I've been running the 480 at stock volts and undervolt on a 990FX board which all of them have only PCI 2.0 slots, without the 4 pin molexs jumper to the PCI slots, and have yet to run into a problem.<br><br>
Just because some jackwad who obviously had and old an never maintained build with a crap PSU and OCed his CPU and GPU is not enough to make me go into insane mode.<br><br>
If someone doesn't know wth they're doing and doesn't maintain their equipment properly is no problem of mine. The 480 didn't fry his board, <b>he</b> fried his board. The recent miner frying his board... it's a <b>miner</b>, running your equipment 24/7 at max for 3 years <b>will</b> degrade your equipment. I've blown boards, GPUs, and CPUs BOINCing 24/7. Again, I am <b>not</b> concerned.<br><br>
Stop being ridiculous, because that's exactly what all of you are being.</div>
</div>
<br>
Just because your system is not fried yet, it doesn't mean anything.<br><br>
Not every damage occurs instant. There is always the <b>damage over time</b> possibility. Most of the defects happen after longer periods of stress. Reports of defects on the internet say they had the crashes or burn downs after several hours of intense gaming. In short we need longterm stress tests and more experience with this card and behavior.<br><br>
Although we need to take a whitelist for what hardware worked and which may have been compromised. Everything else is unprofessional.

Fine, I'll do a burn-in tonight at <b>stock</b> voltage to prove you wrong. This whole entire shenanigans is just dumb, but if it makes <b>you</b> feel better, I'll do it.<br><br>

Please don't be miffed about this!<br>
As I said, the damage can occur slowly. It has not to be visible immediatly. This is why the issue is so problematic. You can think you are not fine, but at the same time your mainboard / components get worn out faster than usual.<br><br>
Don't blame me for what is going on.

I think he's blaming you exclusively for fear mongering.<br><br>
By the time any degradation occurs we're all going to upgrade anyway, we're talking shy of a decade of daily use here, and even then that is conservative.<br><br>
And before you even answer with inmensurable data I'll even quote what you said<br><div class="quote-container" data-huddler-embed="/t/1604477/reddit-rx-480-fails-pci-e-specification/710#post_25314650" data-huddler-embed-placeholder="false"><span>Quote:</span>

I trust my instinct and the amount of scientific knowledge that is actually measurable.</div>
</div>
<br>
So with your answer I'd like to see how measurable the data backing up your claim is because I have a feeling there's 99% bias, instinct and anecdotal evidence with it.

<p>While you are almost saying people are making this up due to your experience how would you know? You have a world class Motherboard with good components from what we understand. No one is saying your situation would bring about disaster.</p>

Guys, common. Both Nvidia and AMD mess things up here and there. Neither company is a bunch of saints.<br><br>
I can tell you how I feel as a potential buyer with no particular inclination to go neither red nor green. I am on a market for a graphics card. I don't want to spend over $300. Buying a 2 year old 970 for ~$260 doesn't seem like a very good idea cause it's an aging piece of tech. Plus, 3.5Gb thing kinda bothers me.<br><br>
I was looking forward to this release and was really close to pulling the trigger on 8GB XFX card with that sweet looking backplate... But then decided to hold off to see what aftermarket 480s as well as 1060 will bring to the table. And kind of happy I did. All the reports that RX 480 pulls too much power from the pci-e slot are alarming. It's not even about users who's pci-e slots melted and stopped working but the credible (IMO) reviewers, such as PCPer, that made me think twice before buying a reference card. It doesn't seem reasonable to dismiss these reports as Nvidia conspiracy and bunch of smoke. I mean, the true scale of this issue, whether it's significant or not, will appear very soon. Why do people keep insulting each other over this?

So much for measurable scientific data right here.</div>
</div>
<br>
Does it matter ? We can show you all the proofs you mon't recognize 'em.<br>
Facts are plain simple, AMD did not respected PCIe specs with their RX480 Vanilla and by a big margin. Period.<br>
How is it possible ? It's another question...

Oh... one day ASUS components and mobos are crap, the next they're top notch.<br><br>
Either way, it's still PCI 2.0 and rated for less then PCI 3.0 which is most modern Intel boards and has 90%+ consumer marketshare these days.<br><br>
Which ever way you try to play this, it's still going all hulk mode on what is a non-issue anyways.

Some dude on the bitcoin forums claimed that his motherboard was fried from running 3x RX 480s (under-clocked his cards)....<br><br>
well...<br><br>
Take 6x R9 290xs each pulling 66W from the 12v rail and around 9W from the 3.3v rail of their respective motherboard PCIe slot. Do the math...<br><br>
That is 450W being pulled from the motherboard (I ran that on several machines during the bitcoin heyday and many other users run similar configurations on cheap motherboards).<br><br>
This user wants us to believe is that 3x RX 480s pulling 80W each from their respective PCIe Slots are somehow responsible for burning out the motherboards 24-pin connector.<br><br>
Lets do the math.. 3x 80W = 240W.<br><br>
So let me ask you all... how come many bitcoin miners can run 6 R9 290xs on the same motherboard using PCIe ribbon cables pulling 450W without a single issue yet 3 RX 480s are somehow responsible for burning out a motherboard after pulling 240W?<br><br>
What is a larger number. 240 or 450???

There's a lot of misinformation on this thread.<br><br>

They aren't 2.2A each, they are 1.1A ... just as PCPer said.<br><br>
.</div>
</div>
<br>
Yup , Completely missed the " two adjacent pins powered " on the data sheet , so 1.1A<br><br>
Never mind .

The spikes are normal. When you turn a circuit on... it will spike for a a very very very short time (usually measured in microseconds). It is the same thing that happens when you flick the switch to turn on a light bulb. All circuits operate this way. What you want to do is filter those out in order to get a better idea of the true sustained load. In doing so (as PCPer did) you get the proper results.<br><br>
You are new to this stuff eh?<br><br>
On another note... if you think you can come here on overclock.net and spout nonsense to a very knowledgeable user base... then you are wrong. My suggestion to you Mr Dragon is to fly on over to wccftech and breath your fire over in their ever-so knowledgeable comment section. I am sure that the ensuing flame wars there will be more to your liking.

Well GTX 970 has TDP of 145W and it goes way way over!<br>
So basically you are saying that GTX 970 and GTX 1070 should never use over 110W.<br><br>
RX 480 8GB with downvolts will use less then 120W.<br><br>
In this case XFX RX 480W peaks at 125W stock.<br><br>
XFX 480 8GB claims 120W TDP<br>
<a href="https://www.techpowerup.com/gpudb/b3684/xfx-rx-480-black-edition" target="_blank">https://www.techpowerup.com/gpudb/b3684/xfx-rx-480-black-edition</a></div>
</div>
<br>
The TDP on the reference RX 480 cards is configured to 110W. That applies on the calculated (by PM) power draw of the GPU, not the measured one. The controller on RX 480 supports DCR measurements, so technically the input power could be measured more accurately. At the moment GPU-Z is not displaying the data from the controller directly (you can see the controller data on 290/390 cards for example).<br><br>
The values displayed for nVidia cards are based on shunt measurements (AFAIK) so they include the VRM losses (as the shunts are for 12V inputs).

That is 450W being pulled from the motherboard (I ran that on several machines during the bitcoin heyday and many other users run similar configurations on cheap motherboards).<br><br>
This user wants us to believe is that 3x RX 480s pulling 80W each from their respective PCIe Slots are somehow responsible for burning out the motherboards 24-pin connector.<br><br>
Lets do the math.. 3x 80W = 240W.<br><br>
So let me ask you all... how come many bitcoin miners can run 6 R9 290xs on the same motherboard using PCIe ribbon cables pulling 450W without a single issue yet 3 RX 480s are somehow responsible for burning out a motherboard after pulling 240W?<br><br>
What is a larger number. 240 or 450???</div>

Hawaii or Fiji based cards don't draw anywhere near the maximum allowed by the specification (i.e 66W) from the PCI-E slot. They draw the power for the GPU VRM from the PCI-E power connectors and the power drawn from the PCI-E bus itself only feeds VDDCI VRM and the display interfaces (on Hawaii) and MVDDC and display interfaces on Fiji.

Aha,<br><br><a data-huddler-embed="href" href="/u/348110/The-Stilt">@The Stilt</a> has arrived. There's a man's opinion that I can trust.<br><br>
Which... btdubs... got any Polaris BIOS' yet? <img alt="biggrin.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/biggrin.gif">

Oh really now... then how does a MSI R9 390x Gaming 8g card get to pull an average of 344W then? Remember.. the card has a 8 pin and a 6 pin connector. That means 150W and 75W for 225W.<br><div class="quote-container"><span>Quote:</span>
<div class="quote-block">For this test, we measure the power consumption of only the graphics card via the PCI-Express power connector(s) and PCI-Express bus slot. A Keithley Integra 2700 digital multimeter with 6.5-digit resolution is used for all measurements. Again, the values here only reflect the card's power consumption as measured at its DC inputs, not that of the whole system.</div>

Are you going to tell me that it is over PCIe power connector spec?<br><a class="H-lightbox-open" href="http://www.overclock.net/content/type/61/id/2820107/"><img alt="" class="lightbox-enabled" data-id="2820107" data-type="61" src="http://www.overclock.net/content/type/61/id/2820107/width/350/height/700/flags/LL" style="; width: 228px; height: 700px"></a><br><a class="H-lightbox-open" href="http://www.overclock.net/content/type/61/id/2820108/"><img alt="" class="lightbox-enabled" data-id="2820108" data-type="61" src="http://www.overclock.net/content/type/61/id/2820108/width/350/height/700/flags/LL" style="; width: 228px; height: 700px"></a><br><br>
Therefore I have to ask... where did you get your information from?

Anyway, based on buildzoid's video the GPU VRM power input is infact split between the PCI-E slot and PCI-E power connector (and not just shorted), like I expected. w1zzard from TPU promised to make me some measurements to find out the exact structure of the card. If the power source for the GPU VRM phases are split 50/50 between PCI-E slot and the PCI-E power connector, I should be able to remedy the excess power draw from the slot quite easily. The fix could be applied either by Afterburner or by using a modified bios (once flash tools are available). The fix doesn't affect the total power draw of the card or the performance.
