BSOD when overclocked?!

heres the deal...
i had to reinstall my OS last night and i got everything installed while the computer was running at default settings in the BIOS so nothing is overclocked. so my current settings are RAM is at the speeds of the SPD chip and the FSB is at 200Mhz x 4 = 800Mhz and the CPU is running at 2.6Ghz. everything runs fine and i can do whatever i want while the computer is at default settings. when i overclock i have my FSB at 250Mhz which in turn causes the CPU to operate at 3.25Ghz and i have PC4000 corsair XMS series RAM(rig in sig for reference). the second i overclock anything i get a BSOD and a slap in the face. i can get to the logon screen and try to log into my account. i get the BSOD when the computer is loading my configuration settings. i have no clue whats going on. i am using the RAID array for the OS and i have a second harddrive on the IDE channel for doing images of my boot partition. if you guys can help me out then im am asking you while on my knees(yea yea dont get any ideas :rolleyes: ).
thnx for any input. :D
 
sounds like your overclocking your pci bus as well ?
when you bump up the fsb you want to make sure pci bus stays at 33mhz
 
i forgot to mention that i locked the PCI/AGP bus. i can set it to auto or to a certain frequency. right now its set to 33.3/66.6 (PCI/AGP).
 
vcore volts? you might need to increase them.

You might just be pushing your CPU too far. Most 2.6C's would do around 3.0-3.4+ You might have a "dud" that only does 3.0Ghz. Have you gradually worked your way up and tested for stability. If you can boot, and get to log in. You're very close to being stable. You might need to back down to 240FSB.

Also, what type of mobo? does it have PAT, GAT settings, etc.... you might need to disable them.
 
ive been running this system at 3.2Ghz for about a year now and havent had a prolem. i reinstalled windows XP pro last night and im getting slapped in the face with the BSOD now. unhooking the IDE hard drive doesn help. trying to overclock just the littlest bit causes it to BSOD. i could have messed up my RAM somehow but i doubt that. i will run a session of memtest86 in a bit after i get some other stuff done. i know its not the RAM because how come i can play games and use the computer without a problem but once its overclocked even a little bit it gives me crap. i dont know. maybe i should sell my comp and build a new one. maybe maybe. OR i can go and buy a 3.2E P4 CPU and use that so that way i can at least have a 3.2Ghz speed CPU like i used to and have more L2 cache so my performance will be a bit better instead of using this 2.6Ghz at stock speeds. if i figure this out then ill keep it. if not then im buying a new CPU.
 
don't buy the 3.2E, the 3.0C is cheaper and will OC more... you'd probably get 3.5++Ghz with one of those. The 2.6C's were kinda sucky OC'rs in general for some reason.

My guess is you changed something, somewhere. Did you clear CMOS? update BIOS? or change any other settings? You just need to meticulously go through and check every bios setting, and trouble shoot.
 
well guys thnx for the help but i fixed it. i just put the Vdimm voltage from 2.65v to 2.75v and it booted without a problem. makes me laugh pretty hard how it was an obvious thing and such a minor thing that causes the whole system to become unstable. well thnx for all your time and effort.

I guess you followed my instructions...? you're welcome :)
 
well what i did to find the issue was just break it down. usually if you get the BSOD then most likely it is a hardware issue(most of the time for me anyways). i just narrowed it down to the CPU, RAM, or bad harddrives. i found that non of my hardware was bad because i could run everything extremely stabley at factory settings. so i just overclocked my comp again to see just exactly what was going on. so i while i had everything set to the overclocked settings i slowly raised my voltages at the same time until i was able to boot and then i kept going until i was able to run windows and play games like a champ :D. i couldnt be happier. thnx for all of your time though.


PS: i love you guys! :D
