Memory Timings set according to Overclocking?

Hello,
my system:

Board: P5Q Deluxe
CPU: Q9450
Memory: 4x 1GB PC2-6400 (OCZ2T800C31G)


Now I have the Q9450 at 3.2 GHz at FSB overclocked, also running as far as stable. With the ram settings to auto run the memory at 5-5-5-15 at 800Mhz clock set (1:1).
When I transfer the settings from Auto to the specified settings of the memory settings run manually it is simply not stable.

by OCZ are:
3-4-4-15 at 2.3V

where is the error? or is it no longer possible with the memory timings to drive?

hi,
you could change the memory controller with voltage.

hi,
because the bios by default reads values from the SPD profile,my ADATA's running 100% stable at 4-4-4-11 2T @ 800 mhz / 2.0 v

Hi,

Please try the following settings: RAM 2,2 V, NB / MCH 1.4 V, Ai Clock Twister Lighter / Light, CPU and PCIE Spread Spectrum Disabled, 4-4-4-15 timings and Row Refresh Cycle Time is 58 If the current BIOS version?
