OCZ EL DDR PC-3500 Gold GX Dual Channel Memory Kit
 

Upgrading your computer's memory is one of the most worthwhile
upgrades you can do. In addition to being the cheapest way to give your
computer a noticeable boost in overall performance, a memory upgrade is
arguably the easiest to perform. A long time ago, memory upgrades referred
strictly to capacity. Nowadays, the speed of the memory has also become
important. Sure there are plenty super cheap value memory sticks available.
They are capable of running at their specified stock speeds, albeit at very
relaxed latency timings. For a little more, you can get a set of
"affordable premium" memory modules that not only run at their stock
speeds, but go far beyond that while maintaining tight latency timings.
Case in point: OCZ's Gold series. OCZ's Gold series offers superb
performing memory modules with low latency timings.
