Does my LC Vega 64 have enough POWER??

So I just got my Vega 64 Liquid Cooled edition, hoping I could get close to the best performance. But every time I try to overclock and/or undervolt it and raise the power limit, either during stress test or game play (both), the screen will go black and it will show all kinds of colors in like a square shape. What I'm thinking, is that I don't I have the power to supply it. Powercolor recommends a 1000 watt PSU (I know a better quality 750/850 will probably be fine). When I do slight overclocks and undervolts without raising the power limit my screen will just go black and the Radeon/Afterburner (tried a few) will just reset to default settings and the screen will come back on. Again, that's when I don't raise the power limit.

 

Am I correct to assume this is a power supply issue? I just want other opinions before I invest more money.. If so, 750 Gold or 850 Gold? Seasonic Focus or G3/G2 (g2 if close to same price). I went with the 650 Gold because originally got the Vega 56 and was told that was plenty, now I think I'm in a different ballpark...

 

 

This is what it kind of looks like when raising the power limit too high, whatever window is currently open turns to like lines and completely black (sorry It happens to quick to take a photo) and then it pretty much freezes and I have to hold the power button and reboot.

what about removing the CPU and memory overclock first?

 

oh and Vega lose stability easily past 60C, so keep that temperature low.

650W psu should be way more than enough. I think the 64 in a whole system would take about 450W MAX. <- that is a whole system power draw. your psu is not the problem.

It was overheating the way I put the radiator first but now that I moved it, it stays under 60c almost the whole time while gaming.

 

I was trying it without the overclocks on the CPU and Memory at first, since I just changed my motherboard and had to re-enter my settings (which I entered after I kept failing with OC/UV on the Vega). I was going to focus on just the Vega this time since I knew what the other components are capable of.

 

Like a lot of the guides on overclocking say set the power limit to +50%. I can't get the memory to go past 980mhz and people without LC are claiming 1100 on the memory and mine is running cooler than theirs. I know I can't overclock the core/gpu much higher than around 1700-1750.

 

Right now in Afterburner I have:

-12 undervolt

+15% power

1750 MHz Core Clock

978 MHz Mem Clock

 

And I'm playing CSGO right now and waiting for it to crash, I'm pretty sure it did when I stress tested it.

I know this is high but this guy got it to 610w (total system not just gpu)...and an Intel system..Not sure which uses more power..

 

Like I can't even get a good common undervolt/overclock that most people are getting with air cooled and this is supposed to be a better binned/quality chip.

check the thermal paste application then, HBM doesnt like heat and Vega has problems of stock paste not covering up everything.

In HWiNFO it says the max HBM temp was 54, just while gaming.

 

And how would I check that, by taking it apart?

You think that's still necessary if I stress test it without an overclock and it DOESN'T reach 60 degrees?

 

Also, you don't think it's a power supply issue?

it's possible that the stock paste didnt cover up the corners. The thermal sensor will be somewhere on the middle.

 

Power supply could be a problem, that's why I said you should test without CPU overclock. AMD put the stock Vega 64 LC at 345W TDP, without raising the power limit you should be around there. Keeping the 2600X at stock keeps the power draw at around 125-150w, which then allows the PSU to be more than sufficient.

Okay, I'm going to reset BIOS to default and only apply the Memory Profile (XMP), that should be fine right?

The point in undervolting is to decrease power draw, which reduces heat, which allows for higher/stable overclocks, right? Since I have a liquid is it ok if I don't undervolt, turn power up a little, put my clock around 1700 and mem around 1100? So far that's working for me but I'm not sure if I'm missing something on the undervolting part. I'm going to try to to lower it a little bit and see what happens but I'm just curious anyway.

 

What's more important, undervolting or turning Clock and Mem up? A little bit of both? What if you don't care about power consumption?

 

The PSU seems to be fine, for now., although the card can reach 400w. Is 650 enough if I overclock my CPU, too? I can't figure out how much my entire PC is drawing.

@Jurrunio

??

 

I turned off all overclocks on CPU and this is what I managed with Afterburner:

Core Voltage: -50

Power Limit: +25

Temp Limit: 70

Core Clock: 1700

Mem Clock: 1100

 

Runs stable in Uningine Superposition so far, at 1080p Extreme presets, with no artifacts that I can tell. PSU peaks at 330-380 watts.

 

Does that leave enough headroom to overclock my CPU on the PSU?

only to a point since obviously too little voltage can still crash your GPU. Vega does have high stock voltage though so there is some room for that.

I myself usually crank the power limit all the way up to remove clock bounces, and instead use voltage to limit the power draw and hence frequency.

On Vega, memory is everything. A card that has only overclocked its memory will beat one that's only overclocked its core, even if you decide to go the Gamers Nexus way and push 400w through it with increased voltage.

2600X at 1.42-1.45V draws about 150-175W max, so there should be enough power budget.
