Sapphire 280X crashing

ItsTheDEMON1997 · August 17, 2016

Hi,

About half a year ago I built my first pc:

CPU: i5 6600K @ 4.0Ghz and 1.200v.

Ram: Kingston HyperX Fury DDR4 2666mhz 8GB (1 stick)

Motherboard: MSI Z170I pro gaming ac mITX

PSU: Corsair CX750M semi-modular

In a Corsair Graphite 380t case and a cheap AIO watercooler on the cpu.

After I finished this build, I didn't have any budget left for a GPU so I bought a second hand Sapphire 280X Dual-X OC.

This one:

I paid 130 euros for it and I benchmarked it in (I believe it was...) firestrike with a friend of mine. The card showed no problems at all and it looked like it was brand new. When I got home I installed the GPU, installed the drivers and did some Planetside 2. And it crashed...

I noticed the card got hot, about 75-80 degree's celsius. I opened afterburner and made a fancurve. The card didn't get that hot anymore (about 65 celsius) but it still crashed. It crashes less frequently, but it does and it is very frustrating. When it crashes I get a white screen (sometimes other colors, but most of the time white) with vertical bars. It makes a very anoying sound, and I need to restart the pc to get rid of it. When I open up afterburner, all the settings are resetted. I also noticed the right fan appears to be spinning slower then the left one. I also think this card has been used for mining. I tried a lot of drivers, I did the DDU a lot of times, I tried a lot of fancurves (even full time 100%), I tried underclocking it, removing the overclock of the cpu or resetting the CMOS didn't work either, I tried giving it a higher power limit but the result is the same. Sometimes it takes longer, but eventually it crashes. I cannot afford a new card at the moment, so I would really like to solve the problem. I hope someone has another idea. I am aware of the oven method, but I don't know if it can damage the card even more. I have also put some new thermal paste on the core, but it didn't make any difference.

It could be the psu, the older green corsair cx series are not known for being reliable.

The Oven method is not recommended at all, it will most likely break the card if it goes wrong, and the oven will be rendered dangerous to use for anything that you would want to put in your mouth since you release a lot of chemicals by heating the card.

Thank you for your reply,

If I was going to use the oven method I can use a small cheap oven we don't use anymore.

I asked a friend if we can test the card in his system and he said yes, so we will know if it is the psu soon.

I thought the psu was a good one, I paid 100 euros for it because I heard about the horror storries with bad (cheap) psu's

Weird... I can't remember what the PSU looks like but when I open the case I can see a black PSU with a white sticker and a black M, the rest is behind a piece of the case. It doesn't look like the photo of the one I ordered.

Maybe I can find the box it came with.

I think I have this one:

Is it a good PSU?
