I got it to 3.83ghz with a vcore of 1.31 at around 275 fsb anything higher i have to bump up the vcore, when i go to 300 fsb i get all these artifacts

why?

I don't think the chipset can cause artifacting when overclocking.

Can you reduce the multiplier on your current CPU? You might be at the top MHz your CPU can handle.

Though, it is rare I see 920's not going FAR above 3.2 GHz.

I ran the extreme power supply calculator last night on mine and it shows 483 watts required.

My 920 is OC to 4ghz at 1.38 vcore and 2.2v on the ram. Mine wont get stable at 300 but I've never seen artifacts from anything i've done on overclocking the cpu or ram. I've only seen artifacts form OC on the GPU.

So you might be pushing over the edge on power. Not sure. Run this calculator.

Lock the PCI to 33.33mhz and the PCI-Ex16 to 100.

Some people also had success running the PCI-E a few MHz above stock specs. I'm guess max 109 MHz for it, and even that is pushing it.
