2GBHZ and AW9D-MAX at 401fsb 4:5

[Prelector]

Trying to OC my 6400-2GBHZ a bit, and can't seem to get the system to post on new settings:

CPU: e6400
FSB: 401
VCore: 1.35v
VMCH: 1.6v
VDimm: 2.35v to 2.45v
Divider: 4:5
Effective RAM speed: 501x2 (1002mhz)
Timings: 5-5-5-15-40 and 6-6-6-18-40

I've seen reviews of others getting up to 1066 on the 6400HZ, so wondering where my limiter is: Ram sticks themselves not capable, or a setting somewhere?

Tried upping vdimm from 2.1 (stock running) to 2.35 and even up to 2.45, no go...
Tried loosening timings from 4-4-4-10-16 (stock running) to 5-5-5-15 and even up to 6-6-6-18, no go...

Nothing I've tried even gets the system to post.

Anyone have any thoughts, suggestions?

Managed to get up and running 4:5 415 FSB 2.3 vdimm, with one stick okay on the AW9D max, but won't even boot with two sticks. Needs more juice maybe?

Whatever, have gone back to 1:1 420 FSB
