When does this bug happen? When overclocking the memory and CPU or when overclocking only the CPU?

I have this motherboard and I want to buy RAM at 1600 MHz (OCZ EB 4GB kit)and the Intel E8500. I want to OC the FSB up to 375 MHz aprox. (and fix the RAM to 1500 MHz), doing this the corruption may happen? I have 2 SCSI drives 15000 rpm and do not want to put them at risk.

If I can't do OC to the CPU, this memory works right at 1333 MHz?
