Flickering screen and X-Server crashes

KHGug — Sun, 15 Sep 2013 14:44:16 GMT

Hi there,

I'm experiencing problems with my i7-4770S graphics. The screen sometimes flickers, producing horizontal bars, about 100 px in height, moving up and down. The bars are not fully colored green, more like a chessboard with the normal background content and the occasional green pixel. The green pattern, in the same time, seems to move left or right. I was not able yet to capture it on camera. The flickering occurs in any OS, including BIOS setup.

Additionally, from time to time, my X-Server (Fedora 19, Linux 3.10.11) and/or single X applications crash.

Backtraces from Xorg.0.log.old and libxcb crash information from dmesg:

Hardware:

Asus H87M-E (C2)

Intel i7-4770S (bought it boxed)

G-Skill F3-10600CL9S-4GBNT (2 x 4 GB - worked fine on another Asus board)

Samsung SyncMaster 2333 monitor (works fine with other computers)

Does anybody know what exactly is happening and what to do to fix it?

Regards

I suggest that you forward this feedback to the following community for further support on this:

https://01.org/linuxgraphics/community https://01.org/linuxgraphics/community

Keep in mind that some generic precompiled versions of Intel graphics drivers for Linux are available on the Downloads section of the Linux and Intel graphics* Web site. Support for these precompiled versions is only available through the open source community

You may also refer to your Linux* Distributor for further troubleshooting on this issue.

Problem disappeared after changing the RAM to Corsair ValueSelect.
