I've had this setup running this way for a long time... p4 2.4c @ 3ghz, and the ram refuses to go over 166/333 no matter the settings on this p4c800 deluxe board. What I'm wondering is if this setup is taking a huge performance loss because of the enormous asynch that it is running in and what I should do about it. I've considered going with a 2.8c so that the fsb would lower and mem wouldn't be as bad, but I'd still need the ram to do 215 to get synched at 3ghz. Bios is updated, everything seems normal and this ram did 204fsb on my old nforce2 board so I'm at a loss. The question basically is how bad is this asynch overclock hurting my performance and what's the best route to fix it if I do need to do something about it.
