Trying to OC Phenom II 925 above FSB of 260 mhz

I've been fiddling around with Overclocking for a while now, and i've finally reached a HT Ref clock of 260mhz.
I'm trying to get a little higher, but when i increase from 260 to 265 i get BSOD.
I'm using DDR2 (pc2-5300 333mhz)
My temps are around 50C (70 is danger zone for my cpu)
My ram is stable (timing of 5-5-5-15) (tRC=20)
Also my NB speed is around 2000ghz, and is matching my hyperthreading speed.
Voltages are as follows.
CPU Voltage=1.440 (original 1.3)
Ram voltage is 1.9 (1.8 original)
NB Core= 1.2

I'm using a stock fan (Though temps are fine)

What settings should i alter to get to Ht ref of 265, or even 270?
Thanks! :)  Just tell me if i'm missing anything! :p

Dangerous when rise fsb too high cannot stabe, if you cpu too hot can damage, if you wan't more higher clock get good cooler after market like hyper 212 (low cost)
.
- disabled c1e,cool n quite, spread spectrum.
- when use stock cooler disabled smart fan

I see your problem not enough power voltege and timing Ram. The ram can increase up too 2.1v but depend your ram, lossen timming to 6-6-6 or 5-6-6 if strong. When rise fsb the frequency auto up.
Better way get back to 260 if still love stock cooler.

SOunds like the board is probably maxed at 260 fsb bus


this right here, though if it makes you feel any better my board only lets me get to 240-250 range

My temps are around 50C (70 is danger zone for my cpu)

70 is the max but almost all Phenom II dont like heat the coolder the better

My ram is stable (timing of 5-5-5-15) (tRC=20)

as your Ref clock goes up so doese your Ram Ratio try to loosen up your timings can stop BOSD

Also my NB speed is around 2000ghz, and is matching my hyperthreading speed.
Voltages are as follows.
CPU Voltage=1.440 (original 1.3)
Ram voltage is 1.9 (1.8 original)
NB Core= 1.2

Try upping your CPU - NB voltage which usually helps stability alot do not go over 1.35v voltage helps a lot with stabling OC more than almost anything but will always bring more heat

This is what im running atm but im still tweaking to get lower volts and temps and stay stable though I do have a XPS 240 watercooling kit helping with temps http://valid.canardpc.com/cache/banner/1731820.png

Thanks for the advice! :p  I'll try that soon (once i get my new video card)
