Flickering screen and X-Server crashes

[KHGug]

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

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.
