FSB question

Discussion in 'General Hardware' started by PlagueWielder, Apr 21, 2003.

  1. Hey

    My mobo has a 266 MHz FSB and I have a 1 GHz T-Bird. In CPU-z it says that my FSB is 132.5 MHz and my bus speed is 265.1 MHz.

    So my is whats the FSB speed? Is it 133 or 266?

    Thanks

    its 133 x 2 =266

    like 166 x 2 =333

    get it? :)
     
  3. so my FSB is really 266 MHz?

    why X 2 though?

    see like me I am overclocked

    its spose to be (133x11.5)X2=1529.5 ghz = athlon 1800+
    but its set to (140x12.5)x2=1750.0 ghz = athlon 2100+


    everything follows the fsb my ram is also on the 140x2 = 280 mhz

    so if you use a cpu with a 266 fsb your gonna be better for overclocking with ram that is 333 ( ddr2700 ) cause that ram will allow higher MHZ more than the ddr 2100 = 266 mhz


    hope that cleared that up a little :)
     
  5. Ok thanks, I got a little bit worried when I saw that CPU-z said that my FSB speed was 133 cause I have a Compaq and I cant really change anything in my BIOS.

    your true front side bus clock for the cpu is 133mhz... the double data rate marketing speed becomes 266mhz... x2 :)

    like kermit said..

    Double data rate on the AMD:s. 133x2 = 266
    Quadruple on the Intel:s. 133x4 = 532 (533)
