I have replaced my motherboard with this motherboard Gigabyte GA-P43-ES3G,and installed old processor Intel Pentium D 945, 3.4 GHz Dual Core Processor and 2 ram hard disk everything. After installing fresh windows and motherboard drivers everything has become bit laggy comparing to my old motherboard which is a really older one gigabyte GA-945PL-S3 Someone suggested me to check your FSB AND BUS speed how do i do that. currently this is my buss speed and FSB as i think http://valid.canardpc.com/show_oc.p...

i have Geforce 7600gs with proper drivers installed

There's nothing wrong with the bus speed. The multiplier is incorrect. The D 945 is supposed to be clocked at 17 x 200MHz...you have it at 12 x 200MHz.

mate how do i correct it?

Go into the BIOS & change it. EDIT: I just thought of something. You probably have SpeedStep (CPU EIST) enabled. If that's the case, the multiplier will vary depending on load. This is done to keep the CPU temp down & lower the energy consumption. At times (especially at idle/no load conditions), the CPU is probably running at an even lower clock speed....1.2GHz (6 x 200Mhz) for example. If you disable CPU EIST, the CPU will run at full speed at all times. You must have taken the info in your link during medium load conditions?

actually You are right now i m extracting some files with winrar and it has reached 17x,so what do u suggest what should i do to fix this lag??? could it be any sort of ram problem?

I suggest you read Response Number 4 again; namely "You probably have SpeedStep (CPU EIST) enabled. If that's the case, the multiplier will vary depending on load. This is done to keep the CPU temp down & lower the energy consumption. At times (especially at idle/no load conditions), the CPU is probably running at an even lower clock speed....1.2GHz (6 x 200Mhz) for example.
