Again, we're using The Witcher 3 at 4K for our worst-case scenario. This yields an average of Not bad. Conversely, pushing the card to its limit via overclocking gets us almost MHz and From the lowest to the highest average clock rate, we observe an increase of However, gaming performance goes up by just That's not great scaling, but it's not terrible either.
What's more important is the power consumption accompanying those numbers. Unfortunately, this is where the data gets ugly. Compared to the stock settings, just Going back to a worst-case scenario, the overclocked card averages Trading The efficiency curve drops off rapidly with increasing clock rates and the additional power those frequencies necessitate. Almost double the power consumption for one-fifth more gaming performance is what we'd call catastrophic.
The point at which the distance between both curves is at its greatest represents the so-called sweet spot. This is where the card operates at peak efficiency, right before it starts going the other direction. The temperatures are very similar across all six power profiles.
This is due to the fan's aggressive controller, which responds quickly when power consumption increases. For each of the two BIOSes, we provide thermal images for all three driver-based profile settings. As mentioned, though, all of the temperatures are fairly similar until we get to the overclocked configuration.Menu Menu. Search Everywhere Threads This forum This thread.

May 11, 18, I have undervolted my rx 8 GB since the beginning that i bought it and now with the performance overlay i was keeping track of the power consumption while playing prey Radeon chill is off. This is with vsync on at 60Hz while playing prey Constant 60Hz with the exception at the beginning of the level while loading. Only texture at medium. The rest at high.

I am going to reduce the voltage for the highest states by another 20mV and do a few test runs and repeat lowering the voltages.
Maybe i can get it down to 1.Forums New posts Search forums. New posts What's new Latest activity New profile posts. Members Current visitors New profile posts Search profile posts. Log in Register. Search titles only. Search Advanced search…. New posts.
whats the best setup for vega 56
Johnny05 said:. Joined May 22, Messages 12 0. It's a great card IMO but very hard to cool it with stock. P7 at factory is at mV. P6 at mV P5 at mV. I'm still tinkering when I get the time which is not much Last edited: Nov 14, Joined Oct 20, Messages 0.Menu Menu.

Sep 13, 4, Agreed with hearing that about the gigabyte card. I would honestly only recommend sapphire, asus or powercolor for the most part.
They have great custom coolers. Paratus Lifer. Jun 4, 13, 6, Justinbaileyman said:. So is Vega 64 the card to get right now?Forums New posts Search forums.

RX Vega 56 Tuning for Efficiency
Caused by my 3D device aparently Last edited: Nov 23, Joined Mar 18, Messages 5, 1. Pretty good work. Very true xkm Had a Rx before and it was a lot easier to tinker with. This way, however, RTG found a way to maximize performance in most use cases, something good for most people. Joined Dec 27, Messages 0.That said, the price also increases in unnecessary ways for the likes of Vega 56, which has one of the most overkill VRMs a card of its ilk possibly could -- especially given the native current and power constraints enforced by BIOS.
That said, we're working on power tables mods to bypass these constraints, despite the alleged Secure Boot compliance by AMD. We posted a tear-down of the card earlier today, though it is much the same as the Vega: Frontier Edition -- and by "much the same," we mean "exactly the same. And related to this, we also decided to livestream overclocking and undervolting on Press beta6a drivers, demonstrating the following final results:.
Pretty damn good, could be better if you spent more time than we did. This is W over stock, but with a higher clock-rate by roughly MHz, depending on which numbers you take. Keep in mind that clock reporting tools are questionable right now, so we're not sure how accurate they are.
Huge note : We have to validate these numbers in gaming.
For now, we only stability tested in FireStrike for a few minutes -- so not final, and not conclusive. But this does give you an early look at performance, with all the pains and driver bugs along the way.
The archive is below:. Steve started GamersNexus back when it was just a cool name, and now it's grown into an expansive website with an overwhelming amount of features. He recalls his first difficult decision with GN's direction: "I didn't know whether or not I wanted 'Gamers' to have a possessive apostrophe -- I mean, grammatically it should, but I didn't like it in the name.
It was ugly. I also had people who were typing apostrophes into the address bar - sigh. It made sense to just leave it as 'Gamers.
Does Undervolting Improve Radeon RX Vega 64's Efficiency?

Dener de Paula PereiraSep 25, I've had about Vega cards.
One was a serious dud and couldn't undervolt to save its life. Thats probably why. GeniusPr0Sep 25, GlennBSep 25, Reports since Thus monitoring via HWInfo or other program and getting data outside of Wattman itself for what the card is doing.
Or what it's drawing I suppose ha ha, well hopefully that's resolved. And then whatever limits apply, some users get a even when downclocking the cards and others can go up to almost on voltage while also barely having to lower clock speeds at all though depending on Vega 56 or Vega 64, memory clocks and type the overall performance impact from actually lowering clock speeds isn't much or even noticeable at all until you drop it to more significant values though I believe this changes a bit with the Radeon VII although it's also using the more free states and scaling rather than the prior use of the P state same as Navi and likely later cards.
These do undervolt too and much the same so it's very possible to hit to mv though again it depends on the GPU as everyone will behave a bit different plus overclocks or underclocks and again it doesn't have to impact performance in any perceivable way or by a very small amount for the reduction in voltage and temps and overall resulting power draw. Would have been nice if the GPU's could have been 1.
With this I repeated almost the exact same procedure too, from a silly Mhz mv what it was boost it could never realistically hit down to Mhz at mv and complete stability after eight hours of testing and performance only hitting a mild drop for the gains in junction and core temp plus memory up from to Mhz which isn't much but the cards are sensitive and early drivers could be prone to errors or other issues so keeping it here for now.
Memory might show crashes or artifacts or just a performance drop or stop scaling so it needs careful testing, core clocks and boost still hit around 2Ghz by default and this keeps it within a similar range just a tad lower thus the performance is fairly similar though the card has bit more reach than the Vega for overclocking a bit further if users would want to.
Well it can but I'd say the stock settings were kinda pushing it already for this card and what it positions itself as, Nitro and the Devil might be a tad more flexible but settings and overall limits are still what they are. EDIT: Well memory sensitivity goes for Vega too and HBM2 but it mostly showed graphical glitches or corruption as long as smaller increases and testing and re-testing were done before it got crash happy and it also showed gains in performance due to Vega at least until Vega20 and VII improved the situation a bit due to bottlenecking but due to Hynix and Samsung types it could differ a bit what was achievable plus 56 voltage and 64 at a slightly higher memory voltage.
Still capped though despite Wattman saying memory voltage but it operating as a different parameter entirely for some earlier P state and possibly overall voltage minimum or voltage floor not memory but for GPU core. So yeah regardless AMD is still kinda pushing the settings and voltge but it does allow every GPU to hit parameter specs and at least it's easy and flexible enough to be lowered down a notch and might not affect performance at all but sheering off in the hundreds feels a bit funny but eh it's a thing and it's pretty useful if the card is showing no issues with a nice reduction here plus lowering temps and power draw and improving core temps at least a little bit.
