P4C800e deluxe and overclocking the memory

All,

I put together a new system with ASUS P4C800ED and OCZ Platinum PC 3500 512
MB (2x) rated at 433mhz 2-2-3-6.
After a few times trying to increase the parameters manually for
over-clocking, decided to use the AI overclocking (by percentage) that the
jumperless option allows. I was able to overclock 5%, 10%, 20% and
each time I used Sisoft Sandra to measure the memory performance the DDR
memory speed
drops from 400 MHz to 266 or 288 MHz, resulting in reduced memory
performance. I tried manual setting but it won't boot.

Any ideas?. Is there a list of manual parameters that correspond to the
above % values that will work as a set?. I appreciate any
suggestions/recommendations. I would simply like to run the memory to his
stock speed at 433mhz and 2-2-3-6

Thanks

At default speed P4 3.0c the memory timing are 2-2-2-5 and run fine at
400mhz

Funny how with AI Overclocking one ends up with an underperforming computer. Use the manual settings, and
change the DRAM Frequency from [AUTO] to [400MHZ], then up the FSB speed to however much you want. 216 gives
3.25GHz. In Advanced->Chipset, Performance Acceleration should be [Enabled], and Spread Spectrum must be
[disabled]. With Spread Spectrum enabled on my system I can only set the FSB to 201Mhz max while the DDR runs
at 400MHz.
