Can OC cause USB problems?

[v3rax]

I play Call of Duty 4 and have been having problems with my keyboard and mouse acting wierd. What happens is that certain movements that I have bound to my keyboard or mouse quit working. For instance, my key for "aiming down the site" is my right mouse button. I will be playing the game on a server and all is well, then all of a sudden, I cant aim down the site, and soem of my movements on the keyboard stop working too.

I have a Saitek USB keyboard and a Logitech G5 USB mouse. I have the latest drivers installed and have re-installed all drivers and even reformatted. Nothing helps.

I am just wondering if the fact that I have my CPU OC to 3.2ghz is causing USB problems?

Anyone have any ideas?

it may be an issue with an overclock, i'd try to raise the ICH(southbridge) voltage a bit.

Oh, i have something like that too. My PC can't recognise my Canon A530 photo cam and actually some other USB devices with the stock FSB.

I could also be PSU, as USB devices draw power, and maybe overclocking has drawn up most of the available power.

I had a lot of really strange USB issues with 3 of my nforce4 ultra motherboards - maybe you have a chipset with buggy USB.

I had this problem with an nforce4 board as I overclocked. One was a super high ping. I fixed it with a system driver update.

Then I had trouble with my mouse and keyboard lagging the same as you explained. When I had Ntune running I'd get the occasional lag and ntune was showing crazy clocks for everything. Like 27,000 mhz and 900 mhz ddr1 speeds. I quit using ntune and my problems vanished.

Coincidence?

If something is still unlocked in the BIOS, you could have a component trying to run past a speed it should, such as PCI bus or similar.

you need to up the SB voltage for usb.

Try connecting the USB devices through a powered hub, so that no power is drawn from the computer's USB jack.
