aights. First off. System specs would be nice. Name your mobo, Ram etc. Otherwise generally here are a few tips:
keep your HTT mhz under 1000mhz. So generally, change your LDT multiplier to 4x.
You MIGHT consider a ram divider, depends how good quality your ram is.
Chipset Voltage: change it to 1.6-1.7volts.
Post your cpu voltage, you might concider upping it up abit.
