AMD once again violating power specifications? (AMD RX-480)

I don't think the join date really means anything -- a lot of people join forums when they have a problem that they need help working through. I don't even remember some of the forums that I've made accounts on in order to troubleshoot some issue. Whether or not the posts or trolls or not is still hard to tell, but the main thread in that post is at the very least believable -- a 970 board with an overclocked 480 (if at stock it's pulling a bit over spec, overclocked is probably ridiculously over spec). 

Yeah that's what makes me on the fence on it. Though at the same time you have people like that johnathon.link guy who seemingly made an account just to say = 

"AMD RX 480 violou o padrão PCI Express (so what!) - YouTube    here is the video that shows where AMD violated PCI EXPRESS !"

 

It's just the tone of voice which sounds trollish in nature but yeah, by all means this could be legitimate. Main post is pretty believable too, but yeah I'm not one to believe stuff like this without any actual evidence.

Some don't seem to understand how serious this problem is, so I explain it with pictures.  BTW, I'm no artist, so this is the most artistic thing you'll get from me.

That was beautiful but you messed up, bro. That's the 'me gusta' face, not the 'no me gusta' face.

Have had an 83w from the board OC'd 480 running since yesterday on a benchmark and guess what, the system still runs fine.

 no me gusta don't seem to give the expression, I was looking for.

I smell a possible recall.  I bet and is going to recall all these cards and replace them with cards that have a 8 pin power connector like they should have done in the first place

Did you raise the power target? Tests show that you don't gain any performance from OC'ing because it's power starved meaning it doesn't really hit the specified clocks but raising that target blows up the power consumption. Also, you should also try undervolting a bit. Improves temps and could give you a better OC despite it being somewhat counterintuitive. 

1.075V stable was achieved by someone. It actually kinda points to that the card is running at too high a voltage at stock. Too high as in more than necessary, not too high as in explosions everywhere.

Maybe for you, but there's another topic that says that this card has already killed a few peoples pcie slots.  I would immediately disable that over clock if I were you unless you want dead pcie slots on your motherboard

no, leave him to his own devices

if it pops he'll learn the hard way

I literally have 100's of 1155/1150/1551 mobos/cpus at my disposal so it's not a worry and with not 5 480s in my shop, I might go crazy and see if I can break something because I'm having a feeling people are breaking them on purpose to try and get some $$$

Well since I own 6 computer stores, I think it's safe to say I know a thing or two about computers..

dude, if you have a spare mobo to test this on, you should totally do this to see if it is possible to kill the mobo's pcie slots in this manner and make a video on it.  then once the mobo is screwed up, send it off to photonicinductions to see what happens when you input not 12 volts into the 24 pin connector, but 100000 volts.  i would love to see what would happen

Are we still arguing over whether it pulls too much power, and/or if that is really a problem or not?

Well.. I'm going into my 6th year being the sole owner of the shops. And for the first 4 of those years I put in near 60 hours a week  I have also been working in these shops since I was 13 due to the fact my oldest brother opened them in 1990 and made me work (slave labor sometimes)

No, we've moved on to dicks apparently.

I'm still waiting for that AMD statement they're preparing since yesterday

guess their lawyers are in berserk mode

That's my plan for the rest of the day actually. The video thing sounds good since I've been wanting to get past the 20k youtube sub mark but that requires me driving 45 minutes home to get my 70D

As long as we're changing the subject, I guess now is as good a time as any to point out that we've hit 32 pages and Hitler hasn't been mentioned once. So much for godfrieds law.

 

 

 

Edit: Shit! What have I done

[Briggsy]

This is sorta old now but I didn't see it linked, and its an interesting (and funny) conversation about 480 power consumption.

I'd forgotten to but I just did.  It's nice to see the board wasn't destroyed but it's still troubling to hear that it happened.  I'd be curious how Intel boards handle this problem.  In that video with that TwoCents guy and the other guy discussing this they'd said as a result of some cheaply made (MSI I believe it was) motherboard being used to even slightly OC a CPU it actually destroyed the motherboard for some people I believe it said.  (It was late, I was tired so I'd have to rewatch that video to double check that.)  So if I'm remembering the video right then it suggests it's possible to not simply have a shutdown but rather actual damage to a motherboard from a power related problem.

 

The Science Studio did claim that the issue with the 480 might be solved by adjusting the configuration/number of PSU connector pins so if a fix really could be that simple there may be reason to hope that non-reference 480s with sufficient PSU connector pins may not have this motherboard issue.  Assuming I'm understanding all this correctly.

 

The Krait 970 board from MSI had a very under built VRM (voltage regulator module).  FX CPUs really like power.  So since you have to overclock the FX CPUS to get them to even start competing with Intel CPUs (single core performance), I think more than one of those boards burned up... literally...

 

If you have not seen this, it will be interesting to say the least:

it's uncertain

 

from what reviewers say regarding their overbuilt test benches is that the power traces for the PEG are directly connected to the 24pin ATX power connector and have no other components on them

 

it's possible that some older mobos were built with over current / over power safety circuitry and aren't direct traces to the ATX connector

In Reference to your earlier comment about the AM2 board with 480 vs 970? shutting down.

 

At what point does the system shut down with the 480? IS it during stress or on boot? It is likely ripple or a confluence of iffy mobo VRM and 480 overdraw on the PSU rail rather than any damage or issue internal to the motherboard. The power phase fiasco of years past may be a major hurdle for this card if people are really trying to push it on that older hardware.
