At the moment I have a gigabyte via kt400 7VAXP with 2 sticks of 256 ddr 400. It doesn't perform well with them and won't run them at DDR 400, only ddr 266. I do however use the Promise RAID 20276 chip. Would you guys be prepared to sacrifice RAID 0 for serial ATA and the dual ddr memory controllers of the nforce chipsets? I might just hang on for an nforce serial ata raid chip, serial ata raid does exist but i can't remember for the life of me which manufacturer makes that board. I just really like the look of peak 6gb memory bandwidths, thats faster than rd 1066 isnt it?
