I notice that if I put my P570wm with Prema Bios to sleep, after I wake it back up, the PCIe is only 2.5Gbps, not 5 ?

Is this a windows power management thing, or is there a setting in the bios to keep it at 5Gbps ?

Find the manufacturer of the exact ddr ram you are using. The datasheet will indicate limits. How much they are overclockable depends on the bin of the ddr ram, which you can determine from the part number and datasheet. You'll have to look at the ram on the module, not the module manufacturer.
