I used to have a DS3L and manage to get my E2140 Orthos stable at 435x8. However after switching to IP35 Pro, I can't even pass the 429FSB mark even I increased the MCH and ICHIO.

Any ideas what I missed out? There are indeed plenty of stuffs to configure in the BIOS and I don't raelly know what to add. I tried adding all but same thing.
