H87 The H87 chipset is very similar to Z87, but lacks a few important features including CPU overclocking. While this chipset can easily handle SLI/Crossfire configurations by allowing the 16 PCI-E lanes from the CPU to be divided into either a single x16 slot or dual x8 slots, it does not support triple SLI/Crossfire configurations.
Like Z87, H87 supports Rapid Storage Technology, Smart Response Technology (otherwise known as SSD Caching), six SATA 6Gb/s ports and six USB 3.0 ports. Unlike Z87, it adds Small Business Advantage support, but removes support for Lake Tiny (SSD caching performance and power optimization). Finally, it supports two DIMMs per memory channel so it will be able to utilize up to four sticks of RAM.
H87 provides most of the same features as Z87 including plenty of SATA 6Gb/s and USB 3.0 ports. The only major features it lacks is CPU overclocking support and support for triple SLI/Crossfire configurations. Unfortunately, many motherboard manufactures attempt to push users to Z87 motherboards by limiting the number of ports and headers on their H87 motherboards. Because of this, Z87 motherboards are sometimes a better choice than H87 even when you do not need overclocking or triple SLI/Crossfire.
