The RX Vega 64 Owners Thread

Guys, can I borrow your expertise on this what I think is a RX Vega 64 problem I'm having.

Problem: I'm getting a hard crash (full system power off and doesn't POST unless I take the power cord off for at least 30 seconds) when I play XCOM 2 game with War of the Chosen DLC. I've managed to save the game just before the crash happens 100% of the time (in case anyone else wants to test it).

System specs:
AMD Ryzen 7 1800X
AMD RX Vega 64
Asus PRIME X370 -PRO
G.SKILL F4-2800C15Q-32GVR
Windows 10 Pro 64-bit
1000W PSU (Corsair HX1000i)
Samsung C32HG70 (1440p 144hz Freesync 2) monitor
CPU and GPU are both water cooled, running at a maximum of about 50 degrees of celcius and should not be a heat problem.

What I've tried:
I've tried all levels of graphics settings from the lowest to the maximum - no difference to the crash.
I've tried 2 different AMD Ryzen 7 1800X CPUs and it has no effect.
I've tried different BIOS versions, including the latest 0902 with AGESA 1.0.0.6b.
I've tried with both Windows 10 Pro N-version and Windows 10 Pro versions, but only in 64-bit.
I don't have another AMD RX Vega 64 graphics card or another graphics card for that matter to test if this problem is specific to this individual unit.
I've tried with ALL different available versions of drivers for this graphics card, and it happens with all of them.

Please note:
I'm getting no crashes on any other game, including Witcher 3, Watch Dogs 2, Overwatch, Nier Automata and other modern games. I've also ran Prime 95 and all Unigine benchmarks extended periods of time without any issues.

I bought the RX Vega 64 on the release day Monday 14th of August and got it the next day (15th of August) from Overclockers. I also bought the Liquid cooling for my whole system including EKWB full cover block for the GPU from Overclockers.

If you guys have any ideas how to test the problem further or even solutions to overcome it: I'm all ears! Thanks!


Ive had similar problem with my system being able to run dx12 api and open gl api but crash resetting on DX11 api, and as weird as it sounds what fixed it was me swapping my 850 watt corsair power supply to my back up 700watt corsair power supply which im still using until i can afford a decent 1000watt
im using msi krait gaming x370 board and ryzen 1700. hope this helps dude because i know how frustrating it can get. :(

Thanks mate! I might be able to borrow a different PSU from work to test this out! (Not a quick thing with a water loop.) Wouldn't be the first when some weird glitch is messing up the rest of the system. Maybe there is a peak draw that goes beyond the 1000W (including capacitor charge??) or one of the power rails is not up to scratch.

However this PSU (Corsair HX1000i) comes with a Corsair Link program for measuring power draw etc. I've had it running side by side when the system is under load and it generally only does just under 500W max off the wall. There are odd peaks, but I don't think I've seen over 600W ever.

Thanks for the DirectX point too! I've ran all DirectX versions 9-12, Vulcan and OpenGL on different games and 3D modelling packages without any problems. But this again wouldn't be the first. I've personally managed to hard reset some of my older computers when programming something on a graphics API. Direct 3D 9 was particularly glitchy. Just a pointer with a wrong data easily gets the system's knickers in a twist. I don't think there is a DirectX 12 support for the XCOM 2 game yet (if there ever will be?) and the minimum is DX 11. However once Linux 4.15 releases hopefully sometime in November, I'll be able to test the XCOM 2 in OpenGL with the Mesa library. Unfortunately I have to wait for that.
 
I might have found out why my vega isn't pushing to full load in intensive parts of games, Can anyone tell me what the 2nd bios TDP is on the vega 64 ? Thinking maybe it's running on the 2nd one since my card never uses more than 250ish watt but normally sits around 200 even with the power limit +50%
 
The 2nd BIOS is 200W instead of 220W so not as good as the flashable BIOS.
Well damn, I'm all out of ideas, There's no logical reason i can think of why my card just refuses to act like it should. it looks like the power is there but just.. refuses to ramp up I mean look at this https://gyazo.com/e3ee694d2966ccc468591b705f2d411d Only word for it is unstable BTW this is witcher 3 in the middle of the main city area.

That's looking pretty normal for GPU load. Witcher 3 is DX11 after all and does seem to hitch a bit for keeping the GPU fully loaded. I've noticed a lot of games unable to keep the GPU up to speed. One of the reasons I use ClockBlocker to prevent the downclocking aspect which can induce stutter as the GPU ramps between the different P states.

Here's a comparison between Superposition vs Witcher 3. Superposition is the 100% bit at the start. Witcher 3 just isn't keeping the GPU updated with enough information. It's also limited to 60FPS for me (running Ultra). ClockBlocker is keeping the Core Frequency in P7 state and roughly around the 1620MHz mark for the most part.

Hmn strange, How come other people seem to be fine then but i'm the only one with very limited fps in intensive areas ? I mean DX11 can't really be this ****** up on the vega can it or is windows 7 the issue... hmn, Also how come your limited to 60fps ?

Yeah, this doesn't sound right unless you are using vsync or the framerate limiting option. My Witcher 3 runs around 80fps on Ultra.

Edit: but I'm on Win10

Oh it'd run over 60, I just haven't had time to work out why I've got 60 limited. VSync is off, but was set to Borderless Window. I'll look into it more when I have need. Currently it's not that pressing. Need to setup my CPU and RAM properly first.

EDIT: Found the way to switch to unlimited :)

Ok the issue is 100% windows 7, Every benchmark i've seen with 30% better performance have been in windows 10 64 bit, Even in DX11 on windows 10 the card works right, Gonna try duel boot windows 10 to test it out to confirm in a few days.
 
On a flipside, I got Witcher 3 to start playing nice. Disabled Nvidia Hairworks. Getting 90%+ GPU use with nearly all ultra settings and well into the 100+FPS range now. SSAO instead of HBAO+ too as that's Nvidia's other FPS killer in the game.

The Hairworks look so nice though :D

I'm still avaraging 80+fps with it on and 4x AA and I'm on 1440p.

I also do recommend using the Frame Rate Target Control on AMD's settings as I get well beyond 3000+fps in the menu. With the FRTC the GPU is pretty much idle in the menus: http://www.amd.com/en/technologies/frtc
 
Things usually run better with blackbox code off.
Oh indeed, I'm only at 1080p at the moment and was running with my 1950X at 3.4GHz due to new installation and just testing before getting some serious GHz out of it (still waiting on CPU Water Block from Swiftech).

@nlos Yeah I'll be upping the resolution when I get VSR running. It never quite worked right on the old rig and caused some massive slowdown in my Browser when opening pictures that used those java based albums for some reason. New Monitors are on the list (pair of 32" Samsung C32HG70's when they finally arrive in Australia).
