DRAM Timing Selectable (Timing Mode)
This is the main parameter for memory setting with the help of which manual or automatic mode of parameters settings are chosen.
- By SPD (Auto) – the parameters of memory modules are set automatically with the help of data from the SPD chipset; this is default value and it should not be changed unless necessary;
- Manual – the parameters of memory modules are set manually; when you select this value you can modify the settings of working frequencies and timings.
Configure DRAM Timing by SPD (Memory Timing by SPD)
The meaning of this parameter is similar to previous one “DRAM Timing Selectable) and possible values will be the following:
- Enabled (On) – the parameters of memory are set automatically according to SPD data;
- Disabled (Off) – the memory is set manually.
Memory Frequency (DRAM Frequency, Memclock Index Value, Max Memclock)
This parameter displays or sets the memory working frequency. In most cases this frequency is set automatically according to the information from SPD. If you set the frequency manually, you can make a memory accelerate, but not every module will be stable then.
- Auto – the memory frequency is set automatically according to the SPD data (by default);
- 100, 120, 133 (PC 100, PC 133) – possible values for SDRAM memory;
- 200, 266, 333, 400,533 (DDR 266, DDR 333, DDR 400, DDR 533) – possible values for DDR memory;
- DDR2-400, DDR2-566, DDR2-667, DDR2-800, DDR2-889, DDR2-1067 – the values for DDR2 memory;
- DDR3-800, DDR3-1066, DDR2-1333, DDR2-1600 – values for DDR3 memory.
In some motherboards this parameter is available only for reading. And to change a memory frequency, you have to use the parameter “System Memory Multiplier”.
