Overclocking Asus P5B Deluxe versus abit IP35 Pro

Exactly what you don't want to do. By setting your memory to run
at its rated speed from the start, you are removing all the overclocking
headroom for which you bought the faster RAM. With your RAM set
at DDR2-800 in the bios, increasing the CPU Frequency to 333 MHz
results in trying to run your DDR2-800 at DDR2-1000 speed.

Instead, if you set the memory to run at DDR2-533, at a CPU Frequency
of 333 MHz, the RAM will then be running at DDR2-667, which is within
it's capability.

This must somehow makes sense to Chinese people, but the rest of us
would be happier with a setting called "FSBRAM Ratio," which we
could just set to 1:1.

Thanks for the info. I guess that makes sense. I'm a slow learner - and I
did not read the fine print in the P5B Deluxe Manual. Where I got in
trouble is the abit IP35 Pro let me change the Frequency to 400 without
changing anything else. However, that was with an E6750 which has a lower
multiplier to begin with and apparently the P35 chip is a better memory
handler.
