What about if you don't use HBCC? HBCC it using system memory, so if there is any issue with your system memory, faulty, unstable frequency/timings, lacking voltage etc, then that could cause various issues in itself. Keep things simple when troubleshooting a possible faulty GPU.

Yeah it crashes the same without HBCC
Btw I finally got this with a program even tho I dont get any bsod:

also tried to increase "TrdDelay" but it crashes the same didnt fixed it
Also I got this file:
atikmdag_dce.log in C:/AMD

Hi, Do you run your PC with HBCC on by default?
I ask because I've not used it at all and I'm wondering if I should turn it on,
I have 2x 8gb sticks of 3200mhz ddr4 memory with the Win 10 Pro OS and when I turn HBCC on it has a slider that is all the way to the left showing 11786mb which I presume is the minimum amount of memory I can allocate to HBCC.

Fun with Vega(s)
(EDIT0: having fun figuring out how to actually post images...)
(EDIT1: Okay, I guess I'll just post links since every image I try to link to is broken)

Max draw was about 950W from the wall (just sipping that power!). That aside, looking at the 1x card leaderboard, that puts me under a Titan V air-cooled, in the vicinity of a 1080ti on LN2, slightly above a Titan X/Xp, and 15% above the nearest 1080ti air-cooled card, so... not awful for a 2x 64 Air setup...?

When running a single GPU i test performance in game X with it on or off. If there is a perf benefit and i need extra performance, i enable it, otherwise i keep it off.

However at the moment I'm using 2x Vegas in CrossFire in ROTTR so HBCC is disabled by default.

Yeah it crashes the same without HBCC

I would prepare yourself for the worst, that you have a faulty GPU.

It is, They've also reduced the usual 3 year warranty down to 2 years for Vega,
If they can't be arsed AMD should cut them loose so they can stick to Nvidia which is where their focus is. Half arsed products damage AMD's reputation and seeing as there's this apparent lack of chips they'd of been better off giving them to Sapphire or Powercolor.

Powercolor's Vega reference warranty was stripped to 1 year. (not kidding)

XFX is 2 years. 3 years on their custom cards which... Only the GTR series... which hasn't been released yet for RX Vega. Its still 2 years on their current "custom" cards. Which btw- RX Vega56 is $800 at Best Buy right now. lol

Gigabyte still retains its 3 year USA warranty on Vega reference cards and their custom cards.


I tried HBCC earlier and it worked fine for me on Prey and WiC.

I would assume there is a fault on the card or maybe... Nasha... Try updating the chipset drivers? (your motherboard drivers) I've seen in RARE instances where chipsets have issues with some GPUs.

Sounds sensible, Cheers.

I'm surprised they only offered one year, I have a Sapphire that only has a 2 year warranty which is bad enough, It's about time they all improved it like Gigabyte and Zotac who offer 4 & 5 years warranties on the Nvidia side of things.

Hey man I got some news, not bad not good either.
I did gaming session of CoD ww2 while recording and look what it didn't crashes, but with HBM memory locked at 800 mhz , any hintsigh?

And it crashes at 945Mhz?

I will play some COD WW2 and test it on my known stable system.

Tell me what i need to enable in terms of HBCC and or Relive.

And Sapphire is 2 years for reference liquid. I know that because I think mine is broken

VRAM has many errors with random blocks on MemtestCL. Occasionally my OS crashes without blue screen, just turns black yet the computer stays on (no the monitors aren't just turning off). Very weird. I'm hoping it's the GPU causing this and a warranty fulfillment will correct that.

 

[LtMatt]

I just ran thart MemtestCL and got thousands of errors at stock so not sure how valid those results are.

I always personally keep HBCC on for everything even if there's slight perf degradation because I really appreciate the extra (system)V-Ram. I'm playing Injustice 2 ATM which is using about 8300 MB a lot of times on 34x14 ultra w/ 64x Tesselation and Enhance the application w/ Supersampling forced via Radeon Settings (honestly don't see any huge difference, so not even sure whether Radeon Settings is successfully forcing it).

Not yet come across a game where I feel HBCC isn't really helping. So many games w/ texture resolution settings and other stuff can easily be taken post 8GB Vram (atleast on 34x14).

I haven't tried using HBCC yet, I haven't felt the need so unless it helps performance in certain games I'll leave it off for now, That said I'd like to make a list of games where it improves performance if you can think of any please let us know. Overall my Vega 64's proving to be a great card at 34x14, It's doing better than my 1080 did, some of that may be due to Freesync but even so I'm seeing more consistent performance where as with the 1080 some titles got a bit messy so that I'd be able to feel it in game and turning on a frame counter would show fps dips, Thankfully I'm not seeing that with Vega.

I get your point, my only contention would be, why not use it? We're all playing mostly on Ultrawide locked at 75-100hz, so it's not like you're gonna notice a 50 fps difference at 700fps.

Just keep it on, configure it to the lowest, that would be about 11.7GB total VRAM and forget about it. Play your games and enjoy the extra 4GB Vram.

You're less likely to come across a game which will give you 'serious perf degradation' using HBCC. A frame or four here and there in a game or two, who cares as long as it gives me the benefit of loading up more and more stuff.

Maybe but I've read about some games running slower with it on rather than off, In fact I think Matt mentioned problems with one game a month or so back but I don't remember which and whether it was fixed or best turned off in that game. My performance tends to sit at 60 or more in the majority of games I've been playing which is inside the 30 - 75hz Freesync range of my monitor, I'm not a twitch multiplayer so I don't need higher framerates than that 99% of the time. I'm happy with the performance I was just interested in knowing which games HBCC affects negatively when it's on and which get good improvements. There's no need it was just out of interest.

Again, that's exactly what I presumed you'd be doing as well, the only real problems I've heard people having with HBCC is when they're using mGPU setups.

I'd advise you to just leave it on and enjoy a crucial Vega feature, and btw, I remember seeing some very recent Computerbase.de (?) or some site testing GPU's in 2018 where they exclusively tested HBCC, and from what I remember, it had the biggest advantage in 1080p. 1440p and 4k were near identical if not a +0.5-1.5 fps gain, so don't miss out on it because of some early drivers/reviews and performance gains/losses you're not gonna feel anyway.

I say this because I presume you're a max everything play at moderate frames ultra settings (or increase texture resolutions to match your preferred fps, for me its 45-50), and you would really see a GREAT benefit there.

For e.g I've been recently playing R6 Seige (w/ 70% Render Res ,where 50% being native) and Injustice 2, Wolfenstein 2 w/ 6k textures all of them utilizing 8-10GB Vram and I've not felt any performance loss whatsoever. It's a feeling you don't want to miss out because of some near-inconsequential things. I'll edit my post with the article once I find it.

Edit - Here are some recent articles

GN - "
In the interim, there’s really not much reason to disable HBCC, and it occasionally provides a 0.5-4.0% performance increase. Limited system memory would be a reason, of course. It might be worthwhile to enable HBCC and just leave it in the background, hoping occasional uplift will emerge. We can only speak for the applications which we’ve tested, naturally, and there’s potential for HBCC uplift in production applications (untested) or memory hog games (user mods for Skyrim and FO4, for instance, are often VRAM pigs). In the event you encounter one such game, HBCC enablement could help; of course, if stability or system RAM issues are encountered, there’s obviously not much loss to disabling HBCC, either." from here


Here's another from PCGH.de

" All the bigger was our surprise, as it was here that the Radeon RX Vega 64 was able to gain a staggering 11% and 14% respectively - depending on the driver used.
In the other tests, the result was more mixed, but apart from a single 3% drop in min-fps we were able to measure a (very) low performance advantage through the bank. This may, depending on the game, logically different behavior - problems occurred in the test as I said but not on. AMD will continue to drive the driver in the future and even if it should be our prime example to an outlier, it is likely that one or the other percent of gaming performance by better understanding of the possibilities offered by the HBCC and corresponding optimizations are quite in it.

In the meantime, the hot tip for all Vega owners is: Activate HBCC in the RSCE Control Center, click Apply and restart the computer once for safety" SOURCE

Hi to add to the xfire findings, I found that undervolting /downclocking was the way to go. Yeah so trying 1.250volts 1772/1100 50PL was instant crash. Couldn’t get a reading from hwinfo as it crashed!

So I’m now running 1.160 volts 1702/1080 50PL. It is running nice. Hwinfo gives 300W per card and CPU is showing 150W gaming (although IBT pushes that up to 200W).
Even so that would be 800W CPU & GPU fully loaded.
I have M2 sammy 960 Evo, 2 x 500gb SSD, 1Tb SSD, 1gb HDD, 2gb HDD. Not sure what that all uses, but should be less than 150W.

I’ll be sticking with this, Ryzen & Vega are both flying!

According to Gamers Nexus, when they tested it, it made bugger all difference to the Vega cards you can actually buy, as they have enough vram, and that when AMD were showing it off before their release, and you saw the big gains in Deus Ex Mankind, ROTR with it on, they were run on a 4GB Vega card that doesn't exist (3:44 on in the Video below), where id assume, the HBCC would make a difference on a card with that low amount of vram, as it just isn't enough.

And it crashes at 945Mhz?

I will play some COD WW2 and test it on my known stable system.

Tell me what i need to enable in terms of HBCC and or Relive.

So far some gaming yesterday and up until now it didn't crashed until now, I'd say quite better because before it used to crash under 10 mins but locked at 800 mhz I played 1 whole hour withouth crashes so 0 crashes yesterday nor today until some mins ago with a purple screen; yes at 945 locked it crashes. As weird as it is I thought of go in and leave cod local game recording with bots without touching the pc( only start the games) to see if it doesn't crash

About settings I used for HBCC default 11g+ and relive default settings and amd built-in osd with default metrics too (tried moved them to other sides and stuff and doesnt matter it crashes the same).

I forgot to enable HBCC, but i complete the first mission and recorded the whole lot on Relive with the Overlay running and i had HBM overclocked to 1060Mhz. No crashes on 18.1.1.
