New to O/C :Pentium D 805 - Page 4

post #31 of 34
Thread Starter 
yup, that makes perfect sense to me now. I didn't lock anything, i just upped my frequency *which is believe is the same as fsb* so that automatically changed other variables causing my corrupted windows. so i'm guessing for attempt #2 i should lock the ram and pci bus THEN up the fsb.

Most ECS Elitegroup boards don't have a locked PCI bus. You need another board designed for overclocking rather than a budget board. I've got my FSb up to 246 but after that the PCI bus goes too high and it won't post.

Its like your CPU having a rounding error in prime95 when you clock too high only on your SATA controller, if that makes sense?
It's a good thing my title is 'Overclocker In Training' because I had never heard of this until now. My PCI bus is locked steady at the default and does not move when overclocking using 3rd party software (whcih my only option) so I should be fine. When I do my next upgrade to a good overclocking motherboard I'll ensure that the PCI bus is locked there as well.

There can still be problems. That why some extreme overclockers only use IDE drives because SATA controllers just cause extra hassle.
