PCI clock tracking HT Bus?

[pclegodude39]

I use nTune for basic overclocking stuff, and it always worked just fine. Then I installed BF2. I'm not sure what happened, but when I start up nTune I get this warning message:

Warning: Your PCI clock is currently set to track the HT bus. If you adjust the clock for the HT bus, the PCI bus clock will change as well. Please consult your motherboard manual to determine how to disable this behavior before proceeding.

What does this mean, and how do I fix it? I've looked in my BIOS and can't find anything that can fix this. I've read my mobo manual cover to cover and can't figure it out. I have an ECS KN1 Extreme nForce 4 Ultra. board.

Any thanks will be welcome.

I think this means that as you raise your HT bus to achieve a higher oc, you will also increase the PCI bus which you don't want to happen. Raising the PCI bus can adversely affect other devices that don't take well to overclocking. Look in the bios for a PCI lock that allow you to lock the pci to 33. On AGP equipped mobo's you'll find an AGP/PCI bus lock which needs to be set to 66/33.

I've got a PCIe equipped board. I'll take a look.

I've looked in my BIOS, and I can't find anything even related to that. Would clearing the CMOS fix this?

instead of using nTune, try using the BIOS. its much more stable and gives you more control than software OCing does. in the BIOS you can lock your PCI bus to 33MHz, something you cant do with nTune. once your PCI is locked, then you can play with all the HTT you want.

yeah, but that's not what the problem is, I can't find how to lock my PCI bus. WHat do you think about clearing the CMOS or flashing the BIOS?

[pclegodude39]

I tried flashing the BIOS and clearing CMOS, still not working. I was hoping that after flashing the BIOS, I would be able to find an option that would allow me to lock the PCI bus, but I guess not. Next I'll try to do a system restore.

Are you looking in the bios for the lock option? Or are you still using the oc program?

[pclegodude39]

I am still looking for it in the BIOS.

That has absolutely nothing to do with finding a PCI lock option in your BIOS. If it's not there, it's not there. You just won't be able to overclock that machine much at all. You push the PCI bus very far out of spec and you're going to have problems, fast.

But what I don't understand is why it got all messed up in the first place. And how did it get changed? It used to work perfectly normal.
