PCI/AGP Locking not supported by Motherboard.

post #1 of 4
Thread Starter 
As the title states i am unable to lock AGP/PCI, and therefore unable to overclock past 225Mhz. I'm using the Asus K8V SE Deluxe motherboard, based on the VIA K8T800 chipset. Is there anything i can do to get past this (short of buying a new motherboard)? Any programs that allow for locking or methods to further the FSB?

"Suppose that we overclocked a Duron processor from 100MHz to 120MHz on the bus and it remained absolutely stable all the time. But when we increased the FSB frequency to 125MHz, some freaky things started happening and the system would even refuse to boot at all. Of course, we could have reached the top of the CPU overclocking potential, but it could be a completely different reason. What if the CPU can go much farther than that, and it is the higher AGP and PCI bus frequencies that do not let us continue? You can check it out pretty easily: set the frequency to 133MHz. In this case the mainboard will use different dividers to set the bus frequencies to their nominal values. If your CPU copes with this overclocking, you will be able to go somewhat higher."

Can i set the frequency to 233? Would that work/why?

Thank you

You sure it's not because you didn't lower your HT multiplier or your RAM multiplier?

Aye. I lowered multiplier several values, my HT Frequency to 400MHz, my RAM multiplier to a 2:1 ratio and upped my CPU voltage, yet was unable to go any further then 225MHz.

I'm certain it's the issue described here "However, the early Intel chipsets, SiS chipsets and all VIA chipsets do not know to lock the frequencies at their nominal values. In reality it means that if your mainboard is based on VIA K8T800 chipset, for instance, you will not be able to go beyond 225MHz FSB frequency during overclocking. Even if your CPU can do better than that, you will have to stop at this point, because the system will not recognize the hard drives any more, or because the integrated sound on your mainboard stops working." (http://www.xbitlabs.com/articles/cpu.../oc-guide.html)

To Mootin: I used your FAQ, and got a figure of 230MHz. Assuming that my PCI packs out at 37 rather then 38, the figure = 224.2Mhz, which would be almost exactly what i'm getting. Thus you reaffirmed what i already know: how far i can push it without corrupting the HD. Thank you for the advice but i'm still at a loss as to what i can do to increase my FSB.
