PCShopTalk posted a review on the ASRock P45DE Motherboard

In the Overclock settings submenu, we can set the CPU host clock, the DRAM frequency, but also the FSB to MCH strap (very useful function, which allows higher CPU overclocking when we have a small number of memory dividers, like this board does have). Here we can set also the voltages for the CPU,DRAM, NB,SB, GTLs and so on
