Despite the fact that the personal computer in the form in which it is used to see the majority of people, is not a "thing in itself", and usually has an open architecture, so many users do not even come up with the idea to open the case andtry to change something in the configuration of the computer personally.But sometimes, due to some failure, even frankly "Dummies" have to pick up a screwdriver, to dive into the depths of his electronic assistant.
One of the most common failures of computers linked to the failure of the memory.According to rumors, in the service centers when an unspecified "diagnosis" in the first place it is replaced by RAM, and then 2/3 of the problems go away.In addition, the user may choose to simply increase the amount of memory your computer.In these cases, there is a problem how to select memory.
Maybe for some it will be a surprise, but the "RAM" is of various types, and the memory of the same type into the socket, designed for a different type of memory, without the hammer is not inserted.Now most of the market takes memory standard DDR3.In the warehouses of some stores still have a number of motherboards with support already outdated standard DDR2.Older standards (DDR and SDR) in new computers are not used for a long time, but a small supply of new memory modules (at inflated prices) is.So before you select RAM, you should decide what type of RAM is right for you.This can be done in different ways.Probably the easiest is to use different tools to determine the configuration of your computer.Here are some of them: CPU-Z, Aida64, HWInfo.Among them are many programs distributed under freeware.These tools will help to know how many channels of memory supported by your motherboard.Most computers, collected over the past six years, support dual channel.Some are quite expensive - three.Single-channel memory sunk into oblivion with the cessation of manufacture AMD processors socket Socket 754.
next step on the difficult path of resolving the issue of how to choose a memory, the memory frequency is the choice.Most of the low cost of memory type DDR3, offered now in the market, working on the effective 1333 and 1600 MHz.This is sufficient for most modern computers, and these modules are seamlessly supported by new motherboards.Memory less frequently choose not to be working, with greater - should be well aware, for what you overpay.
Normal RAM modern computer - 4 GB (two modules of 2 GB of each).It is possible and more memory is never too much, but how to choose a memory of this size, you need to make sure whether your motherboard memory strip of more than 2 GB.Check it out, you can guide that came bundled with your "nurse" when buying a computer.
manufacturer of memory can be distinguished Samsung, Hynix, Kingston, Kingmax.They all have an assortment of inexpensive memory for the average home computer.Of the more expensive brands of "enthusiast" actual production of memory OCZ, Corsair, Patriot, GEIL.As a rule, it - an expensive high-frequency memory for computers or productive to overclocking.
If you could choose memory in the store, with the question of how to install RAM in your computer, you have a problem should arise.Connectors ("slots") to install memory located on the motherboard, usually to the right of the CPU.If there are free slots, insert a freshly bought units in them, it is advisable, following "channel" (ie the number of installed memory modules must match the number of channels, as mentioned above).If there is no free slots, remove the old modules - because they are smaller volume!When installing, do not apply excessive force.If all of the above rules are observed, the memory module should be no problem, "sit down" in the slot, and then latches on the sides of the slot automatically lock in place and lock the module.If they do not snap into place, then the module is inserted incorrectly or not fully.Of course, all these manipulations should be done with a computer, completely disconnected from the mains.
still tells how to choose a memory for a desktop computer.Select the memory for notebook can be on the same principles, but, of course, when selecting it is necessary to look at the special "the notebooks" memory modules (they are half as long and, therefore, twice as less intensive than conventional modules).In addition, the notebook is more common hardware incompatibility with other components of memory, so either you must immediately go to the store with his noutom to on the spot to verify the absence of conflict or negotiate with the seller about the possibility of a replacement or refund.
