EDIT: (BIG EDIT) This is under Zenith Extreme Alpha, I did not have many of these issues with the OG Zenith Extreme.
Yeah, I doubt you are "stable" unless your definition of stability is no BSOD. I'm kinda stable with 2 ram errors in 8 hours using Stilt's Safe 3200 4xsamsung b-die Preset applied on a freshly flashback OG BIOS (because 0405 gave me some weird smp error under linux). I cannot get 100% error free memory whether or not I OC the CPU, unless running JDEC 2133.
With this set up I got myself a stable CPU (enermax 360 AIO II idles 37->41 C) and a *mostly* stable RAM
1.4V with 2 errors in 8 hours of karhu (tho some say it can push much higher but @3466 it passed 1smus's v3 test but not karhu ram test)
this happend to me again this morning... what'up up Mobo is dying ?
I've had issues too . Do you ever hit that safe boot button on the motherboard? Sometimes I have success wishing the power supply off and then back on to do a hard reset when the motherboard seems to freeze up. From the accounts I've read it seems that the original zenith extreme is a little bit more stable than the zenith extreme alpha.
