DDR memory timing?
I bought a 1 gig Corsair dual channel kit for my A8N-E. The memory
timing says 2-3-3-6. Can somebody tell me what those numbers mean? This is my first system build. |

These are the RAS/CAS timings. In general terms, the lower those numbers are, the lower the latency of the RAM is, and is therefore "faster". Your motherboard should automatically detect the timings and adjust your BIOS for you. Your motherboard may not properly detect the voltage. Many motherboards will default to 2.5 volts for DDR, whereas the Corsair need 2.7 - 2.75 volts. FWIW, Corsair RAM is among the very best RAM made. You made a wise choice in choosing it. Bobby |

There is a presentation here on memory - slide 24 shows param order. http://corsairmicro.com/corsair/prod...707/index.html Paul |

This is my first system build. For AMD chips, the CAS latency is rated as 2.5 by Corsair and is set that way by default in the A8N-E bios. Here is the text of a forum answer by the "Ram Guy" at the Corsair website support forum: http://www.houseofhelp.com/forums/sh...ad.php?t=38919 "...set the Dim Voltage to 2.7X volts and you can use this a reference to set the timings. Dim Voltage 2.7 Volts CAS Latency CL=2.5 Row Cycle Time tRC Bios Default Row Refresh Cyc Time tRFC Bios Default Ras# to CAS# delay tRCD 3 Row to Row delay Bios Default Min Ras# Active Time tRAS 6 Row Precharge Time tRP 3 Write Recovery Time Bios Default Write to Read delay Bios Default Read to Write Delay Bios Default Refresh Period tREF Bios Default" |
