ACHI mode does not really work with the SB600 (some BIOS on certain boards even remove the option). According to that review, the new SB still has issues with AHCI, so I think that's why they did not use it. AMD hyped this SB750 so much that I'm rather disappointed; the "extra overclocking" seems more like a gimmick as well.Last edited by Melcar; 09 August 2008, 10:07 PM.

I can't get the bonnie++ tets to run properly, so here is a run with iozone. SB600 with a single SATAII HDD:
Someone has a competing Intel/nvidia solution to compare to?
