Hi guyz... i recently bought a CPU 1.7Mhz 400 FSB... and i got a Asus P4t533-C motherboard. When i use program like cpuz or wcpuid... it shows that my FSB is 100?? how come?? I need help guyz. Thank you so much...

Your FSB should Read 100mhz... there is no front-side bus that operates faster than 133 MHz. reason being... AMD does what has become called "double-pumping," sending twice as much data along the bus in each clock cycle. (100mhz x 2 = 200mhz fsb.) Intel has fired back with what is being called "quad-pumping," sending four times as much data with each cycle (100mhz x 4 = 400mhz fsb). Buses are hardware paths that link a computer's microprocessor with memory chips and devices it communicates with. A front-side bus connects the CPU to main memory and to peripheral buses that run to such system components as disk drives, modems and network cards. A backside bus is a relatively high-speed link that the CPU uses to pass information to and from external cache memory, most often the Level 2 cache. Buses are frequently described by their speed, expressed in megahertz. Tank863

There are new P4 processessor which work with the higher fsb. THey use DDR ram as well. 133*4 = 533. Your P4 is older that is still working with the 100mhz bus. In order to get the 533, you have to upgrade your processor to a newer one and updrade your ram too.

Thankz Thank863 next to the 100Mhz FSB it says QDR i guess it stnads 4 times. Thankz again

Hey eric i just recently built this pc by myself. and i could use RDram pc1066 but i am only using RD ram PC800 and i got 512 Ram that ain't bad dude... And Tank863 is right i doubt that QDR stand for 4 times.
