How we choose the Memory
Quick review of Memory technology
With memory it's all about how much. A shortfall in memory results in a
significant drop in both capability and performance. If your computer is slow
the first place to check is not the CPU, but the amount of memory!
2 GB of memory is what we think is good currently. Windows XP and Vista
32-bit can only handle 3 GB of memory anyway, no matter how much
physical memory you put in. While 2 GB of memory used to be expensive,
fortunately, memory prices have become attractive and we're going to take
advantage of that.
Once we've got enough memory we look for performance. The two variables
here are latencies and clock speeds. If you've got to pay a heavy price for
low latencies and high clock speeds it's better not to. That saving is better
spent on the CPU chip, graphics solution or hard drive where a larger
performance gain will be seen. Fortunately again, with memory prices falling
some memory sticks amazingly give you low latencies and high clocks at a
great price!
Dual channel DDR2 memory is the current tech we like. DDR3 has come but
is yet to be compatible with some motherboards and chips. Also, DDR3 runs
at greater latencies so it requires much higher clock speeds to have any
significant edge over DDR2. So for now DDR2 is where it's at.
