In a week they response to me to try a new BIOS: F5d. The problem continues but I have a huge improvement in memory performance in Everest with this new BIOS.

With F3 I had 8600 and now, with F5d I have 9500

Anyone know why bios shows AHCI BIOS Not Installed ???

Thanks !
Hi Yenclas,

I have the P35-DS4 too, can you share me that bios with that nice performance memory boost?

My board comes with F4 bios and now I am in F5C bios but my memory performance is very low. With DFI 965 with same settings I scored more...

Can you try with that settings?

CPU at 8x400 -> Q6600
RAM at 1:1 (2.0 in GA) 4-3-3-10 -> 4GB mushkin XP2-6400

In sandra and Vista x64 my memory bandwith is 6700 mb/s.

Thanks in advance
