Hi,
I have an HP/Compaq SR2150NX w/ ECS RC415ST-HM motherboard. MB is said to accept Pent D 9XX series CPUs. I replaced my Celeron D 356 533 Mhz FSB w/ Pent D 950 dual-core 800 Mhz FSB. Memory is maxed out @ 2Ghz w/ DDR2 pc-4200 533Mhz.

I've done "msconfig" to enable 2nd cpu core, but apps still run slower with D 950 than they did w/ Celeron D. Help!
