Ive been unsuccessful running more than 4 cards per rig.

My solution was to buy more motherboards and run 4 cards per rig. This has increased my cost, but there hasn't been anything yet i've tried that has worked.

I've had as many as 8 in a rig working fine, but HBCC enabled only on 4 of them, and i've tried this across multiple motherboards, different things.

I have one potential solution i will try when i get time to take a few rigs offline for a few hours. We'll see...

do you try the new driver 17.10.2? probl. the problem is gone?

I have just tried this with the same outcome, 4/6 cards will enable. What I have noticed is that 2/4 of the cards display as "unknown" under the PCI Bus in System whereas 4/6 show as PCI-E v3.0. So the cards/driver cannot read the PCI bus properly?

Have you tried using some ridiculous amount of VM like 256GB, or say 128GB or real memory ?
Would be interesting to know if it makes a difference.

check the web stats of the xmr stak using another device on your network, not the rig itself, so you can read the values real time without touching the console to see whats up. I have not done taht yet, as I need to have physical access to the router.

we have a bit different settings for sure, but its all odd ... I have modded 5 cards - 1220/1100. The sixt is manually adjusted with wattman to 1220/1030 , but its showing even better results, drawing probably more power, but it is what it is.
Also, I am at 1800/1600 intensity, as the thing was crashing after a while on 2016/1600, so I moved it a bit under, and its stable for around a week like this.

Yeah no luck fixing this so far. Has nothing to do with Virtual mem or ram at this point. 8GB of ram to enable HBCC. 8GB of Virtual mem per card to run xmr-stak-amd with the intensity settings to hit 1900H.

Now something weird I've noticed.

Roughly every 24 hours of mining the two cards that refuse to enable HBCC and hash at 1300H suddenly hash at 1900H for ~10min then drop back down.

I am going to try to enable to web client for xmr-stak-amd and write a scraper to monitor the hashrate more closely than I can by randomly checking up on it. Also appears you can have it write the hashrate out to a file, that might be easiest.

I've seen that too, as randomly my max hashrate is 11500 instead of the usual 10000 that I am on. But no idea if that was for a second, minute or more.
The worse thing about this shit is that you cannot combine 4 vegas with other AMD cards, as it still does not work afterwards on all 4. So either 4 vega or you should add nvidia cards, but that does not really sound like a realistic option, as currently nvidia cards are too overpriced.

Or maybe , the whole thing is a visual glitch, and the 5 cards where I see a HBCC slider enabled, are indeed hashing at around 1900 ea. As how can you explain this? http://prntscr.com/gwokm2
I've had such values , over the 10000-10020 that I see on the console the whole time since my last restart 5 days ago. And on top of that I have only 96% good results .

Same with 96% good result.

Your screenshot basically mirrors my exact avg hash rates on nanopool, ~10500. My reported is almost always 10200 but on nanopool it always averages 10500 or higher.

I imagine we both have the same setup using the soft power table mod.

The only correlation I can find for the random gain of +1200H once a day is it appears to time with

Just to be clear with 6xVEGA 64.

4@1900H + 2@1300H (due to HBCC not enabling), total of 10200H. Randomly every day it jumps to 11500H for a short period. The only correlation I can find in the system logs is Windows Defender Updates.

Very strange.

Ok 8 Vega 56 and even tho it says hbcc is working on 6 it's not. Tested 3 and hashes at 1840 per with 8 they hover around 1350 for all. This is more than likely a combo of amd drivers and perhaps pcie bios settings or lane limitation. Someone more creative than us hopefully figures it out and shares.

Good thing when I ordered parts for my new rig I grabbed a 500 GB SSD which I never do. Thanks to all in this thread you may have saved me a headache.

anyone know if it's possible with 1 rig to have some amd (vega) gpus mining xmr and also have nvidia gpus mining equihash? thinking of going this route as a bandaid for this HBCC problem

I'm just getting into the vega+cryptonight scene.. So is this issue about only 4 out of 6 vega gpus having low hashrate specific to a few users or ALL windows users currently?

The issue is 2/6 cards are hashing monero as if HBCC is disabled (so ~1300H).

4/6 cards are hashing proper (~1900H).

At the moment I am just not mining monero with the 2 that hash low due to HBCC not enabling.

This issue appears widespread. Other forums have other people complaining about the same.

The best I've had is 5/6 working but only after a full clean install, first reboot after the clean install and I am back to 4/6.

I should probably move to AMD forums and start asking them for help. The right people might see it and fix it officially. I am positive it is a driver issue and can be addressed.

I was thinking about buying some vega 64 or 1080ti how does the vega hash on other algo's

probably all. including me too.

I once had 5/6 hashing at around 1800/card, but I couldn't repeat that ever again.
I'm back on normal driver now on ethash, I got fed up with the buggy BC driver.

BTW I could turn on HBCC for all 6 cards, but only 4 of them had the slider.
