Is this a faulty graphics chip? ;'(

[fabiosapplou]

Hi guys, i'm wondering what is these thing that comes and goes, sometimes flashes in and out. What can it be? Fist time it happened today, no trauma to the laptop at all.

Any recommendations on that to do?

You could try lower the memory clock speeds.

Yeah that would also be my guess ... one or several memory chips on the video card probably have errors

Will it be solved if i find the memory ic's? and solder new ones in place?

if you think you're that good... its extremely hard to do as they are so tiny. Is the laptop not under warranty anymore?

[mariushm]

By yourself, you probably won't be able to do it. Some service center would be able to replace memory chips, as long as they have the chips or can harvest working ones from another laptop / video card / etc

If that's a laptop, if you're lucky enough to have the video card on a mxm card (removable) then maybe you could just replace the video card

If it's just the IC's i can manage it, i work with electronics. If that is the problem is a matter of finding the chips. Thanks for the help!

Test your video card's ram first though...

I remember seeing on some russian Youtube channel that has repair videos a software which even told which memory chip is most likely to have the errors based on the addresses where there's failures... but I really can't find it right now (murphy and all that, of course)

Pretty sure you're better off just replacing the motherboard in that case, you might be able to find one on ebay or something

They probably test the computer ram, not the video card ram.

Did you try lowering the GPU clock in overclocking software?

No, i don't really know how to do that man. The laptop in an Acer V3-772G

Just download MSI afterburner, or EVGA precision X and lower the memory clocks if possible.

It does not go away still, if flashes more often though. But comes right back again.

RAM is also fine.

Then try lowing the GPU clock too
