Does the P5K support a 1:1 memory divider?

I'm thinking of doing a mild overclock to my E6550, bringing it up to 2.8GHz (400x7). I have DDR2-800 RAM which would run great if I could to 1:1 (400MHz). Of course, all the DRAM settings are shown as memory speeds (DDR2-667, DDR2-1066, etc.) so which one do I pick for a 1:1 setting?
 
Since its based on the same chipset as the IP35, use the 667 speed setting, that is 1:1.
 
If I understand, to get 1:1 on P35 boards, I should set the DDR2 speed which is exactly double of the FSB or very close.

 
the lowest divider my P35 board has is 1:1 so if I set 400FSB I need to run my ram at least at 800mhz which is DDR800 or PC6400, some baords have DDR set eg 400FSB gives ( DDR800, DDR1066,...), gigabyte gives actual ram speeds, just work with the ram multi there to obtain the speed you want, but again the lowest divider is 1:1 so you cannot run FSB at 400 and ram at 667 like with eg the Nvidiots chipset...

I have a P5K myself. If you want an absolute 1:1 FSB:RAM ratio with that E6550 (FSB1333) on that P5K, you'll need to run the memory at DDR2-667 speed. This way, both the processor's FSB and the memory would then be running at the same actual clock speed. Or, if you do overclock the FSB to an effective FSB1600, then DDR2-800 (PC2-6400) memory running at its rated clock speed would result in the absolute 1:1 divider.
 
I have pretty much the same setup as the OP and I hit an FSB wall at 486 with my E6550+P5K. I'd be interested to know what the OP can do on his setup. :)
