Is 400MHz FSB easily achievable on P5B deluxe?

E6300 on P5B deluxe...

Are people having difficulties maintaining stability at 400 FSB for the E6300 with stock heatsink?

The question is for what speed of RAM. I like to run at 1:1 ratio.
Is 400FSB is readily achievable then I will get DDR2 800MHz RAM.
Otherwise I will save some money and buy DDR2 667MHz RAM to only OC to 333FSB.

cheers.

400 is easy for me with my 667 ram

but that is not at 1:1 ratio...

If found a new bios for my P5W DH Deluxe lastnight. It allows me to underclock my CPU by changing the multiplyer. I read that the PB5 can do this already so this may work well for you.

Here is what I did. I boosted my FSB to 400 so that my ram would run at 800. I changed the VCORE from 1.3v (stock) to 1.38v. I set the PCI-E to 100 and the PCI to 33. I set the ram to run at 800 and everything else was left on Auto.

I also disabled hyperpath3 and DRAM Thottling left the DRAM Timings on auto.

Orthos reports the CPU speed wrong for some reason when the multiplyer is lowered.

why not? my ram easily overclocks to ddr2-800 which is 1:1 when my fsb is overclocked to 400
