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

Thanks for info and links, As suggested I'm going to turn it on and see how it goes for a while, If I'm having no issues with the games I play I'll leave it on, Cheers.

Nice one, Thanks. Have you seen the in stock prices today

I'm almost tempted to sell mine.

EDIT: The gaming results are pretty poor with the biggest average framerate difference being only 2 frames and that was 2 frame faster with HBCC turned off in Mankind Divided which is odd as that's the game AMD where using to showcase HBCC leading up to Vega's release. :confused:

Oh well, I'll give it a go.

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.

Same using 18.1.1 as well
I've been testing with cod ww2 since release date and I still discover something new huh
So far I've played the 3 first campaing quest which took about 1 hor 10 mins recording with relive and osd and I didn't had any crash huh, and that was just right after playing some multiplayer and crashed(i never tried the campaign, only MP)

Not gone up again have they :eek:

Yeah the gaming results are poor, funny how on their special 4GB Vega card they made to showcase it off on, they looked great

EDIT: **** ME!!! The Devil 64s are now £1100!!!!! :eek:

That Raj was a duplicitous git imo, I'm glad he's gone.

Shocking innit, At least it makes me feel like I got a good deal on mine

And this is most likely why there isn't a 12nm RX Vega refresh on AMD's road map. Why bother? You can stay on 14nm and sell every chip you make regardless. Might as well keep working on Navi for the next 18 months and that'll be why they are looking at a 7nm Instinct card to test out the node. By the looks of things they might just jump from 14nm straight to 7nm and be done with it. I also think AMD, board partners and re-sellers are all now hooked on the crypto drug and are struggling to get off it. Those high prices are certainly addictive!

The potential real loser here is Nvidia because if the prices stay this high how are they going to sell the 1170/1180? I would imagine most current Pascal owners will wait until the prices normalise again, if they ever do. TBH it could be a real mess for everyone as you can pick up an XBone X for £400 and play games at 4K or pay 3 x that to play at 4K on a PC. Doh..

My RX Vega 64 air now seems a real bargain at £449!!

Jeeze... They really gouge ya'll over in Manchester, UK.

Thats like..$637.42 USD

I paid less than that for my Liquid card here in the USA. (but you already know that.. haha)

I've already made my decision to hold off on getting a new CPU/Mobo/RAM platform till RAM prices drop at least 25%. This FX-8320 I have is still holding its own for all my gaming needs. Can't upgrade to the platform I want with memory prices where they are since the platform I want, uses quad channel memory.

At the time a 1080ti was about £650 so yes it was a bargain. Remember we have VAT at 20% and after Brexit the £ plummeted against the dollar so that went against us.

Whoa good luck with that £90 CPU LOL!! So you spend $600 on an RX Vega LC and run it on a $100 CPU? Each to their own I guess. What a waste well that's life.

I'm just glad we have that option! With a 4k OLED now it's really really tempting!

Ha beat you both,

November last year, £290 for a air 64 LTD which is $412

Ree · 1 Feb 2018 at 03:59

damn that is a right bargain, am happy at paying £488 but compared to that i feel ripped off lol.

Well, mine is the Liquid and I paid $525 USD. You got yours for about what MSRP should be. So, yea. Pretty awesome honestly.

Honestly got to say though that I love this card. Far less problems in games as for stuttering and such.

It still holds its own still. I got it with the plan to upgrade down the road, that it is was the more needed component due to the 780Ti showing its age. 780Ti = Memory limited. It was the cheapest premium card on the shelf at the time. The goal is to move to Threadripper this year.

Pound was crap then too, think it was 1.2 ish dollar to the pound, works out to $350 at the time. Should have bought 10 and flogged them ... :eek:

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

I use registry mod, 128MB no errors, 1024MB, link, 2048MB, link, 3000MB link.

Weird, i get errors on 2x Vega and an RX 580 on two different systems. I decided to check another system once i saw errors and started to worry that my Vegas might be faulty.

Thankfully no issues outside of this app though. Probably something simple, but i can't be bothered to troubleshoot it.

gupsterg · 1 Feb 2018 at 14:55

Added 3000MB. Dunno, just grabbed it from github while back. It was on my to do list for profile and when I saw your post I thought I'd run it. This REG setup I've had for ~2mths now. Done lot's of gaming plus easily 100hrs+ of F@H/Bionic.

*** edit ***

2x 3072MB runs, one with HWINFO and log, other MSI to show graph.

I've no idea. What i do know is I've spent enough of my life running CPU stress tests and Memtest tuning Ryzen and Threadripper/memory to optimum overclocks at low voltage.

I don't want to waste more time figuring out why this app throws up errors when running OpenCL tests on my GPUs at stock clocks.

I have HPET disabled, wonder if it could be that...

Follow up on my gaming with HBCC turned on

Over the last week or so I've been playing through the career in Dirt 4, I was doing some recording using Fraps as an FPS counter as I wanted to upload it to Youtube. I was in Wales on a late evening stage and when I moved into the forest area where there's a lot of shadows the fps dropped to below 30 which along with a bit of chugging making it very hard to play so I alt tabbed out of the game so that when I restarted I'd be able to do the same stage after I'd turned HBCC off (it's the only thing that's different).
I turned HBCC off and then I restarted the game and this time on the same wooded section of the same stage there was a 10 to 20 fps improvement with HBCC turned off. I'm running a stock clock Ryzen 1600x & Vega 64 PC. So there's definitely some games where HBCC has a negative effect.

NP

, was just sharing what happened with me using app

HPET in OS is disabled in my case as well, but as C6H/ZE doesn't have switch in UEFI an app can use it, link.

MemtestCL is not working at 4096MB :/ , will contact author for input.

*** edit ***

From some googlefu, it seems there is a limit on what amount of RAM an OpenCL instance can use. So I used 2x instances to reach 7GB total VRAM load.

During, link, end, link.

Will still be aiming to pick author's brains
