Just wanted to know that before the boards with lockable agp/pci frequencies was it possible to actually damage ide devices such as hard drives and cd roms ect.....refering to the logic boards in the devices from running to high of a frequency. Refering back for example a fsb of 148/42 ect..... If so could someone explain how or why this happens.

normally u just get a failure. however iguess runnin anything outta spec could concievably damage or destroy it due to heat, bearing wear etc..

Well just about all the drives ect... I have had fail was the logic board in the device ie cdroms, hds, ect..... Since the IDE controller is on the same bus as the pci I was wondering if the high frequency resulted in the damage to that component.

boards with lockable pci/agp will give a perfect 33/66mhz to each part in the loop.

therefore it would be the same as if you were running at stock speeds and your drives, etc would be free from overclock and thus problems.

It happens because the PCI devices (such as onboard IDE controllers) are designed to run at 33 MHz. Running them faster, puts more demand on the devices, and they won't all respond in the same way either. One device may be fine at say 39 MHz, while anothers circuitry can't handle it and begins to malfunction. The most likely result from what I've seen is data corruption and system instability, though I'm sure permanent damage could be caused as well in some circumstances. Especially over an extended period of time.
