AMD RX 480 DID NOT brick my motherboard. Water leak? - Page 6

post #51 of 164
I once had a similar incident, with GPU killing the motherboard at boot, but in my case, the culprit was...myself. I *thought* i had put the GPU correctly in the slot, while i hadn't. The rear part of the GPU was slightly outside the slot, while the front was latched correctly (at least as i recall, but bottom line is, the GPU wasn't fully inserted in the entire lenght of the slot. And as improbable as it may seem, i 've had it happen again years later, but i saw it in time) . Now this was back in old days. Upon switch on, a flame poped out of the slot for 1 second and killed the motherboard and GPU. Upon inspection, it had burnt through the motherboard's PCI-E slot and even scorched the right panel of the case. Just in 1 second. It wasn't even a high TDP GPU. An NVidia FX5200. So it wasn't the power draw that killed it, it was the bad contact inside the PCI-E slot.

I know, you didn't see any scorch marks, but maybe newer motherboards have better protections to avoid this, but still can get similar deaths. Just a hypothesis.

Shame for the Sabertooth. RIP. Shame that it happened out of warranty too... If you want a cheap motherboard capable of 4.4, you can get the Giga 970 UD3P. Although for a bit more, there is the ASUS 970 AURA that is much better.

Disassemble your entire rig. Bring the motherboard out of the case and have it standing alone by itself. Then hookup your cpu cooler and connect the power cables to the motherboard and try to boot it that way. Maybe if you have an air cooler try that too, just to rule out the wb. Taking her out of the case should rule out a short...

I'm on a tech station, the photo in my avatar. The mobo is mounted to stand offs that mount to acrylic panels. If theres a short, its on the board.

I'm starting to get the feeling a little water got in the board. Even tho I've been water cooling for YEARS and have had zero issues / leaks, maybe a small drip slipped past my observation when swapping from gtx 580 to rx 480. Entirely possible I GUESS. That may explain the hissing sound... water boiling and shorting on the board? lol, Im so screwed.

UUGGGGHHH!!! redface.gif

And apparently my rigs WEREN'T showing, just figured out how to get them too... lol

A much more reasonable and rational explanation than your initial besmirching and hyperbole, wouldn't you say?

Every time you mess with your board like when changing components you run the risk of damaging it.

What may seem like an indestructible piece of hardware for many years can be rendered inoperable in a split second with the slightest spark or spike in power.

Especially on a board that is 5 years old.Just touching the board when it has power in it can do it.

I once connected a 12 cm fan to a live pc header, didn't have ethernet any more until I changed the motherboard. I should sue the fan manufacturer.

I did say. You have to remember I was absolutely irate beyond rationality. I, like most, work very hard for the scratch i bring home... I literally CANT afford a new board. I saved up for months for the measly $260 the RX 480 cost me. When I swap GPUs and my board is dead, I'll blame the only variable that changed... THE RX 480.

Even if its not the card that dmg'd my board, its still the intention of changing to that card that caused the issue. So yeah, the RX 480 did blow my board. Because if I hadn't swapped GPUs, the machine would function still.

Reading the original post 7 cpus and 5 gpus is an incredible amount of different hardware being plugged in and out of that board, this can cause wear and tear on the PCIE slot?

Also the fact that it is bricked and never even fired up with the 480 is really strange.

I think anything could have happened to it, could it have been the 480? Sure.

But I can understand the scepticism but still people should not be calling the OP shill or troll and what not it's uncalled for.

Like I've said, I usually go nVidia for my GPUs. I just wanted to go all AMD again.

The RX 480 is going to be given a fair chance at proving itself tonight on my core 2 duo combo sitting in a box in my closet. If it works out fine, then I'll consider my loss due to water somehow getting past my observation, and continue to test the CPU first on a friends machine. If CPU is fine, then a replacement board will have to happen, or I wait til AM4, and sell all my left over goodies. CPU, RAM, all water cooling (lets face it, W/C isn't THAT much better than air, depending on environment) and i can forget about the mess that W/C really is. Plus I can't risk losing my gear because of WATER. Atrocious.

I've been on this forum for a GRIP. A shill or troll, absolutely not. Irate and very upset at my hundreds of dollar loss, you can bet your donkey.

PCI-e 1.0 specs had only ONE 12V pin, and other "reserved" voltage pins.

This is why the limit is 5.5A, it is what the manufacturer of the PCI-e slot claimed was the safe current when the pin is at 60C (temperature).

PCI-e 3 (I dunno about 2!) has 5 12V pins, rated at 1.1A (this mean if a manufacturer want to make a slot that has pins that work at most at 1.1A, he can... the expectation though is that most mobos will use 5 5.5A pins)

Since the 480 pulls 7A from 12V pins (or more even, depending on programs you are running), it is to be expected it will destroy PCI-e 1.0 slots, and can damage newer slots if there is bad contact (ie: if dust or whatever gets in the way, or the mobo doesn't actualy have 5 pins in first place).

Also people underestimate how quickly things can go wrong with electricity (some miliseconds are enough for something going wrong cause a spike in temperature and resistance, increasing current too, and causing a exponential runaway effect, that results in arcing, noises, funny smells...)
