Adjusted CPU FSB clock- did I kill my PC

🙁

Hi - I have just installed an AMD Athlon XP 3000+ 333mhz FSB CPU
motherboard: MSI KT4V
motherboard bios.. not known..updated by flash 9.5.05
heatsink brand - supplied with Processor in Box by AMD
Operating system: windows 2000
The problem:
I bought the new processor this week and installed it yesterday 9th May 2005. The PC restarted fine.
Then I upgraded the bios from MSI website - no problems and the PC restarted fine.
Today I went into the bios setup, and changed the CPU FSB clock, which was on 100mhz to its maximum 280 mhz
The PC will not restart.. the HDD light comes on constant...the monitor says its getting no signal, and windows does not start. nothing starts. the PC will not start from a floppy rescue disk or go into safe mode. It just sits there with the HDD light permanently on.
I fear.... I may have accidentally types in 2800 instead of 280 Mhz in the bios setup CPU FSB clock setting.....
My question is this...
1- have I fried the AMD chip ?
2 -how can I reset the CPU FSB - so if i put the old chip back in or buy another THAT wont get fried too?
Please can you help me

While I don't think almost tripling the FSB frequency without adjusting any other setting is a good idea, the CPU is likely not fried. Try resetting the bios according to your motherboard manual. It is usally about setting a jumper, waiting a few seconds, and then resetting the jumper.

If this gets you back to normal, I would encourage you to read one of the many overclocking guides on the internet before trying again.
 
find the reset jumper on your motherboard and use it. You probably didnt fry the CPU, but 280FSB is WAAAYYYY to high.
 
your default cpu speed is 166mhz,did you try to get 333 but the mobo stopped at only 280? lol.

166mhz = 333 ddr. so after you reset your bios to default go back in the bios & set your fsb to 166.
 
Right - thanks to all for being soooo prompt... am using laptop to write this... but about to unplug desktop and try reseting as described... thanks again.. will post soon as it has all worked (fingers crossed)

lmfao!!! oh hell, i think i'm scaring my kids, THATS how hard i'm laughing at that sentence!! 😀
 

Da...Daaaaaaa



I am back.. this is the desktop born again ..risen from the dead etc etc...

Reseting by moving the jumper did the trick ..as they say...easy when you know how...so thanks for showing me.

All my life (am now 43) through fixing cars, renovating houses, and nowadays computers... I find scarey moments like tonight... and they with help from people who have gone before (in Karate Sensei does not mean master or instructor, it means means "he who has gone before")..

You all have helped give me that thrill of beng able to fix something... from fitting brake discs, to plumbing a bathroom, and more... I guess you all know what that thrill is like when it works!!!

cheers... and all the best, friends

LOL Good news🙂 Might I suggest just go into Bios and select "load optimized defaults" and hit F10 select Y and it will exit. This all you need until you read up about Athlon Xp overclcoking and bios settings. 280FSB is crazy and dagerous in those mobos😛

If you have specific questions LMK🙂
