In the DRAM configuration page, you can adjust many of the settings available as shown above. Some of the common ones include CAS Lantency, trp, trcd, tras, trfc etc..

HT Frequency is known as LDT Bus frequency. This is where you specify the HT frequency which will be multiplied by the CPU CLK and it should be around 1GHz. e.g. 200x5, 300x3.

In this screen, you can set the PCIe to run at the specified link width, be it 8x or 16x. If CrossFire is to be enabled, dual slot configuration must be enabled and GFX0 and GFX1 must be set to x8.

CPU or HTT or CPU CLK is where most of the action begins in overclocking. The range available for this board is  200 to 440MHz.
