Yeah!
mem settings didn't help me to get higher HTT but damn it gave me 100mhz more. Before 10x240 was last stable when running pifast & super pi,
now 10x250

(and it wasn't coz of mems)
So 3-4-4-8 2T really helps with CPU
asked this on other thread too,
-does chipset voltage make any difference? (now 1.65)
-does cpu setting 'normal' or 'fastest' make any diff to
oc or performance?
