The RX Vega 64 Owners Thread

[TonyTurbo78]

Note that a lot of people putting settings up in this thread are running their vega as part of a water loop set up so be wary of just copying their settings. I'm running a Vega 64 Red Devil and these settings give me a decent balance of performance, temps and noise. I can go higher with the clocks but this is a good balance for running 3440x1440.

Spoiler

Blimey mate, just seen this. You running 1175mv on an air cooled card plus a +50PL? Wowsers, that goes against all train of thought trying to not go above 1100mv to keep the card cool without having it sound like a 747.

That Red Devil must have excellent cooling and fans, brilliant mate.

It does do a good job but I had to give it some help via a pair of 14cm fans on the case window pushing air directly on to the card, https://www.overclockers.co.uk/cors...wer-gaming-case-gunmetal-black-ca-068-cs.html

I know it's only a small undervolt so I may see if I can drop it a little more this weekend, I've just finished testing the above settings with the HBM at 1040 and it appears to be completely stable as I've been doing long sessions with Strange Brigade and Shadow of the Tomb Raider, Do you think I should drop the power limit then?

I’m sure you’ve done hours of testing so you’re probably in a better position to know the answer to that than me. All our cards are different, they all react differently depending on temps so I’d say if it’s working good and you’re happy then leave it.

If you’re bored or wanna tweak though, you could run an overlay when running fire strike in windowed, run the demo looped whilst clearly showing clock speed and voltages. Note the clock peak and wattage used, then maybe drop the p6 and p7 voltage to 1075 and 1100 (leaving frequency) respectively whilst keeping the +50PL. If you get similar peak clock frequency and it’s stable, you’ll undoubtably be running cooler and probably be only using about 250w. At the moment you must be busting well past 320w.

But you’ve probably tried all this Anyway so if it’s running great which it sounds like it is, leave it and enjoy gaming

Picked up a Red Devil today and have been playing with the Wattman settings. Do the profiles not stay on every time you boot up?

Pretty new at this so far, but I have currently: 50% PL | P6 - 1582mhz/1075 | P7 - 1677mhz/1100 | Mem 1075mhz/1000 (frequency for core clock set at 3% results in ~1630mhz)

I have tried the Mem at 1100mhz/1040 but it crashes. Is it now worth me fiddling with the Mem and trying to squeeze more out and then focusing back on core settings or should I now focus on tweaking down the core settings at the current Mem settings?

Reset core.
Use HWInfo and see if the HBM voltage is 1.35v. Is not you cannot get it to 1100.

Tomorrow going to try Sapphire Strix for overclocking. Saw some interesting things there, like +200mv and a slider setting 2800 core

(hahhahaha)

I've downloaded HWinfo and It's showing 1.356v, does that mean im at the limit for mine?

I just tried default clock settings with mem set at 1100mhz/1050mv and this seemed to pass some tests without crashing. I assume now I need to work on the clock to find a good balance?

The HBM is locked @ 1.356v, the voltage settings in watt-man are not for HBM despite the naming, so you might as well set them all to the same value to be honest,

one thing i have noticed on my card is the voltage figures seem to be power bands as well i.e

1000-1050 = 200 watts mode
1060-1100 = 220 watts mode
1110-1150 = 270 watts mode
1160-1200 = over 300 watts mode

the actual watts will jump about under load, the above is just a rough guide and thats with 50% power target

so say you have your card at 1040 on all P states you might as well put 1050

Thanks, now set them at the same value and getting some respectable figures. Under gaming load the temps sit at ~60c for GPU and ~62c for Mem, 1617mhz core clock & 1100mhz memory with 260W max usage.

You should be fine then.
Did you tried those settings here and didn't work?

Use HWInfo and look at HBM temps btw. If you see them going +25C over the core, and I know sounds extreme, maybe replace the thermal paste with Thermal Grizzly Conductonaut?

Btw saw someone going close to Firestrike graphics score 29000 (6700K @ 4.9Ghz) with an undervolted Vega 64 which was at sub 330W power consumption.
As soon as I get his settings, going to post them here.

He's probably just got extremely good cooling vega likes that.

Doubt that's it, my cooling is pretty darn good ... at some point though pushing the clocks any further just doesn't give more performance. It would seem to be a power limitation that may only be overcome (perhaps) with a custom BIOS, and as I'm on a Red Devil there aren't even any available for my card.

Pushing 29k that’s maybe 1500 points higher than I thought was the absolute maximum achievable on this card. If you get 26k graphics score you’ve a cracking Vega score, 27k and you’ve hit the Vega jackpot (which you and I are very close to), but 29k I need to see it to believe it. Gotta be LN2 or something else a little naughty going on. I’d hazard a guess you’d need north of 1800mhz on the core and 1250mhz on the HBM to get anywhere near 29k surely Panos. Vega hasn’t got that in her, I need to be proven wrong though. That would be insane if true. Where did you see this?

Maybe. My reference air 64 wont use anywhere near as much power as say the liquid one. I'm pretty sure it would perform much better with higher clock speeds if I flashed that bios onto it but I've also noticed the clock speeds can take dips even at fairly low temperatures. The cooler you can get it the better.

Sorry deleted post..

29k that’s 2k higher than I thought was the absolute maximum achievable on this card. If you get 26k graphics score you’ve a cracking Vega score, 27k and you’ve hit the Vega jackpot. But 29k I need to see it to believe it. Gotta be LN2 or something.

Actually is just an LC. So in par to the Nitro & Red Devil more or less, and I am on custom water so probably can achieve it.
One thing I know is running 1760 constantly at 1080mv with +50% PL and P6 1682 @1000mv.
But he is using OverdriveNT for P3-P6 also. However I do not know the exact settings, which matter here to support the overclock and not crash out.

What was the graphic score ?

28811 he said, but with just an 6700K. But I need to get his settings and confirm.

His reply was to someone else with different settings at 28092 with a Ryzen 1700.


@TonyTurbo78 mate we need to find some 7980Xs, delid them and OC to 4.9Ghz.
We can beat then Kaaps benchmarks

 

[majestynl]

28.092 for FS is a great score!

My best score before i changed the loop direction + thermal pads + Tim was: 26.866
https://www.3dmark.com/fs/16136764

Didnt play that much, need to find the the best setting for benching.

Just ran a heaven bench right now. Never runned heaven for benchmarking. Mostly just to test my settings. Dont know if the score is oke or not?



Vega 64 WC, LC bios with PP 150%

 

[TrixX]

@Panos - Yeah I can't reach that, anything over 1760 (set for P7) and it hard locks. Seems like mine just has a frequency cap where it won't function beyond it. Interested to see what the undervolt for the rest of the P states will do though...

Yeah. Mine gives up at 1717 somehow regardless the voltage and really good cooling (waterblock and liquid metal). But it could be a combination of all the P states together imho.
We shall see when I get the settings. Maybe try to flash the 1st BIOS to the LC one and try if everything else fails with the Nitro.

1200HBM!!!! Wow

However seems your core is throttling operating well bellow the 1700 mark. Have you considered to lower the voltage to 1150mv, 1714 core and 50% PL?
I bet with your CPU you will go over 27000 there.

Can you provide us with your soft table settings please to give them a try also?
