The RX Vega 64 Owners Thread

Panos, quick question, do your settings work ok on the Reference Water Cooled Vega 64?

Why not give them a try? The power consumption is well bellow 300W. Maybe if you find it unstable raise power limit to 30-40-50%.

also lower the clocks slightly by 20mhz each if you feel is not stable.

Here are Lokken's settings at 1550s also.

Try first HBM overclocking not core. If your card doesn't push 1.3v to the HBM might struggle to clock over 1000-1030. But give it a try until it crashes, then reduce by 10mhz.
After that when you have stable HBM ram, try the core clocks.

would a superflower 650w psu be able to comfortably run an rx vega64 or is it limited to a 56?

some of these current deals have piqued my interest. currently on a 380x and freesync monitor - given we're not likely to see anything new from AMD for the foreseeable future I may well take the jump to vega.

I've been eyeing up a vega64 when my gtx970 isn't giving me what I need, but I'm not sure it will work in my rig with my 650w psu, SSD,, 4 hard drives, etc
Although it's a new psu, it's a good quality Focus+ gold

I'm STILL on the fence about upgrading my 290 to a Vega 64 but only have a 550W PSU (Superflower Golden Green). But I wonder if with some tweaking whether it would be workable...?

Nasher · 6 Sep 2018 at 09:15

A good 650 is enough.

AMD set the requirement high because people are using crap PSUs.

I had a Vega 64 LC running on a EVGA 650 Platinum just fine.

I have a 650 watt gold psu and it runs very well

Not all Vega's will be okay with a 650 watt PSU, As I did you might find it runs okay but any attempt at overclocking will cause a crash, I had/have an EVGA G2 650w Gold rated psu which I ran with the Fury pro, 1060 & 1080 with no issues, With Vega it ran okay but it couldn't run it with any sort of overclock including the turbo setting in Wattman and all that does is increase the power limit. You'll probably be okay just be aware that you may not, You'll just have to try it and see, fingers crossed,

ah ok, in that case i'll maybe just hold off. i've no inclination to change the psu so would rather not run the risk of buying and finding out it doesn't cut the mustard. do you know are the 56's lower power draw?

zophiel · 6 Sep 2018 at 12:28

i have a vega 56 in the kids pc on a 550w evga psu and that works fine, but cant overclock etc as above.

ShiWarrior · 6 Sep 2018 at 13:27

Thanks Nasher

I haven't had a 56 so can't tell you my experience with it but theoretically yes it'll use less power, All I can say is the price difference between the 56 & 64 would and did make me gravitate to the Vega 64 out of the two as it is the better deal, It's more likely than not that you'll be okay with a V64 so I wouldn't not get one, I was just letting you know my experience. I think that's why AMD have them marked them up as needing a 750watt minimum, some will need more power than others even if it is only as little as 0.1% of them, AMD are simply covering all the bases.

yea in fairness the 64 deals seem more appealing. i'll hold fire till i see what gibbo comes up with as i see he is trying to sort another ~450 deal and go from there. thanks for the info.

Panos · 6 Sep 2018 at 17:44

Gents, as long as you do not try to run your cards on Turbo mode (276W) or some custom overclocking without downvolting you should be fine.

Power Save mode needs only 176-180W an d the card will be running at 1400-1500 on air. Balanced mode is around 240s.
Also you can tweak the cards for higher clocks and less power at 240W-250W also. As long as you do not go full blast for 300W+ you should be OK with good 600-650W.
Assuming you do not have some intel overclocked monstrocity burning 200W on it;s own. (4790K, 7700K the upcoming 9900K).

Nasher · 6 Sep 2018 at 17:48

I got mine through today so I'll do some testing on my EVGA 650w.

Interesting because someone earlier in this thread told me my tx650m wouldn't be up a vega64 which has pushed me to consider a 1070ti or stick with what i have for now.

I'm running a ryzen 1600 running at 3.7 with a couple of SSDs so maybe a 64 is back in the running.

Nasher · 6 Sep 2018 at 17:56

Well I got it in and running already lol

Been running haven benchmark and no issues with my 6700k @ 4200mhz, 2x SSD, 1xHDD and Xonar sound card.

I undervolted it to 1050mv as well and so far seems stable. As I did on my rx480.
