Once again, ASRock takes the latest chipset, adds a ton of features, and sells it at a fraction of the price of competitor P45 chipset boards on the market. The board features quad core Yorkfield and dual core Wolfdale processor support out of the box without a BIOS upgrade and PCIE2.0 CrossFire support. In addition to CrossFire support, the P45R2000-WiFi allows for either DDR2 or DDR3 memory to be used.

Now that DDR2 memory is dirt cheap, many users want the opportunity to use DDR2 but be able to upgrade to DDR3 in the future when the memory becomes mature and prices come down.

ASRock found a niche here as with the P45R2000-WiFi, as there are very few DDR2/DDR3 P45 hybrid boards on the market.
