FSB : DDR 400 == 800 Mhz ?

[vivek]

Hello

Can someone explain the difference between the DDR 400 FSB (nForce2) and the 800 Mhz (i875P / i865PE) with regards to the FSB ? Is the bus speed of both the chipsets the same i.e. DDR 400 == 800 Mhz (of i875P) ?

Thank you
Regards
Vivek

200Mhz double pumped vs 200Mhz quad pumped.

I'll leave it up to you to figure out which goes with which.

Athlon Xp processors use DDR
P4 uses Quad pumped.
There was 400,533 FSB sor the P4, Quad pumped
For the athlon XP 266,333 and 400, DDR
It't not dual pumped it is DDR, which is very efficient compared to the quad pumped sh&t of intel.
