If your device is not new, there is no way to find out your actual clock settings. Simply try some lower frequency(1MHz, 500KHz, 100Khz) and read the device. If you can't get it working and you're using crystal oscillator, verify the clock on XTAL1 pin. If the clock is not present, you have to get clock from the device allowed spectrum from any clock source to this pin. After you do this and your device is still not communicating, that means, that the SPIEN fuse bit is unprogrammed and the SPI interface is disabled.
