PCI cards not working

[oznerol]

My setup:

MSI Neo4-F mobo
A64 3000+ Venice
(currently) 512MB PC3200 Mushkin value ram (3-3-3-8)
X800XL
Antec 400W Smart Power PSU

I normally have 1 gig of ram, but one was DOA, so I sent it back - I should have the 2nd stick in a few days.

Anyway, I'm attempting to overclock, and everything is going fine - I'm working up, seeing how high I can get.

I get up to 2Ghz - 9x mult, FSB = 222, 1:1 ratio.

Memtest shows no errors. Windows boots up fine. I figure 2Ghz is low for this CPU as I've seen other get much higher.

The problem is, at this speed, NONE of my PCI devices work - aside from my PCI-E x800xl.

I have a wireless card, sound card, and tv tuner on 3 PCI slots, and none work - but THEY ARE DETECTED, and windows says they are operating normally.

I'm not going higher, as I want to resolve this issue first. My PSU has 18A on the 12V rail, I figured that was plenty. I currently have it at 1.935Ghz - 9*215.

Any ideas?

maybe you are overclocking your PCI bus, it should 33 mhz btw

Lock the PCI bus man.

Sounds exactly like your pci bus overclocked to high. Make sure you set it to 33 Mhz before overclocking, as it will automatically go higher when you increase you htt. It isnt meant to be oced like your cpu.

I've locked my PCI Bus by setting "CPU Spread Spectrum" to disabled instead of center spread (it's how my motherboard does it, apparently), and still get the same problem.

Anything I'm missing?
