5ghz Not Stable , Crash as soon as i run Prime.
Stable o/c when burnt with prime. But temp are going in the low 80s with my h100.
(here in Australia it's summer. 45C outside about 30/35 inside in the afternoon.)
Would probably hit mid 70s if i tried in winter.
i hit the low 70s now with my constant oc @4.4ghz 1.2V burnt with prime95. other wise low 40s idle . . . mid-high 50s when gaming.
