The RX Vega 64 Owners Thread

[Martini1991]

The P7 settings only come into effect when you go into custom settings. They aren't the stock settings.

But the clocks are set? They exist before you go into custom because GPUZ picks them up.
Again, if I run the GPU at default and run a game, it runs the set 1632 clocks until it throttles, because the P7 exists and works.

Regardless of the "spec" they're set at 1632.

AMD might list the P6 boost speed (Which is probably more accurate given its out of the box setting) but they're all P7 at 1632mhz at stock on reference cards.

So let me get this straight, You are arguing against both the official specs and what the reviews say the clocks are. The clocks are 1247 and 1546Mhz. That's the facts.

AMD just picked that 1632 figure for their P7 State, they could have picked 1900 if they wanted, It doesn't matter because the card isn't going to run at those clocks in the 3 default modes. Sure it might start off at 1632 while gaming, but, it will soon settle down to the default clocks. It might boost a little higher based on how cool your case is or if you are running the fans at 100%.

AMD could have picked a P7 state that it's actually capable of running? Saying AMD could have went higher to an unreasonable speed isn't a rebuttal (Then again, I don't think it's capable of maintaining P6 speed at default settings)

End of the day, the fact is that the GPU runs 1632MHZ at default settings. It can't hold it, but it's certainly factually set at 1632MHZ. For some reason this isn't considered a stock boost speed.

Bonkers.

Do you consider my GPU at 1600MHZ P7 at 1000MV that it runs 24/7 to be overclocked then? Despite the fact I've lowered the core clock setting? Is that 1600MHZ now considered to be my boost speed?

AMD did pick a state they were capable of running. They are the default clocks. The P states that you see in custom settings, don't affect the default modes at all.

End of the day, the fact is that the GPU runs 1632MHZ at default settings. It can't hold it, but it's certainly factually set at 1632MHZ. For some reason this isn't considered a stock boost speed.

Sorry, wrong, at the end of the day, the stock boost clock is 1546. All of your misunderstanding of the situation doesn't change that. Look at the specs of the AIB cards on the store page. They have custom coolers and they have the boost clocks set at 1609, 1611, 1560. How can you expect the reference cooler to achieve higher boost clocks at stock settings?

Bonkers.

Why? because you refuse to accept what both reviews and official specs say the default clocks are?

Do you consider my GPU at 1600MHZ P7 at 1000MV that it runs 24/7 to be overclocked then? Despite the fact I've lowered the core clock setting? Is that 1600MHZ now considered to be my boost speed?

What? You haven't lowered the core clock setting, you have just lowered the P7 state. Running at 1600Mhz is overclocking because the stock boost clock is 1546Mhz.

Edit : What's the point. Apparently set clocks are to be ignored because "reasons".

 

[AmateurExpert]

I think Martini1991 is correct - the stock boost clock on my Ref V64 is 1632MHz, and PCPer isn't exactly a shining beacon of accuracy, transparency or competency.

I noticed at launch that the published specs up to that point didn't match the actual delivered cards.

No write your post, I want to see what you are saying. You are the one ignoring the default clocks for "reasons"

The stock clocks are on the websites where you buy the cards (no reference ones for sale, so I just used the closest AIB one)

https://www.overclockers.co.uk/giga...hbm2-pci-express-graphics-card-gx-19n-gi.html

They are listed in reviews

https://www.pcper.com/reviews/Graph...-Review-Vega-64-Vega-64-Liquid-Vega-56-Tested

They are listed on the Radeon Website

https://gaming.radeon.com/en/product/vega/radeon-rx-vega-64/

Yet, despite all that, you think that the stock clocks are 1632.

Why can you not understand that the custom setting are custom settings? They aren't the default clocks.

Boost clocks aren't static things either, they are dynamic, change with temp, power, load.

Yea according to techpower the stock boost is 1532 and that is only if the temp's are kept in check.

Here is a statement from pcper about Vega and clock states between 56/64 and LC 64. So Melmac is correct in what he is trying to get across.

The Vega 64 Liquid has the highest sustained clock speeds and averages 1663 MHz over the course of our Unigine Heaven loop. The standard Vega 64 averages about 150 MHz lower at 1513 MHz and the Vega 56 brings up the back with an average clock speed of 1433 MHz. If we compare that to the rated clocks of the card from AMD, which we now know are supposed to represent the “typical” clocks users will see while gaming, all three are lower than expected. The Vega 64 Liquid is rated at 1677 MHz, with our results just behind that by 14 MHz. That difference is within a reasonable margin

That 1632 figure is just a peak that it will try to boost to.

All these sites can't be wrong.

@melmac is correct
Vega speeds are just target speeds.
NVidia rate there speeds different to AMD. Boost clocks on Nvidia is the speed the GPU will least run at any higher is boost.

Let's guess even Amd is wrong? From amd site
Boost Frequency1546 / 1677(liquid)

 

[Martini1991]

The "official" boost is obviously taken from the P6 reading, this will be the same for the AIB's.

But the P7 clock is 1632MHZ, and is active, the cards (At least the reference) can't maintain them at stock. I can't just pretend it doesn't exist to fit narrative.
Regardless of it being the peak, it's still active, it is the default setting the card will go to first etc. For all practical reasons it is the running stock clocks.

You don't change any settings and the card will run at 1632MHZ initially, because P7 is an active state regardless of any settings in Wattman being altered, and that state has 1632MHZ as its stock clock.

I'm absolutely fine with AMD using P6 as their official boost reading. But in practice its set at 1632MHZ.

 

[Martini1991]

If my p7 state 1632mhz ran at lower voltage and the fan was higher. The GPU would stay at p7. Surely this makes it the stock boost? My gpu can run the already set p7 clocks, the problem lies with voltages and fan speed, both of which can be changed.

You told me that I underclocking my GPU because I running at 1500 this isn't true. I am running at its rated speed for none liquid version. My actual speed is around 1580 because of undervolt that I have so in fact I am over the rated speed for the air cooled version.

If I was running liquid then my stock speed would be 1600+

This is just vega boost speed it is designed to achieve if the cooling is correct.

Take a NVidia GPU for example a 1080 rated at 1800 out of the box they known to boost higher would you say this is that cards stock speed?

You said you were maintaining 1500mhz unless I'm mistaken.

I'm on about default boost. P7 is set at 1632mhz however AMD list the P6 state as the official boost. It makes no sense. P7 is active and it initially runs 1632mhz.

I don't even care that it doesn't maintain 1632mhz, i don't understand why they didn't just set the p7 at 1546.

I'm not sure where nvidia comes into this. The scenario isn't the same. But I understand why you've decided to use an Nvidia example

I said 1500 because it was just a base line if you read one my other posts I do say it remains between 1500/1600.

Not sure but you also understand?? What one is it?
The p7 state is just there for the GPU to boost into if the cooling is correct. It is not the advertised stock speed.

I've never claimed its the advertised stock speed, but at stock it will run 1632mhz initially until it hits problems and then goes to p6 or does the core clock just throttle?

 

[shankly1985]

That's expected because you now giving the GPU enough cooling to just boost has much as it can.

I've never claimed its the advertised stock speed, but at stock it will run 1632mhz initially until it hits problems and then goes to p6 or does the core clock just throttle?

My Vega only does p7 for couple mins into a game. Soon has my HBM hits around 70/80c it will drop into p6 and remain.

If I don't undervolt my GPU bounces all over the pstates

 

[henson0115]

martini is correct, however it appears to be temp based. noticed this quite a bit actually. note my chips has no problem running 1700 on air without any issue at around 70 degrees when overclocked.
