards while running xmr-stak-amd miner caused the hash rate to spike up for ~10s before it dropped back down.

I have yet to do a clean install of Windows as I would like to confirm why this is happening first so I can save others the trouble. If I clean install Windows and it works then I lost my chance to debug it.

With that said I plan a methodical re-install of Windows to hopefully fix it.

How much MB do you see next to the HBCC slider with your setup? Try changing to more VRam than 64 if u have larger SSD.
I notice, that when I enable the HBCC, the system thinks for a second before closing the AMD Settings, and their fans change speed for a second, so it actually hear that this is being applied. On the other two , the settings just insta close.

Exact same issue regarding how Wattman reacts.

4/6 cards when I modify the HBCC slider at all and hit apply cause the screen to flicker a bit, Wattman closes, you can hear the card "re init" as its fan spins up for a second then comes back to normal.

2/6 cards when I modify HBCC Wattman just closes. Nothing else happens.
