System Memory?

[TheMJ]

What do I need to know about memory?
More specifically, What is Timing, how much faster is pc 3200 than whatever's slower, and what are some good brands?

Thanks 🙂

EDIT: Oops. wrong forum. d'oh! sorry.

3-4-4-8? what is that? ... its the latency or timing. eg a stick of 512 MB pc32000 ram with 2-2-2-5 will be faster than 3-4-4-8

Is there any perticular meaning to the #s? like I realise the lower the # the better, but, for example, is 4-3-3-3 the same as 3-3-3-4?

PC3200 2-3-4-5-1Twould have a clock rate of 200 MHz, CAS latency of 2 cycles, RAS-to-CAS delay of three cycles, RAS Precharge of four cycles, ACTIVE to PRECHARGE of five cycles, and a Command Rate of one cycle.

Tightest possible latency settings at a fixed, 200MHz (PC3200) memory bus frequency: These tight latencies will consist of a CAS latency of 2 cycles, tRCD of 2, tRP of 2, tRAS of 5, and command rate of 1T. This will be denoted as ?2-2-2-5-1T?.
More relaxed, ?nominal? latency settings, at the same 200MHz frequency: These nominal, relaxed latencies will consist of a CAS latency of 3 cycles, tRCD of 3, tRP of 3, tRAS of 8, and command rate of 2T. This will be denoted as ?3-3-3-5-2T?.

perfect! thanks, blodhi74!
