Recently I switched from an Asus Sabertooth FX990 to a Crosshair V Formula Z for my FX9590, and I was pretty happy about the results, previously I was only able to reach DDR 2133 10-11-11-30, I was never able to reach the XMP settings of my DDR2400 16GB ram in the sabertooth.
However in the Crosshair I easily set the XMP settings and seems stable under stress tests and 3D Mark but when attempted playing Overwatch, Rise of Tomb Rider and FarCry3 I get random crashes, It wouldnt be an issue if I could get any other setting stable, but unless I set them at 1600 with the same timings, nothing else works.
DDR1866 get me a blue screen during windows startup, and 2133 has stability issues under 3D mark or any stressful workload, all were tested under the xmp timings that are quite loose for those low frecuencies.
The timings for 2400 are 11-13-13-31, I have tried auto settings with 2400 and even as low as 1600 and still cant get them stable, also have tried 2400 with loose timings with even worst results.
Last night I tried everything, I fixed the CPU in a stable clock and voltage (4.0Ghz 1.4v), loosened timings (14-14-14-38...), raised memory and Northbridge voltage, and still no luck with stability.
The only setting that appears to be stable is with manual xmp timings but 1600 frecuency.
I will try other sticks I have around to see if I can get something better
