The RX Vega 64 Owners Thread

It doesn't reduce GPU core voltage at all unless you reduce the HBM voltage value.
...
FYI, peak additive GPU core power and GPU memory power values are ~192W under full load.

Oh wow, so this might make for a much quieter, cooler card. Can I ask if you adjusted the power limits or just the voltages to get here?
I've been tweaking the Core voltages and power limit to achieve cooler running, but with some reduced performance. I guess this is because the core voltages weren't actually being applied as I hadn't touched the memory voltage, and it was running into power limits. Hmmm, there's more to play with before writing this off as just a hot, noisy card then.

Honestly none as yet, but I am at the moment putting it back in a water loop. At £449 for this level of performance, absolutely no complaints at all.

I think, and this is me being completely honest, I would regret buying a reference blower style card to use without water, as the temps and noise levels are off the charts. And I'd definitely regret paying today's prices for that.

I was thinking that, my eyes were set on Vega 56 but I don't like blower style cards. But on the other hand if I wont get at release later the price will increase for sure.

To do 1630Mhz locked solid (stock boost) in benchmarks I need between +10% and +20% for stable, and with 1100Mhz HBM2 clock (stock is 945Mhz). It's at 950mV GPU core (down from stock 1200mV). At these voltage and clocks, it is stable down to -10% power limit, there is just some throttling; unlike Fiji which once you start overclocking (or making sure it doesn't throttle) will suck almost whatever power limit you throw at it, Vega it just seems to need the little extra occasionally. I think people are just used to Fiji and some extent Polaris - hence why everyone (including reviewers) are throwing +50% at it; completely unnecessary at least in my case.

My card, at these settings, lies about half way between a 1080 and 1080Ti (much closer to the latter in some games), and less power consumption than a stock 1080.

I suspect it's partly the bad early drivers and need of firmware revisions, but I have to step up voltage quite quickly even for 10Mhz increments above 1630Mhz. There shouldn't be the same kind of process 'wall' as with Zen, at these lower clocks - should be thermal limits. Will see how it behaves once on water, but I don't think the drivers and firmware are really designed to be efficient beyond the stock clock yet ...... and it is ridiculously efficient at stock clocks (HBM OC'd) once undervolted.

RE7 looks amazing wish i picked it up the other day on sale....

Does if play as good as it looks?

Yes plays lovely on Vega, so much better than playing it on the Pro Duo with only 4GB of HBM. This game drinks video memory for fun, saw 7.3GB at maximum settings (shadow cache on) at 3440x1440.

I've not really played it properly yet as i was waiting for Vega to get into it so i could max out the settings. I will start properly this weekend.

Does anyone else get a freeze of 2-3 seconds (not crash type freeze, just temporary lock up) every single time a Flash or HTML5 video initially loads in (doesn't happen after the player initially loading?
