And the e3g3 is probably the best performance for $ mobo I've ever come across. thumb.gif
Is there any trick for having a better oc on the extreme3 g3?,,maybe i would send you a PM when I start ocing in these days

well I am using a nh d14 which is performs as an h80i.maybe your numbers are far from mine.

No tricks for a 24/7 OC. Follow kenny's guide and you'll find out what your chip can do with reasonable temps. No problem if you PM me.

Which was your cooling before that h110 amd which was the vcore for that same frequency compared to the vcore that you are using right now?@cravinmild
post #24 of 30
H100 died while using these same settings. Temps were lower with the h100 p/p uk3000 compared to stock 2 fan h110. 110 got cooler temps when i switched to p/p.

I used custom bios settings which i got through trial and error but current oc settings use the presets built into the bios. 4.3/4.6/4.9 all have default voltage and mulitplyers. Only 4.3 work without boot issues.

Not sure if that answers your question

partially

My maim concern was if a better cooling like the way you did ,would make to a cpu need less vcore
post #26 of 30
FYI, I got my 2600K @ 4.6GHz with 1.395V manual set in BIOS with a Silver Arrow cooler (like yours...)

I'm doing this for a few years now, no problems/BSODS/degradation once so ever so I'm happy with it... tho I see A LOT OF others with better results thinking.gif

Oh well thumb.gif

Again, it will not. Not with ambient cooling. Air to water will not do it.

See posts 2 and 4. thumb.gif

I promise if you keep asking, you will get the same answer (from those in the know).

Indeed... better cooler will lower temps. But lower temps does not mean you can lower the voltage (that the cpu WILL need to operate at that frequency)

In other words:

The cpu needs x volt for x GHz regardless of the heat. So a worse cooler can do it or a good cooler can do it. But the worse cooler will heat the CPU, and the better one will heat less

As mentioned previous all CPUs will require different voltages for different over clocks. Better cooling only allows you to push more voltage while maintaining safe temperatures. More voltage produces more heat hence better cooler needed. I'm i'm unsure of voltage cooling relationships outside of this fact sorry. For me personally have not noticed reduced voltage is because the better cooling
post #30 of 30
It is not until you get into sub-zero cooling where this becomes true. Ambient to LN2 allows me to run a few hundred Mhz higher at the same voltage for example.
