cas latency

[Nagasama]

how important is latency in ram? what is a good number for an amd 64x2 4200+ windsor? i heard lower=better with amd...
i notice the numbers are listed with the upper end kits on newegg.
two part question, actually...
how important would latency be to an e6300 conroe?
thanks

e6300 is not a conroe, it is an allendale. i would say CAS latency isn't that important to either when compared to frequency. if it was s939 i would say CAS is important. lower CAS is generally considered better but i wouldn't go out of my way to pay more for lower latency DDR2 when you can get higher frequency.

ok thanks, that makes sense.
as far as the allendale...does that name include the 6300 and the 6400?
if so, what are the differences between conroe and allendale?

 

[Trifid]

Allendale have less cache compared to Conroe. (2Mibs Vs. 4.)

Latency is the delay in which two devices communicate. The lower the delay, the faster instructions/commands can be interpretted.

You probally won't notice a difference between 3 and 2, except for benchmarking - but it depends really on the quality of the RAM.

i ordered this ram :
http://www.newegg.com/Product/Product.asp?Item=N82E16820145034
expensive, but i figure you get what you pay for (mostly)
i will be using it with a amd 64x2 4200+
i notice the latency of this ram is 4.
it seems the lower mhz ram has lower latency.
nitestick says frequency better than latency, eg. 800mhz latency 4 better than 533mhz latency 3?
argggggggg....
this ram should be okay, wouldn't you think?
i hope i didn't screw up...just ordered it today and this is my forst time building (and i don't know jack)
in most of the reviews of this ram people say that the timing is better than the 5-5-5-12,and worth the extra 20 bones.
jeez, i don't even know what that means, really...
