Hi guys, first post. YAY! I need some help getting my c0 to 4Ghz on my UD5... Many failed attempts. I'm currently at 3.8. I am no expert, this is my first build and overclock. I'm using the F7 BIOS.
Current settings are as follows:
BLCK: 200

QPI: 7.2
Uncore: 2.6
RAM: 1200
Vcore: 1.35
QPI VTT: 1.335
CPU PLL: 1.88
QPI PLL: 1.34
DRAM: 1.66
LL Calibration: Enabled.

What shall I do with the IOH Core, ICH I/O, and ICH Core?
