Hi I have rampage v extreme with 6900k h110i gtx and gskill tridentz 3200mhz 15cl memory

I can get the system to 4.4 using the preset for 8core overclock in the bios then set 4.4 to all cores. I have the cache oc to 3.9ghz
when I set the cpu to 4.5 its not stable unless I boost the volts to 1.41 or more though the heat goes up. also cache wont go beyond 3.9 though I haven't turned up the cache voltage.


the cpu runs hot 80c + max during realbench stress test though during gaming it stays around 40c +


anyone know any tricks to get it to 4.5 ? or higher cache speeds? also is there a better cooler out there or is there something wrong with mine?

Thanks.
