OK, I responded to your question in another place already, but here goes again, YOUR CPU IS NOT FRIED. If you connected the L1 bridges from the start, before ever firing up the motherboard once, then put the L1 bridge connected CPU in the mobo and fired it up, than the motherboard is telling you that it cannot read from the CPU what speed it should be set to. So your 800mhz CPU is telling the motherboard, "What do I do?" and defaults to 600mhz so it can at least run if you press F1 to continue the booting process. You need to go into the BIOS, enter the CPU setting and set the CPU to 800mhz, default for your 800mhz CPU and get your system running. BE SURE TO INSTALL THE VIA CHIPSET DRIVERS!!!!! I would go to www.viahardware.com, look for 4-in-1 drivers on the left, and download version 4.28, unzip them, and install them by running the setup. You will need them to make the system stable in Windows. After all is good in Windows, commence the overclocking. I would go straight to 1Ghz, with the voltage set to 1.85V, you CPU runs at 1.70V at 800mhz.
