examples in sig already - finding that balance between the 2 voltages will allow your memory to clock higher/more stable. How you find that balance is through trial and error - i start with memtest86+ v2.11, then into windows for stability tests. I like to start with super pi (yeah some folks will say BUT...) but with i7 mem controller on cpu, super pi isn't a bad place to start at. I've experienced an hour blend prime95 stable only to not be able to even pass 2nd loop of super pi 32m before with i7 920/x58. Of course do both tests etc.

Yeah i found the right cpu vtt volts allow me to clock cpu higher with less vcore as well

i started to try push to 4.0ghz but i have problem to stabilize, i put 1.38 cpu vid and 1.48 cpu vtt, anyone knows how put more volt on nb?
this voltage its a pretty high to 4.0 or its ok, my temps its 33 in cores idle and 54c load. with 1.35vid and 1.42vtt in 3.8ghz
for cpu clocking NB doesn't play much part in i7 920 anymore. Key volts are vcore (vid), cpu vtt (uncore) and vdimm (memory volts).
