I need professional overclockers help!

[survivor]

hi
ı just changed my mobo and cpu. I worked on it last night and ı am a little disappointed. I am stucked at 240*11:2640 couln't go further . Infact it starts at 250*11:2750 with no problem and can get super pi 1M:30seconds but it gives error after just one minute when ı start prime 95 blend test. all the way back from 250 to 240 are the same. I did not have much time so ı could not wait longer but it worked without any error for 36 minutes at 240*11:2640 then I stopped it and went to bed. (super pi:31second) do u think it is the limit of my cpu? it can't be the ram because it was working fine at ddr500 with my old rig and also ı tried lowering the ram but it did not work. summary of my current settings are:

cpu : 240*11:2640 1.5 volt
ram:ddr480@240 mhz 2.6 volt (overvoltage did not help)
nf4 voltage:1.5 htt voltage:1.25
temps: idle:32 load:46

Is there any way that ı can run my cpu faster or is it the end?

try 260*10, the ram should be ok but try relaxing the timings a bit. i wouldnt up the cpu voltage anymore, what kind of RAM do you have, i have my voltage on the ram at 2.75v, corsair.

EDIT

just read that kingston runs at 2.5v, so nevermind also just read several reports its not good at overclocking anymore apparantly it used to be. i can get my Corsair all the way up to 235(470) prime stable( 5 hours) without increasing the voltage.
