The RX Vega 64 Owners Thread

HBM state 3 voltage is set to 1075mV. VDDC generally shows 1.0500V but the peak is 1.0875V. Clockspeed hovers around 1630-1650MHz.

Thanks for confirming that's a sweet spot there, that's generally what my daily2 clockspeed setting is too, I just run lower voltage and a held 1610-1620mhz as the reference cooler isn't terrible, but not great :)

3440 x 1440p users .. what kind of fps are you getting in games (throw examples at me!) and what settings do you use to get these? Can you get away with high / ultra or have to tone back?

Rough averages for my Vega 64 in balanced mode and High settings:

SIEGE - 120 FPS
GTA 5 - 90 FPS
Star Wars Battlefront II - 80 FPS

I think the performance is adequate for a 100hz ultrawide monitor.

Navi will be my next upgrade and hopefully it will be good for 144hz ultrawide gaming.
 
Okay, so I decided to undervolt just to see what happens (900Mv) and set the power limit to +50%. Been gaming for 3 hours with no problems.

I also noticed that even though it's undervolted it's drawing more power and getting warmer so I'm guessing that the drivers in their default state are not allowing the card to draw enough power which is what's causing the problem.

Why though? Does this sound like a purely software issue or could the card still be faulty? One day (in the very distant future) I'll want to sell the card on and can't be selling a faulty one.

Have you tried numerous games or just the same game you had the crashing experience?

Why mate? On 4K HDR gaming is faster even than the Titan Xp for heaven sake.
Nvidia has to drop prices not AMD.

I read a lot of your comments, and you talk more sense than most, and I enjoyed you posting your findings of the vega64 voltage tweaking.

But people still buy NVIDIA, even when AMD have the better product (looking at the 1060 v 580 etc) I know AMD can’t drop the price on vega too much as HBM is expensive, but in doing so I can see many people jumping ship to AMD, and even at a loss, that’s excellent PR for AMD.
 
Vega64 is a fantastic card, excellent build quality, IQ is better than Nvidia, is a 100fps 1440p card all day long, Freesync cheaper, power doesn’t have to be 250w.......but ppl are still totally blinkered by Nvidia, follow the sheep and hate on AMD etc. These Same people knock a hot AMD card yet fap over a hotter Nvidia card, same ppl that mock AMD high power requirement rave over an Nvidia card pulling more power, when AMD design a feature that isn’t beneficial today is pointless and stupid yet when Nvidia do it its forward progress. Just totally hypocritical on every front, that unfortunately is the Nvidiot mentality right there and why AMD are doomed even if they do make a fantastic card. The brand isn’t attractive like Nvidia, even though us guys that use them know just how good they are.

Point being, if AMD did make a fantastic card at a budget price, ppl would still fap over Nvidia and hate on AMD, brainwashing at its finest.

At £450, I enjoy gaming with it more than the 1080ti in my other rig.

You are correct but at $200 the HBM cost (so £200+ with VAT and exchange rate), they cannot cut without losing money.
Unfortunately AMD is not in position to lose money on selling products like Sony and MS going with their consoles but as @Ian Evey says, GDDR5X 11gbps (the memory used on the second generation GTX1080s, as first generation had 10gbps ram) is a good solution.

And AMD makes the same Vega with GDDR5 and DDR4 for heaven sake. -_-
Also they wont lose 10% fps. Because the GPU will run cooler. That tiny area where the core is now, is getting overheated by the HBM if look at the HWInfo.
The HBM runs way hotter than the core, raising temps as they are covered by the same piece of metal next to each other.

If AMD moved the ram to GDDR5/X around the card, the cooper block cooling the Vega 64 will run cooler allowing better clocks due to lower heat.
Why AMD hasn't done so, I have no idea. -_-

@LtMatt since you work at AMD.... maybe if you propose the idea above on the company ideas box, maybe you can get a promotion? :D

I posted on the other discussion this.... There were still excuses that the GTX1080Ti burns less power than Vega 64 but ignored the facts.

I had the GTX1080Ti Xtreme, could see how much power it used with factory overclock to 2021 (like all good 1080Tis like lightning, Xtreme, FTW etc) -_-

The sample card generally keeps to around 325W TDP but then, very occassionally, spikes to 353W and we report that peak figure here. Compared with other GTX 1080 Tis, on average, it has about 25W less power consumption when evaluated on a long-term basis.

I doubt anyone here has seen those power consumption values with their V64 if they didn't pushed them to the limits.
