Yesterday night I finished building the custom water loop on my Vega 64.
I started building stuff late in the evening and it got quite late until 2:00 o'clock.

I did only one test so far. I played Witcher Wild Hunt for around 40 minutes leaving the Wattman settings at default Balanced mode.
I was able to achieve average clock of around 1528MHz with the GPU temperature staying on average at 39°C at room temperature of 24°C. These temperatures are great. :peace:
The maximum temperature of the GPU was 42°C. The maximum GPU frequency was 1630MHz.
The frequency measurements were done with Wattman as well as GPU-Z.
I will repeat the test tonight and make some screen shots as I did not make any yesterday.

This result is very close to what Tom's got in the Witcher with Turbo mode.
In my case the Wattman is on balanced mode and I achieve average of 1528MHz in Witcher.
I will do further testing tonight with Turbo mode turned on to see how high the average clock can go on my Vega 64 sample.

I bought a Saphire aircooled Vega 64. It is a variant where the GPU chip and HBM2 have same height and there is Epoxy filling between GPU and HBM2.
I used IC Diamond 7 Carat as thermal compound on GPU and HBM.

The undervolting test will come in the next days.

With original cooler it was hitting 85°C all the time with default fan profile.
To achieve lower temperatures in range of 65°C on the blower cooler, the fan speed needed to be increase above 3300RPM.
It was like sitting next to a Vacuam cleaner!!
The average clock there with high fan RPM was always below 1430MHz.
I did further tests concerning this topic.
I put the results in the Owners club section here:

The results look very promising. :cool:

Ha,some clowns over on Linus Tech were trying to argue that for the price of the Monsta 420 AIO you could build a custom loop.
Well custom water cooling is quite expensive, especially here in Germany. I don't how the component prices in other nations are.
Counting the cost of my pump plus reservoir, 3 radiators, 5 fans, GPU and CPU water blocks, coolant, fittings and tubing, I arrive at a cost of around 750€ just for the custom water cooling loop.

And that's all just swell, but it doesn't change what I said.
I didn't really contradict anything what you said, I just used your post to make a point. But nvm, I'll make sure to never talk to you again. ;)

@turbogear can you stop the multi posts everywhere? There's a edit function built into the board.

there is nothing promising about offering 80% of the performance of a gtx 1070 @ 150% percent power consumption

this is like giving out a 'you tried' trophy

I can make a Honda civic go really fast with enough boost,money and jbweld
that doesn't make it a GTR

Terrible analogy. For the money SEVERAL Civics can be just as fast or faster . Are you calling Vega the GTR?

and those civics(vega) need how much work and how much air/fuel to be as fast as a gtr(pascal)
at the end of the its still a civic its still front wheel drive its still small and its not as nice as a gtr

You're comparing a $100,000 sports car to an economy car, it's silly. However, I will entertain you, a K-swapped Civic can run 11s naturally aspirated for less than $10,000. A boosted Civic can be a lot faster for $30,000. Again, this is a dumb comparison. A lot of people don't even care for a GTR, current models are ugly in my opinion even if they run 11s. I'd rather have a Tesla that's just as fast, better looking and more economical.

Right well vega just needs a software update, thats going to take time but wont cost a dime.
Its a poor analogy Onemoar.
And I get what you're saying but a 1070 wasn't for me personally ,it wouldn't have beat the vega in my use case ,and using freesync tied the deal.

Vega 64 is clearly faster than 1070 or am I missing something ?

You're not missing anything. OneMoar is however missing a whole lot. He doesn't realize that Vega 56 and 64 are like GTRs that weren't ever tuned from the factory(LOL) and now consumers are adjusting the air/fuel ratio to a nice 12:1 and getting a large amount of performance increases. Still, the pricing is so jacked up that a 1080ti still looks like the Bugatti Veyron or some other Hypercar while costing the same, I figure he'll understand if I use cars.
