Abit AV8, memory settings for 4x256 of memory

[lunaismoon]

Abit AV8 VIA K8T800 Pro
AMD 3200+
corsair twinX dual channel 3200

CPU-Z Memory Slot info:

Slot #1 CMX256-A-3200C2 Corsair
Slot #2 CMX256-A-3200C2 Corsair
Slot #3 CMX256-A-3200
Slot #4 CMX256-A-3200

I'd like to know the correct settings to getting this Mobo to see all 4 slots of the above memory please. Or any info. I've spent all day reading various message boards to no avail. I've tried some BIOS changes ( changing from 400 to 333, changing from 1T to 2T) and they haven't worked so I may not be reading the right information. I'm looking for a definitive answers (maybe my two sets are not compatible? but they were on my last P4 system) Thanks.

What exactly happens there?

One suggestion is to move the DIMMs in slots 1&2 to slots 3&4, and the ones in 3&4 to 1&2.

Have you tested both pairs individually?
