* DDR2 memory modules are not backward compatible to DDR based motherboards, due to incompatible module connections (number of pins), voltage and DRAM technology. DDR2 memory modules have a different key or notch than the same-sized DDR modules to prevent their insertion into an incompatible memory socket. Quick'n is available in single and dual channel memory kits.
† The information below will help illustrate the appropriate settings when adjusting the memory timings in the motherboard BIOS for optimum performance. Please note that these settings may vary depending on motherboard make/model or BIOS update.
Sample:
| Part Number | Timings |
| MQ3200A/512 | 2-3-2-6-1 |
| Timing | Definition | Abbreviations | What it does |
| 2 | CAS Latency | CL | Delay between activation of row and reading of row |
| 3 | RAS to CAS (or Row to Column Delay) |
tRCD | Activates row |
| 2 | Row Precharge Delay (or RAS Precharge Delay) |
tRP/tRCP | Deactivates row |
| 6 | Row Active Delay (or RAS Active Delay, or time to ready) |
tRA/tRD/tRAS | Number of clock cycles between activation and deactivation of row |
| 1 | Command Rate | CMD Rate | Delay between chip select and command |
Notice: All Memonex products are tested to meet our published specifications. Some system or motherboard configurations may not operate at the published Quick'n memory speeds and timing settings. Memonex does not recommend that any user attempt to run their computers faster than the published speed. Overclocking or modifying your system timing may result in damage to computer components.
