Because last week I made a upgrade de RAM to a laptop / notebook Toshiba and I encountered some problems related to compatibility Between the memoirs, I think it would be interesting to know a few things before you buy a RAM memory for a laptop.
This item will be useful to users who want to do upgrade de RAM (besides the memory already installed to come with one more to supplement), as well as to those who wish to Change RAM memory to notebook.
1. Before you think of a upgrade de RAM, make sure the laptop supports your desired upgrade to check which is the maximum of RAM supported of your laptop search the exact note of the notebook pe the manufacturer's website and consult the sheet of Technical details its.
What do I mean when I say “the exact model of the laptop“… Some brands, Toshiba For example, besides the model series (eg. Toshiba Satellite A300) they put another series. An example is the laptop they are now. Toshiba Satellite A300 1QE PSAGCE. To check how many GB of RAM supports my laptop, I go to the official support website from Toshiba and see:
This is true for all models of laptops / notebooks. Acer, ASUS, DELL, HP, Lenovo, MSI, Samsung, Sony If etc…brands.
2. Make sure you have Free slot on the motherboard, for additional memory. If you have 2GB RAM Install, there are two variants. 1GB x 2, which means you have two RAM modules and no free memory / upgrade extension slot, or 2GB x 1, that is, a single pleasant RAM and a free slot, available for installing a new memory. The most unfortunate case is 1 GB x 2, because in case of an upgrade to 4 GB, you will have to Give up both memoirs and buy a 4 GB mode (recommended) or one 4 GB kit ( 2 GB x 2). The upgrade to 3 GB in this case is slightly cheaper than the first option. Replace a 1 GB module with a 2 GB.
Most notebook models have only two slots for memory. The slots can be found somewhere on the back of the laptop, under a clap. If that clap that allows access to the memoirs, is caught with a screw (and that's the way it is most), and your laptop is under warranty, I suggest that the RAM upgrade or the physical checking of the slots will be done in the service or in the store where you purchased the product.
A check “soft” a modules and RAM slots can be done with Rammon application.
Download Rammon for operating systems on X86 (32-bit) and x64 (64-bit)
{Filelink = 35}
*compatible Windows XP, Windows Vista and Windows 7.
In the archive above, there are two variants (32-bit and 64-bit). Install the variant for your operating system. (To find out How many bits is the operating system, to know This tutorial). Install and run the application RAMMon. The memory modules will appear on two columns. If under “Module #1” or sub “Module #2” Nothing appears (ie memory information), then you have only one RAM.
3. Good. We have a free slot and our laptop support more memory than we currently have installed. So that we can upgrade, we need a Compatible memory with the existence (which suppose that is original memory, compatible with motherboard – motherboard), and for this we will have to know all the data about the memory already installed. In this problem, all the Rammon application, above, helps us.
We must consider the following data to check compatibility:
– the type of RAM (ex. DDR1, DDR2, DDR3, etc. DDR and what else. There are many new types appeared)
– standard name and the name of the mode (ex. DDR2-800 and PC2-6400, in my case)
– the type of mode (ex. SO-DIMM).
– latent supported by module or CAS/CL. (ex. Cl5, CL6, CL4 …)
Although in the case of laptops latent of memory (Column Address Strobe (How to write CL) is very important, both some manufacturers and magazine online care I sell the ram memories For laptops, forget to specify the CL in the product sheet.
I tested for upgrade a few modules that had all the above data identical to those of the original memory (ie DDR2-800 / PC2-6400 / Sodimm), less CL. The original memory has CL6, and the memoirs tested by me had Cl5. The smaller the latency, the better, but if two modules are installed on a laptop Cl5 and one of CL6, then surprises like blue screen (BSoD) when the operating system requires both memories to work in parallel. It happens to me when the consumption of RAM was greater than 2 GB. Appear the blue screen with messages of error, and the laptop se Restarta Automat.
To see what CL has the RAM installed on your PC or laptop check in RAMMON report, lines: CAS Latencies Supported and Timings @ Max Frequency. If these are: 4 5 6 and 6-6-6-18, then the CL is 6. I mean CL6. Seek to Buy a compatible memory in all parameters with the one installed on your laptop
This is true for desktop-hate. As far as I understood, there are motherboards and controllers that accept different latent memories, but for stability and performance, it is very indicated that the supported latencies are identical.
Here's what a case looks like in which both memory modules are compatible: RAMmon.txt (The module Samsung is the original one, and the one Kingston is identical)
4. After you have all the information about the RAM of your laptop you will only be looking for best price to purchase a RAM.
I searched the specialty stores in the city (province) and found memories at Purchased prices (~ 200 ron) , compared to Prices offered by online stores. If you decide to make a Order online (I recommend online shopping), you have to consider a few things (valid for everything, not only for PC memories and accessories).
– Make sure that the site you make belongs to a confidence company / companies. Look for reviews of the online store. Forums, blogs, etc. TRUSTED sites. recommend emag.ro and evomag.ro cu Refund payment (that is, when receiving the parcel).
– Make sure you found the lowest price for the product you want in my case I had a proportions. 2 GB Kingston RAM with the configuration in the report above, at the city stores was between 195 – 200 RON, pe eMag: ~ 170 ron (156 ron at present), and on Evomag : ~ 115 RON.
It is to be specified that eMAG offers transport included in the price of the product, and at Evomag (where I gave your order) I paid 21 RON The transport, but it was still a better price at Evomag. With ~ 35 RON smaller than eMag and with ~ 65 RON Compared to the prices in the city.
Do not understand from this that eMAG has higher prices compared to Evomag. When you have to buy a product, it is good to follow all offers. And on Evomag I found many products at prices higher than eMAG. Price differences appear Depending on the product And not necessarily depending on the store.
Personally I can recommend both stores. to Evomag It was the first order and I am very pleased. Good price and Prompt delivery. About eMAG I can say the same thing about other products. Even today I was delivered an order from eMAG. I waited for a week the delivery, but the product required by me was not in stock and I was immediately announced as I was waiting. Otherwise, for the products on the stock, the eMAG was impeccable.
