why is my bus speed at 133 mhz?

[leanvaio]

it should be running at 533 mhz and it is running at 133mhz i cant find any settings in the bios

Re: why is my bus speed at 133 mhz?

Given that you didn't think we needed any sort of system information, I can only assume you're talking about an older Pentium 4 system using a "quad-pumped" front side bus. Since memory of that era could not even theoretically run at a speed of 533MHz, the system took the default FSB of 133MHz and quadrupled the data path internally, giving this pathway a speed of 533MHz for internal communications. If this is not the type system you have, then it would be useful to include some basic system specs.

its a pentium m at 1.8 can u tell me now?

Re: why is my bus speed at 133 mhz?

to be more precise its a pentium m 750 and it on the manual it says that it runs at 533mhz but nero info tool shows that it runs at 133, is this right or not?

All socket 478 and 775 Pentium 4s (and P4 Celerons) and all Pentium Ms (and Celeron-Ms) are quad-pumped, which means the overall bus speed (533MHz, here) will be four times the FSB (133MHz). So yes, it's fine.
