P4P800 Deluxe - Dual channel but linear mode?

I just put two identical DDR400 RAM into a P4P800 Deluxe board. On
boot-up, it says "Front side bus 400, Dual Channel, Linear mode" Is
that how it's supposed to be? I'm thinking since it does two thing at
once, maybe it should be in parallel mode. Just want to double-check
with experts here.

Yup, that's good. To be sure, you can run the memory read benchmark
that is part of Everest.exe (from Lavalys, Inc.). If you get anything
near the advertised peak 6.4 GB/s, then the RAM is configured correctly.

I just saw 5314 MB/s on reads and 1808 MB/s on writes on my P4C800-E,
with a pair of CL-3 ECC DRAM sticks in dual-channel mode. I might be
able to do a bit better by running closer to standalone, since Everest
shares the hardware with other apps -- turning on Prime95, even at low
priority, lowers the reported memory R/W performance by ~25-30%.
