overclock ok but cd-drives crap out?

[canfraggle]

I managed to get my XP 1800+ with an MSI KT266A K7T Pro2 board to run stably at 1.85v with 145 FSB but at these speeds the DVD drive and the CD-R crap out. Any sugestions?

Looks like you need to back down . Altough if you unlock it (which is child's play) you will be able to reach some nice speeds.

Why is the drive so senstive? I thought PCI and graphics cards were the most instable.

it can be anything... i remember back in the day some hard drives (maxtor i think) were having muchas problemas with 100mhz fsb

Executor: yeah that's what baffles me... the network card, sound card et al work fine. Just the CD-Drives die

 

[ugh]

Unfortunately, you have to back it down. I've got the same problem when I had my FSB at 120. Good thing that the CD writer craps out only when it is writing

Some PCI components just didn't like the out of spec PCI bus.

You can try moving around some of your PCI cards or hard assigning them IRQ's. The IDE Bus sharing an IRQ with PCI devices can give your system fits, even if there aren't any IRQ conflicts. Try using the lower numbered PCI slots (1,2,3) first as they have priority over Interrupt Requests.

I moved some cards around when I reinstalled my Lite-On 24x burner..was running fine at 150mhz FSB, but after the swapping and install, and Windows wouldn't finish loading at any speeds higher than default! Moved the PCI cards back to their normal places and I'm back raging along at 150mhz FSB.

If you're having problems with the mobo on-board IDE controller and high FSB's, consider getting one of the "TX2" controllers by Promise, which can run at up to 66mhz PCI bus.
