Hey guys, today I have tryed to go from my stable 4.6ghz overclock to 4.7ghz.

The settings for my stable 4.6ghz OC are pretty simple(1.25 vcore and 1.808-1.836 VCCIN)

This with XMP enabled.

Now the first thing I tryed to do to achieve 4.7 was increase the multiplier alone and ran IBT on high and passed.

Next I ran Prime 95 Custom FFTs in place 1344 length...failed with a BSOD 101 error(VCCIN)
Ok so I increase the VCCIN to 1.9(it's 1.936 under load in Prime) and run the same test again. Both pass and stable after 1 hour.

I proceed to run the full small fft test and 2 hours in I get another BSOD(124)
Ok...so now my Vcore is inadequate, so I bump it from 1.250 to 1.255

Am I on the right path to stability @ 4.7ghz guys?

My temps are reasonable though...my max is only 74c with an average of 69c. I am certainly not hitting a thermal wall.
I'm on a watercooler with a dual fan 240mm radiator, not air.

In any case it failed on 1.255 at the 5 hour mark this time.
I increased it to 1.27v and running again.
The BSOD's(101,124) correspond to a voltage, not thermal issue

My current settings are:
VCCIN: 1.900
Vcore: 1.27
Speedstep: Enabled
C States: Auto
Offset: Auto
Uncore: Auto
Multiplier: x47

Hopefully it is stable by the increase to Vcore this go around, but if it's not, surely theres something else I can tweak?
