Hey guys,

I could use the help of the comunity to overclock my CPU.

I am aiming for a 4.5 Ghz stable permanent OC.

I ran it at the following settings:
- x40 - vcore auto - stable*
- x41 - vcore auto - stable*
- x42 - vcore auto - stable*
*No other settings modified.

- x43 - vcore auto - bsod in prime 95
- x43 - vcore 1.29 - stable*

- x44 - vcore auto - bsod when booting in to windows
- x44 - vcore 1.34 - bsod in prime 95

- x45 - vcore auto - bsod when booting
- x45 - vcore 1.36 - bsod in prime 95

First I wanted to reach 4.5 without modifing other settings and then rising the the Cache.
The ram was at 1866 stock - auto voltage - 1.5

Thanks,
Gabriel

Going above 1.3v isn't a good idea. Returns aren't worth it for the temperature increases.

You chart there looks quite similar to mine. I run at 1.2894 (1.29) to achieve 4.3Ghz. I got it stable at 4.5Ghz with 1.35 volts, but the temperature was about 100C.

What temperatures did you measure at each of those voltages under load?

Have you also been looking at LLC and Vin (Voltage input) to the CPU. Vin will need to increase as well. LLC can help with stability.

My temps are somewhere above 70C. I have the h100i and the cooling is not an issue...
I also tried increasing the vccin with the same result :)

I could buy a 4790k and sell this one but I thaught it's not worth it.
I will try to tweek it again tonight and see what happens.

Last time I messed with it I had my h80i in a push only configuration. I've replaced my old GTX580s and had room to put the h80i in properly and since I had to reseat it anyway, redid the thermal paste. Not sure which did it, but dropped another 10C off the top. Rarely see it go over 70C now, but I haven't tried for 4.5Ghz again, just don't think the IC can do it at a reasonable voltage. And I would like it to last at least until the Broadwell chips are out. The process shrink should have an interesting effect on this architecture. (I'm thinking 5 Ghz)
