My experience with Vega 64.
Written by: bluej511 - 09:51 Sep-03-2017

An honest review about Vega 64. 

 

All i can say is the card is an absolute BEAST, it eats everything i throw at it and then some, yes drivers are still a bit buggy but hey so was Ryzen at launch but look at it now. 

I had it on air for about a week or two just to make sure there was no issues. Unfortunately while doing the first driver install my PC crashed and seems to have messed up a few things along with it so i did a fresh install of W10 and everything has been perfect since. 

The card looks so beautiful not having anything on the PCB.

 

And here it is inside with distilled water. 

And heres a shot of the bare card. 

And one of the interposer. 

 

Excuse the quality i used my s4, would have loved to use my DSLR but was too busy cleaning out my loop. 

 

As far as temps go, heres the before and after. This is with a case ambient sensor showing 25-26°C today and the water peaking at 34°C. Peak temps are shown. 

Core: 85°C/39°C

HBM2: 91°C/44°C

The clocks on air would fluctuate quite a lot and go from anywhere between 1138 to 1630 (depends on the game, Rocket League only stays  at 1138 and still hits 75fps maxed out no problem haha). On water it stays closer to 1536-1630 with it averaging closer to 1600mhz, HBM keeping at 945. 

 

Now as i am waiting for more mature drivers i have not yet tried to overclock and undervolt the card but it will run the HBM memory cooler as well. Most people with 64 seem to be getting at least 1000mhz on the memory while undervolting it as well. 

 

Any questions or comments feel free to ask (for those wondering thats a 5.5g tube of Kryonaut, made more sense buying 5.5g then 1g for half the price)

 

For anyone interested, heres water on the left and air on the right.

nice bro. The temps you mention are before and after the loop I assume right?

I had the loop already (was running it on my r9 390) but for a week or so it was just running on air as i was waiting for ekwb to make more Vega blocks. All i did was clean the rads, empty the loop. then added the gpu back into the mix. So yea the temps are the before on air (so pretty much FE type temps) and the after is with the card back into the loop. Thats with a 1700x into it as well (which having to remove the cpu block and clean its also running Kryonaut as well). Shocking temps.

Also to note, the r9 390 would peak at around 45°C this week but today has been 4-5°C cooler then a few days ago, also cleaning the rads. Id say the temps are comparable. With cooler temps around the corner though temps should drop even lower.

Thats really nice. If i understood that correctly you use a 360mm and a 240mm block ? What else is in your loop? And what pump do you use?

Id list the whole thing but pita ill do it later haha. Running a D5 pump with 150res at 75% at all times (its not even audible), a 360 with 3 noctuas in push 2 enermax in pull and a random antec. The 240 has 2 Tt case fans in push and an enermax tb silence in pull (random fans i have laying around might as well use em), 3 noctua 140mms as intake fans up top and 1 150mm noctua off my NH-U14S as exhaust, case is a Core X5 cube case. All fans at 1200rpm its pretty silent.

Other components in the rig are the 1700x OCed to 3.8@1.225v under load, 1.262v at idle with a supremacy evo. Im surprised that its keeping temps as cool as my r9 390 was with an alphacool block (that thing is WAY restrictive too). I did take it apart for the first time in a year to clean the dust and drain the loop.
