You rather lost me on your first post, if i understand correctly you can boot @ 260 but you can't load into windows? Same thing happens @250
Have you tried lowering the ram timings?

I don't know if it can helps but you can always try to add some heatsinks on the mosfets and southbridge
And do a vdd mod (i'm kididng of course!)

ps can you load into windows? and is stable and fast under it? i mean maybe it takes a long time to boot but if you're patient you can boot
Hehe, this is not a RAM issue. My RAM can do 260FSB just fine. The issue at hand is high fsb & high vcore together...

Anyway, disabling APIC solved it, but now my 3dmark scores have tanked. So I'm back to square 1.
