okay, i have confused myself and need to be rectified.. When doubling the amount of RAM in a given system do you lose any throughput speed, like when jumping from 4Gb tpo 8GB to 16GB to 32GB etc, was this true with earlier chip-sets but is no longer an issue, please explain..

hi,

No unless you break the dual / triple channel. This happens if you pair different size module (Example 2 gb with 512 mgs,) if you keep half the size, you don't lose the dual channel (1 gb with with 512 mg).

Today you also have to be careful with the timing also (cas)

No you don't lose anything when increasing memory amount. However if say you have 8gb and never use more than 8 gb, upping the memory to 16 gb won't help you at all. If you only need 8 gb you're better off buy 8gb that are fast than 16 gb that are slower.

In a nutshell, i was told to use the fastest RAM the CPU/motherboard will support w/o overclocking and the lowest C/L, is this true for the most part and how do you determine what is the best C/L, what factors are involved in choosing C/L ?

Look for the timings on the kit something like 9-9-9-24 the lower the FIRST number the better the kit. Also pay attention to voltage, a kit that is 9-9-9-24 @ 1.5v is a much better kit than one at 9-9-9-24 @1.65v. The lower voltage means more OC headroom if you want to go that route. and well less heat pumped into your room.
