i first thought the cpu or mobo doesnīt like high multis. but right now iīm 20mins into prime on 200x18.5/2.6ghzNB with 1.4875v/1.4vNB with my ram on the 1066divider. almost the same settings as in the screenshot in my sig only higher ram and nb speed.
itīs really funny that with phenomII u have to disable all the stuff that increased performance on phenomI.
cpu tweak is the most important. with cpu tweak enabled i canīt even get 3.4ghz stable. cpu prefetch is also disabled, as i donīt really know what itīs doing and it doesnīt help with performance.
both the ht and pcie-core volts are upped to 1.28V
cpu vdd is at 2.8V

4ghz is still a no go. maybe it has something to do with the sb750, as it always craps out when itīs trying to acces the hardisks (raid0 array).
but thatīs still a long way to that magic 4. first i got to get 3.8ghz stable which always gives me irql_not_less_or_equal or other ram related bluescreens after a few minutes of prime.

have you tried something like this,,






NOTE:
my 9950 on the Asus 79-T using 13.5x263 and 800ram divider..

Of course if you use the 14.5xCPU multi it would = 3.818ghz...you never Know . it just may like a 14x 14.5 or even a 15x using the 800ram divider. Dont pay attention to my Voltage,, Yours will be way lower @ 3.8 on a PH2.
