[Reddit] RX 480 fails PCI-E specification - Page 24

To put it in perspective for me personally. I was Octane Rendering at the time and had spent considerable time optimizing my content to stay under 4GB memory, 3.7GB to be exact leaving some fluff room. I bought (7) 970's for my ASUS WS motherboard useable with PCI-E Risers... Basically the "Surprise" wasted my time and purchase.

Thankfully I sold all but one of the cards to OCN members at huge discounts as I had slapped Waterblocks on them etc... 

So many don't trust the GPU makers apparently. biggrin.gif

I was on PC-tinkering hiatus when this happened so I only learned of it recently. I think you're an extreme example but nonetheless it would be frustrating. Some shoddy marketing for sure.

On topic:

Has there been any definitive information so far which suggests that the RX 480 does in fact have a problem with PCI-E power draw that could lead to major performance degradation or hardware damage?

I heard read they might be trying a new design with airflow holes in the pcb so downdraft coolers like this will get more airflow through the cards. I could be completely wrong though.

Truth is 980ti & T-X owners have had near the ballpark same level of performance we see now with the 1080 etc...for well over a year already, and looks to be 2 years by the time we see any "considerable" upgrade in performance.

Many of us want AMD to compete at all levels, and I know that's always arguable especially if AMD chooses not to.

If AMD drops the ball, when do you think Nvidia will be inclined to bring better performing cards....sooner or later? or milk another low incremental step? I know you get it. Just explaining why many seem concerned by any AMD mistep. biggrin.gif  

I agree with what you said in principle, but let's just say there are... less inflammatory ways of "spreading awareness".

There a post on Reedit that the card is showing a max use of 1.3v at peak so maybe that why is getting that watt

This is exactly what came to mind when I read toms review today. I melted and I do mean melted a 24 pin connector with three 470's in sli during a spirited benching session. Like they said in the article one card out of spec should be fine but you start pulling even more than that and you may very well have a problem on your hands.

Yea I had a 470 catch fire to a gigabyte board I had at the PCIE slot back when I had an i7 930. I don't think back then they did these exact tests on cards during reviews, which brings me to ask... why now... but I'm sure that that generation had a similar issue considering the high power draw.

Was the component that could not handle it the motherboard or the cable? Would using 16 gauge instead of 18 gauge cables help? (obviously not if it was the mobo)

Well from a data sheet on one PCIe connector ( the actual plastic connector ) , each pin is rated for 2.2A and there are 5 of the 12V supply pins on the PCIe socket , so in theory the quality sockets could support 11A ( 132W ) from the 12V rail though the connector

Haven't certain cards been stepping outside the spec for years? Talking about a decade... nobody has complained about it thus far.

People be overclocking and sucking 100w through the PCI-E slot, hide yo power supply, hide yo motherboard, hide yo overclock cause they all be out of specification up in here.
