The SPD tab in CPU-Z shows what frequencies, timings, and voltages are available for running that particular memory module.

The "Frequency" as shown in CPU-Z refers to the clock frequency that is supplied to the memory. But since the memory is Double Data Rate (DDR), the memory actually runs at two times the clock frequency. For example, if the Frequency shown is 1090 MHz, then the memory will run at two times 1090 MHz = 2 x 1090 MHz = 2180 MHz (or 2180 MT/s ~ Mega Transfers of data per second).

Usually, the memory frequency, timings and voltage is selected automatically by the computer system (BIOS) when memory is installed. But manual selection of memory frequency, timings and voltage which overrides automatic selection is usually possible by changing settings in the system BIOS.

Manual override of memory settings is not usually done unless the automatic settings are not what is wanted, particularly when wanting to overclock the memory.

Manual memory settings requires entering system BIOS and changing DRAM Voltage, DRAM Frequency, and DRAM Timings using the values shown under the SPD tab in CPU-Z.

For example, if wanting to run the memory according to "JEDEC#8, then the memory frequency should be set to 1200 MHz; the timings set to 17 for CAS latency, 17 for RAS to CAS, 17 for RAS Precharge, and 39 for t[sub]RAS[/sub] (the other t[sub]RC[/sub] timing is not so important); and the dram voltage set at 1.20 V. These settings should then be saved and the BIOS exited and the system rebooted for these settings to come into effect.
