AMD RX 480 Fails PCI-E Specification

The Running Man said:
But y'all AMD fans said there was no problem?

Guess there was:/ But its okay you can downclock your card for no extra cost!

thats your own assertion, to take a rare comment or a minor opinion and make it the norm, nobody or very few ppl would have denied the issue of the card going out of spec on the pci-e, what ppl denied is the danger of the card being able to destroy motherboards.
anyhow latest AMD statement said just that, that the card can sometimes go over spec, but that still wouldn't damage PC components, and that the fix will be up tomorrow.

PCPer shows that the 960 is not a problem. Go read the article again:
http://www.pcper.com/reviews/Graphi...s-Radeon-RX-480/Evaluating-ASUS-GTX-960-Strix
At stock clock speeds under Metro: Last Light at 4K, the total power draw on the GTX 960 Strix card never exceeds 110 watts, motherboard supplied power never exceeds 30 watts and the 6-pin PCI Express power cable never exceeds 80 watts.

I decided it crank things up slightly by adding in the maximum voltage increase to the card through Precision X software and then setting the GPU clock offset to +93 MHz. The resulting total power increases to over 115 watts, while the motherboard power increases to nearly 35 watts

Jay2Cents is an AMD fanboy who is a couple short of a 6-pack and is merely quoting another AMD fanboy without a shred of evidence.

WattMann?! Him an AMD fanboy?

He likes NVIDIA so much he's still got 3 GTX 1080's despite only 2-way SLI being supported officially.

Hey, gotta call him something when you don't like the guy but all common vulgar insults are banned from the forum.

Fanboy is the nerds choice in such times.
 
Youtubers should not be looked to for knowledge or wisdom. People too lazy to read are their audience.

Saying that I did enjoy RTU's video on powergate.

thankful it is getting fixed later as i would have hated to return it :)

im guessing the fix will just limit the power to the pci-e slot and shunt the main load over to the 8 pin thats in disguise of a 6 pin? (read that somewhere one of the pins isn't a sensor but drawing power)

im one happy drunk bunny as soon as i get that driver :)

If redistributing the power from PCI-E Slot to the Connector doesn't affect performance, which it shouldn't (happy to be corrected), then that's fine by me. Without the power issue it's a great card for the cost & I would be 100% happy with it. So hopefully, problem solved, and hopefully AMD will have learned a lesson from this and next time they won't be clever & just stick a darn 8 pin connector on it.

Assuming the total power draw remains the same and thus power throttling remains the same, it should have no effect on performance.

It will put the power draw on the 6 pin PCI-E power cable even further over spec, but there's no indication that would be a problem. As far as I know, they're always rated for well over spec.

Does anyone know if a non-reference card with an 8-pin connector would solve the problem? It has the potential to do so but it would still depend on how the power supply was divided and I don't know if a 3rd party card maker can change that. AMD's statement seems to indicate that it's determined by the driver. If it's set to a 50/50 split (as it is on the reference cards with the current driver) then a 8-pin connector won't help.

Fair point, but I highly doubt he actually paid for any of those 1080's.

I dont think he is biased to amd or nvidia but he is biased to both vs the consumer if that makes sense, he doesnt seem to go against what their marketing teams would want reviewers to say and he even made a video claiming the binning of chips has no affect on achievable speeds.

I be surprised if he has paid for any of his gpu's.
 
Has there been any confirmed motherboards being killed by this ? Iv read the PCIE 3.0 spec and it does indicate that PCIE GFX slots have the ability (if made in such a way) to provide over the 75watts.

Also those twitch clips of the guy looking at volt modding the card where cool but lack some key electronic information. When he says "see there is some multi kilo ohm resistance, these are not connected" what that really means is its either not connected or there is some high resistance electronics between the two test points. The only real way AMD could "redistribute" power from PCIE slot to 6pin would be for there to be some switching components on the board itself

Only one person has claimed that it's damaged his motherboard. Although his system was very old, and in a terrible state.

Isn't this what the Auxiliary pci-e power connector that you get on all sli/crossfire boards is for? To cover instances where more than the standard 75w is called upon. Even though I only usually use single cards, I still connect the molex or sata cable to provide the extra power for extra stability.
