Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[pikachuy]

Well there are a lot of reports of PCI slots crapping out, I came home to this in my rig that had 3 RX-480s in it.  They all went back for a refund today.

Can you answer the following?

Were you dual mining?
Overclocking?
Increase Power Limit?

That is what happens when you draw more than ~ 300w thru the 24pin atx connection and the reason we use powered risers. Which in the case of the rx 480 does not seem wise as the meager 6 pin pci-e connector isn't upto the job, particularly if you overclock and or increase power limit.

No, it's an Asus P7P55-LX, it was the 1st rig I built.  Ran for 3 years with 3 280x and non-powered risers.  6 hours with the 480s and poof!!

[hawkfish007]

Were you using powered USB risers? Was any of the card connected directly to the motherboard?

[BitJunkie223]

You need

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

I guess that response was to me?

It seems like those settings applied on my main rig, even though I never edited any of the settings other than pool...

But do I do that in my .bat file, or take the "#'s" away in the config file? I could try it, but I don't have my other system on currently, so I'm just asking with what I have in front of me. But thanks for your help so far. I hope that does the trick.

I believe he said all gpus were connected directly to the motherboard. In this case with the rx 480 I doubt powered riser would help much anyway because the card would draw too much power thru the riser and end up melting the molex connected to the riser (which is admittedly preferable to melting the atx connection on your motherboard). Still it seems clear the 6 pin pci-e connector on reference rx 480 is insufficient, I will be waiting for aftermarket cards before venturing into mining with polaris.

wrong he was using unpowered ribbon risers , recipe for disaster long term

[BtcCrazy1]

I have 2 480s plugged directly on my mobo, and I've had no problem maybe I should don't understand why it would burn up there and not the pci port.

Even if you use the riser cables it wouldn't help in the event of that because the same power would be going to your mobo from your power supply.

Powered risers have a molex power connector that supplies power to the card.  All power pins on the PCIE connector are powered through this connector not the mother board.

[merc84]

The issue with using powered risers would be drawing more than 75w thru them since the 6 pin pci-e is insufficient to supply all the power the rx 480 needs it will try and draw any additional power thru the powered riser which is likely to result in melted molex connections.

No wonder, 480s were destined to fail from the beginning. My slightly overclocked 480 takes about 170 watts at the wall with gold PSU, 6 pin pcie should be absolutely fine, unless I am not aware of some PCIe limitations.

Aticonfig shows 100% load but card stays cool and hashrate low.  With ethminer I am around 30MHs with this card.

The issue with using powered risers would be drawing more than 75w thru them since the 6 pin pci-e is insufficient to supply all the power the rx 480 needs it will try and draw any additional power thru the powered riser which is likely to result in melted molex connections.

This is the reason I don't use the molex to sata pigtails that are usually supplied.  Mine are soldered directly to the holes on the riser board, although you should have no problem using the molex connectors from a good PSU. Molex connectors are supposed to be rated at 11A per pin which means a 12v molex connector could supply 132 watts per card.
Connecting directly to the motherboard means the circuit board traces and ATX pins have to supply 3 cards not just 1.

[BtcCrazy1]

So my 1300 watt evga 6 pin won't supply enough power to my 480's? I could understand if your using a not powerful enough power supply or not a single rail because that card should be pulling as much as it can straight from the 6 pin correct?

Just seems weird as I would feel like it would keep trying to pull from the 6pin and that would burn out that connection or kick off the power supply..

I just don't understand why it's not burning up the pci slot as it's only rated at like 75 watts or something correct or depending on the board?

Are the powered risers connected straight to the power supply?

Your 6 pin is fine. But the 480 needs 75W or more from the PCIE slot if you overclock, that is the problem.

... that means powered risers only will not be enough if you OC? Likely need molex powered too, in case of H81 mobo.

I am guessing probably that's why my rig has no issues because the risers are powered via SATA from PSU. And the ASrock H81 Pro BTC board has also molex powered drawing from PSU. With both of them powered, it will give enough juice to 480 when OC.

Meanwhile, with same mobo setup, I have 5 x 390s OC to 1050Mhz/1125MHz giving me 30.5MHs per card, and no issues with that too. Both risers and molex are powered. The 390s draw much much more power than the 480s.

6 pin pci-e is rated for 75w, mboard pci-e slot is rated for 75w while the rx 480 is rated for 150w it seems to be drawing slightly more than this @ stock settings. If only Amd had used an 8pin pci-e (rated for 150w) connector it wouldnt be an issue.
Yes it can depend on the board some manufactures design with higher tolerances than others, it may also depend on cost cheaper models for example might has less tolerance to help reduce cost.
Powered risers can be connected via molex directly into the riser board or often are used with sata to molex tails that commonly ship with most usb risers.
