PCIE Clock (MHz) Allows you to manually set the PCIe clock frequency. The adjustable range is from 100 MHz to 200 MHz. Auto sets the PCIe clock frequency to standard 100 MHz. (Default: Auto) HT Link Frequency Allows you to manually set the frequency for the HT Link between the CPU and chipset. Auto BIOS will automatically adjust the HT Link Frequency. (Default) X1~X13 Sets HT Link Frequency to X1~X13 (200 MHz~2.6 GHz). Set Memory Clock Determines whether to manually set the memory clock. Auto lets BIOS automatically set the memory clock as required. Manual allows the memory clock control item below to be configurable. (Default: Auto) Memory Clock This option is configurable only when Set Memory Clock is set to Manual. When you use a AM2 CPU: DDR 400 Sets Memory Clock to DDR 400. DDR 533 Sets Memory Clock to DDR 533. DDR 667 Sets Memory Clock to DDR 667. DDR 800 Sets Memory Clock to DDR 800. When you use a AM2+ CPU: X2.00 Sets Memory Clock to X2.00. X2.66 Sets Memory Clock to X2.66. X3.33 Sets Memory Clock to X3.33. X4.00 Sets Memory Clock to X4.00. X5.33 Sets Memory Clock to X5.33. When you use a AM3 CPU: X2.00 Sets Memory Clock to X2.00. X2.66 Sets Memory Clock to X2.66. X3.33 Sets Memory Clock to X3.33. X4.00 Sets Memory Clock to X4.00. X5.33 Sets Memory Clock to X5.33. GA-MA790X-UD4P Motherboard - 40 -
