Advice 2: How to increase RAM
- To increase memory virtual method will need the ability to work with a computer, physical way - the new RAM modules from a computer store.
Virtual way to increase memory is that for its expansion would need to clear the memory from unnecessary processes. To view the level of utilization of the RAM, call the task Manager with CTRL+ALT+DEL and You will see how many megabytes of memory it takes for each running process. The output is clear: if You want to reduce the load on the RAM and thereby increase memory virtual way, disable all visual effects and increase the swap file (system Properties", section "Performance"), remove the Wallpaper from the desktop, as well as "widgets" and unnecessary programs that use the autorun.
Owners of laptops will have more difficult – if You are not an expert, it is better to seek help in increase the RAM in service.

Advice 5: What is the timing of RAM
The progenitor of computer memory was created in 1834 by Charles Babbage. It's a mechanical device, referred to as "the Warehouse" (store), retained intermediate results of calculations in the "Analytical machine".
The latency or timings, show the number of cycles spent on internal operations, in other words, the timings characterize a simple memory.
The principle of memory access
For understanding of those or other timings is more focus on the memory access. Simplified memory chip can be represented in the form of a table, where each cell corresponds to a memory element storing one bit.
When selecting a cell via the address bus is the number of column and row. The first gate pulse is supplied to access the string — RAS (Row Access Strobe), then the momentum of the column access CAS (Column Access Strobe).
After selecting a cell on it are sent to various control pulses — tolerance check to write, write, read or recharge. And between these operations there are delays, which are called timings.
There are four different timing specified by manufacturers of memory modules.
CL (CAS latensy) – CAS-delay is the wait between the CAS pulse and the beginning reader. In other words, the number of cycles required to read the cells if the line is already open.
T RCD (Row Address to Column Address Delay) – delay between RAS and CAS pulses. The timing shows the time between the opening line and the opening of the column.
T RP (Row Precharge Time). The timing delay between the pulse to close the active row and the RAS pulse on the opening of the next.
Sometimes you can meet the entry type 6-6-6-18-24. Here, the fifth number indicates the timing Command rate — the delay between the pulse on the chip select module memory and activating a row.
The sum of these values characterizes the delay between reading specific memory locations, if opened another line. Manufacturers often specify these three parameters, but sometimes you can see the fourth - T RAS.
T RAS (Row Active Time) – the number of cycles between RAS-impulse and momentum closing line (Precharge), that is, the update time of the row. Usually T RAS equal to three previous timings.
For convenience, timings lead without the designation using the hyphen, for example, 2-2-2 or 2-2-2-6.
Advice 6: How to increase RAM on computer
Why you may need to increase the amount of RAM on the computer?
Unfortunately, many developers of operating systems and software (programs and games), absolutely not thinking about optimization, don't remember that many users can not constantly buy the most modern hardware, so their creations can "slow down". To partially solve this problem, you may need to increase the amount of RAM on the computer.
How to buy the right bar of RAM?
When you purchase straps of RAM should be remembered that different types of RAM are not for the each motherboard. To choose the right bar for the memory, it is necessary in the documentation to see the exact model name of the installed motherboard. View the description of this motherboard model on the manufacturer's website, which should state what type of memory suitable for work, as well as the maximum amount of memory that can "see" the motherboard. Also from the description you can see the number of slots to install RAM.
Determine the available computer RAM. To do this, turn on the computer, click on the icon "My computer", right-click, then select "Properties", tab "General" and you can find the total amount of installed RAM.
From the data your task is to calculate the amount of planks that you will acquire (if at least one slot for RAM on your motherboard free, then you just have to subtract from the maximum possible amount of RAM amount of RAM installed, otherwise it will be necessary to pull one of the straps, smaller volume, and in its place set a new benchmark, the volume of which is also calculated).
After buying new memory modules, remove the housing cover (depending on the model it can be removed entirely or have the option to remove just the cover on the side). Look closely at the installed available strap (strap) of memory. In parallel, they place a new bar and insert it in a free slot. Strap memory must enter into the connector tightly to not have been visible contacts and must work the latch, which additionally keeps the bar in the connector.
The diagram below shows an example of changing memory modules DDR2, but it is not necessary that you will also have this type of memory, but the appearance of the connectors under the RAM and the memory modules are similar and you should also consider the location of the notches in the circuit boards.
If done correctly, the above tab will display more memory than before.
