MSI 290 horizontal lines?

Hi all,

I've got an MSI R9 290 Twin Frozr which is behaving strangely. When I first received it (second hand) it was running hot, up to low 90s celcius in the furry donut in Kombustor, so I decided to repaste it (something I've done may times before on other GPUs). Retesting it, it's now maxing at about 80C in the same test (about where I would expect), but there are random coloured horizontal lines appearing on the screen.

I don't think I could have damaged it (same procedure as always), so I'm wondering why I didn't notice these lines before the repasting.

Does anyone have any ideas what might be going on here?

Thanks in advance.
 
Well it's either bad luck or you might have accidently damaged something during the strip down.

I'm assuming it had thermal pads on the memory? Maybe one of them is misaligned

Kombuster and similar have a bad reputation as putting to much load through a card purely to raise temps which will not be seen in gaming.

Don't know if you would get similar symptoms if you didn't have a good core contact all over. May be worth stripping down again and double checking everything.
 
Kombuster is a power virus and can damage cards. Also as you state it was working fine before you took it apart too, so either you damaged it when repasting or with Kombuster.

You can try again to open it up and make sure nothing is shorting or not making correct contact.
 
Turned out to be the HDMI splitter I'd just started using. Was working fine with 1080P signal, which is why I didn't twig it straight away. As soon as I tried to run 1440P through it, it generated a bunch of coloured lines on the screen. Shame really - the splitter works well for 1080P signals.
 
Good to hear you figured it out. :) yes splitters of any kind can cause strange things like that, in your case the splitter can't do over 1080P it seems. You may need a better quality one that is more aimed at PC monitors and not the general AV market for TVs. A 4k HDMI splitter may give you a higher than 1080P signal that works.
