Guys, please bear with me if I'm asking a question thats already been covered previously but I'm at page 26 in this thread & no where near 1/2 way though the X38 thread!

Thanks to Clunk & Praz for their help so far, even if their comments wasnt aimed directly at me

I am struggling to get an FSB of 435 that is OCCT stable (very large). The longest my rig has gone before locking up is 15mins

I am a recent convert to DFI boards as those fine guys at Scan are stocking them now, until then DFI wasnt really an option for me.

I've posted my most stable BIOS settings below

One thing of concern coming from the Maximus Formula is the increased volts I'm having to put through my NB, I though 1.45v was high on the MF

I'll be putting my NB under water this weekend when I get the time & the block gets delivered, until then I'm using the bundled HSF with an 80mm fan blowing though it; the highest I've seen the NB get to is 41deg. My system temps as indicated by SG are in the region of 55deg at their highest. Are these acceptable?

Anyhoo, thoughts on what I can do to get past this nightmare 435MHz are appreciated.

Note: Ram timings & settings are low, I'm just chasing a max FSB for the time being.
