questions about overclocking my QX6850

[kaitlin4599]

ok so i have a QX6850 that is liquid cooled via an AIO. temps idle between 37-40c. at max load in prime95 in blend test at stock speeds 3.0GHz temps max out around 56-57c. while not new to overclocking my previous chip was a core 2 duo E8500 im new to overclocking quads so i have a few questions

#1 what temps should i watch out for while stress testing in prime i.e. keep CPU under X temp/temps when stressing for stable speeds

my goal is to reach 4.0GHz stable 24/7

#2 aside from reading the overclocking guide on here is there anything else i should know ABOUT MY QX6850 IN TERMS OF OVERCLOCKING I KNOW THESE THINGS ARE KNOWN TO BE HEATERS

lastly should i test under small FFT's or blend wanna make sure both cpu and ram are stable

also what options do i disable in the bios so while stress testing the cpu will run full speed all the time and not lower its multi and stuff

BEFORE I FORGET im using MX-4 as my thermal paste below is a link to my AIO just incase

AIO is run in push pull setup because i had the extra fans lying around

Its all in the guide we linked to you before....

Just for those interested this is also posted at OCN here http://www.overclock.net/forum/5-intel-cpus/1661745-help-overclocking-qx6850.html
You should post those links when cross posting sites Kaitlin that way we're not repeating information that has already come to light in another thread.
All the answers you seek are in that guide http://www.overclockers.com/forums/...lock-C2Q-(Quads)-and-C2D-(Duals)-A-Guide-v1-1
Intel recommends 65° for max but those chips are pretty tough with people running them in the 80s but I would think a 70° goal would still be conservative enough to aim for.

It's kind of hard to measure Tcase temperature, folks need a thermal probe between the IHS and CPU cooler. Tcase is usually 20c lower than Tjmax core temperature.

Just trying to be conservative. I treat them a lot differently and haven't killed a C2Q yet

Tjmax is either 90c or 100c on those iirc. I vaguely recall needing to keep these under 80c or they tend to lose stability.
