The RX Vega 64 Owners Thread

[melmac]

As for challenging an opinion that's what forums thrive on so yes doing so is good as it leads to debates that are often interesting and informative, what isn't good is using what isn't a fact as one. I've never claimed what I said was a fact, I tend to point out that it's not but if you can show me where I've done that please do.

So you don't believe what you are saying is right?

The only way the C0's were usable was with water-cooling and the fact that they tried to sell the lesser chip in the flagship card is disgusting and I imagine they've burnt any trust they'd built up with the board partners, I just hope it isn't only Gigabyte who complained and got a new batch of chips.

This whole sentence is stated as fact. And none of it is true. None of it can be backed up with any kind of evidence at all. I can quote others if you like.

I wanted to find out what PSU's those of us here with Vega 64 and Vega 56 air blower cards are using?

I don't have one, but, a steam friend is using a 650w superflower golden green 80+ Gold PSU with Vega 64. If I buy a Vega 64, it's what I will be using too.

That was not the whole conversation though that was only one part of an on going series of posts between you, me and a couple of others where I had previously said things like " I think it's pretty obvious that" and "From that it seems that" Those are statements of an opinion not of a fact. I then continued with "It's not something someone like me could prove it's a presumption based on events we've watched unfolding over the last few months. " That's not me claiming it as a fact.

I don't have one, but, a steam friend is using a 650w superflower golden green 80+ Gold PSU with Vega 64. If I buy a Vega 64, it's what I will be using too.

I think I'm going to get a blower and test it with my 650 before buying a bigger one. It states a 750 watt requirement on the store page.

Should note I've see core wattage reach 320W+ quite easily using LC BIOS on my Air Card at stock LC Clocks. Assuming around 40-60W more for full card draw and you are pushing 400W actual quite quickly.

The core wattage in GPU-Z/HWINFO may not be "realistic", I have not checked yet. I say that from as in the past it has not been correct. As an example I had picked The Stilt's brains at one time concerning a question I had about OCP on Fiji. I knew OCP set in IR3567B was lower than amps shown used in HWINFO and OCP was not triggering. He verified that either driver was wrong or HWINFO. I then spoke to Martin Malik (author of HWINFO) and we concluded that something maybe off with driver, as HWINFO was showing what it showed to his app.

I think I might just grab a blower card, I'm now using the Corsair Air 240 MATX cube case and while the length and how many slots it uses are not an issue how high it is does matter. I've currently got a 650watt gold rated EVGA G2 psu and need to factor in how much more wattage I need.

Personally I'd have no qualms with using a EVGA SuperNOVA G2 650W for VEGA 64. Why I say that is the 650W is what it can output to the rig, so from the wall it could draw upto ~715W and not be an issue. As an example you can see in reviews like JonnyGuru where they loaded the V850 I have with ~850W and it pulls ~950W from wall. Next it has a single 12V 54.1A rail, so more than ample IMO. It also has 2 PCI-E cabling connectors so you can power each 8 pin PCI-E with it's own cable. I believe it is SuperFlower Leadex platform (nice low ripple/sound voltage regulation, etc).

 

[Bonjour]

I have a monitor plugged into the wall, and total system draw rarely exceeds 450W. No idea how much of that is GPU, though my Vega64 is undervolted to 1000/1050.

 

[gupsterg]

I've seen max 500W for complete rig from wall inc screen.

I don't get it, you had a 1080, why are you now going to buy a slower ref 64, and possibly a new PSU as well to go with it, thats going to be much more expensive

My new PC is an MATX build and the 1080 did not fit plus my monitor is a Freesync ultrawide.

I haven't convinced myself to get it yet but the price isn't bad at £455.

If the V64 is what you want, personally I'd go with OCuk Sapphire V64 LE with 2 games @ £489. Otherwise the V56 @ £390 with 2 games is better than V64 @ £455 IMO.

Currently I'm happy with my latest profile , as it has come very very close to the MSI GTX 1080 EK X, which boosted to ~1975MHz "out of the box" for most 3D loads.

DPM6: 1557MHz 1000mV
DPM7: 1652MHz 1100mV
HBM: 1100MHz 1050mV
PowerLimit: 65%

This has yielded slightly higher min FPS, very close average FPS and ~10% less max FPS in this bench vs GTX 1080 example.

Spoiler

This profile is now ~1615MHz for 3D loads and being tested for Compute.

On another note thoroughly enjoying being back on AMD driver panel vs nVidia. Games have FPS caps as required, globally it's not enabled, so I can bench without having to alter a 3rd party app as I did when on nVidia. So far Wattman is behaving and remembering settings, etc, etc.

Have to admit I agree, the AMD panel is much nicer to use. Only problem I had with my Fury is Wattman wasn't remembering my settings etc and was frustrating as hell.

 

[five8five]

Hardly. When you really think about it, 10 series have been on the market much longer than vega.. All afterboard partners need to do is reuse the same coolers... 1060 to 1080ti is the same. No wonder it's out faster/day one

No excuse from me though something is clearly up with Vega and AIB.. I think it's prices, cost to manufacture and the market GPU segment is bloody stupid atm

That's an exaggeration! PCB and cooler sizes vary greatly between 1060s and 1080Tis.
I do agree that it's easier to produce a 1070Ti using existing 1070 PCBs and coolers and some I believe are using 1080 PCBs and coolers.

There's something seriously amiss about the lack of custom 64s. How many months is it since release? It's unheard of really.
I've given up on the custom 64s. For one thing if they are ever released there's going to be very little choice.

Same here, I grabbed an RX470 off the MM while waiting for the 1080 to sell and I'm glad to be back with the AMD software rather than the Geforce experience.

From tests and results I've seen online the Vega 64 does a decent job overall and for my monitor which is 3440x1440 with a Freesync range of 30-75hz I'm sure it'll provide a better experience than a 1080 without any adaptive sync.

I never used WattMan on Fiji as did VBIOS mod. I'm gonna stick to WattMan and then bite Matt's ears if the blasted thing does not behave! .

One other thing I noted with my foray to GTX 1080 was it exhibited the same issue as Fiji, ie when monitor went to sleep it would come on at times without any input device interaction.

Most definitely. I hated gaming without variable refresh rate tech. Whatever few hair I had left on my scalp went due to that experience .

 

[Ree]

i am seriously tempted to get one of these to have freesync back, its just a shame about the crappy reference coolers. would my 750W G2 be enough to power it also?

 

[gupsterg]

Plenty IMO .

My latest V64 tweak setup vs last run of GTX 1080 (~1975MHz, stock GDDR5X) in 3DM FS.

Then latest V64 vs GTX 1080 on an older driver (it's best of 3 run vs VEGA) in 3DM FS.

Clobbers the GTX 1080 in GPU only tests, even with vast clock difference. CPU only is decent enough, I believe combined test is showing AMD driver overhead is having an affect .

cheers bud, got some thinking to do.

NP .

The EVGA SuperNOVA G2 750W is a stonking PSU. It was on my wishlist when I purchased a couple of PSUs back in 2015. The only reason why I went V850 in main rig was at the time it was costing £85 on a ridiculous promo. Otherwise I had a Seasonic 650W in my main rig for ~10yrs in my main rig. I'm not a low hour user either. I have at times done +70hrs of TR of testing in one go, ~175hrs in the past with other CPU/GPU combos.

Buying bigger PSU than you need helps in that if later you need it. But in reality a way bigger PSU than what the components need is inefficient. You can see this in reviews where they give decent data, like JonnyGuru/TPU.

I've probably only started to somewhat really use the V850 now with TR/VEGA, prior it had had GTX 1080 and before that Ryzen. And way back i5/Fiji/Hawaii.

What's your out of the box results for Vega? non tweaked p-states and stock hbm2 clock and stock 1.25v voltage, stock 0% limit, and stock fan speed.
What are your Gtx 1080 tweaked results ? = gddr5x overclocked and core 2050-2150 MHz and undervolted?

 

[gupsterg]

IMO out of box Vega performance was poor in what I tried. As is the ref cooler. The basis of this was my purchase price vs similar priced competitor product (not the EK X).

My experience on ref cooler lasted ~30min. The moment I did a SuperPosition 4K optimized preset run with monitoring, I was frankly distraught as much as I believe the silicon would have been . Example ref cooler was MAX GPU: 74C Hotspot: 105C HBM 81C, with WC same setup MAX GPU 36C HotSpot: 55C HBM: 41C.

What we see in WattMan when we move to manual voltage is not what the silicon uses in normal operation, regardless of stock/tweaked. Vega uses AVFS, Advanced Voltage Frequency Scaling. I believe this is an evolution of Adaptive Clocking as done on Streamroller, link. AVFS AFAIK came about with Carrizo, link. Then we have ACG, link, which again has similarities to AC/AVFS.

At stock say when running f@h my VEGA was getting to ~1650-1700MHz with max 1.131V in HWINFO. Once I tweaked DPM 7 to 1100mV it become the ceiling voltage. Even if I currently use DPM 7 as 1652MHz, in Compute tasks GPU MHz can be above that. I believe this is all due to the "tech" employed. HBM voltage in WattMan is not HBM voltage, that is for sure. V56 is 1.25V and V64 1.35V. When viewing the voltages associated with HBM clock states it is as if it is linked to GPU voltage/DPMs somewhat. This was the case on Hawaii for example, you had same number of DPM states as GPU in RAM Freq table and both tables had to match for VID, manual or EVV (Electronic Variable Voltage).

The GTX 1080 I didn't spend time tweaking TBH. I have some results IIRC of 2.0GHz+, will have to check. GDDR5X from what I had read from owners shares on OCN (where I practically live ), doesn't OC much, so I never tried it. My card didn't like undervolting at all when I tried it, as it was boosting to ~1975MHz due to low temps (as on WC), how nvidia boost 3.0 works and the MSI EK X has increased powerlimit compared with other Pascal cards. See the FE bios PL vs EK X.

I believe nVidia boost 3.0 is very polished vs VEGA boost. VEGA clock/voltage tech is vastly different then any past AMD GPU I have had my hands on. Example Hawaii was ever so slight changes vs Evergreen. Fiji again was mild changes vs Hawaii in this context. I do like how VEGA is this context vs past AMD GPU, it just takes some getting used to IMO.
