Well I defo not having the same experience has yourself with my VEGA. My GPU is in a decent size case mind you so maybe the extra space airflow is helping mine.

I wish I'd kept mine now and added a one of the AIO kits you can get for it, Especially as I've now moved into a bigger case with the 2700x.

I don't really understand how one can defend the Vega acoustics when one is underclocking from its base clock to maintain said acoustics.
People will probably be running Vega 56's at similar acoustics and better performance.

Ay? Since when was I undervolt to fix noise levels? I undervolt to keep temptures down and keep core and memory clocks consistent.
They is no change in my Vega from its balanced preset to my profile interms of noise. But I do get a much better performance because they GPU isn't hitting target temperature.
1600 rated speed on ref vega is only doable if you higher the fan speed to horrible levels. And that doesn't happen out of the box least with my Vega balanced preset the fan maxes out about 40/50%

I was the same for most of the time until I found that the Led on the GPU was bouncing all over the place. This indicates that the GPU isn't hitting the higher 3D clocks or memory is jumping up and down from 945 to 800
GPU memory temp and hotspot is what keeps vega in check keeping these two temperatures lower gives you a better core/memory speed that is consistent.
Why? what's the problem with that? It doesn't involve any extra software or any extra hardware. It's a simple tweak in the settings of the card. It might be different if you were reducing performance by underclocking, but, you aren't.
The noise was one of the main reasons I didn't get the reference model at launch.....
Just how much noisier would it be than my MSI GE 290? (which is undervolted to -31mV). Temps and noise wasn't too bad when I capped my FPS to 60 but since I now play with an uncapped FPS and on a 120HZ display, the noise, temps have jumped right up.....

Well if it's not running its 1600MHZ+ stock then it's being underclocked, running at 1500MHZ is underclocked? Running the stock clocks 100% stable would be better than a sustained 1500MHZ.

The card's throttling to hell then lol.
I'm happy with my Vega 64 acoustics and performance, but it can't really be praised.

I didn't underclock AMD's target rating of 1600+ is just a target and out of the box no ref vega runs at that speed unless you go into the driver and increase the fan speed beyond the stock settings.
At stock most vega will run between 1500/1600 stock but at balanced preset that will drop into 1400mhz and memory will drop based on temperature this is why you must undervolt Vega to make these speeds stable.
A difference between 1500 and 1600 is only couple fps even 1800mhz isn't really that much of a jump in performance vs the amount of voltage you need to push through the GPU.
I have fully tested vega ability to undervolt and how that retracts to core changes and memory. Vega is a really strange GPU. You can actually decrease performance if you overclock or undervolt vega wrong.
Sorry, I meant undervolt, which Shankly was talking about. The stock boost clock of Vega 64 is 1547 in turbo mode. It's less in default. If you set to custom and undervolt, you can actually get better performance at lower fan speed.

Vega 64's 1632MHZ stock (Although obviously it doesn't run that well out of the box)
That's either the liquid version or one of the after market versions. The Vega 64 reference boost clock is 1547.
Caporegime
That's what my Sapphire Limited Edition runs at stock.
I haven't altered it in any way. It's just a silver shroud reference card.
My underclocked undervolted setting is 1602 at 1000mv.
1632 is P7 and 1537 is P6.
That's when you go into custom settings. It's not the stock clocks.
Caporegime
Well, it kind of is? Running a game at default will run at 1630+ until it throttles to P6.
GPUZ picks it up as 1630MHZ (Which is what it'd be set to, but 1630 turns into 1632 if entered manually, same as 1500 turns into 1502 etc etc).
I didn't realise the P7 clock isn't reported anywhere though in the media, that's interesting.. But my Vega 64 certainly runs 1632MHZ at default settings. It doesn't hold it unless tweaked though.

It's not the stock boost clocks. Can post links to reviews, specs whatever you want. Specs are stock clocks - 1247, boost clock - 1546 for Vega 64.
Caporegime
So it's meaningless that the card has a P7 of 1632MHZ set at stock settings? Those speeds could be maintained if power/heat is kept under control. Does that still not make it 1632MHZ stock boost?
I'd have thought the fact it runs 1632MHZ at default settings would make it the stock boost.....
The P7 settings only come into effect when you go into custom settings. They aren't the stock settings.
