Default RAM Timing?

What is timing when it comes to RAM? I saw on 2x1GB sticks that the timing was 3-4-4-8. What does that mean?

Timings show you the latency of the ram... the lower the better.

Tthe lower you can set those timings the more you can increase the Rams Memory Bandwidth (more Bandwidth = Faster). (also note though that there are a lot more Timing options in BIOS that are shown then just those 4 settings)

The lower the Latency also the more stable the ram will be if you Overclock the Ram... because you have more room to Raise the Latency for stability.
example -

my 1GB ram set to 3-4-3-8 (command rate 2T), memtest86+ reports -
Bandwidth about = 13,500mhz

2.5-3-3-6 (command rate 2T)
Bandwidth abotu = 14,500mhz

2.5-3-3-6 (command rate 1T)
bandwidth about = 15,500mhz

well like jolancer was saying the lower is better but, with fast memory with low timmings you will need a bit more voltage running to it than regular high timming memory, your average pc3200/ddr400mhz memory with timmings 222-5 would use about 2.7-2.85v. but the memory i am running is geil ultra ddr500/pc4000. timmings 2.5-337/ 2.9-3.2volt, so most likley the higher mhz the memory will be timmed higher. but some memory modules like voltage for example say some memory is 3448 timmings pc3200 2.6-2.7volt you could proubly run 3.2volt to it and crank it to 2336 timmings pc3200, ive seen my memory run at 2336 @256mhz effective 512mhz! with 3.5volt to it, and these results were dont on a p4 3.6 with the ocz dimm booster, so make sure you can always run a little more voltage to you memory.
