Pentium 4 3.0GHz on pc 133 MHz board

i have old 2001 model pc which runs at pc 133 sd ram upgraded to 768 mb with Pentium 4 1.5 GHz 478 pin, my question is that if i pop 3.0GHz p4 on that board will it run properly?

  1. Possibly, depends on the specific motherboard model and which Pentium 4 processor you want to use.
  2. Depends on the board.

    right now my pc is using Pentium 4 1.5GHz/400Mhz 478 pin

    and i'm thinking to upgrade it to Pentium 4 3.0GHz/800Mhz 478 pin

    will 3.0GHz run properly? because according to BIOS info my current processor is 1500MHZ/400MHZ FSB and RAM speed is 133MHZ
  4. Take a look at your boards cpu support list. The Ram speed is of no consequence, except that the new processor will also have pc 133 ram as the memory controller is on the board. Or that might be DDR since DDR 266 is doubled from 133.

    my broad is custom built by Compaq in USA back in 2001 and till now i haven't find any info about it and also when going on bios i have very limited setting and info about my board it gives basic info about board but on procesor it sates Pentium 4 1.5GHZ with 400MHz FSB and i'm in dilemma that it will support Pentium 4 3.0GHZ with 800MHz FSB or not!
  6. Probably not if it only supports 400MHz FSB processors.
  7. but how can i find out my motherboard max FSB speed supported?
  8. The 533/800mhz bus P4's in that era required the 875P chipset. The 865 and earlier chipsets would only support 400mhz bus processors. check the chipset on the board.
    Unless you are mistaken about your boards manufacture date, I doubt if your board has the 875, as it was released in 2002.
  9. 533mhz FSB will be the max that board could use since your RAM is 133mhz but thats even if it supports the 533mhz.

    I would say that this is the max processor that might work.

    It will definitely not support 800mhz FSB since your SDRAM would not be fast enough to run its base clock speed it simply will not work.
  10. Fastest cpu I could find on HP Part Surfer is Intel Pentium 4 processor - 1.80GHz (Willamette, 400MHz front side bus, 256KB Level-2 cache, Socket 478)
