However, your motherboard must support this kind of overclocking ( read our tutorial on memory overclocking for more details). Thus buying a memory module with a labeled clock rate higher than what your system supports is useless if you are not going to overclock your system.įor the average user, that is everything you need to know about DDR, DDR2, and DDR3 memories. Since the manufacturer guarantees that these modules will run up to 2,133 MHz, you know that you can raise the memory bus clock up to 1,066 MHz to achieve a higher performance with your system. So, why would someone buy these modules? Someone would buy them for overclocking. Why should or shouldn’t you buy these modules? So, they won’t automatically run at 2,133 MHz nor automatically achieve the 17,000 MB/s transfer rate.

If you install it on a regular PC system supporting DDR3 RAM memories, they will probably run at 1,333 MHz (DDR3-1333) – which the maximum DDR3 RAM standard speed –, achieving a maximum transfer rate of 10,664 MB/s (or 21,328 MB/s if they are running under dual channel mode, read our tutorial on dual channel to understand more about this subject).

This is the maximum clock rate they support, not the clock rate at which they will be running. Even though they are labeled as DDR3-2133, they won’t run at 2,133 MHz automatically on your system. How do RAM memories work?įor example, let’s say that you bought a pair of DDR3-2133/PC3-17000 RAMs. Actually, this is a very common misjudgment. If the memory module is installed on a system where the memory bus is running at a lower clock rate, the maximum transfer rate the memory module will achieve will be lower than its theoretical maximum transfer rate. Maximum Theoretical Transfer Rate = clock x 8 As 64 / 8 equals 8, we can simplify this formula to: Since DIMM modules transfer 64 bits at a time, “number of bits” will be 64. Maximum Theoretical Transfer Rate = clock x number of bits / 8 The maximum transfer rate for a memory module can be calculated through the following formula:
