Overclocked P4B533 + USB stability?

[diehlr]

I remember reading about some Asus boards having stability problems when using USB and overclocking beyond a certain point. Does anyone know if the P4B533 boards have this issue? I have a USB mouse + printer + webcam and would like to use onboard USB if possible. Thanks.

USB stability issues will be present on any motherboard when overclocking excessively. The reasonn for this is that the PCI bus is run further and further out of spec the higher the FSB goes. USB runs on the PCI bus for now. I have an ASUS P4S533 and stability issues arise all around iff the FSB goes around 140. Your best bet is to get a 1.6a and the run the FSB at 133 instead of 100 which is within spec. Your PCI and AGP busses and therefore alal of the devices on them will be completelly stable. Running those busses above spec endangers yourr devices, both internal and external. Don't do it.

Just get a board like the epox 4bda, 4bda2+ and their newer i845e and g chipsets that have locks for the agp/pci....I run 166fsb and the board locked the agp/pc to 66/33 spec from the beginnig....

I have no issues with usb devices hooked in at bootup or running...multiple usb devices....

Never fear...Boards that do not offer this, just go figure that are not good overclocker boards, period.....

That sounds fine too. Whatever you do, don't run your PCI or AGP busses out of spec. I lost an Audigy Platinum because of that (yeah for warranties)

No USB issues here either on an overclocked 4BDA2+. PCI/AGP locked @ 33/66. Everything is in spec. I have USB scanner, printer, mouse, webcam, CF reader.

i own a p4b533 with a 1.6A@2.4, the pci:agp beeing locked at 33/66 no problems encountered since. I use an usb mouse, an usb printer and a digital camera with usb connect

P4B533-E, 1.6A @ 2.4, 8 usb devices (not all on at the same time), Prime95's for 23 hours, zero stability issues.
