hey all, I don't know why I can't overclock. okay in my bios it says that my fsb is locked at 133Mhz and the cpu ratio is 8.0X and it is also locked. I have an intel pentium 4 2.40Bghz processor. I also have 256 Sd-ram. also i can't update my bios because matsonic doesn't have any updates, is there any where i can get updates for my Ami bios that supports my mobo. I have a matsonic ms9158E mobo and here is the link for its specs: http://www.matsonic.com/ms9158e.htm also this is the specs for my mobo: Processor BUILT IN AC97 PCI AUDIO Support Socket 478 for Intel(R) Pentium(R) 4 1.5GHz~3.06GHz or faster Processor Support Intel(R) Hyper-Threading Technology CPU 400/533MHz system interface speedChipset VIA P4M266A North Bridge and VT8235 South Bridge chipsets.

your mobo is one of those oddball types, this is the first time i have heard of it... it's not advisable to use a different bios not specific to your mobo, that could cause you some hassle, possibly permanent damage or loss...it sounds unlikely that you will be able to do anything with it...your best bet would be to get a different mobo from asus,msi,epox or gigabyte..those mobo's allow you to play overclocker what else do you have? cpu what kind of memory hard drive video card

It looks like an OEM board with everything onboard in Micro format. With all the trouble you may have to go through, you'd better get another board like Tbird4point6LX97 recommended. A new board from MSI or Albatron is not expensive www.newegg.com, with a mid-tower case togehter should not be more than $140. Depending on BO or C1 stepping code of your P4 2.4B. I have pushed BO to 2.9 and C1 to 3.24 Ghz @1.75 volt. Some board may require voltage mod to get over 1.7 volt. But, it is not difficult at all in P4. Best of luck.
