Few Q's - CPU-NB and Vdrop

post #1 of 3
Thread Starter 
Hey,

Seen lots of stuff about CPU-NB overclocking and getting the right speed for your OC but no guide on how to find it. Anyone know? Mine's at 2500MHz atm and there's a definite performance increase, but I wanna find the optimal, is it really just trial and error? Also am I right in saying the HT Link needs to stay at 2000MHz?

Current settings:



CPU volts are at 1.475 in the BIOS so I presume the 1.375 reading is wrong, I know this board has Vdrop issues but I can't see it being that much.



What would you do with it in my position?

3.5GHz is the max this CPU goes without going upwards of 1.5v so I'm keeping it at that. RAM Volts are at 1.6V.

Specs in sig.

Cheers

CPU-NB and HT Link speeds info

Geting to the highest possible CPU-NB speed depends on much factors, and is pretty much like OCeing your CPU and RAM, trial and error. With those settings and sice you don't want to push your FSB higher than 250, you can try and test CPU-NB multipliers of x11 and x12, 2750MHz and 3000MHz respectively, for stability and perfomance. Keep your HT link at 2000MHz, as you will see that a higher frequency won't bring you better performance in the thread linked above. You may need to increase the CPU-NB voltage in BIOS, but try at stock volts first.

At 2500MHz on stock volts, fully stable atm so room to push it with

Gonna try FSB at 350 again but lowering the CPU multi too.
