I am trying to get my CPU to 2.75-2.8, but it seems almost impossible, Here are some bios stats: FSB=300x9=2.7(stable), HT freq 3x=900, CPU core=1.65, Chipset core=1.7, DDR core=3.0, RAM is DDR 600, timings=2.5,4,4,8 stock, I cant get stable at anything above 2.7, at 2.73 and above I get a BSOD at windows startup, temps =20idle, and 50load dual P95, I'm too scared to set the CPU core any higher(ie2.75) Does anyone have any suggestions or advice?

That's probably the limit of your CPU at that vcore. Try dropping the Ram speed and retesting with a higher HTT speed to check it's not your ram that's unstable. If it is your CPU, then I wouldn't really recommend pushing it much further.
That's a decent o/c though and an extra 100Mhz won't really make much difference to real world apps.

I've retested with the FSB as high as 325, and dropping the multi to 8.5 while on a RAM divider and it wont boot to windows, any other suggestions

2.7 is an excellent overclock for that cpu....most people cant get to 2.6...so I would be happy with it.
If you want more, do as recommended before and throw a divider on and make sure only your cpu would be the cause of instability...keep your HTT multi in check also.

I always keep my HTT multi under 1000, I have already tried dividers, I am happy with 2.7 but I would be much more happy with 2.8, What is PCIE clock do, I can move it up from 100MHZ in increments of one

Does raising the chipset core do anything?

The PCI-E Freq is the speed at which the GFX communicates with the Motherboard. You can try raising this and see if your 3D apps are quicker, but with a single card this is very unlikely to do anything other than make your card hotter.

Raising the Chipset and LDT voltage can aid stability at high HTT levels. Bump them up a notch and test, but I doubt these are the problem.

then you should have got the 165 opty. better chance of hitting those numbers, and clock for clock the opty would have outperformed your x2 3800 at the same speeds by far.
