CAS Latency Range tCAS: 3-7; tRCD: 3-6; tRP: 3-6; tRAS: 5-18

MSI includes the most important overclocking adjustments at wide enough ranges to suite most users, including HT and PCI-Express clock adjustments that go well beyond the capabilities of the components they control. CPU core voltage is also aggressive at up to 1.80 volts maximum, while DRAM range is a little more conservative at 2.50 maximum volts.

MSI’s Cell Menu contains the most frequently used overclock settings, plus a few submenus for advanced controls. Minimal scrolling is required to reveal everything from the TLB bug fix control…

…to spread spectrum settings. Unlike ASRock, MSI differentiates the labeling of the CPU’s memory controller and the motherboard’s “Northbridge”.

Unlike many of MSI’s Intel boards, this Socket AM2+ equipped model has “Automatic” configuration settings for individual timings. This is a great improvement, since moderately experienced builders can easily set common timings such as “CAS Latency” but rarely know the correct value for tRRD.

The K9N2 Diamond provides two registers to store custom settings, making it easy to go back to a previous configuration after resetting BIOS.
