The RX Vega 64 Owners Thread

I'm now happier with my air reference V64 than I was with the AIO version and so far my 650 watt psu seems to handle it fine. I was worried it was starving the card as it wasn't going up to 1600 let alone the stock 1630 mhz it's meant to be at but now I think it's more to do with temps as I've improved those and it now passes 1600. I ordered an 850 watt psu so tomorrow I'll see if it's any better with that as the stock clock should be 1630 mhz. Plus I'll see about overclocking once I have that installed. You're doing really well running all that with a 600 watter.

Considering the problems that others have described on here, I'm very happy with how things have worked out so far. Just wish AMD put more resources into driver development to get the quality better, quicker. Recently bought Civ 6 too - runs great on my system, and so I won't have any time left for tweaking :)

TBH the power draw of the 64 scares the bejesus out of me!

Just use Power save profile for tiny performance penalty compared to third lower consumption of card.

Who ever decided that "Balanced" setting deserves hard kick to butt.

...Be Quiet! Pure Power 10 600W...

I would expect the real world speed and stability of the voltage regulation control loops varies with PSU models, and the larger output capacitors in high power PSUs can somewhat mitigate a poorer response. I may have accidentally lucked out in getting a fantastic quality PSU, but I chose it as I thought it was a good deal at £65 earlier this year. It's only rated 80 Plus Silver, but crude efficiency isn't intrinsically correlated with other quality or performance factors.

You forgot to count in price of very probable need to replace it sooner than if you had bought PSU with quality components.

Lower end parts of second tier maker aren't good thing for longevity especially when cooling isn't maximized and efficiency is substandard.
The electrolytic filtering caps are provided by Teapo. Most of them belong to the entry-level SC line...

Damn RX Vega 64 is only 4 FPS @ 1080p and 8 FPS @ 4K behind GTX 1080 Ti in Wolfenstein II.:eek::eek::eek: I wish they optimized all games like this for AMD cards.

Hopefully its a sign of things to come. I want to see more devs start using Vulkan API though. I know Star Citizon said they was going to use Vulkan.

Thanks i tried all that before i posted here. It is on a clean win 10 install but maybe al updates have to be done with windows updates before installing these drivers. It hangs the pc :(

What motherboard do you have?

I had a similar problem, it turned out to be an issue installing vega on an older x58 motherboard which only had PCI-E 2.0

BF1 4K60 Ultra Settings Vega 64


1080TI for comparison on the same map and same settings.

Turning to custom and turning off taa as it's overkill for 4k, should give you 15-20 fps, which is solid for vega. But can't really compare mp, or with vega at dx11 and nvidia at dx12.
In those videos.

That's okay, thanks for pointing it out it was a valid point.

Vega performs really well on BF1.

Any chance of getting all the games Vega runs the best benched? I know this might be a little topical and will obviously get flamed as biased but I would be interesting see Vega in a best case scenario.

Component quality alone isn't enough to guarantee longevity; circuit design, component specification, thermal design and operating environment (amongst others) have a significant impact too. Of course higher temps shorten the life of electrolytic caps (a common failure mode, but not something I've had yet with PSUs), but your claim of my very probable need to replace it much sooner than otherwise is somewhat over egging it when you don't know the temps these caps are actually subject to. I expect it'll last far beyond 6-8 years, at which point it's not worth the extra of a top tier PSU, and there may be further evolution of the output connectors that are useful to have in a typical system at that time anyway.

I think you've missed the point of my musings - Vega has a high power draw but that alone isn't the demand on the PSU specification, otherwise I wouldn't be able to run my V64 fine on a mid-tier 600W PSU while others keep seeing problems with ostensibly top-tier high wattage PSUs.
