Memorie DDR2 Vs. DDR3 | are two different types of ram

What is ram you are using, Commonly that Random Access Memory (RAM) has changed over time. Towards the end of last century there was a significant difference between CL2 and CL3, depopulated when the PC133 or PC100 SDRAM. Today, the performance gap between fast and relaxed timing is almost nonexistent. The latencies of memory seem to have increased, from one generation to another memory (CL2 / 3 with DDR1, CL3-5 with DDR2, CL5 DDR3 and over with), but the changes are minor, because the frequencies are doubled to change of each generation. The actual latency, therefore, have remained more or less the same, while what is the throughput has increased considerably.

Memories for fanatics have another justification, based only indirectly on the performance: overclockers need maximum flexibility when they try to push a system to the limit. Increasing the frequency of the bus is often the only way to increase the frequency of the CPU, step that automatically increases the frequency of memory, which derives directly from the system clock frequency. No members are, of course, is willing to accept a limit imposed by the RAM, so the high-speed products are ideal for this type of activity. This scenario is valid only for the extreme overclocker, because the benefit of a faster than a slow memory is very limited, if the parameters and other components remain unchanged.

You should to Know how important timing and speed of RAM and both are two different type of ram . To reach a conclusion we have assembled an Intel socket 775 and used two different processors: the new Core 2 Duo E8500 45 nm with a frequency of 3.16 GHz and 6 MB of L2 cache, and an old Pentium 4 Extreme Edition 3, 73 GHz single core. We decided to include the P4 because it integrates a cache less and less efficient than the Core 2 Duo. Both processors have been tested with DDR2-667, DDR2-800 and DDR2-1066, and then with DDR3-1066 and DDR3-1333. Unfortunately it was not possible to test the P4 with the DDR3-1333, because that would require a 1333 MHz FSB
