Reports of RX 480 damaging PCI-E slots - Page 14

My motherboard did not shut itself down to protect itself. This was in an open air (milk crate) mining rig when I first started. An extreme case I would think/hope.

From the PCPer video, they went into detail explaining that the pcie pins were rated for 1.1x5=5.5a total, unlike the gpu 6/+ pin connectirs that have much more to offer. Im eagerly awaiting to see AIB products.

I had a similar issue, on a 4 way classified evga x58 mobo and 4 x 480gtx - my fault was i forgot to plug in the pcie aux power plug - When i noticed something was wrong the system would shutdown like it was PSU OCP. It did this about 4 times as i thought i was just hitting the limit on PSU's. then i decided to just double check the system and found 2 wires on the ATX 24 pin melted at the ATX connector and down the modular 24pin cable. The end result was i replaced the 24pin cable, and removed melted plastic at the mobo atx plug. The mainboard still works perfectly fine to this day, and the PSU i had also still works. After that, i made sure to use the AUX pcie power on it and any Mgpu setup i have done since.

The OCN user Cubeman reported he lost audio on his Rampage IV Extreme with tri-fire rx 480 in this thread. It's interesting because i have a buddy of mine who had a similar issue with his Rampage IV Extreme and he had 4 GTX 570's in his and his sound is broken. I will reach out to him tomorrow and find out exactly what his audio issue is.

Then there is the spamming of this video. Warning: Spoiler! (Click to show)
So i would conclude you are coming across as a Nvidia fanboy, but that's not accurate. You are someone who has bought some of the most expensive GPU currently and has previously bought cards like Asus Ares. I think your issue is your and enthusiast who looks down on lower end cards. with the exception of promoting the GTX 970 which leans you toward Nvidia fanboy zone.

I have to ask though why you care so much about hating on the RX 480 when you have a 1080gtx? It's obvious you were never going to buy it.

Edited for grammar crackers yum yum.

Im just being very real. All i said is facts. Sad facts. I was hoping for something better. We deserve better from amd. Im disappointed.
They dont learn from their mistakes.
Gtx 970 is still a good card and if you like nvidia then you dont do a mistake if you buy it over rx480, considering the same price.i wouldnt buy a reference 480 cuz of obvious reasons.
If theres afternarket rx480 then maybe the card will be ok.
At the moment with the reference card i cant say they keep what they promised and sadly they are 2 years behind nvidia in terms of architecture. The hype is just not there.
My belief in amd has cost me a lot of money. Freesync monitor, swapping different amd cards cuz always some issues with them then selling all of it...
My point with gtx 970 is ....choose wisely now with which team you want to go before its too late(buying monitors) cuz it will cost you a lot of money then to switch and 970 is not a bad choice if they cost the same.
Pce

AMD are definitely 2 years behind Nvidia, which is why AMD have Async and Nvidia, despite their lies, don't. When Nvidia's CEO said their cards were DX12 and Async compatible he meant they simply wouldn't render DX12 code and ignore them. The great and wonderful 970 has 3.5+0.5GB RAM, not 4GB. The 1080 can't run refresh rates higher than 85Hz over DVI because it's 'out of spec', something even my old 9800GTX+ can. They stop optimising for their chips long before the release of the next architecture so that the next one looks better than it is (was proven at release of the 1080). Have GameWorks (GimpWorks) that impacts their own chips more than AMD's as AMD can set tesselation levels in drivers. Can Nvidia's own drivers do that? Enjoy your useless over tesselated, invisble underground water at 64x.

I found this quite informative:

Clearly the cards runs at stocks avg above spec, is it a lot? no but avg is above constantly above spec both watt and amps on the pcie slot on Stock in gaming.

Exactly about the 24-pin connector. The issue is, that there are different brands of slots used, also different brands use different amounts of solder for the connection. All it would take it s crappy board with a crappy PSU, and maybe we can see which would burn first hahaha.

I'd send a PSU straight to the trash if it drooped that bad on any rail at anywhere near its rated load.
It's the voltage drop from their extender, they increased the distance/length of the PCI-E pins with wires. I am personally interested with what method they used for current measurement, most DAQs measure voltage (and they are using an NI DAQ b/c LabView is NI's program, I have one). To measure current you need to break the connection and put something in line, or use one of the current clamps usually meant for a scope. I don't see a clamp and in their article they didn't specify how they measured the current. Did they use a hall effect sensor IC, clamp, or shunt (very low ohm resistor where you use ohms law to find current) ? Maybe it's explained in the video, but I don't like watching videos.

I played overwatch, gtav, BF4, Doom, and AoTs for around 10 hours the last couple of days. Clocked at 1350/2200. No crashing, artifacts, or other issues. My mobo is pretty cheap as well, msi 970a-g46

And GTX960 750ti averages below 75w I think. But spikes alot like 200w which should be an issue even if those are just spikes
Many had spikes, just no one cared to look into. 295x2 was mentioned. Used way more power than what specs allowed.
Actually 295X2 used only around 30-40w through the PCIE lanes. It just powered the pumps and fans IIRC. The rest of the draw was on the 8pin cables. Over 220w stock each!

Even the 960, 970, 980, etc. do this. When some random fool on some forum says "AMD killed my motherboard, you'll be hearing from my lawyer." you know you're either dealing with trolls, immature little kids or immature little trolls.
