    Hi,
    Please excuse my ignorance, I have just moved across from AGP to PCI-E and have just recieved today my new HIS Radeon 850xt IceQ 2 Turbo. Being a PCI-E "Noob" could someone confirm what the stock Clock speed is for the port. I am aware that AGP runs at 66Mhz stock but my ASROCK ALi 1695 Dual Sata II board allows me to determine the speed for the PCI-E x 16 port.

    I didn't want to potentially "fry" it at 133Mhz but then again, do not want to underclock it at 100, can anyone help please?

    Cheers

    100MHz is PCIe default clock. Leave it at default, it is better for overclocking.

    no reason to raise pci-e for general use ... it helps get around the i945 overclocking lock (only on that chipset), see the al8 review here for more info.. increasing pcie clock helps in some benchmarks like pcmark2004
