Cannot overclk Abit IC7-G

[trilogy777]

Can anybody help me please? Every time I change FSB to User - and try to overclock , I reboot and
my SATA hard-drive is not detected, so I get a System Disk Error.
I am using an Abit IC7-G mobo, 2.8GhzE P4, 512Mb of OCZ PC4000-500Mhz memory ,Thermeltake
420W Case

Are you setting pci/agp to locked 33/66?

If I set to "Optimum" defaults and CPU to User - 215 and thats it , the SATA HD is not detected...
the PCI-AGP is on Auto. Even when I Clear CMOS on MB and then set CPU to say...USER-210
the same result..........any other ideas?.......anyOne?????????

Thank you Lithan. I set the AGP/PCI ratio to "Fixed" and it works.My 2.8 is @ 3.2 now and
everything works fine..Thanks again for the tip

No problem. I used an IC7 before and I have an Is7 now. I just forgot they refer to locked as "Fixed". Glad you figured it out.
