[Bug 32911] [RADEON:KMS:MEMCORRUPTION] random memory corruption if using more than 4GiB of RAM on Core i7/P55
https://bugs.freedesktop.org/show_bug.cgi?id=32911 Siarhei Siamashka changed: What|Removed |Added Status|NEW |RESOLVED Resolution||INVALID --- Comment #5 from Siarhei Siamashka 2011-03-19 02:56:03 PDT --- After all, it looks like it is a hardware problem on my side. Experimenting with 'memmap' option simulating 4GiB setup precisely does not help when all 8GiB are installed. Also reducing RAM speed from DDR3-1333 to DDR3-1066 or DDR3-800 makes the problem significantly harder to reproduce, but does not eliminate it completely. And looking around in various hardware forums, reliability with all four DIMM modules installed seems to be a rather common problem. Appears that llvmpipe is just a very good memory checker, putting a lot of stress on all CPU cores and memory controller, exposing problems which don't happen in other use cases. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug.
