Is my vega 64 dying or psu not enought

[Ramune4fun]

Hi,

I just bought and liquidcooled my vega 64 and bcause I am stupid i didnt test it before putting on the waterblock

So when I start my PC sometimes it runs well on the Desktop and sometimes it lags a lot.

In any of these cases after some time i get a black screen but than picture comes back on and graphics drivers reset.

The bigger problem is that running games is impossible.

E.G PUBG i get into a game everything is fine (~80fps) but after 5mins blackscreen driver reset game crash.

I used Redeon Overlay and hardware monitor and it shows the gpu was under 100% load and consumed 200 watts and temps below 30 °C.

What I already did:

-Ddu and driver installations.( several times with different drivers)--> problem remains

-Windows 10 clean install --> problems remains

-testing on 700 watt psu --> problem remains

- tested system with gtx 1080 -->everything works fine

 

My specs:

Ryzen 1800x

16 GB hyper x 2133mhz

Aorus b450i pro wifi

600 watt bequiet 80 plus gold

Intel 1 tb ssd 

Saphire vega 64 

I kind of thinking the PSU might be the problem but I already tested the System with the 700 watt psu...

But i think that is not enought ( even thought the psu only suplied the gpu alone but still the rails might not have enought)

Your PSU is enough. I can tell you that. I once ran Vega 64 and i7 8700K on CX450M...

 

Further than that, I cannot give you much advice.

Try undervolt the thing and test again. 

 

I think GPU-Z can show hotspot for Vega, try check that too.

i assume a pure power 10 or 11?

Install drivers again after removing all old ones in safe mode with DDU.

You're a brave man

Certainly isn't an issue with the power supply, especially considering it had the same issue on another unit. Almost certainly an issue with the GPU. Did you buy it used? Have you tried running the air cooler for testing purposes?

I had such issues after I've used Conductonaut on my 1080Ti. I'm 120% I didn't short anything with it because I used regular thermal paste to insulate capacitors around the GPU just to be sure. Removed it all, cleaned it and used regular paste. Not a single issue since. I don't know what was going on, but I'm back to regular, but top of the line thermal paste...

Tried that and the hotspot is aswell around 35 °C this card never geht's any demanding things before the driver resets

Nope and with air cooler same probs

(The most difficult part about that was to buy these stupid pads  )

Is conductonaut the liquid metal? 

I didn't use that just normal paste and should i put some on the capacitors?

SFX power or SFX-L Power??
That one should work with VEGA...

It is that one :

SFX -L Power

that should work...

But do you have access to other PSU?

Yes I have that one from another system:

be quiet! Pure Power 10 cm ATX 700W PC Netzteil BN279 mit Kabelmanagement https://www.amazon.de/dp/B01MY98DMP/ref=cm_sw_r_cp_apa_i_J-8NCbNR4CHDA

It is 1 year old or so but it works fine in my other system but with the Vega card installed problems still occur.
