RX Vega Owners Thread

by the numbers a 450 watt PSU should be good enough.

I'd advise NOT overclocking the Vega 56 or modifying the bios with that power supply though.

When a PSU is pushed too hard, to the point of failure, it can take out motherboards or graphics cards with it.

but say between 50-100 watts for your motherboard and CPU most likely, then a couple hundred for Vega at default settings. Add in 10 or 20 more watts for hard-drives and that's about it. Probably shy of 350 watts of draw in stock balanced settings in game.

So yeah, it will probably work. I'm just saying, that is cutting it close. But you're also talking to a guy that buys a 1500W PSU just in case.

But good point in showing that graph that a 450 wouldn’t be enough for an overclock or Vega 64.

Smitty2k1,
Why don’t you upgrade your PSU? Newegg’s had some good deals on power supplies lately. You can get a gold rates thermaltake toughpower 750 watt for $50 bucks right now, or a seasonic 620 watt for 35 after rebate. You know you’ll be tempted to overclock that Vega 56. It’s literally just a slider bar built into the drivers.

Archea!!! is this what you were looking for?
It’s one solid step forward.

However it’s something that should never have been released as broken. Examine this list of fixed and known issue. It speaks for itself. Most of these things are AMD owned problems, which truly shouldn’t exist on a competent production (non beta) software release from a giant worldwide company.

This spells out in detail exactly why I rid myself of these cards. We are 2.5 months in since launch and their still fixing very basic universal windows functionality bugs and game crash issues - not targeting the rare one offs that you’d expect at this point.

I'm running in an M1 Ncase mITX case so I need to upgrade to a SFX PSU. There are 500/550/600W models available around the $100-$125 price range.

Going to test what I got and if it can't handle it then upgrade. Like I mentioned, it has been running my 4770k and GTX 780 superclocked for years with no problems. It is a very high quality PSU on a very high quality Mobo Asus Impact and just one SSD, no HDD or ODD.


But yeah, getting that overclock itch...
 
There is a low power bios firmware switch on the card if it comes to that. It’s by the pci-e bracket. Pushing it toward the right end of the card uses about 10-15% less power IIRC - at very little performance loss. Tomshardware had a good write up on it.
 
Vega 56 up and running just fine with the SFX 450W power supply. It took a few adapters, powered using the PCIe cable and a Molex cable with adapters.

Ran some benchmarks (Ashes, Firestrike, Timespy, Heaven) with no issues. Scores were a bit lower than published review scores so I need to investigate that.

I also plan on flashing the 64 bios and undervolting.

Initial thought is that during benchmarks this card is louder than my GTX 780 w/ blower cooler, but while gaming and driving my 1440p ultrawide monitor it is quieter.

it is a vega 64, 650w should be enough, processor is a 7700k on a gigabyte z270-n gaming 5 motherboard updated to bios version F5, ram came off an earlier build of mine which ran fine and continues to.

Why do people automatically blame AMD or their Vega for problems/crashes when they don't even follow minimum requirements? Minimum power supply for the RX Vega 64 Air cooled is 750 Watt power supply and 1000 Watt for the Liquid Cooled, And that is if you do ZERO overclocking, which includes the processor. If you overclock at all, that minimum goes up.. I wouldn't use less than a 850 watt power supply for a RX Vega air cooled, and 1200 for Liquid cooled if you want to overclock. Your 650 Watt power supply is the problem. Also, pay attention to Amps on the rail or rails of the power supply you purchase.

I use a 600w SFX power supply just fine on a Rx Vega 64 LC. Now I would not recommend using the performance settings, balance is fine. Pulling less than 450w from the wall in most cases. I could only see needing 1000w if I was CFX two cards.
 
I've got 2 Vega 64s with a 1000W PSU. I seriously doubt you would need 1000W for 1 card.

The Vega is power hungry.
Max during benchmarking at the wall is 570W with the OCs in my sig for my GPU LC Vega64. I'd say at worst I could see 750 W if any game could manage to push both my CPU (max 230W during stability testing) and GPU ( max of 570W during stability testing/benching). Keep in mind that is at the wall and with some overlap for power usage, hence only 750W at most and not = 230+570.

The people you see above are using quality power supplies.

Why do you not understand that all silicon is not equal? Meaning that they all do not pull equal power, just as they all can't run at the same speeds. I have an RX Vega liquid cooled, total system power under full GPU load during gaming is between 730 Watts and 900 Watts (measures from the wall) Game/Cpu usage dependant. There are people who hit higher, others lower with less of a system then I have in the various discussions I have been involved in.

Every time I have seen people bitch about problems with crashing etc it ends up being somebody trying to run there Vega on a powersupply lower than recommended and/or ignoring the amps on each rail and overloading it.

You can sit and spin it anyway you choose, but if a person's Vega is causing crashes, reboots, etc and they are running below the recommended power supply, you can bet your ass, it is the cause.

But of course, there are always those that think they know better than the manufacture and go against it, and some succeed, and others don't and want to blame the hardware instead of themselves for not following the recommended minimums.

Same here. I always go above, and always keep in mind, there is more power being used than just what the GPU and CPU draw, there are hard drives, fans, pumps, motherboard, etc.

People also have to factor in envirement temperature which effects power draw of every device and power output of the power supply. Heat causes resistance. The warmer the air, the more power a device draws, and the less a power supply puts out, hence the main reason recommended power supply ratings are generally higher than what is calculated. So there is headroom for envirement temperature changes.

I should - after a marathon gaming session of SCII and Civ6 yesterday I noticed that the fan is pretty silent during game play but cut-sceens (SC2) and leader animations (Civ6) ramped the graphics card waaaaaaaaaaaaay up. Temperatures did not seem to correlate to fan speed in these instances. Do you have a suggested fan profile?

I did have one hard shutdown early in the day with SC2. The motherboard bios reported a shutdown due to surge protection. I put the Vega in power saving mode (instead of balanced) and didn't have any issues after that. I'm going to experiment with undervolting short term, but longer term will probably replace my 450w silverstone with either the new 500w or 650w or the Corsair 600w

W.U.T!! 730w to 900w??? Some hit higher? I would like to know what is drawing all that power, CPU? Number of hard drives etc. That just seems way out there.

Yes agree, if you have issues and your power supply is below suggested - might want to try a different power supply. No real issues but really the whole system besides the Vega 64 LC is rather power friendly here.
 
If you're going to go through the process of replacing the PSU, get something legit. Don't cheap out. I would recommend 750W.


Yeah a HXi 750 corsair, should be able to get it for around 120 bucks on sales. Comes with a 10 year warranty too.
 
And you're running Vega LC. Congrats, you overpaid for performance!

Now, if you were being honest, you'd list everything being measured at the wall, and the efficiency of the PSU you're using.

And if you were really being honest, you'd explain that watts are more of an arbitrary way to measure things, and what's needed is to understand the amps being pulled by the 6-pin and 8-pin connectors, and whether a power supply can provide them stably, regardless of overall wattage ratings.

Let me get this straight, you don't agree with my comment, so you resort to making fun of my purchase, and then attacking my honestly? So now you expect me to list all my hardware, my power supply, it's efficiency to validate what I said, in a very sad attempt to try and discredit what I stated? Then you try to make yourself appear smart by talking about amps and saying watts in arbitrary and overall wattage rating doesn't matter. When in all reality wattage of a power supply is AMPS X voltage. Since we know the volts, and we know the watts, amps is just a mathematical equation away. And since this whole time we have been talking about power in the form of watts, why in god green earth do you expect me to start giving details by amps other than trying to make yourself appear smarter then me? (you might be, you might not be, I really don't care. It doesn't change what I have stated to be true about running a power supply below recommended requirements).

How many amps the rails of the power supply is what matters in the long run, hence why I mentioned it in my comments. Most 650 watt powers supplies has either single rails or combination of rails that add up to 54 amps total. Vega 64 AC pulls 24 amps on balance and spikes to as high as 31 amps. Liquid cooled pulls 29 amps, and spikes to 33 amps on balanced. https://www.pcper.com/image/view/85437?return=node/68291 (yes you have to do some math to get the amps) If you set your power limit to 50%, those numbers go up quickly. If you overclock, they even get higher, unless you have silicon that allows you to under volt. this means that if you are trying to use a 650 watt power supply (even a high quality +80 titanium which is 94 % efficiency at 50% load and 91 % efficiency at 100% load) You are going to be using be using 44% to 57% of the power supplies total amps for just the AC Vega. and 54% to 61% for the LC Vega. The rest is for the CPU, cooling, fans, hard drives, lights, what every else you may have in a system. Depending on the age of the power supply, it's efficiency and power output could be less. There are other factors that also effect powers output of a power supply, and you have to remember that all ratings of a powers supply, including amp output is under ideal conditions (clean power, temperature, etc). We don't live in ideal conditions, sorry.

Now I get it, you don't agree with my statement about running a power supply under recommended requirements, and that is your right, but it doesn't make my statement wrong, nor does it give you the right to start questioning my honestly or expect me to list my hardware because you don't agree, I do not need to validate myself to you, or anyone else to get thru life or to state facts. And the fact is, if a person is running a powers supply under the recommend requirements and is experiencing crashes and system shut downs, it is not the GPU causing it, but the power supply regardless if it is high quality or not.

That is at the wall, so actual watts for the system after power supply efficiency calculated in is 670 to 820 watts. My CPU is a xeon 5675 (6 core/12 thread) overclocked to 4.35 Ghz default is 3.06 Ghz, water cooled of course. yes it is older CPU, and not the most power efficient compared to today's CPUs, hence why there is such a large gap between wattage at the wall. Low CPU utilization games draw substantially less power. There are some people I have talked to their systems draw over 1000 watts using the Vega, but I don't generally start grilling them about all their hardware or if they are overclocking etc. I also assume the majority of people who visit forums like this are not just your average joe's with average systems, which means they are usually overclocking and pushing things beyond just the norm, hence, the comment about power supply causing the problems.

But you don't assume that those using lower wattage power supplies aren't cognizant of the limitations thereof and thus aren't undervolting and limiting clocks in order to maintain a stable system instead?

Please!!! Stop!! You can't seriously be that naive, can you? People don't go.. Gewiz, I have a lower wattage power supply, I think I will buy a Vega 64 (power hunger card) stick with my lower power supply and under volt (if my silicon can, since not all are stable under volting) and limit clock speeds so I can ensure my lower powered supply can handle it instead of buying the proper size power supply, and when it crashes blame the Vega 64 and AMD. Stop trying to find every possible way for it not be the lower wattage power supply that is under recommended requirements causing the problems, and admit that IF a system is crashing using a power supply below recommended requirements that it most likely is the power supply causing it.

Yeah, I learned a long time ago to never skimp on the power supply again. That is why I was using a Seasonic 1KW on a 2 x Fury non x with an FX 8300 overclocked. I still have that power supply but now I am on a Ryzen 7 1700X with a Vega 56 and have no concerns with the power supply, whatsoever. :)
 
650w should be good enough. but you guys with the sff need to realize that not all sff cases can support the absolute best/hottest/most power hungry parts. there needs to be a trade off somewhere...

I think it has been beaten to death that PSUs in this wattage range are fine for today's top end (single) graphics cards.
 
I think it has been beaten to death that PSUs in this wattage range are fine for today's top end (single) graphics cards.
Except the very reason the discussion came up is it isn't, when a person with a 650 watt power supply (high quality, brand new) has to run his card in power saving mode to avoid system shut down and other crashes/issues, making it clear it is a power issue,, and tries to blame the card and AMD, all while ignoring their minimum recommended requirements.

But.. each to there own. If a person wants to cripple his investment by running it in power saving mode and not being allowed to use it at it's full potential because the person doesn't want to admit it is a power issue, or others trying to argue it couldn't possibly be the power supply, so be it. Not my problem.

I have never had an issue do to power, but then again, I never try to get by with what should be enough, and always get above the minimum requirements per the manufactor. Becuase what "should be enough" does not take in account for all the variables that can effect the draw on a power supply, or the output of the power supply. All it takes for a "should be enoigh" power supply to be a " not enough" power supply is live in an area with a bad power grid that is not effectively supplying clean power.

im not having any temp issues, perhaps i just lost the silicon lottery. my next option i suppose is to undervolt slightly, could anyone explain how that works and what that will do for me?

I undervolted my WC/LC Vega64 20-37mv and that lowers temps a touch and helps maintain boost clocks. The 20-37 part is the difference between Wattman and Afterburner. Afterburner seems to be a bit more stable using lower clocks hence the lower 37mv part.

I use overdriventool 0.2.1. I've disabled all power states except for 7. I'm running 1550Mhz with 1000mv as my p7 for core and memory is at 1040 with 975.

Well some PSUs actually bench (loosely termed) higher. My previous 800W tested up to 940W with reasonable efficiency. So it is possible for a PSU to run higher than listed as well as not so well even within rated spec.
