cuda error - an illegal memory access encountered

Aekash · Feb 20, 2018

I have a P106-100 Graphics card which crashed halfway through mining.

When I now run the miner software I get "cuda error - an illegal memory access encountered"

I have rebooted my PC and I still cannot resolve the issue.

Is my graphics card knackered ? is there a way to reset the memory (I am assuming somehow the memory is not being refreshed after a device power off)

@cdawall Probably best person to help you
Have tagged him
he will be along to help you hopefully soon

Some have mentioned it's an issue from power states. You need to use Nvidia inspector to turn the P2 state off.

@erocker thanks, I will give that a go and report back

Which specific miner is causing an issue?

Aekash · Feb 21, 2018

I've got a 8 GPU machine where one of the GPU's is knackered

I'm using EthMiner

The error occurs when attempting to generate the DAG file

Maybe while mining it encountered pocket with methane and exploded, use non pyrophoric tools.

What happens when you take the card out and try running it all?

qubit · Feb 21, 2018

I see that this is a mining specific card. Are you able to run the card on its own, ie remove all the others from the rig? If you run a different card on its own does it run? If the answers are no and yes, then your card is likely faulty. It might also help to try moving it to a different slot if you get an error when testing this.

Indeed it is a mining specific card.

Tried everything you suggested. Only thing I can think of is the memory blocks are somehow corrupted (but I would expect the memory blocks to be cleared down after the device is powered off and back on)

Anyone aware of any software to check the integrity of GPU memory and fix any memory related issues ( assuming the memory blocks are not cleared down after a device is powered off)

Like a stick of ram, it's rare, but GPU memory can go bad. This is likely what you are seeing. If so, no, a program will not fix it. A quick warranty claim might though.

many here will be intreasted on how any warranty Claim goes (re with the news of Specific 90 day warranty's)
if you RMA PLEASE KEEP THE THREAD( AND US) UPDATED

Unfortunately the card is indeed faulty in that case. How long did you have it before it failed? I'm curious, because mining is known to hammer graphics cards which are working flat out 24/7.

I'm not miner but find this interesting and I agree with @dorsetknob, do keep us updated on how things go.

Any OC and are they 6gb cards?

Does not work with OC or without OC

They are 6GB cards
