OC limit with S3/e6300

[tomtbone]

Hey all, here is my setup:
Gigabyte 965p S3
e6300
Ballistix DDR2 1GB (2x512mb)

I can only get up to a 420 FSB nothing higher. When I do, I can't boot into Windows. Other Specs:
Voltage: 1.35v on CPU
+2 on MCH and FSB
+3 on VDIMM
Memory timing is at 5-5-5-15

How can I get this higher? I have everything else disabled too as far as limiters go. While writing this the CPU temp is at 27C.

Any help as to where I can go from here?

What version of bios do you have? What memory speed are those ballistix? There is an intel overclocking database in the Intel forum in case you dont know.

I have the newest F6 bio and the Balistix is 800.
