MAM or Turbo on P4P800E Deluxe?

I have a new P4P800E-Deluxe with bios 1006. I found that I can set
either the Performance Mode to "Turbo" or the Memory Acceleration Mode
to "Enabled" and the computer works fine.

However, if they are both set this way at the same time, the computer
just keeps rebooting when it gets to the Windows XP loading screen.
Any thoughts on which one would give me the biggest benefit?

I am using 1 GB of Corsair TwinX XMS 2 2 2 5 memory set to 2.5 2 2 5.
Would changing the timing make a difference in getting both of these
options to work at the same time?

AFAIK, Turbo forces the CAS setting to 2. At least it has in past
cases. You can verify the settings in Windows with CPUZ or some
other tool.

I would think MAM plus your choice of manual memory settings,
would be all that is necessary. Fortunately, this chipset is
designed properly, and is not upset by running in dual
channel mode. I would not expect the Northbridge to care
whether you run it in single or dual channel mode.

Are you giving the DIMMs more than stock voltage ? That might
help them to achieve their rated speed. You should verify the
memory, using at least memtest86+ (memtest.org). That is better
than crashing WinXP over and over again, to find the best RAM
settings.

If you overclock and you're going to turn this feature on make sure you
don't use the Intel SATA, only the Promise controller. You'll get serious
data corruption. Anything over 200SFB with MAM causes corruption of data on
drives connected to ICH5R controllers. If it's a RAID 0 or 1 array, you'll
lose data slowly but steadily. Been there, done that :-) If you lock the
PCI/AGP bus, overclock and use the Promise controller everything should be
ok. If anyone has more detailed info please post it. Thanks
