Good quality RAM, although more expensive, buys both stability and performance. They are generally poorly designed modules with dubious stability.
Would you buy a processor or motherboard from an unknown company. To start with, we need to consider a little memory theory to understand the choices available to us.
A unique feature of these chipsets is the asynchronous memory bus, which means that the memory bus can Acer Aspire V5-431PG Broadcom WLAN at a different speed to the front side bus FSB. The earlier KX chipset also supports a 66MHz memory bus. Can this be used on a MHz memory bus and is it worth the extra money. Memory designed to run at MHz is called PC and conforms to a stringent standard defined by Intel.

An important consideration for SDRAM is the rate at which it can transfer data to and from Acer Aspire V5-431PG Broadcom WLAN processor. This is illustrated in the figure below. As the memory bus is bits or 8 bytes wide, the memory speed directly determines the theoretical peak rate at which data can be passed to and from the Northbridge. This means that the FSB supports a peak data rate of 1.
VIA KT block diagram from VIA s website Memory Timings In practice, memory benchmarks show that is difficult to achieve an average data throughput that is even half the theoretical peak transfer Acer Aspire V5-431PG Broadcom WLAN on the memory bus. In simple terms, however, the memory cannot simply instantly provide data with each clock cycle. There is an initial overhead or latency associated with a request to read or write data from a given memory address, followed by the data appearing on each clock cycle.
It is hard to describe these overheads without repeating the detailed descriptions of SDRAM operations in the references above, but if for simplicity we simply regard the memory as a table with rows and columns, then Acer Aspire V5-431PG Broadcom WLAN principle delays are: Although measured in clock cycles, the underlying reasons for these delays are due to the actual time taken for signals to settle within the Acer Aspire V5-431PG Broadcom WLAN chip.
The timings are therefore specified for a given memory speed, and will change with bus frequency. It all depends on the quality of the RAM. To summarise all this timing technobabble, the point to realise is that the performance of the memory depends on not just the MHz but also on how efficiently the RAM uses each clock cycle.

To make matters more confusing, suppliers often abbreviate these timings to just the first number - the CAS latency, eg. It is up to you, as the buyer, to do your research. If a supplier doesn t provide this information, choose one who does.
What does this all mean to me. You want to know whether your computer will be more stable or faster, if you invest in some quality RAM. How does the CAS latency affect things.
How far can you overclock the RAM and how does this help. This is what this article attempts to address. For those of you who like looking at pictures, here it is: What more is there to say. It looks like any other DIMM.
The Benchmarks The most popular memory benchmark in use today is the memory benchmark within the popular SiSoft Sandra software. A popular gaming benchmark is 3DMark version 1.
I used this to see what impact memory would have on gaming. However, this benchmark gives a somewhat unscientific score with no units, and it is not at all clear how this figure is derived. Higher is better, but that s about all I know.
